DOE Mold & Moisture
BPI CEUs: TBD
This workshop starts with the concepts of testing homes for air leakage using pressure. The use of a blower door for testing house tightness will be reviewed. Participants will learn techniques for proper equipment set up of the house for a single point test. Participants will learn to use the blower door as a tool to determine location of the air barrier and direct draft proofing of the house.
1. Understand principles of air movement and how they relate to building heat loss.
2. Understand the energy cost of air leakage in residential buildings.
3. Be able to define the pressure boundary and how to align it with the thermal boundary for maximum building performance.
4. Learn the various housing types common to your area, typical air leakage problems, and critical junction points associated with the construction.
5. Learn air-sealing techniques and appropriate materials to be used to seal a variety of chase-ways and by-passes: plumbing, chimneys, lights, knee walls etc.
6. Understand the causes and remedies for existing and potential moisture problems associated with air leakage.
7. Causes of and remedies for other existing and potential indoor air quality problems: pollutants, pathways, and driving force.
8. Be able to measure the dimensions of floors, walls, and ceilings to compute surface areas.
9. Be able to compute the volume of conditioned space.
10. Be able to determine Minimum ventilation level (MVL) or Building tightness limit (BTL) and Building Air flow standard (BAS) in accordance with ASHRAE 62.89 and 62.2 standards.
11. Become familiar with both Energy Conservatory and Retrotec air-leakage testing equipment. 12. Understand how to meet the requirements of Washington State Energy Code section 502.4.5 that requires air leakage testing for all new houses.
1. Blower door set-up and single-point test
2. Basic Zone pressure diagnostics to determine location and effectiveness of the air barrier.
