Roofs are another source of building energy loss, but roofing design and materials can help to reduce the amount of cooling required in certain climates by reflecting solar heat rather than absorbing it. Roof systems may contribute to up to 33% of building losses, depending on the building type and climate zone in which it is located. High performance roof systems and technologies are available the market that can help reduce the building losses through the roofs and help in designing high performance commercial building.

TOOLSHeating, ventilation, and air conditioning account for roughly 37% of all the energy used in commercial buildings, a large percentage of which routinely escapes as heat through the building envelope. Vacuum Insulated Panels (VIPs) are a promising technology that present opportunities to mitigate those losses, especially in regions with extreme climates and high utility costs.Building Envelope Webinars for Roofs Webinar CollectionThis toolkit features webinars presented by the Better Buildings Alliance and Oak Ridge National Laboratory that focus on advancing the latest innovations for roofs on commercial buildings.In the inaugural meeting of the Building Envelope Tech Team, participants discussed goals, new resources, and technologies to improve the energy efficiency of walls, windows, and roofs.
