Daylighting, variable refrigerant flow, thermal bridging, labyrinth ventilation systems, ground-source heat pumps, dedicated outdoor-air systems, and hybrid systems will be among the topics discussed during ASHRAE’s second Energy Modeling Conference Oct. 1-3 at the Atlanta Marriott Buckhead.

Some 40 presentations, keynote speeches, networking, and a modeling-tools-software-developer session are planned.

“The ASHRAE Energy Modeling Conference: Tools for Designing High Performance Buildings addresses the most pressing issues facing modelers and those responsible for modeling in their companies,” Dennis Knight, chair of the conference, said. “Attendees ... will benefit by networking with other modelers and software developers and by the numerous hands-on modeling presentations, including case studies, updates on ASHRAE standards and codes, and current tools available in the marketplace, their applications, and workarounds.”

Conference highlights include:

• Calibrating existing-building energy models and a case study on retrofits.

• Lessons learned from Leadership in Energy and Environmental Design projects, featuring the top 10 mistakes modelers make.

• A large-building session showing how an extensive model was developed and including techniques for editing large data sets.

• A session presenting tools and techniques for contemporary systems, such as ground-source heat pumps and variable refrigerant flow.

• How cloud computing provides access to greater computing power, with examples of how this is improving project sustainability through more extensive modeling.

• Case studies that examine long-term implications of building-fabric modifications, air-distribution strategies, and performance standards on the extended use, cost, and energy consumption of environmental systems.

• Life-cycle-cost analysis of energy-conservation measures and the comparison of modeled to actual performance for whole buildings, existing buildings, and hybrid HVAC systems.

• An exploration of the effective use of building information modeling.

The conference features two keynote addresses: “Energy Modeling in the Design Process: From Life Cycle Costing to the AIA Energy Modeling Guide” by Daniel Nall, WSP Flack + Kurtz, New York, and “Will BIM and Building Energy Modeling Evolve to Meet the Demand?” by John Kennedy, Autodesk, Santa Rosa, Calif.

The conference also will feature “Market-Reality Session—Modeling Tools: What Works, What Doesn't and Workarounds,” during which modeling-software developers will explain how their software can or why it cannot model a scenario and what workarounds are available. Participating companies will include Carrier, IES, Sefaira, and Trane.

Registration is $515 for ASHRAE members and $565 for non-members through Sept. 23 ($540 and $590, respectively, after).
