Modeling Underfloor Air Distribution Systems in IESVE

This one hour training course discusses how to model an underfloor air distribution system for purposes of evaluating energy performance. CFD analysis is not included in this session. The instructor uses a live example to walk users through the steps for:

  • Creating occupied and stratified zones in the model geometry in ModelIT
  • Distributing internal gains among occupied & stratified zones in Apache
  • Configuring UFAD systems from the ApHVAC Prototype Library
  • Accounting for heat gain to the supply airstream in the raised floor plenum
  • Evaluating results in VistaPro
  • Generating a baseline model for 90.1 PRM and ECB requirements

This training course is intended for users already familiar with the ModelIT, Apache, ApHVAC, and VistaPro applications within the Virtual Environment.

More information on modeling UFAD systems in the VE can be found in the ApHVAC User Guide Appendices. If you have any questions after viewing this training session, please contact [email protected] for assistance.
