  9. What Can Earn the ENERGY STAR?

  10. Traditional Home Components • Several components work together to consume energy in a home: • Occupants • Thermal envelope • Lighting and electrical systems • Water heating and storage • Foundation • HVAC systems • Appliances and plumbing systems

  11. Version 3 FeaturesStandard on Every Home Complete Thermal Enclosure System Complete Heating & Cooling System Complete Water Management System Energy-Efficient Lighting and Appliances Third-partyVerification

  12. 1. THERMAL ENCLOSURE SYSTEMa. Comprehensive air sealing • Typical home: ½ mile of cracks & gaps around windows and doors • Hundreds of holes for pipes, ventilation ducts, lighting, and wiring.

  13. THERMAL ENCLOSURE SYSTEM • b. Properly installed insulation Studies show insulation can lose 2/3 or more of its rated performance with even minor installation defects.

  14. Improved technology reduces heat transfer Low-E glass reflects heat & UV rays Inert gas fills insulate better Multiple panes insulate better Warm edge spacers reduce heat flow & condensation 1. THERMAL ENCLOSURE SYSTEM c. High-performance windows • 25-50% of the demand on a home’s mechanical system is due to heat from the windows.

  15. HEATING AND COOLING SYSTEMEfficient Heating & Cooling Equipment As much as ½ the energy used in homes goes to heating and cooling. Therefore, equipment plays a critical role in the efficiency of a home.

  16. HEATING AND COOLING SYSTEM Trained and Certified Contractors • Proper training and certifications for installing HVAC systems in ENERGY STAR qualified homes. • Version 3 HVAC contractors must by approved by ACCA, a recognized industry oversight organization.

  17. WATER MANAGEMENT SYSTEMBuilding Materials Proper material selection, along with weather protection during construction, helps prevent water and mold-damage in ENERGY STAR homes.

  18. What We’re Avoiding Missing or defective window flashing allows water to leak into the walland create mold and durability problems. Missing & improper window flashing

  19. LIGHTING & APPLIANCES Advanced Lighting ENERGY STAR lighting offers homebuyers significant cost savings and longer lifetimes than standard products.

  20. Less Heat, More LightENERGY STAR qualified light fixtures use pin-based CFL bulbs that generate significantly less heat and distribute light more efficiently than standard incandescent bulbs. 5 Watts Light [40%] 6 Watts Light [10%] 100% Electricity 100% Electricity 54 Watts Heat [90%] 8 Watts Heat [60%] 13 Watt CFL 60 Watt Incandescent

  21. ENERGY-EFFICIENT LIGHTING & APPLIANCESENERGY STAR Qualified Appliances Appliances account for nearly percent of household energy use 20

  22. THIRD-PARTY VERIFICATIONField Verification Blower Door Test Duct Blaster Test

  23. THIRD-PARTY VERIFICATIONQuality Assurance ENERGY STAR requires more inspections and testing than homes merely built to code.

  24. THIRD-PARTY VERIFICATIONTrusted Symbol of Energy Efficiency Show homebuyers the proof.

  25. THIRD-PARTY VERIFICATIONTrusted Symbol of Energy Efficiency

  26. How Do HERS Ratings Factor In to the Sale? • Most of the Features and Benefits we just covered are applicable to HERS Ratings • Your Plans and Specs are used in the Analysis to Develop a HERS Index for the Home • The HERS Index is equivalent to the MPG for cars – But the lower the number the better the performance – Think Golf Score • HERS Ratings are a vehicle to Energy Code Compliance

  27. ENERGY STAR V3 • Wall-to-Wall Comfort • Peace of Mind • Enduring Quality • Proven Value • Dependable Performance
