How Low Can You Go? Case Studies of Low-energy Buildings
Track: Fundamentals
Room: 101 A
Sponsor: TC 02.08 Building Environmental Impacts and Sustainability; TC 04.07 Energy Calculations, TC 07.06 Systems Energy Utilization and TC 07.01 Integrated Building Design
Chair: Drury B. Crawley, Member, U.S. Department of Energy, Washington, D.C.
With recent interest in green buildings, a number of buildings designed to save significant amounts of energy have now been constructed. But do we know how these buildings are operating? This session brings together case studies of Low-energy, sustainability and integrated design in residential and commercial buildings. Topics include evaluation of individual technologies, design process, lessons learned, and long-term measured performance. This is part of a series on the operating performance of Low-energy buildings worldwide.

Seminar 1 (Intermediate)
Chilled Beams: Research and Case Studies of Benefits
Track: Fundamentals
Room: 201 B
Sponsor: TC 05.03 Room Air Distribution
Chair: Duncan Phillips, PhD, PE, Member, P. Eng, Rowan Williams Davies & Irwin, Guelph, ON, Canada
In general, the impact of energy gain within a space is controlled by three mechanisms. The use of tempered supply air, building thermal mass, and/or actively chilled building components (e.g. ceilings) all provide a means to control the temperature increases, or the perception of temperature increases, within an occupied region. It has been shown that the use of ventilation air to control temperature within a room is less efficient than using cooled building components. Using research and case studies, this seminar provides practical information on the use of chilled beams as part of an energy-efficient building thermal management system.

Chair: Steven L. Blanc, PE, Member, Pacific Gas and Electric Co., San Francisco, CA
Emulators are hybrid systems--partly simulation and partly real hardware--whose applications include product development and testing as well as education and training. Emulators for HVAC building systems have been a subject of research internationally for 20 years. During this time, a number of significant developments have occurred that indicate increasing practicality for emulators in building control and fault detection and diagnosis applications. This seminar focuses on recent development and uses of emulators and the implications for future development.

Chair: Michael R. Brambley, PhD, Member, Pacific Northwest National Laboratory, Richland, WA
How can you operate and maintain a building and its systems with constant pressure to reduce costs and staffing for operation and maintenance (O&M)? Many building operation teams face this situation. Yet, some organizations maintain or even improve their building operations, finding market value in improving their O&M. High quality O&M is a necessary cornerstone of high-performance buildings as we strive to make buildings more sustainable. Drawing from examples from health care, office buildings, and other facilities, speakers provide insight into processes for justifying and procuring the funding needed for high quality O&M.

Natural Ventilation in Schools: Boon or Bust?
Track: Applications
Room: 103 B
Sponsor: TC 02.03 Gaseous Air Contaminants and Gas Contaminant Removal Equipment
Chair: Christopher O. Muller, Member, Purafil, Inc., Doraville, GA
Natural ventilation in schools is used to lower cooling and ventilation costs. However, uncontrolled ventilation can allow contaminants to bypass filters and permit the introduction of excess moisture. Further, with the number of schools located in non-attainment areas for one or more of the U.S. Environmental Protection Agency's priority pollutants, natural ventilation can actually present increased health risks to a large segment of the student population. This program looks at ventilation in schools from the standpoint of outdoor air quality, air cleaning requirements of ASHRAE Standard 62.1-2004, and presents a case study highlighting one school district's experiences.

Moisture Performance of Details, Part 1: Claddings, Flashings, Wall Penetrations, Etc.
Track: Fundamentals
Room: 202A/B
Sponsor: TC 04.04 Building Materials and Building Envelope Performance
Chair: Wahid Maref, PhD, Member, National Research Council Canada, Ottawa, ON, Canada
Proper detailing of a building envelope is critical for providing adequate moisture control and performance. Water infiltration is often encountered during the service life of a building. Any opening in an envelope is a potential risk for water ingress that can lead to mould growth and wood decay. In this seminar, speakers give examples of good and poor detailing based on case studies from the field, laboratory experiments and hygrothermal modeling. They focus on envelope failures, symptoms, causes and remedial measures.

Technical Plenary Speaker--Engineers Without Borders
Bernard Amadei, University of Colorado, Boulder, CO
Room: 202A/B
With an estimated population increase of 2 billion people in the next two decades, unprecedented demand will exist for energy, food, water, land, transportation, waste disposal, health care and infrastructure. The role of engineers will be critical in fulfilling those demands from remote small communities to large urban areas. Amadei says a new generation of engineers must be trained who can better meet the challenges of the developing world and address the needs of the most destitute people on the planet. His presentation focuses on the challenges and opportunities with practicing engineering as well as the education of engineering. Also, he addresses the importance of integrating engineering with non-engineering disciplines when addressing the needs of developing communities.

The LEED[R] program supports leadership in energy and environmental design. Manufacturers are responding with products and systems that support green and sustainability goals. How do LEED designs work with other design goals? We need additional assurance beyond LEED certification that our buildings actually work for their intended purposes. We must also focus on construction materials used to control sound and vibration, mechanical equipment that affect noise levels, and interior environment assessments regarding comfort and performance.

Ground Source Heat Pumps for Sustainability
Track: Systems and Equipment
Room: 101 B
Sponsor: TC 06.08 Geothermal Energy Utilization
Chair: John Shonder, Member, Oak Ridge National Laboratory, Oak Ridge, TN
The high efficiency of ground source heat pumps (GSHPs) means that for a given space conditioning load, less energy is used, resulting in fewer pollutant emissions than most methods of heating and cooling. When combined with other technologies, GSHPs can be instrumental in achieving net zero energy use in homes and buildings. This seminar presents results of innovative projects using GSHPs--and the renewable resource the earth provides--to increase the sustainability of the buildings in which we live and work.
