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

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
