On the Way to GreenOver thirty million existing homes in USA
80% of these will still be standing in 50 years
We cannot rely on new construction alone to give us energy & water benefits
Retrofitting existing stock will provide energy and water savings and provide jobs – local construction jobs
Low Hanging FruitStart SimpleConvert those incandescents to CFL, or better yet, LEDsSeal duct runs with low-toxic mastic and keep conditioned air where it belongs

Improve Indoor Air QualityRepair Water Damaged AreasCreate Shoe Removal Locations
Clean Construction
Cold Air Returns are Cleaned and Covered to prevent dust entering
Dust and debris free – This is what any remodel should look like before applying sheetrock
Zipwall Dust Barrier System – used to protect other areas in the remodel from dust and debris produced by active construction area

Home Performance Testing Duct-Blaster Testing A. Monitor for a Duct-Blaster Test
Test used by Energy Auditors to determine relative amount and location of leaks in ducted forced-air systems
B. Duct-BlasterUse a smoke machine to blow smoke into the sealed ducts of the forced-air system to help locate leaks
C. Smoke filling a roomThis home was preparing to put up sheet-rock the next day, because with traditional construction and NO third-party testing, a forced-air system installed such as it was would have been overlooked. Because of the Energy-Star required Third-Party Verification, this home was able to fix the leaky ducts and create a higher performing heating system for the new occupants. Otherwise, this problem is never captured before the sheet-rock goes up! And, unfortunately, that is how most new homes are constructed.

Home Performance Testing Blower-Door Testing D. Blower-Door Test
A test to determine the air leakage in a home. It uses a variable-speed fan to pressurize or depressurize a house. The pressure difference between the inside and outside air at various fan-induced pressures indicates the amount of air leakage. An Energy Auditor looks around the house to pinpoint locations where there are leaks and reports to the building on cost-effective measures to seal the leaks
