The future of Eco building is modular

As the planet’s population is growing at a rate of over 1% per year, the toll on the environment has been significant. While people are talking about plastic pollution, ozone depletion, and greenhouse gas emissions, hardly everyone understands the substantial impact of traditional construction methods and benefits offered by modular construction.

According to the Environmental Protection Agency (EPA), 569 million tons of C&D debris were generated in the United States in 2017. Other resources suggest that construction is responsible for 23% of air pollution and 40% of the drinking water pollution.

Construction companies from all over the world are struggling to reduce their impact on the environment. One of the most effective methods is using modular construction.

Less Waste, More Output

One of the biggest problems that traditional construction companies face is waste. The rough estimation is that about 30% of the total weight of building materials is wasted at the construction site.

The basic concept behind modular construction (creating building modules off-site and then assembling them on-site) lowers the amount of generated waste tremendously. According to a study done by the Waste & Resources Action Program (WRAP), off-site construction can reduce waste to 1.8%.

For example, a small 25,000 square foot office building produces about 100,000 pounds of waste. If modular construction is used, the amount can be reduced to about 1,800 pounds. The difference is impressive.

Higher Potential for Recycling

Traditionally constructed buildings generate a substantial amount of waste during demolition. According to the EPA, demolition makes up more than 90% of the total construction and development debris generation.

Modular construction offers a possibility of creating relocatable buildings, thus eliminating the need for demolition when they are no longer needed. Meanwhile, permanent modular buildings have a higher potential for recycling as well. They can be reworked for future projects.

Less Noise Pollution

Since the majority of modular building construction is done offsite in controlled factory environments, noise pollution is minimal.

Excessive noise produced at construction sites isn’t just annoying and frustrating, it can lead to hearing loss, blood pressure spikes, sleep problems, and extreme stress, not only for on-site workers but neighbors as well. That’s why modular construction is highly beneficial for hospitals, schools, and offices.

Less Energy Waste

Since the time spent on-site with modular construction compared to conventional methods is minimized, so is the energy waste. Construction workers spend less time and energy by doing their job in an unchanged setting without any traditional construction site distractions, such as noise or weather. Accordingly, their productivity goes up considerably.

Additionally, constructing modules in a factory-like setting requires the design to be completed in advance. As a result, fewer change orders are entered during the construction process, thus saving time, money, and energy.

Since modular construction doesn’t need as much space as conventional construction methods, the adjustments to the surrounding infrastructure are minimal. Accordingly, the process requires less energy.

As a bonus, it’s easy to incorporate such energy-efficient options into modules as occupancy sensors for lights, energy-efficient windows, solar panels, and high-efficiency HVAC systems.

Better Construction Quality

Since modular construction is performed in a controlled factory environment, many mistakes can be avoided. One of the biggest integrity hazards in construction is moisture. Using dry materials inside the factory can prevent moisture entrapment, thus saving energy and reducing material waste.

Fewer Transportation Emissions

With heavy machinery and multiple workers going back and forth to the construction site, the transportation emissions for conventional construction are high.

Since with modular construction, the majority of work is done within a factory, the amount of on-site emissions goes down substantially.

Eco-Friendly Materials

Many modular construction companies focus on using eco-friendly building materials, lowering the environmental impact while reducing waste production. In addition, many other companies have become adept at reusing existing materials, such as freight and shipping containers, to create new buildings, further reducing material waste.

Even though the entire construction industry is trying to reduce its impact on the environment, traditional construction methods are having a tough time competing with modular construction. Its ability to cut waste, offer better construction quality, lower transportation emissions, and reduce noise pollution is virtually unbeatable.
