The document discusses an energy code workshop that aims to raise awareness about energy codes and efficiency. It presents case studies of residential buildings in Phoenix that underwent energy efficient retrofits. The case studies show the pre-and post-HERS scores, estimated annual savings, water savings, purchase price, time on the market, and final sales price for each retrofitted home. The workshop also provides information on the benefits of energy codes and efficient buildings.
