OASIS EFFECT TO MITIGATE HEAT ISLAND
Projections of future climate suggest increases in extreme temperatures particularly in mid latitudes. In addition, the effect of heat waves, which are becoming a major “summer killer, is exacerbated in urban areas owing to the heat island effect. Air conditioning (A/C) is a solution except that air cooled A/C still exacerbates the heat island and thus the heat waves. This paper presents a two-fold solution to counterbalance heat island: first, reject, in the ground or in water, the heat released by the chillers and second, use solar powered A/C and other solar devices so as to prevent solar energy from heating ambient air. Coupling this approach with cool surfaces, low energy building and transport (electric vehicles), it will be possible to create an oasis effect : urban areas will be cooler than the rural suburban areas. Equations giving the urban energy balance are presented and discussed.
