Fenestration Simulation Software Training: Computer Simulation of Fenestration Products Using Berkeley Lab WINDOW and THERM

October 24, 2017
12:00 am - 12:00 am
Northbrook, IL
Posted by Dan Daugherty




The use of finite element analysis to determine heat gains/losses from fenestration products (windows, doors, skylights, etc) is very prevalent for research and design, as well as determining performance for meeting building code requirements.

This two-day instructor led course explains how to accurately use readily-available software to simulate the thermal performance of fenestration products. Participants will learn to setup and properly use Berkeley Lab WINDOW and THERM for determining a fenestration product’s U-factor, Solar Heat Gain Coefficient, Visible Transmittance, and Condensation Resistance.

This course is AIA CES Approved. AIA members will receive 16 HSU Learning Units for participating in this instructor led training.


Course Topics

  • Performance Values
  • Codes, Test Methods & Standards
  • Simulation Process: Berkeley Lab WINDOW
  • Simulation Process: THERM
  • Simulation Process: Putting it all Together


Upon completion of this course, participants will be able to:

  • Describe the factors that contribute to overall performance
  • Identify building codes and standards, and test methods related to fenestration software
  • Properly use the simulation process software, including Berkeley Lab WINDOW and THERM
  • Navigate and use the menus, toolbars, and libraries in these programs

Target Audience

  • Architects
  • Building Developers
  • Code Developers
  • Construction Industry
  • Consultants
  • Fenestration Manufacturers
  • Specification Writers

Continuing Education Units (CEUs)

  • 1.3 IACET CEUs; contact your local jurisdiction for CEU recognition.
