The World Economic Forum says that this is finally changing. They published an article titled 2024: a tipping point for investing in sustainable buildings.

“Building owners are facing the rising costs of climate risk but also growing transition risk, including tightening policy and regulation, evolving market expectations and wider societal pressure. This has big potential implications for the value of their assets and the income they generate… Most importantly for both owners and occupiers, we believe 2024 will be the tipping point when the value creation and returns for these investments in sustainable office buildings will start to pay dividends,” WEF author Guy Grainger writes.

The market for green buildings was will be wororth $238.91 billion in 2021 and is projected to be worth over $383 billion by 2030. The growing demand creates all kinds of opportunities for companies and investors catering to sustainable construction practices.

Factors Driving Demand for Green Construction

Green building projects are becoming a lot more popular these days. A number of factors are driving interest in them, which is creating opportunities for investors. Some of the driving factors are listed below.

New Government Initiatives in the US and Europe

The World Green Building Council reports that a number of changes have created more demand for green construction than ever. On April 4, 2022, they responded to the new EU Energy Performance of Buildings Directive, which is going to play a huge role.

New regulations geared towards lowering the global carbon footprint will mean more companies have to construct sustainable buildings. Green construction companies and their investors will stand to benefit.

Realizations Made During the Pandemic

The pandemic has really fueled investor interest in green building projects. Many people all over the world finally realized how vulnerable our world is due to changes brought on by the pandemic. Many people are more concerned about climate change as a result.

Investors recognize these developments and want to take advantage of growing demand for companies focused on sustainability.

Green Construction is Gaining Momentum in the United States and Abroad

As the practice of green building rises in popularity, construction companies across the United States started to adapt their outdated methods. They reduced their carbon emissions and eliminated waste, improving their sustainability under the pressures of environmental regulations and public attention.

In this transition, construction companies have also embraced the use of green building components. In doing so, they decreased their dependence on harmful materials and increased their investment in eco-friendly alternatives. Naturally, these changes benefit progressive investors looking to build their portfolio.

Of course, you shouldn’t select the first company that has an association with green building. You have to take a strategic approach, choosing the green building stocks that show significant potential. To that end, this article will serve as a resource to guide you in the right direction, providing the top stocks of 2025.

Nothing is a guarantee, of course, and risk is an inherent element in every investment. Even so, you should review these five options for your portfolio. In the coming decade, the interest in “going green” will only continue to grow, and you can take advantage of these trends with the following stocks.

1. Johnson Controls International PLC

Johnson Controls provides a diverse range of tech-driven solutions for building efficiency and similar purposes. With their experience in building-related equipment — and their mission to create “a smart future” for facilities — they represent an excellent option for investors searching for green building stocks.

Concerning the expected earnings, their EPS forecast for this quarter shows $0.63 with a P/E ratio of 32.21. Johnson Controls pays an annual dividend of $1.48 per common share. Their earnings growth last year was +35.78%, and their projected earnings growth over the next five years is +8.50%.

Clearly, Johnson Controls International PLC has significant promise within the context of current trends. Their management technologies will prove valuable to building managers as they improve sustainability in their facilities. Needless to say, energy efficiency will remain relevant well into the next decade.

2. Honeywell International Inc.

Honeywell International Inc. is a multinational conglomerate company and a leader in building climate control. That said, building automation and control represents only around a third of their sales. They also have aerospace, materials and transportation segments beyond their focus on green building.

Concerning the expected earnings, their EPS forecast for this quarter shows $1.86 with a P/E ratio of 23.79. Honeywell International Inc. pays a quarterly dividend of $0.98 per common share. Their earnings growth last year was +319.35%, and their projected earnings growth over the next five years is +7.47%.

As for the value of Honeywell International Inc., climate control is one of the essential elements of green building. Similar to Johnson Controls, the regulation of a building’s interior temperature is an energy-intensive task. Improved technologies from Honeywell will likely prove important for reducing energy usage.

3. Brookfield Infrastructure Partners LP

Similar to Johnson Controls and Honeywell, Brookfield Infrastructure Partners LP has a focus on energy usage. They’ve identified energy efficiency as a crucial driver of long-term growth, and they hope to improve sustainability and combat the escalating threat of climate change through their infrastructure assets.

Concerning the expected earnings, their EPS forecast for this quarter shows $0.36 with a P/E ratio of 38.3. It fell from over 300 when we published this article in 2019, which shows it is likely no longer highly overvalued. BIP pays a quarterly dividend of $0.54 per common share. This is a $0.04 increase in their dividend earnings from what they were paying in 2019 when we first published this article. Their earnings growth last year was +1,263.25%, and their projected earnings growth over the next five years is +9.59%.

As for alternative options in the same area of investment, you have a range of stocks and funds to select from. For example, 40% of the new international micro-cap fund from Brookvine covers relevant areas like green energy, e-commerce, connectivity, health and wellness, data analytics and cybersecurity.

4. PFB Corporation

PFB Corporation manufactures and sells proprietary insulating building products that use expanded polystyrene. The company operates in both Canada and the United States, selling EPS products, structural insulating panels, building systems and similar tools. Their primary focus is on green building.

Concerning the expected earnings, their EPS forecast for this quarter shows $0.70 with a P/E ratio of 5.8. PFB Corporation pays a quarterly dividend of $0.07 per common share. Their earnings growth this year is 168%, and their projected earnings growth over the next year is 17.60%.

In terms of PFB Corporation’s potential, the increasing demand for alternative building materials will likely continue into the next decade. Among other green building materials, it’s safe to speculate that PFB Corporation’s expanded polystyrene and similar eco-friendly insulators will see greater adoption.

5. LSB Industries Inc.

LSB Industries Inc. is a chemical and GHP manufacturer with a stake in green building practices. Around a third of its revenue comes from its climate control technologies, which, as mentioned earlier, represent an essential element of green building in terms of energy efficiency and the reduction of carbon emissions.

Concerning the expected earnings, their EPS forecast for this quarter shows -$0.09 with an unavailable P/E ratio. LSB Industries does not pay a dividend. Though LXU doesn’t appear promising, their earnings growth this year was +153%, and their projected earnings growth over the next five years is +10.00%.

