In Posse provides consulting and engineering design services for high performance, deep green projects with a special expertise in net-zero energy.  At In Posse, we focus exclusively on the energy and sustainable design sectors of the built environment for clients in a broad range of market sectors.  Our services address all aspects of building performance including modeling and analysis of building systems, engineering high performance building systems, commissioning and occupant education and engagement.  In Posse is a subsidiary of AKF Group and is headquartered in Philadelphia, PA with an office in New York, NY.

In Posse is Latin for in potential and our goal is to help realize the potential for each building to perform at the highest levels. We believe that buildings can only perform at their best if occupants understand their impact on energy use. A strict focus on building design and performance overlooks the people factor; therefore we provide a comprehensive array of services to educate building users so they understand their role in the energy equation. Innovative thinking, technical skills, a collaborative attitude, consistent performance and top quality service are the attributes that define In Posse.
