Points raised in the report relevant to housing

Housing built to 2002 Building Regulations will be uncomfortably warm to live in by 2020. By 2080 internal temperatures could reach 40°C. It suggests that air conditioning and mechanical ventilation will be necessary, adding that the air conditioning should be driven by PVs or other renewable energy sources. Natural ventilation will be counterproductive when outside temperature exceeds internal temperature.

It recommends masonry buildings with high thermal mass over timber frame lightweight construction. Smaller windows with shutters are recommended. On south facing elevations solar blinds will be essential. Where buildings are deficient in thermal mass a possible solution is to apply a phase change material to internal surfaces. These are now becoming available in plaster form (see p. 137).

There is a conflict here with the principle of optimising passive solar energy. The answer could be removable or sliding heat reflective panels which reduce the glazed area in summer. Fitting louvres or external shutters to windows or internal blinds is recommended.

Arup concludes that by 2080 London will have the climate of the Mediterranean coast and we should consider adopting similar building techniques to that region.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
