1. Skylight Area: A skylight is a light-transmitting structure that forms all or part of the roof space of a building for daylighting purposes. Total skylight area of the proposed building can be inputted in this tab.
  2. Skylight SHGC: Solar Heat Gain Coefficient for the skylight glass. The higher the SHGC value more heat the space will receive. SHGC value varies from 0 to 1.
  3. Skylight U-Value: This measures how effective is your skylight material as an insulator. Lower U-value means higher insulation which ultimately leads to energy savings.
