Set at the foot of the Rocky Mountains, the "Zero Net Impact Home" helps define low impact, high performance homes with zero net ecological impact and zero net fossil fuel energy use. It will do this in a way accessible to the mainstream custom homebuilder for urban infill and suburban settings at a competitive cost. The project will house a growing family, the EcoBuild environmental materials rep and consulting firm office and a grandparent bedroom suite. An ample front terrace invites connection with passersby. The existing back carriage house provides affordable housing. It is also anticipated to offer "common house" facilities for a neighborhood cohousing/resource efficiency district prototype. An ecological footprint analysis by Victor Olgyay of RMI/ENSAR guides the design and determines how much off site mitigation is required after all energy & ecological loads have been minimized (using onsite restoration and offsite land preservation with carbon offsetting through investment in offsite energy efficiency). Feng Shui consultant Carole St Germaine and artist Juliana Forbes ensure it is a harmonious and beautiful building.
