The Green Point Rating System by Build it Green is widely recognized as one of the best ways to rate the environmental impact of new construction and, just recently, existing homes. Green Point homes must exceed Title 24 efficiency standards by 15% and they must recycle at least 50% of construction debris. They must also meet standards for energy efficiency, indoor air quality, water use and community. 71 of the 95 residential green building initiatives in California reference Green Point standards and they will help ensure that homes in California are cutting energy use and reducing greenhouse gas emissions.
