October Dinner Presentation Re-cap

A special visit was made by Mr. Lee Loomis, Region I CTTC RVC. Lee made some opening remarks on the importance of CTTC Committee to the success at the local chapter. His remarks were well received. The dinner presentation by Mr. Robert Rybka of Belimo Americas presented the cost and operational advantages of implementing a PI control valve, which maintains constant flow independent of dynamic system pressure changes. Mr. Rybka described the linear output characteristics of the PI valve, which greatly improves output on coils and diminishes the effects of delta T syndrome when applied throughout the building to terminal units and equipment. The valve is available up to 3” diameter. When the PI valve is combined with a motorized 2-position isolation ball valve, coil trim savings can be realized by the elimination of check valves, which is inherently built-in to the PI valve’s operation.

Occupant Reactions to IEQ in Offices Presented at ASHRAE Conference

ATLANTA – Glare, noise level and cold drafts during winter months were top concerns of building occupants surveyed in an Australian study regarding indoor environmental quality (IEQ) in office buildings. Results of the survey will be shared at ASHRAE’s IAQ 2007: Healthy and Sustainable Buildings conference, Baltimore Oct. 14-17. For more information, visit www.iaq2007.org.

Occupants of two new buildings in Melbourne were asked about their satisfaction with design features and IEQ including temperature, airflow, air contaminants, sound pressure level, view, lighting and workspace configuration. Researchers at the University of Melbourne found that the occupants’ complaints dealt with areas related to building operation processes, lack of personal control and noise level. “The study confirms that it is useful for understanding how design and environ-mental quality design features impact occupants,” Maxwell Ashibuogu Chiazor, a doctoral student at the University of Mel-bourne, said. “The study shows that well-being and physiological discomfort are the two factors that account for occu-pants’ reactions to design and environmental quality. This information is useful for decisions about workplace configura-tion and building energy efficient design features.”

ASHRAE Seeks to Reach New Heights in New York City ATLANTA – ASHRAE will reach new heights in sustainability, professional development and HVAC&R technology at its 2008 Winter Meeting. Centered on the theme Reaching New Heights, a nod to the skyscraper skyline of New York City, the meeting takes place Jan. 19-23 at the New York Hilton. Held in conjunction with the meeting is the ASHRAE co-sponsored AHR Expo, Jan. 22-24, Javits Convention Center. For complete meeting information and to register, visit www.ashrae.org/newyork. Meeting highlights include the technical program, with its theme of Reaching New Heights in Net-Zero Energy Design, featuring more than 130 sessions with presentation of 59 papers. Sessions of special interest in the technical program include a roundtable featuring two of New York’s best-known owner/developer firms along with the engineering designers who bring their projects to reality. The session takes place at 11 a.m. Jan. 22, New York Hilton. A look at New York City’s Sustainability Plan, plaNYC 2030, is presented at 9:45 a.m. Jan. 20, New York Hilton. One goal of the plan is to reduce greenhouse gas emissions by more than 30 percent by 2030. Learn about the city’s efforts and ASHRAE’s role in meeting these goals. ASHRAE’s free public session focuses on HVAC System Design for Security and Sustainability. It is held at 3 p.m. Jan. 22 at Javits Convention Center. Steve Rizzo, author of Becoming a Humor Being, is keynote speaker at the plenary session held at 3:15 p.m. Jan. 19, New York Hilton. He shows people how to choose a healthy attitude both professionally and personally, learning how to succeed and enjoy their lives in the midst of challenging and changing times. “Concerns about climate change and the need to reduce energy consumption has created numerous challenges, or make that wonderful opportunities, for the built environment engineering community,” Kent Peterson, ASHRAE president, said. “Rising to the challenge will require equal parts of perseverance and innovation. Steve Rizzo illustrates how to embrace change as ASHRAE turns its technology engine against the daunting challenge of creating market viable net-zero energy buildings.” Sustainability is highlighted in the technical tours of facilities recognized around the world for their leadership in sustainable design. Buildings on the tour include Four Times Square, One Bryant Park, the Time and Life Building chiller plant, the Helena Apartment building, 7 World Trade Center and Time Warner Center. Sustainability also is highlighted at the ASHRAE Headquarters Hotel, the New York Hilton. Sustainability measures at the hotel include 90 percent fluorescent lighting; environmentally friendly refrigerants used in the chillers; preheating of hot water with steam condensate; and occupancy sensors installed in the meeting rooms. The hotel recently installed a 200KW fuel cell to generate electricity in a clean, environmental friendly way. The ASHRAE Learning Institute offers seven Professional Development Seminars and 14 short courses at the New York Hilton and Javits Convention Center. New sessions include Compliance with ANSI/ASHRAE/IESNA Standard 90.1-2007 and Energy Management in Existing Buildings. In addition, ASHRAE is debuting a program that allows attendees to connect online to carpool or share hotel rooms. Through ShareSpace, attendees can find others in their neighborhood who are attending the meeting, making it easier to find someone to share a cab to the airport and hotel or catch up with someone upon arrival in New York to share ground transportation. Sharing rides or rooms cuts down on energy and vehicle usage, as well as provides networking opportunities. To learn more, visit www.ashrae.org/newyork or www.spaceshare.com/ashrae.

