ibpsa-logo Hosted by the International Building Performance Simulation Association – Houston Chapter

As building performance simulation technology expands to areas beyond energy modeling, the field of simulations for envelope assessment and for building forensics remains relatively unexplored. Please join Christian Ozbun (Zero/Six Consulting) and Joe Fong (Walter P. Moore) as they delve into the possibilities by discussing their experiences with envelope performance simulation tools such as WUFI and the use of other simulation tools encompassing factors related to energy, daylight and building code.

 Learning Objectives:

  • Discuss how environment and energy code impact building enclosure performance
  • Identify which building performance simulation tools are available to enhance design process
  • Recognize the appropriate procedure to operate the simulation tools (i.e. WUFI & Therm)
    • Compatibility of weather barrier membranes with spray foam insulation.
    • Using hygrothermal simulation tools (WUFI) to detect moisture formation on weather barrier membranes.
    • Using hygrothermal simulation tools (WUFI) to select an appropriate building envelope assembly.
    • What assembly / climate conditions hygrothermal simulation tools (WUFI) are useful for.
