The Sky House achieves one of the oldest ambitions of architecture… to suspend the body in space.The architectural components used to achieve the illusion of corporeal suspension, are simultaneously the essential ingredients for a low-carbon house in arid climates.Sustainability in the service of pleasure. The house is half house half pool. The interior temperature of the house is regulated by the pool water. The exterior wall of the pool forms the interior walls of the house. The wall works as a heat exchange device. To maximize exchange it is shaped as a series of stacked continuous cooling ribs, assuming a form for maximum surface to air exchange.The filtration system of the pool runs the water by a tank of Phase Change Materials (PCM) encapsulated in 3” diameter plastic capsules. During the day the PCM absorb the solar energy embedded in the water from the sun. At night the PCM releases this energy back into the water and subsequently back into the house
