Peckham Architecture’s LEED Platinum home headquarters is Missouri’s first Passive House Institute US (PHIUS) Certified building. The fully accessible home features a 1,200-square-foot office and 2,500 square feet of living space for Nick and Diane Peckham, plus a garage and unheated 3-season porch. A photovoltaic system makes our headquarters net-positive, which means this building produces more electricity than it consumes. Super insulation, LED lighting, energy recovery ventilation, an instant hot water heater and Energy Star appliances further reduce the building’s energy requirement. This project has appeared in the Columbia Business Times and Columbia Missourian.