Investors should give thought to LSB Industries Inc. for its present and future relevance to green building practices. Though it may seem somewhat unappealing next to the other options on this list, its earnings growth this year and projections show it’s still an option deserving of consideration.

An Investment in the Future

As you review green building stocks for your portfolio, consider the five companies above. Each has significant potential in 2025 and the next decade, so research these options in greater detail and determine which of them works best for your current goals.

Whether you choose to invest in Johnson Controls, PFB Corporation, LSB Industries or another, similar option, you’ll see that wealth creation and environmental conservation are one and the same.

The post 5 Green Building Stocks to Consider in 2025 appeared first on Green Building Insider.

In a survey reaching over 2,000 international contractors, builders and developers, almost half said they expect to build more than 50% of their projects as a green building by 2022. This figure increased even more this year. The World Banks Blogs published an article in February 2024 showing that the demand for sustainability was growing significantly. World Bank blogger Susan Lund reports that emissions from buildings are expected to drop 23% by 2035 as more organizations invest in eco-friendly buildings.

To protect the environment while cutting down on costs, builders are turning to these seven popular green building practices in 2024.

1. Net-Zero Buildings

Many contractors are aiming to build net-zero buildings, which are buildings whose energy consumption is roughly equal to their energy output. The goal of this type of building project is to cut down on carbon emissions, water consumption and solid waste transported to landfills.

Those with plans to build a net-zero building typically look for ways to generate renewable energy on and off-site. Popular on-site generation tactics include wind turbines, solar water heating and photovoltaics. Off-site options include large-scale wind farms, solar plants, geothermal plants and hydropower facilities.

The credit offered for generating power sustainably will most likely offset the cost of building these renewable energy sites.

Net Zero buildings are more important in 2024 than ever before. In fact, the White House officially published a definition for them back in June for the first time, which helps emphasize why they are so important.

2. Climate Resiliency

With the growing concern over climate change, one of the top green initiatives is incorporating construction measures to withstand extreme weather patterns and natural disasters, typically in the form of improved infrastructure.

While many coastal cities have taken steps to relax their building codes, not strengthen them, developers are still seeking methods to go above and beyond, aiming to build stronger frames and increase weather resiliency to mitigate weather damage and cut down on insurance costs, such as claims for flood or fire damage.

3. Green Star Certification

The Green Star certification globally promotes integrated building designs which reduce environmental impact.

When a contractor goes through the certification process, their building or project receives a rating from an independent panel of sustainability experts. This rating can verify that a building or community project is a sustainable endeavor.

The rating a project receives comes from nine categories, from building design and construction to operation. Each category assesses the sustainability of a project and determines potential optimizations.

4. LEED Certification

Currently, LEED is the most widely used sustainability rating system in the world, certifying 1.85 million square feet of construction each day. Anyone can claim their building is sustainable. However, a LEED certification holds builders accountable through a structured, points-based rating system.

Earning a LEED certification comes along with many essential benefits, such as lending third-party credibility to an organization’s ability to develop a sustainable project. Not only does the certification process offer advice on the use of indoor and outdoor materials, but it also aids in reducing operational costs by encouraging the use of reduced and renewable energy sources.

This type of certification also indicates to the public where an organization’s priorities lie. It demonstrates a commitment to both sustainability and new green initiatives, building goodwill with the community as well as company stakeholders.

The number of LEED buildings is growing significantly in 2024. There are now 111,397 LEED projects and that number will likely grow over the next year.

5. Distributed Energy Systems

A distributed energy system (DES) controls generation, storage and energy monitoring solutions. Through the use of sensors, meters and actuators, the system can oversee and observe a building’s performance — including heating, cooling, lighting and more — as well as offer suggestions for cutting costs and improving reliability.

Many developers have decided to integrate a DES into their sustainable designs to take advantage of the plethora of benefits.

The benefits of a distributed energy system include:

• Reduced operational costs
• Improved energy reliability
• Reduced carbon footprint
• Additional revenue sources

Many developers have also used a DES to implement the electrification of a motor vehicle fleet, lowering costs and increasing uptime with a more reliable charging system.

6. EDGE Certification

EDGE stands for Excellence in Design for Greater Efficiencies, a certification which aims to increase construction efficiency in terms of energy, water, building materials and waste.

Getting started with EDGE is very simple for developers, starting with a downloadable software program which allows them to determine the ideal combination of building strategies for the best return on your investment. Upon completion of a project, whether it’s a home, office, hospital or warehouse, an independent panel of experts will audit it to determine if it meets the required standards.

Currently operating in over 130 countries, EDGE certification requires developers to commit to at least a 20 percent reduction in energy and water use as compared to a standard building.

7. Alternative Building Materials

Building and construction activities consume 3 billion tons of raw material each year globally. But this reliance on non-renewable materials has had a lasting impact on the environment and the number of available resources, meaning developers are looking for alternative materials to build with.

2024 has seen a surge in the number of builders using more sustainable methods, with common alternative materials including the following.

• Grasscrete: A technique of layering concrete flooring in a way that allows grass and flora to grow, creating a natural bio-filter and improving storm-water absorption.
• Bamboo: A cost-effective, quickly growing material that is easy to harvest, making it a sustainable material source.
• Recycled plastic: With a lifespan of 30 to 50 years, plastic is a durable and long-lasting building material.
• Wood: Use of wood absorbs carbon dioxide and requires less energy-intensive processing methods.
• Hempcrete: Made from hemp wood, water and lime, this sustainable material is durable and long-lasting.

Other alternatives to traditional building materials include papercrete, engineered wood, cob, steel frame and insulating concrete foam.

Using Green Building Practices

Green building initiatives are booming in popularity, especially with the threat of dwindling renewable resources and unpredictable climate changes. Green construction initiatives accounted for more than 3.3 million jobs in 2018 in the United States alone. That number rose to 303,500 jobs in 2024.

Industry experts also predict these new trends will heighten global awareness of green development in the years to come, leading to newly developed and more efficient sustainable initiatives.

The post The 7 Most Popular Green Building Practices in 2024 appeared first on Green Building Insider.

