"The architecture is a fresh take on Tiverton's classic farm typology," explains Kellfelz. The buildings give a nod to local precedents but have updated details and overall aesthetic, which incorporates many sustainable elements. This includes fantastic energy efficiency. In addition to the wind turbine as a source of 85 percent of the homes' power, the homes incorporate high-efficiency heat pumps, cellulose insulation, double-hung low-e windows, Energy Star light fixtures and appliances, and passive solar canopies and porches.
