That said, the process of construction itself is still rather harmful to the environment. The construction industry accounts for 36% of global energy usage and 39% of energy-related carbon emissions annually, according to the United Nations. 

Modular construction, an alternative to traditional building techniques, offers a possible remedy through efficient processes and shorter project timelines. Overall, modular construction—while not a perfect solution—is a marked improvement in the environmental sustainability of the construction industry.

Read on to learn how modular construction works and how it benefits the environment. 

How Modular Construction Works

Traditional buildings are built directly on site, but modular buildings are mostly constructed in factories and later assembled on the building site. 

Using an assembly line process, workers and machines build modules—which are small, cube-like portions of a building—including the walls, floors, roofs, insulation, and windows. Often, fixtures and finishes are also adding to the modules at this point, eliminating the need to add these later at the building site. 

By the time a modular building leaves the factory, it is already “built” and only needs to be assembled. On the building site, construction workers use cranes and other equipment to hoist each module into place. After each module is set down, workers “lock” the modules together to form a seamless building, then tradespeople connect pipes and wires that were already pre-installed in the factory. 

One notable advantage of modular construction is that projects are completed on average twice as fast. This increase in efficiency is easy to understand: Whereas on a normal building site, construction can’t start until the building site is prepared, a modular building is constructed in the factory at the same time the building site is being prepared. 

Once a modular building is completed, it is indistinguishable from a similar structure built in a more traditional way and often has numerous environmental advantages that traditional buildings cannot compete with. 

Environmental Benefits of Modular Construction

While everyone can appreciate the increased efficiency brought on by modular construction, it turns out that this efficiency is also hugely beneficial to the environment. 

For example, a modular building company that is constructing a number of different structures in its factory is able to reuse materials on multiple projects that would typically end up as debris on a traditional building site. This is very consequential, as the construction industry accounts for 56 million tons of waste every year. The sharp reduction in materials waste encouraged by modular construction methods has huge downstream effects for the environment. 

Because a modular factory is able to optimize deliveries for multiple projects to a central location, modular construction requires 90% fewer deliveries overall, leading to an enormous drop in carbon emissions from trucks and other commercial vehicles. 

Most importantly, the very fact that modular construction projects are more efficient is beneficial to the environment, since it involves lower energy expenditures. The factory optimizes its processes through machine learning, reducing energy needs, and the construction site has lower energy demands because the on-site timeline is so short. 

Beyond the construction process, many modular buildings have green features embedded, like solar panels, superior insulation, and recycled materials. All of these choices are an extension of the overall environmentally-friendly approach pursued by modular construction companies. 

Examples of Modular Construction

Modular construction is taking off in popularity, though it still only accounts for a small percentage of the $1 trillion U.S. construction industry. Nonetheless, examples of modular construction abound in both residential and commercial construction—with more buildings likely to pop up in the coming years, since modular construction can easily take place with smaller crews, a necessity during the pandemic.

Some modular buildings are created as fanciful experiments in sustainability. For instance, the Wikkelhouse is a small structure from the Netherlands made entirely from recycled cardboard. Despite its curious choice of material, the Wikkelhouse is hardy, expected to last upwards of fifty years. 

While this is a shorter lifespan than a typical house, a basic Wikkelhouse module costs just $35,000. Still, the Wikkelhouse is more of an exercise in creativity and clever use of materials rather than a practical solution to the need for green buildings. 

Others are taking the concept much further with the hopes of completely transforming the building landscape in favor of sustainable production and design. For example, Plant Prefab has recently raised $6.7 million with the mission of revolutionizing the housing market in favor of environmental building. 

Plant Prefab’s ethos revolves around their “Z6 Environmental Program,” which leverages the power of modular building techniques to meet six goals: 

• Zero Energy: Reduce each home’s energy demands with insulation, window treatments, low-energy appliances, and more.
• Zero Water: Integrate low-flow appliances and greywater systems to use wastewater for landscaping irrigation.
• Zero Emissions: Improve indoor air quality by eliminating dangerous chemical compounds from building materials
• Zero Waste: The modular building process eliminates waste by enabling the possibility of reusing materials across projects.
• Zero Carbon: Carbon offsets are purchased to account for all emissions made during building.
• Zero Ignorance: Make sure that homeowners are aware of the environmental impact of their choices.

While these goals are articulated clearly by Plant Prefab, they are not unique to that company. Across the industry, modular construction companies are committed to using their technological advancements for the betterment of our environment. The unique process of modular construction is creating the possibility for a revolution in housing that is vital in our current circumstances.

And modular construction is not limited to small projects. Entire apartment complexes have sprung up with modular building techniques. For example, the 1775 Federal Apartments in Denver were designed and built by a modular construction company, and the bulk of assembly took only a few weeks with a crew of just five men. 

Modular buildings also serve purposes beyond housing. An excellent example is High Tech High in Chula Vista, CA, an entirely modular high school that was completed in 18 months, now serving 600 students. 

The project focused on sustainability from the start with incredible results. For example, the modules were built with sloped roofs to align solar panels more effectively, and as a result, the panels produce 85% of the school’s required energy. Water systems were designed to reduce usage, so the building uses 52% less water than a building of comparable size. The contractor used locally-sourced, sustainable materials for construction, and 83% of materials were diverted from the landfill to be used in other projects. 

A well-designed modular project has environmental benefits throughout the entire life of a project, from the construction process all the way through the lifespan of a building. With a climate crisis looming, modular construction may be an effective approach to meeting housing needs while still remaining good stewards of our planet.

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.