Demand-Controlled Ventilation Requirements Proposed for ASHRAE 62.1 ATLANTA – Requirements for systems that use optional demand-controlled ventilation strategies are being proposed for ASHRAE’s ventilation standard. ANSI/ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings. Seven proposed addenda to the standard currently are open for public comment. Currently, the dynamic reset section of the standard allows designers to use optional controls to reset outdoor air intake flow and/or zone minimum airflow as conditions within the system change. For instance, it would allow a ventilation-system control approach that alters outdoor air intake flow based on time-of-day, if variations in zone population follow a predictable schedule, according to Dennis Stanke, committee chair. Proposed addendum 62g provides more specific requirements for such optional system controls, especially those his-torically called “demand controlled ventilation” (DCV) and based on the use of CO2 levels, as they relate to outdoor air-flow rates. For example, the addendum would require that optional DCV controls provide no less than the “area outdoor air rate” listed in Table 6-1, and that such controls maintain the minimum outdoor air intake flow no lower than the ex-haust airflow rate required by Section 6.2.8, Stanke said. “After public review and approval, this change should clarify DCV requirements,” he said. Also open for public comment is proposed addendum 62.1c, which would add performance-based air cleaning require-ments to section 6 of the standard. This would allow designers in jurisdictions outside of the United States to more read-ily determine when air cleaning is required. If approved, this addendum also would add air cleaning requirements for systems in non-attainment areas for particulate matter with diameter 2.5 microns (PM2.5)and smaller. Such systems would need to use intake air filters with minimum efficiency reporting value (MERV) 11. “Through better filtration, this would improve indoor air quality in many metropolitan areas of the United States,” Stanke said. Also open for public comment is addendum 62.1i, which replaces mandatory language requiring that outdoor air rates for environmental tobacco smoke (ETS) areas be determined using engineered methods with language indicating that increased outdoor air rates address odor and comfort for ETS areas, but not health. It also expands and clarifies a note to inform designers that increased outdoor airflow has not been shown to reduce health effects associated with ETS. Proposed addenda open for public comment from Sept. 14-Oct. 14, 2007, are: • Addendum f clarifies the meaning of “pool deck area” and associated outdoor airflow rate requirements. Proposed addenda open for public comment from Sept. 14-Oct. 29, 2007, are: • Addendum a clarifies air recirculation exceptions related to energy recovery systems and allows Class 2 air to be

transferred to toilet rooms. • Addendum c adds performance-based requirements for each contaminant so designers in jurisdictions outside of

the U.S. can more readily determine when air cleaning is required. • Addendum e updates references to industry standards and documents. • Addendum g provides additional requirements for demand controlled ventilation systems to augment the section

regarding dynamic reset. • Addendum h updates information regarding U.S. ambient air quality regulations. • Addendum i modifies the language in 6.2.9., Ventilation in Smoking Areas. It replaces requirements to use engi-

neered methods to determine ventilation in ETS areas with a requirement to use increased outdoor air rates to ad-dress odor and comfort for ETS areas, but not health.

Proposed addenda to ASHRAE standards are available during public review periods. To read the addenda or to com-ment, visit www.ashrae.org/publicreviews.

