Systems

• Environmental considerations should be a priority when making the choice of fuel.

• High efficiency heating systems should be installed, for example condensing boilers, and space heating and hot water systems should be appropriately sized.

• In wet central heating systems thermostatic radiator valves are essential.

• Controls, programmers, and thermostats should be appropriate to the task and correctly positioned and their operation easily understood by occupants.

• The heating system should be geared to the thermal response of the building fabric and occupancy pattern of the dwelling.

• Hot water storage cisterns and the distribution system should be effectively insulated.

• Where there is a high standard of air tightness a heat recovery ventilation system is essential.

• Ventilation of utility areas, bathrooms and kitchens is especially desirable to prevent condensation.

• The venting of hot air in summer should be considered.

• The environmental benefits of conservatories are cancelled out if they are centrally heated.

Also linked to evolving climate change will be the need to take account of increased wind speeds, extremes of climate, heat episodes leading to the drying out of ground at normal foundation level. A guide to revised building practices has been published as part of the government's advice as to how business can respond to climate change. It includes such points as:

• deeper foundations to cope with ground shrinkage;

• more robust walls and roofs to withstand intense storms;

• orientation to present shorter elevation to prevailing winds;

• Consider more aerodynamic forms (e.g. Swiss Re, p. 158-159).

To conclude this chapter it is worth summarising points from an Arup report of Autumn 2004 on the likely impact of climate change on UK buildings.

Renewable Energy Eco Friendly

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.
