  1. Great Resource for Sustainable Terms


    This is a great resource for sustainable terms, thank you for posting this!

  2. Energy Saving


    California Title 24 was released by the CEC as a building and remodeling efficiency standard in order to save energy and other natural resources. It is estimated that California Title 24 could save over $100 billion dollars in natural resources over the course of the next few years, as $56 billion has already been saved since 1978. Can you believe the energy we can be saving. The affects it has on our world could dramatic change. Thanks Robert
