Final energy testing

The Peregrine on Lot 20 attractively landscaped.

WE PASSED OUR FINAL ENERGY TEST WITH FLYING COLORS!

There is a lot of technical information contained in this blog.  Please take some time to read and familiarize yourself with the terminology and the requirements.

The blower door test determines how well the building is sealed.  This test is a new requirement in the Washington State Energy Code.  All new homes in Washington State must pass this test.  The minimum standard to pass is measured at 0.00030 Specific Leakage Area (SLA).  Here are the results for Lot 20 Duct Testing Calculator and for Lot 21 Duct Testing Calculator. They are identical:  SLA = 0.00013.  This indicates that our homes, the Peregrine floor plans are .5666% better than the standard which adds to your comfort, lowers your energy usage and saves you money!

This plus a 4 Star Built Green rating is why this house is a perfect investment!

Robert Stockmann of Pinnacle Inspections, who performed the tests, adds: “Here are some useful links…it’s a long explanation at times but the old axiom “Build it Tight & Ventilate it Right” equates to superior indoor air comfort and increased energy savings for the homeowners.  No matter how well or how much insulation you have in a home, it doesn’t matter one bit if the house is “ leaky”.  Once air is allowed to infiltrate the wall, floor and ceiling cavities of a home in an uncontrolled manner, it basically renders the insulation useless, produces uncomfortable indoor climates, increases energy consumption for heating and/or cooling AND it can cause numerous other issues, such as interior moisture condensation issues.  When the homes reach a specified air infiltration rate, then mechanical ventilation is required to produce necessary air exchanges within the building.  This is why the HRV is an excellent choice to provide a good balanced exchange of bad indoor air and fresh outdoor air.”  We have installed the Panasonic ERV  to maintain the indoor air quality in the Peregrine homes.

Heating and Ventilation

Heating and ventilation in the Peregrine models at The Highlands.

The first photo below shows the two BioSmart® Therapeutic Ceramic Far Infrared In-wall Heaters and the Panasonic ERV, energy recovery ventilation installed in the Greatroom.   The Panasonic ERV is the black box in the middle and the two heaters are to the left and right of the ERV.  The WhisperComfort energy recovery ventilating fan provides indoor air quality with a balance of supply and exhaust air.  These systems work together to provide an integrated, therapeutic heating and indoor air quality system for maximum comfort and energy savings.

The second photo shows how we sealed all wall, floor and ceiling penetrations. All of this specialty sealing is in preparation for the final installation of insulation and radiant barriers.
