Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it.

As fears grow amongst climate scientists that the world may be close to reaching a tipping point leading to runaway global warming, there’s a growing recognition that the forthcoming UN climate conference in Copenhagen must deliver dramatic and binding targets to cut carbon.
