Papers addressing advances in alternative technologies and net-zero buildings, as well as HVACR fundamentals and commissioning, are being sought for the American Society of Heating, Refrigerating and Air-Conditioning Engineers' (ASHRAE’s) 2011 Annual Conference in Montreal, Quebec, Canada.

The deadline for paper submissions is Sept. 17. For complete information on tracks, contacts, and submittal requirements, visit www.ashrae.org/montreal.

The 2011 Annual Conference will take place June 25-29. Alternative-technologies paper topics include photovoltaic (PV), geothermal, wind-power, and variable-refrigerant-volume (VRV) systems; solar and other technologies; as well as how these systems affect the first and operating costs of a building. Papers describing the science behind emerging technologies incorporated into net-zero-energy (NZE) design also are sought.

Net-zero-buildings paper topics include NZE design, cost to achieve NZE buildings, existing NZE buildings, and operation and maintenance issues and costs. Case studies illustrating how to achieve NZE design are sought as well. Engineering-tools paper topics include the range of different energy-modeling and building-information-modeling tools available, their use and specific applications and integrated approaches.

Papers from owner or architect perspectives or case studies that illustrate modeling techniques are requested. Additionally, papers are sought for tracks on commissioning, HVAC systems, HVAC fundamentals and applications, professional skills, and refrigeration. Full-length technical papers or conference-paper abstracts (400 words or less) can be submitted.
