Prototype Home That Can Solve Challenges Of The 21st Century: Housing, Energy, Water, Waste, Sanitation and Carbon.

ENTRY DESCRIPTION

An auto-sufficient home capable of harvesting water from rain or air, recycling water 4-times, processing sewage, growing biofuel from sewage, sequestering carbon dioxide, renewable energy and passive climate regulation in a healthy habitat made with stabilized earth.

With this house I wish to provide solutions to emerging global environmental challenges. Since the first prototype home has the shape of a peace symbol it’s named the House of PeacE aka HOPE. The design and materials of the building work in tandem with passive thermal regulation elements such as solar, geothermal, wind, water and mass to provide a comfortable stable living climate. Integration of active systems is required in extreme climates. The primary source of energy is the sun which is used to provide electricity, hotwater, space heating and cooling. Water is harvested from rain or air moisture and treated by safe chemical-free methods. Radical water conservation of up to 68% is achieved by 4-fold reuse and efficient design. Designs also exist for 6-fold water reuse. The integrative Water- Waste -Energy System is designed to work in tandem. The water savings and ultra-high efficiency toilet make it possible to integrate a septic bioreactor that converts biowaste into biomethane. A dual kitchen sink is used on one side for greywater recycling for washing food and dishes and the other side equipped with a compost grinder to feed the bioreactor. Integration of a photobioreactor provides additional biomass for biomethane generation which is used for cooking, hotwater and a peak demand generator. The photobioreactor is integrated in a closed loop to mimic the natural carbon cycle. The exhaust generated from biomethane combustion in addition to the effluent from the bioreactor is used to feed the photobioreactor. In turn, the photobioreactor feeds the bioreactor which produces biogas, effluent and sludge. Carbon leaves the system as effluent or sludge which is converted to carbon and nitrogen rich organic fertilizer. HOPE provides a simple affordable low-tech solution to global housing that can be reproduced and built by a layman.
