DOE Takes First Step in Updating National Reference Standard for Commercial Buildings to 90.1-2013

• Control requirements for lighting alternations
• New requirements for individual fans
• Reduction of energy usage for large boilers
• Reduction of fan energy usage
• New efficiency requirements for commercial refrigeration
• More controls in more spaces and reduction of time to reduction or shut off of those controls
• Reduction of lighting power density in most building types

• 2013-14 ASHRAE President William P. “Bill” Bahnfleth, Ph.D., P.E., Fellow ASHRAE, ASME Fellow, professor of Architectural Engineering , director of Indoor Environmental Center,  The Pennsylvania State University
• James W. Bochat, president, Commissioning Concepts, Phoenix, Ariz.
• Tim McGinn, P.Eng., ASHRAE-Certified High Performance Building Design Professional, principal, DIALOG, Calgary, Alberta, Canada
• Jerry M. Sipes, Ph.D., P.E., vice president of engineering, Price Industries, Inc., Suwanee, Ga.

• Change the heating and refrigeration of the site.
• Construct a digester to produce biogas from the plant rejections (whey and white waters) and use the biogas in the production and buildings heating.
• Treat the digester effluent to be able to correspond to the environmental standards permitting use of an absorption field.
• Add ventilation (100 percent fresh air) in the cheese production area to ensure a positive pressure and correspond to Canadian Food Inspection Agency regulations.
• Change the High Temperature Short Time to be able to preheat the milk in the pasteurization using the refrigeration heat reject.
• Implement a control system performing survey of the mechanical system, automated control of main production processes, alarms handling and optimization of energy consumption.

• A geothermal heat pump energy plant consisting of the magnetic-bearing chiller, pumps, variable speed drives and controls was factory-assembled at an ISO-9001 facility and shipped to the site in portions for site assembly. This significantly reduced construction and commissioning time as well as risk related to varying on-site conditions and quality control.
• A control system using anticipatory predictive algorithms for the geothermal heat exchanger (GHX) seasonal and daily pre-conditioning to minimize energy use in lieu traditional “real-time” control that triggers closed-circuit cooling tower (CCCT) operation when the GHX temperature simply exceeds a setpoint. This means that the CCCT may operate during the night or during winter months to pre-condition the GHX for summer cooling and minimize summer daytime CCCT operation. Significant reductions in CCCT energy use and water use can be achieved by winter in lieu of summer operation due to lower ambient temperatures. The innovation is a control system that prevents excessive heat dumping in the winter.
• The control system measures and “learns” the actual building load imposed on the GHX and adjusts the preconditioning algorithms in relation to this intelligent model.
• Use of radiant cooling and active chilled beam sensible cooling via ground temperature water in lieu of chiller operation for much of the year.

• Commissioning Process Management Professional
• Building Energy Assessment Professional
• Operations & Performance Management Professional

• Table 6-2, Zone Air Distribution Effectiveness is modified to increase the ventilation effectiveness of underfloor air distribution systems that meet certain conditions. 
• Requirements for the quality of water used in humidification systems are modified and clarified.
• Building level pressurization requirements were clarified, including adding a definition of “exfiltration.” 
• A performance alternative to the prescriptive exhaust rates is added.  This approach differs from the Indoor Air Quality Procedure, the existing performance-based method for setting supply ventilation rates, in that monitoring of the concentrations of contaminants of concern is required and provides the basis for control of exhaust flow rates. 
• Some changes to the ventilation rates and space types in Table 6-1 are made.  These add refrigerated warehouses and change the ventilation rate for sports related spaces to include a per occupant component which then allows the use of demand controlled ventilation in these spaces. 
• The filtration requirement on air entering wetted cooling coils has been modified to change the MERV rating from 6 to 8.  This change will reduce potential for particulate deposition on the coils that could lead to biological or other contamination on the coils. 
• Toilet exhaust air that is cleaned to Class 1 may be recirculated. 

