We are excited the our LEED for Homes Projected "Gold" Oak Savanna project has received a HERS (Home Energy Rating System) score of 45! This is a very good score indeed! This is about as low as current technology can go for efficiency and comfort. To get this score you have about the most efficient HVAC, lowest duct leakage and great windows. The house is well sealed and the very comfortable. To get a lower score on the scale you will need renewable energy, such as solar or wind.
The U.S. Department of Energy (DOE) reports that a typical resale home scores 130 on the HERS Index, while a typical new home might rate 100. A home with a HERS Index Score of 45 is 55% more energy efficient than that standard new home, and 85% more efficient than a typical resale and has a annual energy savings of $1,616.00.  We would like to thank our HERS rater John Kuiper for doing a thorough job with the Blower Door Test and the Thermal Imaging of the project. We are finalizing the LEED for Homes paperwork and will have the final LEED certification rating shortly.
