Using passive solar design for housing

Article Abstract:

Solar energy can be used to provide a free and renewable source of domestic heating but it must be integrated with other aspects of the design of housing. Site layout, avoiding overshading by other buildings and allowing optimum south facing fenestration is vital. High levels of insulation with living rooms and most of the windows facing south gives the best results. Heating systems should respond quickly to changes in the environment and be fitted with thermostatic controls in each room. Conservatories only save energy if they are unheated and double glazed.

Energy must be integrated with refurb

Article Abstract:

Successful refurbishment of housing depends on the provision of affordable heating, adequate ventilation and reduction of heat loss. Measures to achieve these ends should be integrated with structural and other refurbishments so as to minimise the proportion of the cost spent on them. Energy efficiency reduces tenants fuel bills and also reduces the landlord's maintenance costs. Effectiveness of energy efficiency measures can be assessed by various computerised methods based on the Building Research Establishment's BREDEM model.

Energy efficiency in new housing; incorporating passive solar design

Article Abstract:

Houses built in Lewisham, London, England in 1983 were designed to maximise solar gain and to have high levels of insulation. The living areas face south and solar heating panels contribute to the water heating system. The houses are well insulated and draughtproofed and there is a gas fired warm air heating system that uses air from the roof space, thus recovering any heat lost to this area. Energy costs for the houses amount to 432 pounds sterling a year, a saving of 60% on houses built to the 1982 Building Regulations.
