Selection of solar shading should always be one of the first steps in the design of HVAC systems as the demand of power and use of energy is greatly influenced by solar shading. It is always more feasible to prevent extra heat entering to the building than use energy for cooling to remove the heat in summer, and in winter take maximum benefit of free solar heating. The integration of solar shading with building HVAC systems is more and more important in the future to optimize the investment and operation costs of buildings.

This guidebook gives a solid background on the physics of solar radiation and its behaviour in window with solar shading systems. Major focus of the guidebook is on the effect of solar shading in the use of energy for cooling, heating and lighting. The book gives also practical guidance for selection, installation and operation of solar shading as well as future trends in integration of HVAC-systems with solar control.
