The glass envelope of the house is a high performance composite incorporating electronic and mechanical systems including ventilation. It employs an electrochromic coating; a small voltage changes the opacity, and a photovoltaic coating; incident sunlight is converted to electric energy. The energy generated powers the window and ventilation systems. This is a process of ephemeralization, where a single, fine, multi functional envelope takes the place of the separate cultures of structure, aesthetics and service systems.A single integrated loom cables services to all domestic spaces. It uses dry break self sealing, spill proof, couplers, like the LPG hose at your local petrol station, to allow rapid connection to any service. The loom conducts grey water and sewage out, mains water in, electricity in, telephone and optical in and data through. This allows connection for any function in a given space, and different ones at different times. A living space can be cabled and serviced in a single operation. The loom is fixed in a channel in the floor. Access ports can be added at any time, positioned at any point along the loom.The kitchen is conceived as a campsite within the home, an integrated appliance, easily movable to the outside deck or any other part of the house. It is made up of compact interchangeable and upgradeable modules for food preparation.The bathroom module, extrapolated from aircraft toilet modules is designed around a recycling unit. This recycles and distils grey water though an energy efficient evacuated evaporation system. All the fittings can be retracted allowing other uses for the bathroom space.A heat pump drives a thermal cycle in the building to collect, dissipate, store and redistribute heat for year round temperature control. Heat is stored chemically within the hollow support columns. The floors and roof act as a ducted circulation system like a Ôprinted circuitÕ for heating and cooling. Air ducts are cut into composite floor and roofing material. Such a building can be likened to a mammal in its ability to conserve its temperature by controlling the permeability of its outer skin.
