The concept of sustainability has gained interest in direct proportion to the recent increases in energy costs. There is a frequently overlooked initiative that can have the most significant impact on reducing energy usage in buildings and can set the stage for future efficiency initiatives: retrocommissioning.
Designing, constructing, or renovating high-performance buildings requires a whole building approach. This differs from the traditional design/build process, as the design team examines the integration of all building components and systems and determines how they best work together to save energy and reduce environmental impact.
Green school programs are touted mainly for saving energy, but research at the Georgia Tech Research Institute (GTRI) indicates that bettering a school’s indoor environment also increases health and comfort, which in turn promotes increased attendance, student attentiveness, and teaching effectiveness.
