But right now, what’s going on in densely populated asian cities is no movie: according to a recent united nations report, natural light has become 10 to 25 percent dimmer in cities such as Bejing, Karachi, shanghai, and new delhi as 2-mile-thick clouds of pollution spread rapidly. This issue of solutions focuses on the private sector in the united states and examines whether it can drive efficiency during a recession that’s been brewing for months. This focus on domestic issues makes sense given the recent Presidential elections and incoming leaders who will likely be more comfortable intervening in the private energy sector. But the industry must never lose sight of the importance of the global community – the so-called “brown cloud” that keeps sunlight out of those asian cities stretches from the arabian Peninsula to China to the westernmost portion of the Pacific ocean. It’s attributable solely to the burning of too much fossil fuel and biomass and will creep closer to the united states if not kept in check. u.s. leaders will take a measured, aggressive approach to solving our energy problems with public policy. But no one should discount the contention that what goes on outside of the country can have dramatic consequences for the rest of the world. as always, we welcome your suggestions and feedback on this issue.

Energy efficiency advocates use this anecdote regularly, most often to contrast Carter’s energy policy with the policies of subsequent presidents, who removed Carter’s solar panels and diverted attention from energy policy to focus on other agenda. But Carter, the cardigan-wearing, woodburning President whose doctrine deemed interference with u.s. oil production in the Persian Gulf to be an act of extreme hostility, routinely backed up symbolic energy steps like the white House solar panels with practical ones.

This concept is emerging in public policy discussions. Today, the United States faces another energy crisis. Few would argue the importance of the country’s energy interests, and many assert that the changing of the guard in the White House is, once again, a symbolic step that needs practical action to follow. What those practical actions look like, and, what actions and policies the government implements is at the forefront of our industry’s agenda. Could the private sector provide the necessary practical actions on its own, without government intervention that nudges efficiency forward? It may not have the chance to find out. Energy and the Environments We Build Ideally, technologies like solar panels and wind turbines soon become cheaper than the fossil fuels that they replace while machines become more energy-efficient whether they use fossil fuel or alternatives. This progress is already underway: a 13 SEER air conditioning system, for example, uses about 23 percent less energy than a 10 SEER system. As energy prices continue to fluctuate, the best strategy to manage expenses might be to replace old, outdated equipment and avoid the unnecessary costs they incur. This concept is emerging in public policy discussions. It’s important to remember that buildings are integral units, not pieced-together appliances and systems. For example, engineers can integrate efficient air conditioning systems with heat recovery systems to produce hot water at a lower cost. Conservation means making the most with available resources—in this case, existing systems and technologies or strategies to make the interplay between them more efficient—not buying every new technology that comes along. In some places, use of photovoltaics has nearly doubled every two years since 2002, and the renewable solar tariffs and net metering that come with these technologies are enormous incentives to encourage their continued use. Some buildings are beginning to use this technology in their marketing and leasing materials. 23% 4 Energy and Public Policy Upcoming years could see change in many areas: the composition of the private sector, government oversight and regulations, business incentives to minimize energy use, and investments in conservation technology could all shift as a result of the credit crisis and the 2008 United States presidential elections. With changes in the executive and legislative branches, government intervention into the energy industry could easily increase. Surely there will be change. Appointment of energy efficiency advocates to the cabinet could change the regulatory landscape. Requirements for increased system energy efficiency could force building owners to retrofit older, less efficient equipment. A $150 billion government-led investment fund, as Obama proposed during his campaign, could compete directly with private equity firms for investment in the most-progressive energy technology. The change to 13 SEER is a 30 percent improvement in efficiency that results in 23 percent less energy consumption. This is just one example of the progress already made in reducing energy use and in lowering the cost of energy-efficient technologies.

