COOLHOUSE demonstrates the use of passive cooling techniques in southern regions of Europe which are aimed at giving comfortable summer conditions in domestic scale buildings without using mechanical cooling systems. The project focussed on three sites, a private development of houses for sale in south west Portugal, an old peoples home in south France and a community centre in mid Italy. All are new buildings and were designed to provide cool internal conditions by passive means such as using solar shading and thermal mass, with the addition in all three cases of ground cooling pipes. This combination of measures was designed, constructed and monitored as part of the project. The ground pipe systems used PVC pipes buried 2-3 metres below ground with air drawn through using electric fans. The results demonstrate that the whole package of measures is successful in providing summer comfort. There is also benefits to the heating of the buildings in winter if the preheated air is used. The project concludes that there are no architectural difficulties in buried pipe system or providing and using internal thermal mass and that the COOLHOUSE package of measures could be replicated in different building types across all southern Europe.
