It’s no secret that the building sector is a resource-intensive industry, but La Mesa, California-based nonprofit Green New World believes that the future of construction can and should be greener, healthier and energy-producing. Green New World created the House of PeacE (also known as Project HOPE), an autonomous and regenerative residential housing model that champions carbon-free living. Combining biophilic design with renewable energy systems and natural materials, Green New World’s first carbon-negative residential prototype — dubbed HOPEone — is slated for completion by 2019.
Conceived as a decentralized, autonomous housing model, Project House of PeacE (HOPE) will integrate water, energy, waste and food production and be adaptable to different climate zones. Shaped into a cluster of domes, the HOPEone prototype will be built from locally sourced earth using low-impact and affordable Superadobe construction methods. The building technique can be easily taught to people and can produce well-insulated and ecologically sound buildings with demonstrated resistance to earthquakes, fires and storms. The geometry of the domes is engineered to optimize energy-efficient thermal regulation and follow passive heating and cooling principles.
“Modules are selected based on a low-embodied energy and environmental footprint while being simple to recreate with basic skills and, as far as is possible, are constructed with locally available, low-cost and low-impact materials,” Green New World explained. “The first HOPE model, HOPEone, is nearing completion, where the productivity of the core bioenergy modules and carbon sequestration modules will be assessed for the development of future prototypes.”
In addition to energy and water conservation measures, the prototype will also harvest and generate its own resources. Depending on the location and climate conditions, different water harvesting systems will be installed and sized to meet the consumption of the inhabitants. The harvested water will be treated with ozone and subject to a three-stage purification, mineralization and alkalization treatment system. Solar photovoltaic panels will also be added to the buildings as will an anaerobic bioreactor for creating biogas used for heating and cooking.
