Building Science Forum

February 27, 2018 @ 8:00 am to 4:00 pm


  • Why are we here- connections to Building Code, Step Code, green building programs, market niches, etc.

What is Building Science:

  • House as a System: heat/air/moisture and interrelations
  • The envelope, environmental separation and protecting it from damage (mainly moisture)
  • Unintended consequences and avoiding issues (increasing thermal resistance, vapour barrier materials, moisture-sensitive materials, in attention to air tightness
  • 4 barrier systems (criteria and examples):
    • Air
    • Vapour
    • Weather/moisture
    • Thermal
  • Climate – Specific Design:
    • Building for the environment
    • Section 9.36 requirements based on climate
    • Keeping moisture out
    • Dew Point
  • Barrier Systems Applications – Materials and Techniques:
    • Polyethylene Sheeting air barrier
    • Exterior foam insulation
    • Airtight Drywall Approach
    • Housewrap air barrier 4
    • Spray foam
    • ICF
    • Mixing and matching different systems
  • Foundation Systems:
    • Moisture Barriers
    • Insulation Options
    • Location of air barrier and vapour barrier
    • Drying
  • Air Leakage Air Tightness:
    • How tight is too tight?
    • Need for air: ventilation, make up, combustion
    • Ventilation Standards: Section 9.32 and F326
  • Mechanical Systems:
    • Space heating: options and right sizing/best practices
    • Domestic hot water heating: options and heat recovery
    • Ventilations: options
    • Sizing, installation, commissioning and homeowner education
  • Leveraging Synergies/Benefits
    • Best System to meet R value?
    • Capturing multiple benefits: right sizing equipment
  • Case Studies:
    • 2 case studies: renovation and new house
