The applicability of passive solar techniques to the refurbishment of non domestic buildings in the UK.

Expenditure on refurbishment of non-domestic buildings is expected to increase at a faster rate than that on new building. It is, therefore, important that the applicability and potential of daylighting, complete/partial natural ventilation and other passive solar techniques are assessed for use in refurbishment projects. This study assessed the technical and economic feasibility, and market acceptability of incorporating passive solar measures into non-domestic buildings at the time of refurbishment. It quantified the likely future take-up of passive solar refurbishment in non-domestic buildings and identified the individual building types likely to provide the greatest opportunities for this type of strategy. The likely national energy savings to be achieved from passive solar refurbishment of non-domestic buildings up to the year 2015 were estimated.