These days, one of the most effective and trending ways to go green is to not only look at how we live, but also where we live, and to take those practices, products and policies into our houses. Whether we are making green updates to a treasured home, or building a new eco-friendly house, let’s take a look at how green building impacts our wallets. You don’t need to live in a smart house to be green. There are a lot of other sustainable living ideas to try.

Green Building Certifications

There are many certification programs available for green building that notably increase the value of your property, and often lead to other incentives such as tax breaks and grants. Green certified buildings often even receive discounts on homeowner’s insurance. Leadership in Energy and Environmental Design (LEED) issued by U.S. Green Buildings Council, is probably the most easily recognized sustainable building certification, as more than 1.6 million residential units are currently participating in LEED around the world. Other popular certifications include Energy Star, BREEAM, and Green Globes. Prospective buildings undergo a thorough third-party verification process, including an onsite inspection and performance testing. Successfully certified homes deliver on design plans and meet green building commitments that save energy, water and other resources. But do they save money? By using less energy, green homes also lower utility bills. On average, LEED certified homes save 30% of water and 15-20% of energy, which averages out to about $70 per month in utility bill savings. While the typical cost of an entry level LEED home is about 3 to 5 percent higher than a conventional home, that additional cost is canceled out by utility savings, making a LEED certified home with all of its benefits- from cleaner indoor air quality for the family, to a lower carbon footprint for the planet- comparable in cost to a traditional home meeting minimum building code.

Tax Breaks

We talked about a number of financial benefits of green buildings for both consumers and businesses in the past. One benefit is tax breaks.

Like certifications, there are many available tax breaks, grants, and other financial incentives for green construction, helping many families to make the commitment to saving the planet. Federal, state, and local governments want your home to be more efficient and earth-friendly, and surprisingly, so do many utility companies. From solar to wind, geothermal to fuel cell energies, the tax breaks being offered can make a huge impact on their cost for either new or existing projects, offering up to up to 26% of the installation and equipment as a tax credit. Not to mention all of the state, local and utility deals. For example, Pacific Gas and Electric, a leading California utility company, offers utility bill rebates of up to $120 to customers who purchase efficient appliances and equipment. The building of eco homes is on the rise with thanks going to these tax breaks and money saving incentives. Keep in mind these tax breaks are set through December 31, 2021, when they will be reevaluated.

Uncertified Updates

On the more affordable end for the homeowner who wants to make sustainable upgrades without the commitment of a certificate or a new build, there are tons of options. There are simple best practices that are cost effective and low effort, like sealing windows and other air leaks (90 inches of weather strips costing about $12), taking shorter showers, turning lights off or switching to LED bulbs (8 pack for about $10), and using pressure cookers (ranging from $50-$250) rather than the energy intensive ovens. There are more long-term investments such as installing energy efficient windows or doors (lowering energy bills by 12% on average), installing a whole house fan (saving 90% in cooling energy costs on average), or upgrading kitchen appliances (qualifying for tax breaks plus potential energy bill savings of over $100 per year).

Final Thoughts

It is very clear that energy saving, means energy bill saving. If a family is able to front the cash to make the upgrades or commitments to a sustainable lifestyle, the numbers say they will save money in the long run. Luckily, we don’t have to choose between saving a buck or saving the planet, with options for every person on every budget. Not only that, but government financial incentives make it easier than ever to make the switch to a green lifestyle. It is heartening to know that energy companies, insurance companies, local and federal governments all are on the same page about saving the planet, and want to create the easiest, most accessible path for homeowners to get on board, too.

What does it mean to have a zero-energy building? People can learn the answers to these questions — and more — with this helpful net-zero guide.

What Is a Zero-Energy Building?

Many people want sustainable buildings, which maximize the use of natural resources to minimize the impact on the planet. A net-zero, or zero-energy, building takes that goal to the next level.

A widely accepted definition is that the building is so efficient and reliant on renewable sources that the total energy it needs is equal to or less than the renewable energy produced at the site. Some organizations also call these structures zero-carbon buildings because the total carbon dioxide emissions equal zero or a negative value.

Net-zero homes are still relatively rare in the United States, with about 5,000 single-family houses that produce zero carbon. Some analysts believe the tides are changing, but not all at once.

For example, California now mandates that most new homes and multi-family residences up to three stories high must have solar panels, a step in the right direction in achieving a net-zero goal.

What Are the Benefits of a Zero-Energy Building?

When people think of the advantages of a net-zero building, the energy savings often come to mind first. Eliminating one’s dependence on the electrical grid is also appealing, especially for individuals who are concerned about price fluctuations.

Speaking of the grid, if a zero-energy building produces more energy than necessary, occupants can sell the excess to power companies as an income-generating activity. For example, the Unisphere is one of the largest commercial buildings in the United States. Since its design includes nearly 3,000 solar panels, all surplus power produced during the day gets sold to the grid.

A net-zero building can also be educational and help people feel influential to the future of the planet. Virginia’s Discovery Elementary School, for instance, is a net-zero facility. About 75 of its students take part in the Eco-Action Team, which has monthly meetings to teach young people about how to save energy, live healthily, consume less and other pertinent topics.

Buildings account for around 30% of greenhouse gas emissions globally, and carbon dioxide is one of the most abundant emissions. Therefore, a zero-carbon building trend could mean that structures earn a better reputation by helping the planet instead of hurting it.

Moreover, if a brand commits to reaching a zero-energy milestone by a specified time, it could become a leader for other commercial entities to follow. Fulfilling that role could be crucial if a company’s target audience is especially eco-conscious or the brand has made previous efforts towards sustainability and wants to maximize them.

What Challenges Exist for Net-Zero Buildings?

The quest to erect more net-zero buildings is not without its difficulties. One issue is that some corporations want to get behind a goal of achieving net-zero emissions by 2030 or 2050, but not all of them agree on what net-zero means. The definition given earlier in this guide is a frequently used one, but it still hasn’t achieved universal acceptance.

Relatedly, there is no single method for verifying and certifying greenhouse gas reductions achieved through net-zero emissions. Coming up with one would help companies figure out what they’re doing well and where there’s room for improvement.

