As we scale up construction and retrofits for high performance buildings, it is more vital than ever to include Cx in conversations surrounding the built environment and occupant health. Cx plays a crucial role in ensuring high standards are met and maintained beyond construction. Initiating the Cx process in design supports these goals, resulting in better coordination, training, and optimization. By serving as liaison between the design team and contractors, and through the support of holistic building operator training, Cx helps projects achieve long-term energy goals.
