IMEG has been ranked #25 on ENR magazine’s list of the 2023 Top 100 Green Design Firms, up three spots from 2022.  

The Top 100 companies are ranked according to revenue for design services generated in 2022 from projects that have been registered with or certified by a third-party organization that sets standards for measuring a building’s or facility’s environmental impact, energy efficiency, or carbon footprint. For IMEG, that amounted to 25 percent of the firm’s revenue last year—up from 17 percent the year before. 

IMEG Director of Sustainability Adam McMillen said the firm’s green design work is greater than what is reflected in the rankings, however. “The majority of IMEG’s building design projects incorporate sustainable design—making our green design footprint much larger than the percentage of projects that are third-party certified,” he said. 

Sustainable design is a long-standing tenet for IMEG, which has more than 150 staff accredited in green certification systems and a large portfolio of LEED, WELL, and net zero projects. The firm also is pursuing measures to reduce the operational and embodied carbon of its projects and has committed to industry-wide decarbonization initiatives including SE 2050, the AIA 2030 Commitment, and the National Academy of Medicine Action Collaborative on Decarbonizing the U.S. Health Sector. The firm also is a founding member of the Carbon Leadership Forum’s MEP 2040 Challenge. 

IMEG’s current sustainability projects include a community-scale geothermal system for the City of Ann Arbor, MI, one of 11 similar projects selected and funded by the U.S. Department of Energy’s (DOE) Geothermal Technologies Office. “This is a groundbreaking, collaborative project,” said McMillen, who is leading the analysis and design of the system. “It will serve as a model of what can be done to effect substantive energy and environmental solutions to improve all kinds of communities.”