People have complained that it’s fine to have net-zero goals, but the aspirations fall apart when companies don’t have a well-defined gameplan for reaching that distant objective. For example, Rio Tinto is a mining company that will make a $1 billion investment over five years to meet climate goals. However, the company’s CEO, Jean-Sébastien Jacques, has said, “There is no clear pathway right now for the world to get net-zero emissions by 2050.”

Another difficulty is the unequal pace of progress in this area across the globe. For example, Ireland has what it deems “nearly net-zero buildings.” These new homes must be 70% more energy-efficient and produce 70% fewer carbon dioxide emissions compared to those built in 2005. Plus, energy analysts point out that net-zero buildings are not priorities for some Asian nations, and people there still see a future that uses coal.

However, if a person or company is genuinely interested in moving ahead with net-zero buildings, they must try to focus on what’s within their power to do. It’s impossible to make every resident or country promise to work towards a particular energy generation or emissions objective. Fortunately, committed people and brands can still make impressive progress through diligent dedication.

What Steps Can People Take Towards Net-Zero Buildings?

If a person is interested in living in a zero-energy home, they must decide what steps they’re willing to take to make that happen. One option is to work with a zero-energy builder who can either create a residence from the ground up or retrofit an existing one. Also, New York has a net-zero apartment complex called netZero Village. It could be a possibility for people who want to move into net-zero homes and are willing to relocate if necessary.

Another necessity is to decide whether the net-zero definition only extends to energy use or goes beyond. For example, some people bring other aspects, such as water and waste, into their zero-energy plans. In that case, a person has what’s sometimes called a net-zero-passive house. A passive house is not necessarily net-zero, but the term refers to making the house have as small of an ecological footprint as possible. As such, net-zero and passivity go together well.

Some local authorities also realize that it’s not feasible to expect commercial entities to meet a net-zero goal right away. In Pittsburgh, Pennsylvania, members of the city council unanimously passed a measure to make all of the area’s new or renovated government buildings net-zero ready.

In essence, that means they’ll meet a standard that enables using very little energy. Then, over a year, that usage is offset via a connection to an on-site or local energy source. Such an approach shows that city officials aren’t trying to do everything at once, but they’re laying the groundwork for meaningful, timely improvements.

Even if people are not at the point where they’re directly associated with net-zero buildings, they can still show their support for them. In September 2020, London will be the site for the world’s first Net Zero Festival, a gathering that brings people from various sectors together to explore how to achieve some of the energy goals set around the globe. Planning to attend could help interested persons stay in the loop about building practices and more.

What Is the Future for Zero-Energy Buildings?

As mentioned earlier, numerous nations have net-zero goals. However, they aren’t only focusing on buildings. In Serbia, a music festival’s campaign ultimately convinced the government there to plant one billion trees as part of a broader effort to reach zero carbon emissions by 2050. The structures that people live and work in will undoubtedly play key roles in the overall aims, too.

An industry analysis anticipates a 15.6% combined annual growth rate for net-zero-energy buildings around the world from 2019 to 2024. Several areas in Europe may become zero-energy districts, too.

A Net-Zero Building Is a Worthy Aspiration

It’s not realistic to expect the world to make a quick transition to zero-energy buildings. However, the examples here show that the idea is taking off globally.

Since many countries have set goals to reduce emissions, leaders will need to assess how buildings fit into their respective targets. Making a net-zero building requires extensive planning, but following through could have positive effects for this generation and future ones.

Sustainability is often integrated into CSR aims. Companies frequently pledge to track and reduce the resources they use or require their freight partners to gradually transition to new practices that reduce CO2 emissions.

Another practical and effective option is to investigate the possibilities of sustainable infrastructure. Let’s examine how such buildings support broader CSR goals.

Sustainable Certifications Are Popular Options

When companies assess how sustainable infrastructure fits into their CSR goals, they often pursue Leadership in Energy and Environmental Design (LEED) certifications. Several levels of LEED certification exist, and an organization receives points according to the measures they take to become more sustainable. Points get awarded in six main categories, including water efficiency and site selection.

In the summer of 2019, news broke that the organization that developed the Olympic House, which serves as the headquarters for the International Olympic Committee, received the most points of any new LEED-certified construction project up to that time. It received 93 LEED points and is the first building in Switzerland to earn LEED v4 certification.

Moreover, It’s the first international headquarters building to get the Swiss Sustainable Construction Standard (SNBS). The certifications reportedly tie into the 2020 Olympic Agenda which, is one of the three “pillars” of the upcoming competition.

Another option is for companies to set their sights on ISO 14001:2015 – Certification for the Environment. It’s for companies in all industries and helps them protect the environment, prevent pollution and improve their environmental performance. A focus on continual improvement makes this option like other ISO standards, although this one centers on environmental aspects and how they affect a business.

Earning a certification is not the only way for an organization to focus on sustainable infrastructure, of course. However, when companies or groups strive towards recognizable achievements like the ones described above, it’s easier for the public and peers alike to understand what certification means, and why it’s such an accomplishment.

A Sustainable Building Could Include a Green Roof

Green roofs feature grass, vegetable gardens on what’s typically a building’s highest surface. Evidence suggests these roofs can cut energy costs, minimize flood damage, provide habitats for wildlife, beautify buildings and more. Despite these benefits, green roofs have not yet reached the mainstream everywhere.

A well-designed green roof must distribute and store water for the plants it holds. It’s typically easier to integrate such infrastructure into the roofs of newer buildings compared to older ones. That’s one reason why North American cities, where the buildings are not as old as those in many European cities, have roofs with green buildings more often.

Plus, green roofs tend to appear in places where local legislators embrace the benefits of such infrastructure and agree to adjust budgets to support them. Once leaders give nods of approval, building professionals should find they don’t encounter as many challenges when meeting the needs of their clients who say they want green roofs on their buildings.

You can probably imagine how a green-roofed building could help employees feel more connected as they spend some of their free time to collectively nurture the plants growing in these gardens. But some businesses have a further-reaching mindset concerning how a green roof relates to CSR. Remember, a corporate sustainability plan examines how to improve society. That frequently means feeding communities.

