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.
