Polifactory came up with the concept for the self-sufficient HOUS.E+ for the 100 Mile House design competition, which concluded in May. Although not a winner, the home makes use of number of sustainable technologies currently in existence, but which have not yet been combined into one home. Designed for a suburban site in Vancouver, HOUS.E+ is built using soil excavated from the land to create the rammed earth walls. These breathable walls act as thermal mass to transfer warmth into the home. Rooms are sunk 2.5 meters into the ground to take advantage of constant temperatures in the earth and geothermal heating and cooling ensures an energy efficient climate control.
Embedded into the walls are a series of water pipes and micro hydro turbines that take advantage of gravity to generate energy from falling water. We’re not quite sure how that energy balance works out, but a rooftop photovoltaic system does generate plenty of energy for the house and the excess is fed back onto the grid. Using the home as a distributed energy source helps the city provide electricity through a smart grid system. Around the home is a aquaponics farm that grows and raises organic food on site and eliminates the need for transportation. The symbiotic environment raises aquatic animals like snails, crawfish, prawns and fish, while hydroponic vegetables feed off their affluent. The combination of all of the systems work in harmony to maintain a healthy and sustainable environment that could actually give back rather than detract.