Boston Medical Center boasts a 2,658-square-foot farm on its roof. Although health care facilities treat ailments, they also take preventative approaches to help people stay healthy. Often, that means encouraging them to eat nutritious diets. What if patients have difficulty accessing the food required for a health-promoting diet? The hospital runs the Preventative Food Pantry, giving participants access to dozens of crops to feed their families.

Green Buildings Are Gaining Popularity

We’ve covered some of the possibilities for companies to pursue if they want to make green buildings part of their corporate sustainability goals. However, other options are particularly easy to install and start reaping the benefits. Some businesses may wish to explore those first before concluding that they want to substantially revamp their infrastructure to make it more sustainable.

For example, a company may install new faucets in its restrooms that use less water and turn off automatically once a person leaves. Those solutions could avoid waste. Similarly, motion sensors could help ensure that no one accidentally leaves their office light on when going home. Smart thermostats are also widely used, and they assist a company in keeping its internal spaces comfortable without excessive energy usage.

Regardless of the specific ways a business decides to take advantage of sustainable buildings, a recent market research report indicates the green building market is poised for growth. It estimates a 10.26% combined annual growth rate for the sector from 2018-2023. That finding suggests that it’s time for construction professionals to update their knowledge about green infrastructure to prepare to meet clients’ CSR aspirations.

A Trend Worth Following

A comprehensive CSR plan encompasses a variety of aspects that a company deems essential. This overview shows that businesses can — and should — investigate ways to strategically include sustainable buildings in their intentions to give back and help societies via their resources and actions.

More homeowners and renters want sustainable abodes, and business owners desire increased revenue from energy-saving buildings. Building certifications such as LEED, BREEAM and Green Globes grow in recognition as contractors dive into sustainability head-first. The construction industry is listening to the public’s concerns, and they’re rapidly adapting to address these points.

The energy-intensive materials of yesteryear have faded in favor among environmentalists, and the general public is following. Attractive and sustainable solutions swoop in to replace them. Though many ideas exist — some current and some old — the construction industry favors a few in particular. Here is a list of seven sustainable building materials construction companies often use.

1. Bamboo

Bamboo resists pests and disease, making it a stress-free option for building owners — no termites means fewer bills to pay. It’s more durable than concrete, providing a sturdy structure for frames and walls. Bamboo’s lightweight quality makes foreign transportation less fuel-intensive, although there are a few species native to North America. It also grows quickly, which allows for abundant harvesting — some types shoot up to three feet within 24 hours.

Green buildings often feature bamboo in flooring, walls and cabinets. In locations with limited access to steel, builders use it to reinforce concrete slabs, adding an extra layer of strength.

2. Reclaimed Wood

Rustic chic enthusiasts, this one is for you. Building with reclaimed wood involves reusing preexisting wood and restructuring it for a new purpose. If you’ve been to a vintage store, you’ve seen plenty of dressers and chests made of this material. Contractors find it equally convenient for construction projects, as it provides durability along with charm and low cost.

Reclaimed wood possesses a lower embodied energy than fresh wood because it doesn’t undergo the cutting and curing process. A percentage of lumber is always lost during cutting, but this can go towards creating engineered wood. Reclaimed wood also decreases deforestation and allows trees to grow to proper maturity before their eventual harvest.

You’ll most often find reclaimed wood in support beams, countertops, shelving and flooring.

3. Precast Concrete

Precast concrete slabs are recyclable — construction workers make them with locally mined or recycled materials. Their production requires less energy than pouring concrete on-site, and they offer fewer chances for structural cracks and errors. These slabs arrive at construction sites according to predetermined specifications, which saves a tremendous amount of time and energy. Efficiency is a requirement at many construction sites, and precast concrete fits the bill.

The strength of concrete slabs functions well in constructing bridges, underground infrastructure and pavement. Along with its toughness and fire resistance, it also absorbs sound, making it ideal for places like libraries and hospitals.

4. Cork

Now you can have the perfect home aesthetic to match your wine collection — who would’ve thought? Construction companies commonly use cork as a flooring solution, though it also works as insulation. It’s fire-resistant, impenetrable and liquid-proof, which saves the hassle of constant upkeep. It also has excellent thermal and acoustic absorption, making it for great blocking out sound and holding in heat.

Cork grows on trees that regenerate their bark, which leaves them healthy and ready for the next harvest. These trees primarily exist in the Mediterranean, which can make fossil fuel emissions higher. It makes up for this with its lightness, though, by reducing the energy needed for transport.

5. Steel

Metal is one of the most durable building materials of them all. You see it in towering skyscrapers, winding railroad tracks and sturdy bridges every day. The possibilities of this material are endless, and luckily, steel doesn’t require a ton of energy to produce. The carbon footprint of steelmaking has decreased by 37% since 1990, and engineers continually find ways to streamline the process.

Once a metal structure reaches the end of its purpose, builders can deconstruct it and recycle it for new initiatives. Steel is unique in its ability to be reused forever. Ninety-three percent of structural steel in the U.S. consists of recycled metal, which proves how versatile this material is.

6. Non-VOC Paint

Many paints and varnishes contain chemicals called volatile organic compounds, or VOCs. These are irritating at best and deadly at worst, and their concentration rises indoors. Before you give up your painting hobby for good, though, know that non-VOC paints exist. Developers are starting to use these inside green buildings instead of toxic paints. You’ll also find an abundance of low-VOC varnishes at your local department stores, but this label can be ambiguous. How much is “low” without a specific number?

Using non-toxic paint can even reduce the need to run the AC to cycle chemicals out of the air, which saves money and energy.

7. Wool

Sheep’s wool serves as a common substitute for more toxic insulation types. It grows faster than cotton — meaning higher production — and it doesn’t degrade like straw does. The most sustainable manufacturing processes come from New Zealand. Water efficiency, flock health and energy conservation are paramount on New Zealand sheep farms. The nation’s care and attention to detail has secured their position as a giant in the wool making industry.

Head to the nearest home goods store, and you’ll likely find a wool rug or two. It’s become a favorable solution for rugs and carpeting due to its ability to purify indoor air. Wool absorbs nasty particles and contaminants and prevents them from reentering the atmosphere, leaving you with cleaner oxygen.

