The Home Energy Score 8

HEScore Basics ■ DoE program created to allow comparison of estimated energy use between homes on a 1-10 scale ■ Each score corresponds to a range of energy uses, adjusted for climate. Homes are compared to a national average, not a reference home of similar size. ■ Easy to produce; takes less than an hour 9

How Building Age & Size Affect Score Initial Score vs Floor Area Initial Score vs Year Built 2020. 8000. 7000. 2000. 6000. 1980. 5000. Floor Area 1960. 4000. 1940. 3000. 1920. 2000. 1900. 1000. . 1880. . 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. . 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Score ■ Building age has little to no bearing on a home’s score ■ Large homes score lower than small homes – Especially influenced by window area ■ Small homes score across the 10-point scale 16

Berkeley Homes – Building Envelope ■ Majority are poorly insulated – 33% have no attic insulation – 83% have no floor insulation – 50% have no wall insulation ■ Very few have insulation up to code – 8% have attic insulation to code – 0% have floor or wall insulation to code ■ 63% have single paned windows. 17

Berkeley Homes – HVAC ■ Most houses are heated by natural gas ■ Heating Efficiency: Annual Fuel Utilization Efficiency – Code is 78% AFUE, best available 96% AFUE – Average: 76% AFUE – 12% of houses are at or above 90% AFUE – 64% are below code ■ 25% have natural gas wall furnaces ■ 5% have AC 18