ASHRAE New York Tech Program Puts Special Focus on Tall Buildings, International Design, Building Performance

ATLANTA—It’s only appropriate that in a city known for skyscrapers—home to nearly 600—that the 2014 ASHRAE Winter Conference Technical Program puts a special focus on the design, development and operation of tall buildings when it visits New York City, Jan. 18-22.

"The ASHRAE Technical Program offers a great opportunity to learn from fellow professionals and experts,” Jon Cohen, New York Conference program chair, said. “Also, ASHRAE is continuously improving the Conference experience to incorporate additional networking opportunities, in addition to focusing on technical content."

The Technical Program begins Sunday, Jan. 19, and will follow the successful new format introduced earlier in the year at the 2013 Annual Conference: special hour-long interactive sessions with audience participation, followed by a networking coffee break.

The Technical Program features more than 200 sessions and offers dozens of opportunities to earn New York PDHs, AIA LUs and LEED AP credits.

In a nod to New York City, with its instantly recognizable skyline of towering buildings, the Tall Buildings: Performance Meets Policy track looks at opportunities in the design, development and operation of tall and super-tall buildings. The track also presents the measured and measurable use of utilities, envelope (infiltration and exfiltration), building pressure, waste handling, elevators, carbon and adaptive reuse. Sessions of interest include “Is ASHRAE Tall Enough for Tall Buildings?;” “Linking Tall Buildings’ Energy Use to Tenant Contribution to Economy;” and “Life Safety Issues with Tall Buildings.” The innovative features in tall buildings offer attendees design ideas for applications in smaller-sized buildings.

Additionally, as New York is a city on the world stage, the International Design track addresses innovative design strategies to meet environmental elements, geography and cultures. Examine “Energy Saving Strategy of Large-Scale University Facilities;” several sessions on “Cutting Edge Japanese Technologies;” “Sustainable Development in Africa;” and “European Union: Practical Benchmarking of HVAC System Energy Efficiency,” to name just a few.

Building Information Systems investigates how building control technologies are integrated and used for building management, operation and efficiency. An interesting session of note is “App, App and Away: Enabling Meaningful Work for the Building Professional with the Development of Quality Apps for Smartphones and Tablet Computers,” which explores the evolution of apps; the methods for developing and establishing a reliable app to provide an accessible and verifiable way for building professional to solve practical problems; and looks at areas of potential app development.

Hydronic System Design addresses innovative design, system components and research and case studies of their application, including unintended consequences. Sessions include the three part session “Efficient Technologies that are Also Economically Sustainable;” “Hydronic System Acoustics;” and “Energy Efficient Single Pipe Hydronic System Design for Large and Tall Buildings.”

The Environmental Health through Indoor Environmental Quality track includes developing, evaluating and predicting optimal indoor environmental conditions, and features case histories, lessons learned and advice to operators and designers about IEQ, as well as disaster recovery in buildings affected by hurricanes and floods. A few of the track offerings include “Indoor Air Environment and Heat Recovery Ventilation in a Passive School Building;” “A Comprehensive Look at Infectious Disease and Air Filtration in Healthcare Facilities: Energy Saving, IAQ Performance, and What Makes You Sick;” and “Lessons Learned from Storm Recovery.”

Additional tracks include Building Performance and Commissioning, Systems and Equipment and Fundamentals and Applications.

The Technical Program runs Sunday through Wednesday, Jan. 19-22, at the New York Hilton. Advance registration closes Dec. 31, after which registration fees increase to “onsite” pricing.  Register for the Conference at www.ashrae.org/newyork.

The International Air-Conditioning, Heating, Refrigerating Expo®, held in conjunction with the Winter Conference, runs Jan. 21-23. The Expo, held at the Javits Convention Center, takes place Tuesday, Wednesday, Thursday as opposed to the traditional Monday, Tuesday, Wednesday. More information is available at www.ahrexpo.com.

New Publication Provides Design Guidance on District Cooling Systems

ATLANTA – A newly published book from ASHRAE provides design guidance for all major aspects of district cooling systems.

“District Cooling Guide” includes guidance on central chiller plants, chilled-water distribution systems and consumer interconnection. 

