Of course, there’s another major benefit to having shorter runs. The shorter, more direct MEP layouts derived from AI-driven MEP design tools use less material than runs designed using conventional methods.
This can mean a significant decrease in the embodied carbon generated from the mining of raw materials as well as carbon emissions generated in material fabrication. In some cases, the AI-powered design software can determine whether it might be more cost-effective to meet design goals by reutilizing existing components, which can further lower embodied carbon.
Architecture 2030 predicts that embodied carbon will be responsible for nearly one half of the total new construction emissions between now and 2050, if current design practices don’t adapt to lower carbon emissions from buildings. While operational carbon emissions can be reduced over time by improvements made by the facilities department, embodied carbon cannot be changed after the building is erected. It’s critical to consider the amount of material being utilized and identify less wasteful strategies during design.
A 2019 report from the Carbon Leadership Forum sought to establish a likely estimate for the embodied carbon impacts for MEP components, primarily for commercial office buildings in the Pacific Northwest. The report noted that, because MEP systems are typically replaced every 10 to 20 years, the accumulated impacts of these systems can be significant. Overall, the researchers determined, the environmental impacts of MEP components are significant, averaging at 60 kg carbon dioxide equivalent emitted per square meter (CO2 e/m2) in the first year of operation, and doubling by year 15.
We’ve seen this in action. As one example, we developed a case study of a large public school system that was constructing a 122,000-square-foot elementary school by designing an MEP system that prioritized meeting carbon reduction goals along with better serving its budgetary demands.
Applying AI-driven software solutions to the MEP design generated an option that proved to save a total of 6,400 kg of embodied CO2 over the conventional design option. This was the direct result of a design that reduced the linear feet of copper piping, conduit and wire as well as steel and insulation used within HVAC ductwork. An added advantage of this improved MEP distribution plan was that it led to a nearly 12 percent reduction in cost as well.
