Draft PPS18: Renewable Energy
Annex 2: Passive Solar Design: Technical Constraints
9. PSD must form part of an holistic design approach to reduce the need for conventional energy sources in providing heating, light and ventilation and it should be used in conjunction with other low energy and efficiency measures.
10. The application of PSD may often be constrained to an extent by building and location specific factors. However at the present time the most significant barriers to its widespread application are lack of familiarity and a perception that PSD will inevitably produce buildings which are unconventional in appearance and difficult to market.
