WebThe Heat Gain through Partition, Floor or Ceiling formula is defined as the term given to a temperature rise within a space due to heat from the sun (solar radiation), heat from surfaces (long-wave infrared radiation), heat originating from other sources within the space (such as heating appliances, ovens, people, mechanical systems, lights and computers) …

WebSolar Heat Gain Coefficient (SHGC) is the ratio of the measured solar heat through a given glass type to the incident solar heat on the glass. The measured values are affected by the air films on either side of the glass, absorbtivity and by other factors. SHGC is therefore less than SC (about 10% to 15%).
