ENGEO leads a Geo Heat Pump Retrofit in San Ramon, CA (3:35)

Sacramento State Capital

We strive to turn California’s regulations and policies into green action by government, consumers, and businesses. These include the installation or retrofit of GHPs (geothermal heat pumps) to eliminate greenhouse gas generation by buildings, and to foster their achievement of LEED-certified ratings and a march toward carbonless ZeroNetEnergy, the most sustainable building option of all. Our advocacy is matched with increasing education and training to develop installation professionals and maintain quality standards for evaluation and measurement that prove performance of GHP technology.