Constructing Greener Futures Through Innovation

Green building materials prove their durability and efficiency in countless ways. More construction companies and consumers will reap the benefits of sustainable building as businesses make the switch. Soon, it’ll be commonplace to uphold eco-friendly initiatives in the comfort of your home.

The post 7 Most Popular Green Building Materials appeared first on Green Building Insider.

This focus on creating green buildings is admirable and necessary. However, construction professionals can’t afford to prioritize the planet over the safety of occupants. Safety and sustainability can go together, but only if builders pay attention to both of these elements at the design stage.

Sustainability and Fire Safety

Fire safety is a top concern for today’s builders. Most countries have fire safety inspectors who ensure that all buildings meet the minimum requirements for fire safety. But even when a building’s materials don’t violate any laws, they can still pose a risk to firefighters.

Researchers from Worchester Polytechnic Institute received a $1 million grant to continue earlier research that showed the potential hazards of some green materials.

For example, lightweight engineered lumber uses fewer materials than conventional lumber, and many professionals view it as an eco-friendly option. However, the material is also more likely to collapse during a fire if it’s part of the flooring. Researchers also brought up the potential for electrocution by solar panels.

Solar panels make things difficult for firefighters because they often have independent power sources. That may mean that cutting off the main power for a burning home doesn’t eliminate the risk of active electricity associated with solar panels. Moreover, the location of solar panels may prevent fire crews from cutting holes in a roof to help smoke escape.

Some eco-friendly buildings also have a minimalist design to reduce waste. It may look chic and inspire occupants to do more with less, but the simplified design might not have as many barriers in place to contain fires.

For example, many apartments, hotels and hostels in the United Kingdom have fire doors in communal areas such as corridors. The goal of a fire door is to keep flames in a smaller area rather than letting them spread to places where they endanger more occupants. People who aren’t familiar with these designs might think it’s wasteful to have so many doors, but they don’t realize that they ultimately promote fire safety.

Ensuring a Safe Water Supply

Construction professionals need to ensure their structure meets fire safety standards, but that isn’t their only responsibility. They also need to equip their building with basic conveniences like running water. To that end, it’s crucial to keep health concerns in mind, such as preventing Legionella pneumophila outbreaks. Legionella is a type of water-borne bacteria that can live in things like decorative fountains or showerheads.

According to research, up to 70% of buildings in the U.S. that are taller than three stories may have Legionella issues. Also, scientists at Purdue University found that low-flow plumbing systems could promote the multiplication of dangerous pathogens, including Legionella pneumophila.

Part of the problem is that the flow rates have gone down while the diameter of plumbing pipes have stayed the same. That means that water can age in the pipes, making it potentially contaminated by the time it reaches a consumer. This information will aid builders and other decision-makers in using low-flow systems to reduce the risks.

If building designers want to address an occupant’s need for clean, fresh water while also being eco-friendly, they might consider adding something to a public area of a building, such as the lobby. Dasani is testing a water dispenser that gives still or seltzer water to people who bring bottles to fill. It’s one of many strategies the brand is using to address the issue of plastic waste.

Uncertain Effects of New Materials

Designing a fire-safe building involves many aspects that people can see, such as the number of exits. But protecting a building from a future fire also requires retardant materials. For example, there are special bricks containing fire-retardant materials, and some of the fabrics or fillings used to make couch cushions also have those same characteristics.

Research has shown that some flame-retardant materials have an adverse effect on the environment. So engineers came up with “better” alternatives. However, a recent study from the American Chemical Society suggests that the newer option also has a negative impact.

More specifically, a supposedly superior option called “polymeric flame retardant” is less likely to enter biological cells or the food chain. Unfortunately, researchers found that it can break down into harmful compounds after exposure to excessive heat or ultraviolet light. The team clarified that this could present issues if using the material to insulate a hot attic or when discarding the material at a landfill.

This finding illuminates a larger challenge as well: It’s often impossible to know the long-term effects of newer products.

For example, scientists have made substantial headway in creating eco-friendly plastics, a positive development considering how dependent modern society is on the material. But is it possible that these new plastics could introduce hazards as they age? Absolutely. The trouble is that people can usually only speculate until the newest options reach the point of mainstream, long-term use.

Worker Safety and Green Buildings

Construction work can be dangerous, even if laborers have the necessary training and follow appropriate procedures. That said, research has shown that green construction can be especially hazardous. A study from 2012 focused on several case studies associated with LEED-certified buildings. It found that people on those projects worked near electrical currents, at heights and near unstable soil more often than people working on non-LEED jobs.

Then, a 2018 study collected data from 30 construction companies in Singapore. It found a higher accident rate for green building projects versus conventional ones. There are undoubtedly many variables at play that may cause a rise in safety risks. Since some green building materials and techniques are relatively new, people don’t have adequate experience working with them.

Another possible issue could be the limited time frames in which construction workers have to complete green building projects. Tight schedule requirements stem from both the increased interest in green building projects and the frequent instances of governments setting net-zero emissions targets by particular deadlines.

If construction company owners and project managers are too focused on profit, or they feel pressure from deadlines, some of them may sacrifice safety. Even if sustainable buildings reach completion under budget and on schedule, worker safety could still be at risk.

Making adequate training mandatory and setting manageable timelines for sustainable projects could both keep a project safer while still meeting the demand for eco-friendly buildings. Companies should also try to specifically hire people who have ample experience with green building practices.

Safety Is Just as Important as Sustainability

A growing number of people recognize the need for green buildings. It’s important, of course, but it’s equally essential to keep builders and occupants safe and secure.

The post The Intersection (And Challenges) of Green Buildings and Safety appeared first on Green Building Insider.

This guide answers five common questions about those structures for anyone who wants to learn more about net-zero-buildings and perhaps even live in one.

What Is a Net-Zero Building?

A net-zero building produces as much renewable energy on-site or in the surrounding area as it consumes yearly. Its design and materials are ultra-efficient, which also means it relies on the grid substantially less than conventional buildings do.

