1 NORTH CAROLINA ENERGY STAR CONFERENCE NOVEMBER 16, 2007 ENERGY STAR INDOOR AIR PACKAGE

2 OUTLINE What s so important about IAQ? What is the Indoor Air Package? How does it work?

3 WHAT ARE BUILDINGS FOR? People buy Homes because they need Protection from the elements and other dangers, and they have Aspirations to live in attractive, private, comfortable, healthy spaces with their families.

4 IT S NOT YOUR GRANDPA S HOME More Exposure to Mold - Colder surfaces with more insulation - More internal air flow and pressures - more exhaust fans - more forced air systems with fewer returns - more air pathways with open framing systems - Less drying potential More Exposure to Pollutants - Lower vent gas temperatures - Attached garages now standard - More VOC content in materials/finishes Less Fresh Air - They re tighter

5 SHOULD BUILDERS CARE ABOUT IAQ? Ath Asthma Eid Epidemic i (20 million Americans have it); ~2 million ER visits per year Increasing Risks of Radon >20,000 lung cancer deaths per year Increasing Respiratory Problems widespread indoor dampness (e.g. wet basements and visible mold) Chemical Pollutants EPA estimates t 2-5 times more than outdoor air Now consider this: People spend >90% of their time indoors, and >60% in their homes!

6 WHAT POLLUTANTS AFFECT IAQ? Biological pollutants Mold & Mildew Dust Mites & Pests Combustion Products CO, NO2, Smoke Radon & Soil gases Chemicals Formaldehyde Other VOC s Airborne Particles Dust, Pollen House design and construction can reduce exposure risk for indoor air pollutants!

7 DO HOMEBUYERS CARE ABOUT IAQ? Moisture and mold litigation - Up [~9,000 moisture and mold court cases - American Banker, 1/03] Home moisture problem inquiries - High [30%, double the next closest subject -NAHB Research Center] Asthma prevalence - High [19% of US households have at least 1 person with asthma -EPA] Air cleaner product sales - Up [$1.2 Billion annual sales - Levin, 2005] Radon mitigation sales -Up [300% increase in home radon mitigations since EPA]

8 DO HOMEBUYERS CARE ABOUT IAQ? Americans spend ~$16 Billion each year on indoor air quality products and services [LBNL report for EPA Indoor Environments Division, 2005]

9 CONSUMERS NEED BETTER CHOICES Air Cleaners Air Fresheners UV Lights

10 IAQ RISK REDUCTION PRINCIPLES? 1. Source Control eliminate, substitute, or modify pollutant sources 2. Dilution ventilate to dilute unavoidable pollutants 3. Filtration remove targeted t pollutants, t last resort after source control & dilution

11 OUTLINE What s so important about IAQ? What is the Indoor Air Package? How does it work?
