More than 50 hvacr industry professionals gathered at the 12th Danfoss EnVisioneering symposium in Washington, D.C., on Nov. 18 to discuss new federal building initiatives and the state of the hvacr industry.
Speakers included policymakers, representatives from federal and state agencies, as well as industry experts.
In his opening remarks, Robert Wilkins, president of Danfoss North America, summarized the challenges facing the hvacr industry.
“We’re in the midst of the most important political discussions on energy and refrigerant issues that our industry has seen, issues that will impact our businesses as we move into the next decade and beyond,” Wilkins said.
Impact of American Recovery and Reinvestment Act
In the symposium’s first session, “Emerging Energy Efficiency Initiatives,” Chuck Clinton, senior advisor and lead regional coordinator, National Association of State Energy Officials noted that, under the ARRA, the federal government has earmarked more than $12 billion for national energy efficiency and renewable energy programs. He highlighted the “big three”: the Weatherization Assistance Program ($6.0 billion), which helps low-income consumers weatherize their homes; the State Energy Program ($3.1 billion), which focuses on commercial and institutional buildings; and the Energy Efficiency and Conservation Block Grant Program ($3.2 billion), managed largely by local municipalities.
Clinton also cited “incredible efforts being made with public utilities.” ARRA has allocated $4.5 billion for smart grid upgrades, with $100 million available for green jobs through the U.S. Department of Labor.
In spite of the opportunities and potential of these programs, Clinton cited several bureaucratic problems (the National Environmental Protection Act, Davis-Bacon Act and Buy American program), adding that states don’t always have the internal resources to effectively manage and execute energy efficiency programs. To date, only $200 million to $300 million for ARRA funds have actually been spent, but according to Clinton, the stage is now set for state and local governments to quickly expend all these ARRA dollars for their intended purposes.
“It’s at the same time exciting and challenging,” he said.
Clinton offered some advice to hvacr contractors who want to take advantage of these programs: They should contact their state energy office, research programs involving energy service companies (ESCOs) and tap into local programs, such as those implemented under the Block Grant.
Meanwhile, the federal government is doing its part to lead by example, according to Cyrus Nasseri, manager, Energy Efficiency Standards and Rule Making, Federal Energy Management Program, U.S. Department of Energy. In September, Obama signed Executive Order 13514, “Federal Leadership in Environmental, Energy and Economic Performance.” It requires federal agencies to increase energy efficiency; measure, report and reduce greenhouse gas emissions; conserve and protect water resources; eliminate waste, recycle and prevent pollution; and foster markets for sustainable technologies and environmentally preferable materials, products and services.
Another example of the federal government leading by example is Title V of the ARRA, Nasseri said. It allocates $4.5 billion to convert General Services Administration (GSA) facilities to high-performance green buildings.
What’s Next for Refrigerants?
In the symposium’s second session, “Refrigerants and the International Regime,” Mack McFarland, global environmental manager, DuPont Fluorochemicals, cited a study he co-authored earlier this year and published in the Proceedings of the National Academy of Sciences.
“A result of the study was the finding that, if we stabilized carbon dioxide in the atmosphere at 450 parts per million -- the consensus target of many countries -- but let HFC use continue along business-as-usual scenarios, then by 2050 the climate contribution of HFC emissions could be 28 to 45 percent as large as carbon dioxide,” he said.
He stressed that demand for HFC refrigerants is expected to grow due to the phaseout of CFCs and HCFCs. Most of that growth will come from developing countries such as China and India. McFarland cited that in 2007, developing countries were already using more HCFC refrigerants than developed countries did at the peak of their use and that most of these HCFCs would be replaced with HFCs over the coming decades in a business-as-usual case.
McFarland also presented a look at how the U.S. market, by sector, could meet cap and reduction targets set forth in the Waxman-Markey proposal.
Drusilla Hufford, director, Stratospheric Protection Division, U.S. Environmental Protection Agency recently participated in an international Meeting of Partners (MOP-21) in Egypt, during which the participants discussed phasing down global-warming HFC refrigerants globally through the Montreal Protocol. As a result, the developing countries requested more technical information about HFCs and their proposed phasedown.
“Montreal has a clear, binding commitment for developed and developing countries,” Hufford remarked in her optimism for Montreal to take responsibility for HFCs. Climate protection of Montreal is 5-6 times that of the Kyoto Protocol, according to the study McFarland presented during the same session.
Hufford views the request as a positive step and believes an international climate change conference, taking place right now in Copenhagen, Denmark, will provide “additional clarity” on the HFC issue. Furthermore, she believes prospects are bright for an international agreement on HFCs in 2010.
From War Zone to Homefront
In the symposium’s final session, “Fueling Energy Efficiency in the Public Sector,” Richard Andres, senior fellow, Institute for National Strategic Studies, National Defense University explained why the U.S. military is going green. They include supporting the war effort in Iraq and Afghanistan, saving money and contributing to national energy security.
For example, at large military bases in Afghanistan, the problems include rapidly growing energy demands, effectively heating and cooling shelters, other electricity demands, inefficient generators and a need for alternative, indigenous power sources. Andres said the HVAC&R industry can help the military by providing innovative, energy-efficient solutions to these complex problems.
In the symposium’s final presentation, Richard Lord, engineering fellow, Carrier Corporation, focused on the major initiatives revolving around refrigerants and energy efficiency and the role of total system efficiency to achieve a net zero building by 2030.
“Since the 1970s, the approach for improving building efficiency has been a prescriptive approach,” commented Lord. “Most efficiency metrics are component based and defined at a standard full-load rating condition, but hvac is somewhat unique because most of the operation is at lower ambients and part load, and the performance is not equivalent to full load.”
Lord further commented: “The building industry has been active in developing proposals for improved energy efficiency in response to the Energy Policy Act.”
He noted that a new version of ASHRAE Standard 90.1 is scheduled for completion in 2010. The new version’s energy efficiency standard is targeted to be 30 percent below that of the current standard, established in 2004.
What’s more, the industry is beginning to use new initiatives for Tier II and Tier III standards. These would be used for owners wanting to design a more efficient building, utilities seeking to reduce power and peak load, state and federal buildings requiring higher performance, and owners desiring LEED-certified buildings.
“We’ve made significant energy improvements, but we’re now approaching the limits of technology,” commented Lord. “The most logical approach is to focus on system level. These strategies include designing the building to reduce heating and cooling loads, and using renewable sources, energy recovery, natural lighting, natural ventilation, advanced controls, diagnostics and prognostics, and high-efficiency equipment. And we are seeing initiatives start to take shape, such as the ASHRAE Building Quotient introduced in June.”
Wilkins concluded that while there are no easy solutions to the industry’s challenges, significant progress is being made.
“The heart of our EnVisioneering Symposia Series, from the beginning, has been to bring informed ideas to the table – ideas that can put our industry on a path for success, so we can all make informed, strategic business decisions,” Wilkins said. “We look forward to continuing this informed dialogue in 2010.”
