Building an Airtight House Workshop

Center for EcoTechnology


This one-day workshop will enable participants to design and build airtight houses and to identify how air tightness must be addressed at each stage of construction. By following the recommendations in this training, participants will be able to meet the new air tightness standards in the 2012 International Energy Conservation Code (IECC).

Topics covered within this training include:

  • Air tightness requirements in building codes and energy efficiency programs
  • Blower door tests and typical results
  • Building envelope and types of air leakage pathways
  • Framing techniques to reduce air leakage at walls, floors, attics, and basements
  • Plumbing, electrical, HVAC, and drywall techniques to reduce air leakage
  • Other air sealing and insulation techniques
  • Designing airtight houses
  • Mechanical ventilation requirements

Workshop includes handouts, lunch and 1 day of classroom instruction. Continuing education hours include 5.5 hours for Massachusetts CSL, 5.5 hours for AIA, and 5.5 hours for BPI.
