LEARNINGS

• To reduce the heat gains during summer and promote heat gain during winter, reduce the HVAC loads and therefore

minimize energy costs.

• External shading devices are preferable and more effective than internal ones. This includes devices fixed to the

outside of the window or attached to building envelope. Among the operable units are louvers made of wood or
metal, exterior venetian blinds, shutters, awnings and fixed or movable overhangs.