For domestic and work environments we make, such policy would nudge energy prices upward and drive demand for efficiency technology to reduce exposure or mitigate risk. For manufacturers, new policy focused on climate change, and on HFCs in particular, would create a fork in the road: innovative manufacturers will see opportunities, while the rest will see an obstacle. Currently, public policy does not do a lot to encourage phaseout of appliances dependent on HFCs, so advocacy organizations have stepped up to educate policy makers about these chemicals. An additional concern is the potential for investments in energy efficiency to slow due to domestic recession. The Obama administration has a plan that is particularly alluring. It would invest $150 billion during the next ten years in private efforts to create or nurture clean-energy technology. The administration would have great incentive to push this policy through because, aside from driving innovation, the fund would create jobs during a time when domestic unemployment is comparatively high. It is tough to say what the actual affects of such capital infusion might be. While overall investments in the technology sector have dwindled recently with the economic downturn, investments in green technology have remained strong. But industry insiders predict that innovation will continue to originate in the United States, even if production is moved offshore to countries like China or India where labor rates are lower. All other factors considered, recession might be the best time to invest heavily in innovative technology because emerging from downturns historically involves changing the status quo. Where public policy takes the environments we build in the near future won’t be awfully surprising. Many technologies that policy may soon require already exist as options today. Energy efficiency requirements for appliances have been increased several times in the past and may be shortly revisited. High-performance building designations, such as Energy Star, are increasingly becoming useful marketing tools for developers, with simple upgrades in building automation technology as an alternative. The technology is already available. $150 Funds devoted to a 10-year plan proposed by president-elect Barack obama for governmentled investment in clean-energy technology. Such a plan could compete directly with private sector investments. billion VoLuME 8 / IssuE 1 / 2009 52009-01-06T15:24:43+01:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=8http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=8Danfoss convenes industry players and lawmakers to discuss upcoming regulation and oversight Industry Readies Green Event, circa 1960: “Love your mother— Mother Earth! Come to the Quad tomorrow at noon to rally for the environment and against the politicians who poison our water and pollute our air. BYoB.” a Green Event, Today: “on november 14, more than 40 business leaders, eminent researchers, financiers, and policy makers convened at La Costa Resort in Carlsbad, Ca for the danfoss EnVisioneering symposium to discuss conservation themes including pending legislation involving climate change and energy efficiency.” The 60s rally is historical fiction. The EnVisioneering symposium is an accomplished fact. washington is the vortex of important domestic issues, and energy efficiency is a focus on Capitol Hill. This was apparent at the danfoss EnVisioneering symposium on Climate Change in Carlsbad, where a large portion of the discussion centered on climate change and energy efficiency legislation that may take hold with a new Congress and administration set to take over in January. FoR 2009 WHITE HoUSE a In particular, panelists agreed that climate change bills that are currently in Congress would, if passed, significantly increase energy efficiency demands and dramatically reduce the use of HfC refrigerants, an issue of critical importance to the HVaC&R industry. with President-elect obama’s emphasis on energy, energy security and “green” jobs, Kevin fay, president of government relations firm alcalde & fay, projected at the symposium that lawmakers will pass new regulations or modernize existing policy that has outlived its usefulness. This, he said, would include climate change legislation, although he projected such policy isn’t likely to pass before late 2009 or 2010. The 2008 bills, he added, had common approaches that could become the foundation for new legislation in the next Congress. david McIntosh, former counsel and legislative assistant for energy and the environment for sen. Joseph Lieberman, Id-Conn., said he expects legislation to affect the HVaC&R industry and mandate a phase-down of HfC refrigerants. He noted that each bill authored by Congress recognized the important roles that these refrigerants play in today’s high-efficiency air conditioning and refrigeration equipment. McIntosh projected that future energy legislation could include mandates for new energy efficiency standards, as well as subsidies and tax incentives. The Congress and administration could look to state initiatives as possible models for legislation, as well as past federal initiatives. He also expects that the obama administration would enunciate a basic plan for climate change, outlining fundamental principles such as “cap and trade,” targets and timetables, and affixing each to a specific industry segment such as transportation, utilities, and HVaC&R. with such an outline, he said, Congress could begin work on specific portions of the agenda, without having to write a single comprehensive bill covering all aspects. at times, planners should look at energy regulation from this policy-making perspective in order to adequately prepare for likely regulation. Two committees—the senate Environment and Public works Committee and the House Energy and Commerce Committee—produced bills in 2008, and McIntosh said he expects the financial dimensions of the climate change issue to draw the House ways and Means Committee and the senate finance Committee into the issue. He also predicted senior staff from the Environmental Protection agency and the department of Energy would also recommend input to legislation. He urged the HVaC&R industry to closely follow the proceedings of these committees and agencies. Because of the changing of the guard in washington, 2009 will undoubtedly be a big year for energy efficiency policymaking and planning, and every indication points toward more regulation or oversight of how energy is created, supplied, used, and pri2009-01-06T15:24:43+01:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=9http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=9Global Energy Policy When seeking to complement the private sector in producing energy efficiency technologies for mainstream use, United States regulators and lawmakers may very well look to the international community for cues. This is why when examining domestic energy situations, the contention that what goes on outside the United States has more impact than what goes on within its borders may have merit. One barometer for the energy discussion on a global scale is the Group of Eight, which meets annually to discuss international economic issues. The G8, traditionally more economically-focused than other NGOs, is perhaps in the best position to affect global energy trade. The G8, unfortunately, missed an opportunity to advance energy debates when it excluded China from its energy meetings earlier this year. Given China’s thirst for imported oil and its high level of carbon emissions, it isn’t possible to have a meaningful discussion about energy without their involvement. Despite the growth of China’s economy, it will remain a significant importer of oil for the foreseeable future. The G8’s energy actions will be telling. If it engages China in next year’s dialog about energy issues, then the global community, and the United States in particular, will benefit from a nongovernmental ally in shaping solutions to global energy challenges. If it fails to engage China or excludes other emerging and influential nations, then it risks not advancing truly global energy solutions. Given its authority and its stated goal to address global energy dilemmas, the G8 should take any opportunity to engage all significant importers and exporters in dialog about these issues and to push global leaders toward alternative energy solutions. Neither the public nor the private sector alone will produce meaningful progress toward reducing energy consumption. What is vitally important is that both work together to understand the issues and ensure that sound energy policy begins now and continues apace as the economy rebounds. Given its authority and its stated goal to address global energy dilemmas, the G8 should take any opportunity to engage all significant importers and exporters in dialog about these issues and to push global leaders toward alternative energy solutions. The group of eight: France United States United Kingdom Russia Germany Japan Italy Canada Known as the G8, this international organization holds the most potential for affecting global energy trade. A key to its success in next year’s dialog is the engagement of China, a nation currently paying little heed to environmental concerns such as oil consumption.

