What Can Earn the ENERGY STAR?

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

Complete Thermal Enclosure System Third-party Verification Complete Heating & Cooling System Complete Water Management System Energy-Efficient Lighting and Appliances Version 3 Features Standard on Every Home

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

1.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.

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. Improved technology reduces heat transfer Multiple panes insulate better Low-E glass reflects heat & UV rays Inert gas fills insulate better Warm edge spacers reduce heat flow & condensation

HEATING AND COOLING SYSTEM Efficient 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.

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.

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

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

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

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

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

THIRD-PARTY VERIFICATION Field Verification Blower Door TestDuct Blaster Test

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

THIRD-PARTY VERIFICATION Trusted Symbol of Energy Efficiency Show homebuyers the proof.

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
