The Yannell Net Zero Energy Residence is a 3,000 sq. ft. single family home in Chicago that was designed with a goal of building a “net zero energy” house. The home produces more energy than it uses during the course of a year. The project involves the use of passive solar systems, a geothermal system, natural ventilation, solar thermal for domestic hot water and heating systems, and photovoltaics for generating on-site power. All systems for the building were incorporated into a complex energy model with several iterations to determine the most efficient building configuration. The project has achieved Leadership in Energy and Environmental Design (LEED©) for Homes Platinum level certification.