Energy-Saving Measures Proposed for ASHRAE/IESNA Standard 90.1 ATLANTA – Energy-savings measures related to variable air volume and cooling towers are being proposed for Stan-dard 90.1. ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. Fourteen pro-posed addenda to the standard currently are open for public comment. Under proposed addendum l, closed circuit cool-ing tower requirements to help reduce energy consumption would be added to the standard. The addendum would add minimum efficiency and certification requirements for both axial and centrifugal fan closed circuit cooling towers, also known as fluid coolers. “These requirements will provide consulting engineers, system designers and contractors with guidelines for the selection of independently certified, energy-efficient closed circuit cooling towers,” Mick Schwedler, chair of the 90.1 committee, said. “This change also will complement existing minimum and certification requirements for open circuit cooling towers, helping prevent confusion between the requirements for open vs. closed.” Also open for public comment is addendum n, which extends variable air volume (VAV) fan requirements for large sin-gle-zone units. VAV fan control currently is required in the standard for multiple-zone systems. Extending VAV control to single-zone units would save energy by reducing fan energy consumption when space cooling loads are reduced, he said. The change would take effect in 2012, allowing air conditioning unit manufacturers time to redesign and test their units. Manufacturers are currently redesigning to meet the 2010 phase-out of certain refrigerants. “Utility rebate programs and other incentives should encourage wider demand for these units and help this requirement to see real savings before 2012,” he said. In addition, addendum r, which would change informative Appendix G’s performance rating method into a normative ap-pendix, is open for comment. Making the performance rating method normative, or required, would allow its adoption into advanced energy standards, such as proposed Standard 189P, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, being developed by ASHRAE in conjunction with the Illuminating Engi-neering Society of North America and the U.S. Green Building Council. Additionally, language has been changed to make Appendix G enforceable allowing adoption by model codes. Proposed addenda open for review until Oct. 14, 2007, are: • Addendum h addresses any potential conflict between Standards 55, 62.1 and 90.1 and takes advantage of the en-

ergy savings potential of direct digital controls • Addendum j updates mechanical test procedures and references. • Addendum n extends VAV fan requirements for large single zone units. • Addendum q modifies vestibule requirements for Climate Zone 4. Proposed addenda open for public review until Oct. 29, 2007: • Addendum d modifies the requirements in both the lighting and envelope sections to better allow daylighting. • Addendum f expands the roof requirements to include cool roofs, which are shown by research to reduce the con-

duction loads through roofs into conditioned space. • Addendum g updates the building envelope criteria for metal buildings. • Addendum i applies a 4-zone lighting power density approach to exterior lighting requirements.

ASHRAE Notes HVAC&R Industry’s Role in Montreal Protocol Successes ATLANTA – As this week marks the 20th anniversary of the creation of the Montreal Protocol, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) celebrates the efforts of the heating, ventilating, air conditioning and refrigeration (HVAC&R) industries that have played a role in reducing ozone depletion. The Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. “ASHRAE has played a substantial role in stopping further ozone depletion by helping the industry to transition away from ozone-depleting refrigerants,” Kent Peterson, ASHRAE president, said. “The Montreal Protocol has shown that when we do what is right for mankind, our initial burden can turn to benefit. Not only has the Montreal Protocol improved the ozone layer, but it also initiated vast technological improvements in air conditioning equipment.” ASHRAE has continuously developed ANSI/ASHRAE Standard 15-2004, Safety Standard for Refrigeration Systems, and ANSI/ASHRAE Standard 34-2007, Designation and Safety Classification of Refrigerants as new refrigerants that are better for the ozone have been developed. In particular, ASHRAE has traced the development of HCFCs to replace CFCs, and then HFCs to replace HCFCs as technology improved. Now, there is a movement to use “natural” refrigerants such as carbon dioxide, ammonia, and hydrocarbons such as propane and butane. ASHRAE-funded research projects have also contributed to the successes of the Montreal Protocol. Research has included projects concerning ozone destruction, properties of refrigerants, and evaluation of CFC-alternative refrigerants. Since the Montreal Protocol, ASHRAE has written and updated its Position Document on Ozone-Depleting Substances, and the Society is currently writing a position document on natural refrigerants. Since the energy crisis of the 1970s in particular, ASHRAE has been a leader in energy efficiency. Work has included collaborations with the Clinton Climate Initiative, publications such as the Advanced Energy Design Guide series and the ASHRAE GreenGuide, and making ASHRAE’s flagship energy standard that is adopted into building codes, ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, increasingly more energy efficient.

Energy-Saving Measures Proposed for ASHRAE/IESNA Standard 90.1—continued • Addendum k revises Tables 6.8.1E and 7.8 to identify the specific sections of the referenced standards; updates to

reflect Federal efficiency levels for residential water heaters; and adds a requirement for electric table top water heaters.

• Addendum l adds minimum efficiency and certification requirements for both axial and centrifugal fan closed circuit cooling towers. In addition, a reference to the Cooling Technology Institute test standard for closed circuit cooling towers has been added.

• Addendum m establishes, effective Jan. 1, 2010, an additional path of compliance for water-cooled chillers. • Addendum o adds requirements for low voltage dry-type transformers. • Addendum p provides the necessary pressure credits for laboratory exhaust systems that allow prescriptive com-

pliance of systems serving fume hoods. • Addendum r changes informative Appendix G performance rating method into a normative appendix. Additionally,

some language has been modified to make the appendix enforceable. Proposed addenda to ASHRAE standards are available during public review periods. To read the addenda or to com-ment, visit www.ashrae.org/publicreviews.
