Friends Center Green RoofIn Posse is a subsidiary of AKF Group and was founded by Rob Diemer in 2010 as an outgrowth of his practice at AKF specializing in sustainable design and high performance systems.  We come from traditional MEP Engineering roots and have a passion for high performance and sustainable buildings.  We provide consulting and engineering services both independently of AKF and as part of integrated teams with AKF.

We hope to create a world in which buildings generate more energy than they use, produce clean water instead of waste, create habit instead of destroying it and fully serve the needs of the community.  Not only are we focused on reducing the environmental impact of the buildings we design and work on, we also strive to reduce the environmental and social impact of our business operations.

In Posse is proud to be a certified B Corporation in recognition of our attention to the triple bottom line of people, planet and profit.  We strive to limit our carbon footprint and offset 100% of what we can’t eliminate through carbon offsets purchased from Renewable Choice.  Our members provide countless hours of volunteer time individually and twice a year, the entire firm provides service to local non-profits who are helping the environment and the community.