District cooling systems are commonly used to serve applications like cities, educational campuses, major medical facilities and other large building complexes. When properly planned and executed, these systems can offer many environmental, efficiency and economic advantages over other means of supplying heating and cooling services, according to Gary Phetteplace, lead author of the guide, which was overseen by ASHRAE’s technical committee on district energy.

For district cooling systems to be successful, their components must be designed to function as a properly integrated system. In addition, owing to the large capital investments involved, such systems must have long lifetimes and they must be efficient and remain so over the long periods necessary to recover these substantial capital investments.

“To achieve efficient operation and long life, proper design is essential,” Phetteplace said. “This manual, along with a guide on district heating scheduled to be published in July 2013 will provide design guidance for all major aspects of district heating and cooling.

In addition to design guidance, the book contains a chapter dedicated to planning, with additional information on system enhancements and the integration of thermal storage into a district cooling system. Guidance on operations and maintenance, including several case studies, is provided to help operators ensure that systems function as intended.

The book is a useful resource for both the inexperienced designer as well as those immersed in the industry, such as consulting engineers with campus specialization, utility engineers, district cooling system operating engineers, central plant design engineers and chilled-water system designers.

The book serves a global audience, he said.  There is nothing inherent to the design approaches provided that would limit their applicability to a particular climate or region of the world. 

“Special emphasis was placed on ensuring that the guide addressed issues common to systems operating in the Arabian Gulf region where district cooling is seeing rapid growth,” Phetteplace said.

The book was funded in part through a contribution from Emirates Central Cooling Systems Corp., “Empower.”

The cost of the “District Cooling Guide” is $119 ($99, ASHRAE members). To order, contact ASHRAE Customer Contact Center at 1-800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 678-539-2129, or visit www.ashrae.org/bookstore.

The Indoor Environment—Health, Comfort and Productivity Track seeks papers highlighting the state of knowledge of the balance of environmental health and energy efficiency in buildings and research directions.

The Ground Source Heat Pumps State of the Art: Design, Performance and Research Track requires papers addressing all aspects of design that lead to optimally performing systems in addition to avoiding common pitfalls that lead to poorly performing systems. 

With low energy and zero energy buildings becoming more prevalent, there are many issues that arise with installation, startup, commissioning and operations and maintenance (O&M). The Installation, Commissioning, Operation, Maintenance of Existing Buildings Track seeks papers focusing on lessons learned, improvement of process and team communications and efforts to improve the installation, startup, O&M and commissioning of HVAC systems.

The Refrigeration Track has an emphasis on global perspectives on new refrigerants, variable refrigerant flow applications, magnetic bearing compressors and refrigerant management.  Papers on non-comfort cooling applications in food preservation and medical cryogenics are sought, also.

ASHRAE is known for its standards – their development and their adoption worldwide.  The Standards, Guidelines and Codes Track seeks papers highlighting the applications of ASHRAE’s standards to practice as well as European (CEN) and ISO standards that support building performance.

As with past ASHRAE Conferences, the Seattle Conference also seeks papers addressing advances and practices across HVAC&R systems, equipment, fundamentals and applications.

In addition, the Conference features a Professional Skills Track.

Conference paper abstracts are due Sept. 23, 2013. Upon acceptance, papers will be due Jan. 9, 2014. These papers undergo a single-blind review.

Full technical papers are due Sept. 23, 2013. Papers submitted for review must be both technically accurate and clearly written. These papers undergo a rigorous double-blind review and will be published in ASHRAE Transactions.

The General Services Administration announced another 60-day round of public comment Tuesday on which green building certifications the federal government should use.

GSA is required every five years to evaluate green building certifications for government use and make recommendations to the Energy Department about which systems to use. The Energy Department will then choose any combination of standards that best fit the government’s needs.

The Energy Department has avoided picking one certification standard so far. In 2010, the agency proposed a rule that would allow agencies to use any third-party standard that met Energy Department criteria.

GSA has been under fire from lawmakers, industry groups and advocacy organizations with a stake in which certification system is used.  More...
