2015 ASHRAE Energy Modeling Conference:
Tools for Designing High Performance Buildings
September 30 – October 2, 2015
Atlanta, GA


General Information

The conference built on past ASHRAE Energy Modeling Conferences by addressing the industry need for “how to” do certain aspects of energy and building simulation.

The conference theme was “Making the Difference with Modeling: From Concept to Facility Management” and broadly covered modeling from start to finish through high quality case study presentations.

The purpose of the conference was to facilitate communication and coordination within the energy modeling and building simulation industry and software developers to advance the industry’s ability to better model high performance buildings and to advance the practitioner’s understanding of the application of existing and new tools, new technology and processes for energy modeling, whole building simulation and building HVAC system design.

Participants in the conference were day-to-day energy modeling and building simulation practicing professionals, principals of consulting firms, consulting engineers, other practicing professionals and software developers.

ASHRAE LowDown Showdown

New to the ASHRAE Energy Modeling Conference was the ASHRAE LowDown Showdown modeling challenge sponsored by the Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL). The ASHRAE LowDown showcased the work of several teams competing to model a net zero or below building. 

Eight teams competed in the inaugural ASHRAE LowDown Showdown Modeling Challenge on Thurs., Oct. 1 at the ASHRAE Energy Modeling Conference. The teams were:

  • Autodesk
  • Carrier HAP
  • DesignBuilder
  • EnergyPlus (volunteer-led team)
  • eQUEST (volunteer-led team)
  • IES
  • Sefaira
  • Trane TRACE

Each team was coached by a participating vendor and comprised of registered attendees who signed up to play a position on each team such as engineer, architect, designer and energy modelers.  The teams were given a common playing field “Model Building Requirements” and then each team had a little over three months to create their plan and to deliver their “Proposed Building.” 

At the conference each team presented their results. One member from each team presented the results of their teams’ effort in 15 minute PowerPoint presentation.  A Q&A session was held after all the presentations were completed.  Teams were judged on a number of criteria including lowest energy use results, creativity, innovative workflow and teamwork.  The conference attendees voted electronically on the best presentation on the day of the Showdown in each of the above four categories and the results were announced at a reception that evening.
