The national, US government-backed symbol for energy efficiency WHAT IS ENERGY STAR? The national, US government-backed symbol for energy efficiency Should be consistent for most presentations 3

ENERGY STAR BACKGROUND Launched in 1992 for computers Grown to products across 40+ categories 1995 - new homes 1999 - efficient buildings 2003 - updated logo Sold 1+ billion products Prevented greenhouse gas emissions equivalent to those from 18 million vehicles Before After Products include heating and cooling equipment, programmable thermostats (now’s the time to buy!), (shameless plug for heating products), consumer electronics, We meet our goals when you sell more. Our success is measured by how many metric tons of carbon dioxide we prevent. This is a measurement of how many ENERGY STAR qualified products are sold. Fixtures offer us HUGE carbon savings potential. Why do we care so much about your products??? 4

ENERGY STAR LABELED HOMES Voluntary Defines Truly Energy Efficient Builder Recognition Government-Backed Label Third-Party Verified

ENERGY STAR FOR HOMES GROWTH United States Homes Labeled * Based on reports for Q1 and Q2

ENERGY STAR FOR HOMES GROWTH North Carolina Homes Labeled

ENERGY STAR FOR HOMES METRICS 800,000+ Labeled Homes Total ~20-60+% Market Penetration >60% of the top 100 Builders >65% ENERGY STAR ‘Brand’ recognition

ENERGY STAR Homes To earn the ENERGY STAR label a home must be at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC). ENERGY STAR Homes are 20–30% more efficient than standard homes. Tax Credit is 50% efficient more

Features of ENERGY STAR Qualified New Homes 1. Effective Insulation Properly installed and inspected insulation in floors, walls, and attics ensures even temperatures throughout the house, reduced energy use, and increased comfort. 2. High-Performance Windows Energy-efficient windows employ advanced technologies, such as protective coatings and improved frames, to help keep heat in during winter and out during summer. These windows also block damaging ultraviolet sunlight that can discolor carpets and furnishings. 3. Tight Construction and Ducts Sealing holes and cracks in the home's "envelope" and in heating and cooling duct systems helps reduce drafts, moisture, dust, pollen, and noise. A tightly sealed home improves comfort and indoor air quality while reducing utility and maintenance.

Features of ENERGY STAR Qualified New Homes 4. Efficient Heating and Cooling Equipment In addition to using less energy to operate, energy-efficient heating and cooling systems can be quieter, reduce indoor humidity, and improve the overall comfort of the home. 5. Efficient Products ENERGY STAR qualified homes may also be equipped with ENERGY STAR qualified products — lighting fixtures, compact fluorescent bulbs, ventilation fans, and appliances, such as refrigerators, dishwashers, and washing machines. 6. Third-Party Verification With the help of independent Home Energy Raters, ENERGY STAR builders choose the most appropriate energy-saving features for their homes. Raters conduct onsite testing and inspections to verify the energy efficiency measures, as well as insulation, air tightness, and duct sealing details.

ENERGY STAR Homes ENERGY STAR qualified homes can include a variety of 'tried-and-true' energy-efficient features that contribute to improved home quality and homeowner comfort, and to lower energy demand and reduced air pollution.

Common locations of air infiltration Resulting Problems Other leaks in the shell (house) continue to reduce comfort and waste money. The AC system is perhaps not properly sized and therefore does not run enough to pull humidity out of the house The inspection also looks at mechanical systems including furnace, boilers, air conditioner and ducts. Duct leakage and other duct problems can be a source of comfort problems, health and safety issues and reduced energy efficiency. 13
