How We Build - Habitat for Humanity of Greater Sacramento
Habitat for Humanity of Greater Sacramento builds GREEN because we believe we have a moral and fiscal responsibility to our families and our community to design and build our homes in an environmentally responsible way.
LEEDing the way
HFH Greater Sacramento joined the US Green Building Council (USGBC) in 2009 and has built 21 LEED (Leadership in Energy and Environmental Design) certified homes to date. The USGBC LEED system awards points for energy efficiency and sustainability and has recognition levels at Basic, Silver, Gold and Platinum.
Our Mahogany Street home in Del Paso Heights earned HFH Greater Sacramento the honor of being the 7th Habitat affiliate, of over 1,500 nationwide to achieve the coveted Platinum ranking.
The average energy consumption for all of our LEED certified homes is $10/home from our local utility service provider SMUD. We just completed our first all-electric net-zero home, located at 4025 32nd Street in the Oak Park community. So far, the homeowner has not paid for electricity.
In 2010, we were awarded “Achievement in Excellence” by the US Green Building Council for our LEED program. In 2011, we finished among the top 3 finalists in the nation for “Affordable projects of the Year” at the USGBC Summit.

Green Building Strategies and results
Our goal is to build homes that are energy efficient today and that will remain energy efficient in the future, with ratings that are at least 20% to 25% higher than current California Title 24 standards require. These homes will include photovoltaic solar systems on the roof to supplement electricity. The onsite solar power source can reduce electricity bills by as much as 70%.
