The non-profit San Diego Renewable Energy Society (SDRES) invites property owners, building and corporate sustainability managers to join San Diego’s leading solar and energy efficiency innovators for an interactive, behind-the-scenes tour of six money-saving commercial energy solutions as part the 13th San Diego Sustainability Tour. The tour begins at San Diego Gas & Electric’s Energy Innovation Center, where buses will be waiting to take guests to other sites, and includes Q&A with local contractors and property owners who are saving money, earning tax credits, and creating more sustainable work and living spaces.