How Do Net-Zero Buildings Impact the Environment?

Net-zero buildings have both obvious and less-evident benefits for the environment. First, they depend less on electricity from the grid, which often requires fossil fuels.

However, research indicates that net-zero buildings can help modernize the grid and even aid the structures that don’t primarily rely on renewable energy. When net-zero buildings produce more energy than necessary, the surplus is fed into the grid, ultimately supplying power to those who need it. Over time, that effect could make the demand and use of fossil fuels go down as people choose renewable energy more often.

Net-zero buildings can also help scientists evaluate the worthiness of techniques to increase energy efficiency in all kinds of homes and office buildings. Consider, for example, the results of a net-zero test residence operated by the National Institute of Standards and Technology (NIST).

By making small alterations to the building’s climate control and ventilation systems during the home’s second year of operation, researchers quadrupled the amount of surplus energy sent to the grid in one year. This excess energy equals about 1,000 gallons of oil or more than 7 tons of coal.

Buildings account for 39% of the CO2 emissions from fossil fuels and consume 70% of the electricity load. As such, there is an ongoing push to figure out how to make buildings less responsible for CO2 emissions. The NIST model is a residential home, but once people see what’s possible with the technology it uses, they may become more enthusiastic about developing net-zero structures in the residential and commercial sectors alike.

What Non-Environmental Advantages Could People Anticipate With Net-Zero Buildings?

Most benefits cited about net-zero buildings mention the environment. However, other associated perks don’t directly link to the planet. For example, net-zero buildings have predictable operating expenses to a larger degree than conventional ones do. Thus, the people who build them are potentially not as impacted by fluctuations in electricity, oil and natural gas, which could give them more financial stability.

Moreover, a Harvard study found a connection between green buildings and better cognitive function. The researchers did not focus on net-zero buildings, specifically. But, their findings could prove significant to managers and other executives that want to look at creative ways to boost productivity and well-being.

Tax breaks are also available, and people who decide to build net-zero homes or upgrade their abodes to be more energy efficient could qualify for them. The specifics grant a tax credit of 30% for people who install renewable energy equipment such as solar panels. Similarly, if people perform other energy-efficient upgrades not related to renewable energy, they could get up to $500 through a separate credit.

These examples show that net-zero homes pay off in other ways besides helping the environment. Such advantages make them appealing for people to consider even if their priorities span beyond environmental sustainability.

How Do Net-Zero Buildings Factor Into Broader Climate Change Mitigation Aims?

When people talk about net-zero buildings, they often think of the impact those structures will have on their personal lives and in their communities. But, they may stop short of thinking about how net-zero buildings fit into the climate goals of countries around the world. Scientists warn that there is only a 12-year window in which to mitigate climate change and prevent catastrophes. Net-zero buildings could help.

In some cases, making progress requires retrofitting buildings to meet net-zero goals. When Colorado’s McWhinney real estate did such with 10 of its properties, the results caused expected 10-year cost savings of $3.6 million. Also, a research team at Northumbria University says the global value of real estate is $217 trillion — and if owners don’t act now, upcoming climate change mitigation measures will make non-energy efficient buildings obsolete.

The United Kingdom set a goal of achieving net-zero emissions by 2030. Politicians responded by asserting how building upgrades must become a national priority there. They pointed out that it’s impossible to think realistically about meeting any climate change goals without taking buildings into account.

Other nations must also recognize that reaching future emissions targets requires taking an all-encompassing look at where and how to make improvements. Those in charge often agree that building efficiency aligns with overall climate goals.

How Could Net-Zero Buildings Empower Future Generations to Make Positive Changes?

Many of the discussions surrounding climate change and the planet center on the need to teach today’s younger generations how to live sustainably. Today’s older adults typically didn’t learn about climate change awareness in school because scientists didn’t yet know the severity of the issue. It’s undeniable now, and forward-thinking educational representatives could use net-zero schools as teaching aids.

Net-zero school construction has increased by 850% across the U.S. and Canada since 2010. The energy footprint of one net-zero elementary school in New York was 52% smaller than a traditional school a year after it opened.

More recently, the National University of Singapore opened a six-story net-zero building in January 2019. The facility’s roof features more than 1,200 solar panels that should generate about 500 megawatts of electricity each year. The learning institution keeps a daily account of the amount of energy generated versus supplied by the grid. Efforts are also underway to help students adapt to new habits that could reduce energy demand by up to 60%.

Students who learn in net-zero buildings could come away with tips and techniques to apply to their daily activities for life. Of course, teachers can quote statistics from textbooks or take students through interactive lessons that discuss how climate change and environmental sustainability affect their lives. But, net-zero buildings enable scholars to view learned concepts in action.

Net-Zero Buildings Could Lead the Way Into the Future

This detailed overview of why net-zero buildings make sense for the needs of the planet and society should give people food for thought as they investigate how to live responsibly.

Living in a net-zero home or working in a net-zero complex doesn’t necessarily mean constructing something from scratch first. Retrofitting options are available, which may be more feasible for some organizations or individuals.

Here are some of the benefits you might not know about:

Cost Savings

An aspect of green building that you may not have considered is the financial benefit. While the up-front costs of building green are often greater than the standard non-sustainable materials, the long-term benefits far outweigh these costs.

For example, LEED-certified buildings can cut utility costs by around 25 percent, while lessening water usage in green building is lessened by 11 percent. With these savings, you will have already recouped any additional building costs over time. The addition of energy-efficient windows is said to have a return on their investment by over 20 percent. On top of that, there are tax incentives for those who are building green, making this commitment to green construction even more of a no brainer.

Furthermore, likely the best financial reason to invest in green building is market demand. Green projects up the value of your property, and those looking to buy are often consciously seeking homes and offices that follow environmental standards. If you ever want to sell your property, green certification will be a compelling selling point, certainly, but moreover, conscientious buyers are turned off by properties that have not considered sustainability in their construction.

Human Benefits

You may have considered these financial rewards of green energy, but perhaps a set of benefits that you did not anticipate is that green building has an immediate positive impact on the physical and emotional health of residents.

