Added Benefit to Owning a High Performance Home

Blower DoorYou regularly hear a builder marketing his homes as Energy Star certified, Earth Advantage certified, Green built, High Performance, etc. What does this really mean? In fact there is a term, “Greenwashing”, which defines the practice of disingenuously marketing “green”. If you do your homework, you will find most builders are doing the bare minimums to get there certifications. Simply increasing the efficiency of the HVAC system, adding insulation to increase the insulating factor, increasing the efficiency of windows and introducing fresh into the home which is usually by a fan added to a utility room. This of course is a simplified list, but you get the picture.

Unfortunately, what you don’t hear about very often is the testing and third party inspections that go into these homes to get the certifications. I believe that one of the more important benefits of this performance building process is the scrutiny that the homes go through. The level of quality and performance that is demanded to get even the minimum level of certification forces the builder to build a much better built home than a code built home utilizing the municipality inspectors, ie. City, County and State building inspectors.

One test that is required is a door test. This test evaluates what air is lost when the home is pressurized. Meaning, when the home has air drawn from it, where would the air leak in through; wall outlets, wall switches, windows, the base of walls, etc. To prevent this leakage, it is a requirement of the builder to fully seal the base of the walls at the floor, around the windows, wall outlet boxes for switches and plugs, ceiling lights, etc.

Again, when you hear a builder talk about their certification, ask questions. What level of certification do they have for their homes and what measures have they taken during construction. But in the end, even at the minimum level of certification, these homes are built to a much higher standard than most code build homes. This will have a lasting effect on the livability and resale over time because of this. All new homes look great when new however, it’s how they stand the test of time that identifies how well built they actually were.
