Edgeland House is located on a rehabilitated brownfield site and is a modern re‐interpretation of one of the oldest housing typologies in North America, the Native American Pit House. The Pit House, typically sunken, takes advantage of the earth’s mass to maintain thermal comfort throughout the year. Like this timeless dwelling, Edgeland House’s relationship to the landscape both in terms of approach as well as building performance involves an insulative green roof and a 7‐foot excavation‐ gaining benefits from the earth’s mass to help it stay cooler in the summer and warmer in the winter.
Such an architectural setting presents an opportunity for maximum energy efficiency when combined with high performance systems such as the integrated hydronic HVAC system. The mechanical system combines: hydronic heating and a green roof for maximum energy efficiency.Lady Bird Johnson Wildflower Center collaborated to reintroduce over 40 native species of plants and wildflowers to the Edgeland House green roof and site, serving to help protect the local ecosystem.
