BEFORE THE AUDIT:
The owner of this home was trained as an engineer and had very specific needs that he demanded to be met down to the smallest detail. After interviewing several other companies for the job and kicking them out of the door, we were selected because he felt comfortable that our team is as technically skilled and detail oriented as he is. His goal was to tighten up the home and make it less penetrable to air flow in addition to upgrading his boiler and hot water tank.
WHAT THE AUDIT FOUND:
We performed several diagnostic tests for him, including blower door tests, duct blaster tests for the AC, infrared camera and other zonal pressure diagnostics. The results of these diagnostics showed that the home had a high leakage rate and several “hot walls” or walls that affect air temperature and cause more burden for equipment. These walls are most commonly a result of having little or no insulation in the wall cavities. In addition to these problems with the building envelope, The homeowner’s heating system and hot water heater were outdated, failing, and in need of replacement.
WHAT WAS SUGGESTED:
In order to meet his detailed needs for high efficiency solutions we proposed and installed a high efficiency Peerless boiler with an attached indirect hot water tank. To solve the problems of hot walls and air penetrations in the building envelope, we used a high density foam to insulate and seal the attic knee walls and we air sealed all accessible penetrations including the attic plane where the wall top-plates meet the open attic space.
