Peckham Architecture’s LEED Platinum home headquarters is Missouri’s first Passive House Institute US (PHIUS) Certified building. Our 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. This green building is net-positive, which means that it produces more electricity than it consumes. We achieved this level of energy efficiency using green building tools including solar panels, super insulation, LED lights, ERV (energy recovery ventilation), a tankless water heater and Energy Star appliances. This project has appeared in the Columbia Business Times and Columbia Missourian.
