A couple of weeks ago we posted information about Washington State’s new HVAC requirement. We are members of the local North Central Home Builders Association and along with the BIAW they are frustrated with the adoption of this new code and fear that it will cost contractors time and money to meet the new requirements. Read the summary below written by NCHBA.
“On February 7th, Judge Robert Bryan of the Federal District Court in Tacoma denied BIAW’s Motion for Summary Judgment and Granted the State Building Code Council’s Motion for Summary Judgment. The Judge issued a lengthy opinion, finding that Chapter 9 of Washington’s Energy Code was not preempted by Federal Law, even though it concerns the use of components that exceed federal standards…The Federal law states that credits under state energy codes must be on a one-to-one ratio to energy savings. In other words, a one point credit for installing a high efficiency furnace under Chapter 9 must equal the same amount of energy savings as the one point credit for building a house under 1,500 square feet…BIAW is appealing the ruling.”

This week one of our staff went to a WSU Extension Energy Program training in Wenatchee with a focus on duct sealing and testing requirements for the 2009 Washington State Energy Code for HVAC: 503.10.3 Sealing. We have two Energy Star Performance Technicians on staff so this class was more of a refresher course on duct testing but we did benefit from understanding more about the changes to the new HVAC requirements. Basically, the code is in a trial period. Contractors must test the HVAC now but do not have to meet the target rate of allowable leakage during this 120-day testing period. In April 2011 a judicial committee will listen to arguments from all sides and make a decision about the 503.10.3 Sealing WA State Energy Code.
We performed a HVAC leakage test on a home in South Wenatchee. The new construction home performed well. It would have passed the new requirements. It was interesting to note the small leakages that could be easily fixed by mastic. The equipment used for testing the HVAC includes a duct blaster, manometer and blower door which could add up to $5,000. This is a new expense to contractors. There is also discussion about requiring third party testing due to conflict of interest. Should HVAC contractors be able to test their own work?
Here are a few interesting facts we learned in class this week. Did you know that 40% of a home’s fresh air comes from the crawl space or garage? Thinking about cleaning those spaces right now…aren’t you!? This is also a good time to remind you to open your garage door any time the car is on. A family of four can emit up to 3 gallons of water into a home daily from sweating, showering, cooking, etc. Where do the 12 gallons of water go? Be sure to use your oven and bathroom exhaust fans regularly!
