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.
Vacuum Insulated Panels for Roofing Case StudyAccording to a report by the Green Proving Ground Program, VIPs (Vacuum Insulation Panels) save energy while meeting the demands of real-world construction.