For example, the LEED Green Building Rating System™ is a nationally recognized benchmark for the design, construction, and operation of high-performance green buildings. The USGBC is modifying its LEED standards, reorganizing the commercial rating systems by consolidating, aligning, and updating them into one system. A new version, called LEED 2009, will debut in January. » In California, the Public Utilities Commission adopted the state’s first Long-Term Energy Efficiency Strategic Plan. The plan has four main strategies: achieve zero net energy in all new residential construction by 2020; realize zero net energy in all new commercial construction by 2030; reshape the HVAC industry to ensure optimal equipment performance; and attain energy efficiency in all eligible low-income homes by 2020. » The Chicago city government unveiled its climate change plan in September. Under the plan, the city will work to reduce greenhouse gas emissions to 25 percent below 1990 levels. Other U.S. cities have set similar goals, but Chicago’s plan is the first to both research emission sources and anticipated impacts while proposing ideas that specifically respond to that research. » on the legislative front, President Bush signed the Emergency Economic Stabilization Act of 2008 in early October. The new law contains extensions to both current and expired tax incentives for renewable energy, energy-efficient building upgrades, and appliance and equipment purchases. A key provision is the extension of the Commercial Building Tax Deduction through 2013. This will allow building owners to claim a deduction up to $1.80 per square foot for HVAC, lighting and envelope upgrades resulting in 50 percent energy savings over ANSI/ASHRAE/ IENSA Standard 90.1-2001. “Energy and the environment are, and will continue to be, key focuses for governments around the globe,” noted Robert Wilkins, president of Danfoss North America. “The engineering and HVAC&R communities must continue to be open to new ideas and initiatives, and to embrace changes that will make the world a better place to live, work, and play, while creating profitable business opportunities.” “The engineering and HVAC&R communities must continue to be open to new ideas and initiatives, and to embrace changes that will make the world a better place to live, work, and play, while creating profitable business opportunities.” — Robert Wilkins, president of Danfoss North America VoLuME 8 / IssuE 1 / 2009 92009-01-06T15:24:43+01:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=12http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=12CasE sTudY T wo d a n f o s s V LT ® a Q u a d R I V E » pumps water at 70 PsI; flow rate of 760 GPM » can be used not only as the fire suppression system, but for plant processes as well » compact and does not rely on external drives » saves customer upwards of $70,000 Supply And Save Costs, Improve Efficiency d u R I n G T H E Y E a R s , sprinkler systems have saved lives and property that otherwise may have fallen victim to fires. While this risk reduction can clearly be a worthwhile investment, the level of complexity in setting up these systems can vary. In most cases, it is a relatively simple process to connect the sprinkler system to the municipal water supply, which ensures an acceptable flow rate and static pressure. In rural areas where the municipal water supply is inaccessible, however, the process can be decidedly more rigorous. The Central Lakes Cooperative fertilizer plant in Atwater, Minnesota, is an example of the latter. At 12,000 square feet, the facility was required to install a sprinkler system according to Minnesota State fire code. However, being too far from the municipal water supply, the system would have to be served by a well. CLC looked to Mike Steffl of Steffl Drilling and Pump to drill the well and provide the necessary components to meet the requirements of the fire code. The typical solution in this case required installing a submersible pump and a 100,000-gallon reservoir to ensure adequate water capacity for the system. This reservoir would not only require a large excavation and a significant amount of concrete, but would take up a lot of space as well. Steffl and another contractor, Brian Peterson of Schwab, Vollhaber and Lubratt, Inc., looked at their options and saw that they could work out a better solution by using AqUA SToRIES: Integrate Sprinkler Systems To Daily Water 10 EnVIsIonEERInG soLuTIons2009-01-06T15:24:43+01:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=13http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=13variable frequency drives. Working closely with the state’s fire marshall and electrical inspector, they were able to implement an innovative solution that was far more costeffective, reliable, and compact than the traditional alternative. In the CLC plant, the sprinkler system is pressurized with air to protect against the cold Minnesota winters. An air pressure transducer monitors the