BPC head trainer/BPI certification proctor, Chris Clay, was in Fairbanks, AK in late November 2011 proctoring 9 Building Analyst candidates. Chris reports that the climate dynamics there are pretty impressive. The Alaskan climate presents special challenges for the area’s energy auditors with extreme temperatures, varied housing stock, and an abundance of very tight houses. Although it was 15-20 degrees below zero and the attic access of the test house was at the end of a 20 ft ladder the experience was great because the basics of heat, air, and moisture flow are so easy to see. Chris listed some examples:
- -5 pascals of stack effect in a 900 CFM50 house
- frost on triple pane windows
- 12 pascals of draft pressure in a boiler chimney in a combustion appliance zone that measured -10 pascals relative to the outside.
Chris greatly appreciated the assistance provided by Interior Weatherization of Fairbanks in securing the certification house and from AlaskaWorks Partnership and Alaska Housing Finance Corporation in sponsoring the certifcation event.
