| Unprotected windows will readily transmit a considerable portion of the sun's radiation heat to pass through into a room, but acts as a barrier to the escape of this heat within. If this transmission of the sun's energy into buidings is not regulated, a phenomenon called the "greenhouse effect" will cause heat to build up to uncomfortable levels, which leads to reduced efficiency and a loss of productivity. |