Lowered Stress

Imagine if something about the place you live could improve your marriage, or make family time better. Research has shown that living in a green building lowers stress level. Building features such as more ambient light or improved indoor air quality can lead to a reduction in seasonal depression and a boost in mood and morale.

Decision-Making Skill

Once you’ve already made the choice to build green, you might not know that this decision might allow you to make more decisions. A Harvard School of Health study showed that those that resided in a green building had an over 40% better track record when it came to making good decisions. If you’re working from your green home or working in a LEED building, you can experience better productivity as well.

Research demonstrates that those working in green environments are over 15% more productive. In addition, a COGfx study found that people who worked in greener spaces were 130% better at planning and strategizing during a crisis. With that in mind, your green home may just improve your ability to act under pressure.

Improved Health

If you live in an urban area, you might not imagine that the inside of your house can be more polluted than the outdoors, filled with car exhaust and factory smoke. However, studies show that poor indoor air quality causes all kinds of sickness. There’s even a condition called Sick Building syndrome which shows that when an area is not well ventilated it can easily become riddled with contaminants. Green buildings can improve airflow and air quality, reducing sick building syndrome by 30 percent.

Better Perceptions

In addition to creating calm and being good for your health outcomes, green buildings have been shown to have a positive effect when it comes to an emotional connection to the place where people reside.

One piece of research showed that people were over 15% more likely to feel a general sense of well-being, in addition to being more cheerful and happier to associate themselves with their surroundings. This led also to a sense of pride in their environment, and a desire to stay and share with others, which translates to a better home and workplace environment.

There are so many reasons to go green when building a home, but the one that might be most compelling is the direct emotional and physical effect on occupants of the building. Green initiatives will not only allow you to contribute to the environment and put money back into your pocket but also lead to improved well-being and state of mind. And you certainly can’t put a price tag on that.

The post Sustainable Buildings Provide Multi-faceted Benefits to Business Owners appeared first on Green Building Insider.

There are several LEED certification frameworks, and each has been developed for the needs of a different type of project:

• BD+C: Building design and construction
• O+M: Building operations and maintenance
• ID+C: Interior design and construction
• Homes
• ND: Neighborhood development

LEED certification is based on a series of credits that each award a specified number of points. In the case of new constructions and major renovations, the maximum possible score is 110. Building projects must have a score of at least 40 to be certified, and there are also three higher tiers: Silver (50+), Gold (60+) and Platinum (80+).

It is important to note that some LEED credits are mandatory for certification. A building that misses even one of the mandatory credits becomes ineligible, regardless of the score obtained.

How a LEED Score is Broken Down

As mentioned above, not all LEED credits have the same weight towards a building certification. For example, up to 6 points can be claimed for water use reduction, but there are 18 points available for energy performance. Project developers can aim for any combination of credits to certify a building, as long as the mandatory items are covered.

LEED credits are classified into eight categories, which add up 109 points. An additional point can be claimed by following an integrative process from the start of the project, bringing the maximum score to 110. The eight LEED categories and their possible points are the following:

• Location and transportation – 16
• Sustainable sites – 10
• Water efficiency – 11
• Energy and atmosphere – 33
• Materials and resources – 13
• Indoor environmental quality – 16
• Innovation – 6
• Regional priority – 4

The first six categories are equal for all projects, with a predefined list of credits. The 16 points under Location and Transportation can be earned automatically by selecting a site that is already certified under LEED for Neighborhood Development.

The innovation category grants up to 5 points for measures that reduce the impact of a building and are not covered in other categories. As their name implies, regional priority credits are based on geographic location. They cover measures that offer a particularly high benefit under local conditions.

Considering the wide range of technical areas covered, LEED certification requires a multidisciplinary effort. GBCI manages the application process for a LEED certified building, reviewing the credits for which the building is applying. Credits are awarded or denied based on the information provided, and additional information may be requested by GBCI to complete the certification process.

The Importance of Required Credits in LEED Certification

Required credits do not have a score attached to them, but they are mandatory for a LEED certified building. Note that required credits are independent from the LEED score: even if a building project earns more than 80 points, it cannot get a Platinum certification if any of the required credits was missed.

The following credits are mandatory for LEED certification in new construction and major renovations:

Depending on the type of project, additional credits may also be mandatory. For example, schools must meet all the credits in the table above, as well as an Environmental Site Assessment (Sustainable Sites) and Minimum Acoustic Performance (Indoor Environmental Quality).

When getting a LEED certification for a building, a recommended practice is aiming for a number of credits that leaves a margin of error. For example, if a developer plans for a LEED Gold certification, the project should aim well above 60 credits. That way, some credits can be rejected without bringing the project to a lower certification category.

Construction administration is also vital when a developer is working towards a LEED certification. LEED credits cover not only the finished building, but also its construction process. Even if the finished building consumes minimal amounts of water and energy, the LEED certification may be denied if the construction process was very polluting, or lacking in waste management practices.

Does a LEED Certification Offer Competitive Advantages?

Since an LEED certification demands a minimum performance level in water and energy use, the building owner can expect lower operating costs throughout the service life of the property. However, the certification also provides business benefits for developers who have tenant spaces for rent, especially in competitive markets like New York City and Chicago.

If a potential tenant is considering several spaces for rent, the LEED certification level of a building can be an important factor in the decision. Considering that the program has global recognition, using commercial spaces with a LEED certification can boost corporate image. Since the certification covers water conservation, energy efficiency and indoor environmental quality, it is associated with reduced utility bills and a human-friendly working environment.

LEED for Building Professionals

The LEED program not only offers building certification, but also professional credentials:

• The entry-level credential is called LEED Green Associate, and it requires a specified number of training hours and passing an exam.
• Professionals with advanced knowledge on green buildings can apply for the LEED Accredited Professional credential, and there is a version of LEED AP for each of the five frameworks listed above.
• Finally, a LEED Fellow is a LEED AP with an exceptional track record in the green building industry. There is no application procedure – LEED Fellows are nominated.

Although a building can be certified without a LEED AP, the process is much simpler when one of the team members has advanced knowledge on the topic. In fact, the building project earns one point in the Innovation category for having a LEED AP as a team member with a principal role.
