Draft PPS18: Renewable Energy
Annex 2 Passive Solar Design: Technology

6. Virtually all buildings enjoy free energy and light from the sun; the objective in PSD is to maximise this benefit by using simple design approaches which intentionally enable buildings to function more effectively and provide a comfortable environment for living or working. It is acknowledged that not all aspects of PSD are of direct concern to Planning Control, for example the use of dense materials to store heat.
7. An important distinction must be drawn between the use of PSD in housing and other buildings. In housing the primary objectives are to capture light and heat. In the case of other buildings light is also important but generally excess heat is a problem during periods of high solar gain, making the main purpose of PSD the removal of excess heat whilst avoiding the use of air conditioning.
