Dear EarthTalk:

What is automated modular construction and how is it greener than conventional building methods?

Gordon G., New York, NY

Automated modular construction (AMC) is a process by which the majority of the desired structure is built off-site and later fully assembled on-site. Rather than constructing every part sequentially on-site, as in conventional construction, this more efficient procedure puts together already made elements to complete the finished product. The difference between modular and automated modular construction is that the latter integrates the use of robotic systems to increase production speed and further reduce waste.

Recently, AMC has been rising in popularity among the construction industry for a few reasons. Because it is a more cost-effective alternative, many companies have turned to this method as an option to save money. Additionally, using AMC requires less building space since the structures can be made in factories. AMC is also a competitive option for construction companies since it presents clients with an opportunity to both spend and wait less.

There are many benefits associated with AMC. Aside from being efficient and cheaper, AMC also improves the quality of the end product. Built in a quality-controlled environment, structures are more likely to maintain consistently higher caliber. This means it is easier to control the materials and design, like creating surfaces with a certain cleanliness, or a certain ISO class rating. Furthermore, structural components developed off-site are easy to remodel or relocate; AMC offers flexibility of design.

Most important, AMC presents a much greener alternative to conventional building methods. Compared to the latter, AMC offers up to 90 percent less waste through the minimization of excess material usage. Since there is shorter construction on-site, AMC uses less energy and decreases site disturbances to the surrounding environment, reducing damage to ecosystems. Charlotte Weigel, a member of the non-profit Northeast Energy Efficiency Partnerships, reveals how AMC leads to a reduction in pollution through airtight buildings: “The better air sealing you get, the less heating and cooling losses you have, the less energy you use, the less emissions you have from operations of the building.”

When building a home or starting a new construction project, turn to AMC as a cost-effective, environmentally friendly and speedy choice. Additionally, promote this process among family and friends looking to start construction! Raising awareness about eco-friendly options can help ensure that we reduce our impact on the environment.
