Résumé partiel
The climate of the southern Arava Valley is unique in Israel and unusual when compared to deserts worldwide. Winters are relatively mild, frost is rare and no occurrences of snow have been recorded within the valley. Summers are extremely hot during the day and at night the air temperature remains above 25°C. The region, from Eilat northwards 102 kilometers is part of the Eilot Regional Council. Within the valley 8 modern communities have been established in the past 50 years along with limited industrial, commercial and municipal facilities. The region has announced its commitment in the next decade to become energy independent using solar technologies and other alternative and renewable resources for producing electricity. The master plan for the region calls for tripling the population of around 3,000 residents in the next decade. Both of these goals depend on building housing units in each of the existing communities. The existing models of housing are recognized as energy in-efficient and inappropriate for the region. This is because they are copies of units built in (but not necessarily planned to be adapted to) other regions of the country and either transported to the Arava or built in situ according to plans that only marginally relate to the particular and extreme climate. The development of architectural strategies that are particular to this region with an emphasis on energy efficiency should be recognized as a component in the renewable energy plan and the physical development master plan of the regional council and the communities. The goal of this research project was to determine the components of residential buildings that would allow houses to be heated passively using solar gain and to be cooled using less energy than that currently needed for mechanical cooling. An analysis of the southern Arava’s climate presented three seasonal conditions that must be addressed when designing free running as well as low energy use buildings : a clear or partially cloudy skied winter during which sufficient heating can be provided using solar gain, spring and fall with comfortable ambient temperatures and risks of overheating from solar gain and summer in which ambient temperatures are above comfort levels during the day and most nights.
