Sustainability means many things to many people. For Austin, Texas-based GIGA Construction, the key driver of sustainability is energy independence. The company builds homes with integrated solar roofs with battery backup. One of those is Geo house, a net-positive energy home built for health, safety, and a sustainable, nature-inspired living experience. Designed by GIGA Construction, Geo house is the first project in the Houston 610 loop to pair a Tesla solar roof with battery backup for complete electrical grid independence.
