High-Rise Multifamily and Commercial Building Energy Performance Simulation Software Verification Task Force

There is a growing interest by developers and utility sponsored programs in being able to rate the energy performance of high rise multifamily and commercial buildings. Currently there is no national standard for the verification of high-rise multifamily and commercial building performance simulation software programs.

To meet this need, RESNET will develop and adopt a new simulation software verification standard and testing procedures. This will be accomplished by working with commercial building energy efficiency programs such as the New Buildings Institute, LEED, the ENERGY STAR Homes Multi-Family High Rise Pilot Program, and RESNET international affiliates such as the Shanghai Real Estate Science and Research Institute and the Japan Energy Star Council.

This effort will focus on developing accreditation procedures for software simulation tools used in performance-based analysis. A set of national commercial building modeling protocols is also being developed in a separate work effort by the New Buildings Institute and the Natural Resources Defense Council with funding from the Energy Foundation. This effort will also be coordinated with the Environmental Protection Agency's modeling efforts with the ENERGY STAR Homes Multi-Family High Rise Pilot Program.

The following are the members of the task force:

  • Shelby Allen, TRC Energy Services
  • Kevin Ault, Integrated Energy Design
  • Chris Balbach, Performance Systems Development
  • James Brauer, Jr., TexEnergy Solutions
  • Michael A. Browne, Advanced Building Analysis

RESNET has recruited a Working Group that will prepare the drafts during the development process that the task force will review on comment on. Members of the High-Rise Multifamily and Commercial Building Energy Performance Simulation Software Verification Working Group are:

  • Philip Fairey, Florida Solar Energy Center
  • David Goldstein, Natural Resources Defense Council
  • Michael Holtz, Architectural Energy Corproation
  • Ron Judkoff, National Renewable Energy Laboratory
  • David Lee, Environmental Protection Agency
  • Courtney Moriarta, Steven Winter Associates
  • Mike Optiz, U.S. Green Building Council
  • Nick Zigelbaum, New Buildings Institute

The working group has proposed the following work plan for developing the RESNET building energy performance index:

  • Establish procedures for accreditation of commercial building software
    • Software must pass ASHRAE Standard 140, Section 5.2 tests (specific test number to be determined)
    • Establish RESNET software pass/fail criteria (Standard 140 does not specify acceptance criteria)
    • Software must provide for automatic generation of reference buildings
  • Establish minimum standards for the rating method
    • Reference building
      • As defined by ASHRAE 90.1-2004, Appendix G
        • California ACM HVAC Systems Map (rule base)
        • Residential lighting budgets