system. When the air pressure drops suddenly, indicating that one or more of the sprinkler heads have been triggered by a high heat condition, a relay is tripped, and a 75 HP Danfoss VLT AQUA drive connected to the system switches from its “normal” parameter setup to another setup that is specified for fire mode. The drive runs a submersible pump located in the well, which pumps water into the sprinkler system at 70 PSI with a flow rate of 760 GPM. One of the advantages of this configuration is that the drive and submersible pump can serve not only the fire suppression system, but can be used for plant processes as well, since both systems of pipes are interconnected. Under normal operating conditions, the drive runs the pump to supply the plant’s water piping with 20 PSI and a flow rate of 200 GPM. If a fire breaks out, a valve closes to isolate the regular water piping from the higher pressures required for the fire suppression system. The variable frequency drive provides motor protection at both points of the pump curve: at the lower, normal operating condition as well as the higher demands of fire mode operation. “All of the intelligence is built into the drive, rather than relying on external devices,” said Peterson, “which makes for a very compact system.” Normally, a dedicated pump connected to a fire suppression system would require regular testing to ensure that it would still be operable when needed. The system at CLC sidesteps this requirement because the pump is run on a regular basis, supplying water used to fill spray tanks and other purposes throughout the plant. In this way, the system is also more reliable, since operating the pump keeps the seals lubricated and ensures that the shaft doesn’t lock up from disuse. The solution at CLC also enjoys other advantages over the traditional solution. A reservoir, in addition to posing extra costs and longer installation time, would present the problem of stagnant water. A fire suppression system might go years or even decades before being needed. If not maintained, water that sits for this period of time can become contaminated to the point that it would clog the system when it is finally called for. To prevent this, chemicals can be added to the reservoir, but this typically requires a confined entry access point and multiple personnel with the proper certifications and breathing apparatus. Because the system at CLC is also used for day-to-day purposes, there is no danger of stagnant water clogging the system, and therefore none of the associated maintenance requirements. The installation is one of the first of its kind, but with a cost savings to the customer of more than $70,000, it’s expected that many more like it will follow. Both Peterson and Steffl are working with other partners and the Minnesota state fire marshall to amend the state’s fire code to recognize this technique as a reliable and effective system for fire suppression. Steffl said, “it’s important to not only have the technology that makes solutions like this possible, but also that you have the people on your team with the knowledge and expertise to be able to make it happen.” The installation is one of the first of its kind, but with a cost savings to the customer of more than $70,000, it’s expected that many more like it will follow.

A CASE STUDY IN CUSToMIzATIoN L o n G I s L a n d w I n T E R s a R E , in a single word, brutal. It’s often warm in the sun and cold in the shade. The wind blows so hard that buildings seem to move. If a heating system isn’t up to par, indoor temperature conditions are about as reliable as next week’s weather: not at all. The Church of the Holy Name of Mary is a religious complex that rests on several acres of land right off the Long Island Railroad in Valley Stream, New York. Its rectory houses about 20 staff members who support the church next door or the school across the street. For years, the occupants have grappled with an outdated heating system that had a 1960s-era boiler funneling heat to the building through centralized controls. 12 EnVIsIonEERInG soLuTIons Holy Name of St. Mary Church: This caused problems: the small rooms along the outer edges of the building fell victim to either direct sunlight or freezing wind during the wintertime, rendering the central heating controls meaningless. This compounded the socalled “meter wars” that usually arise when a central system manages comfort levels for a group of building occupants. When occupants furnish small offices with portable heating units, electricity bills go up and existing infrastructure isn’t used effectively. This often happened in the rectory. “The place used to be like an ice box,” Jerry Viola, head installer at OSI Comfort Specialists, noted. The church hired OSI to replace the outdated system with a more-customized and efficient solution.2009-01-06T15:24:43+01:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=15http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol8Issue1/?Page=15“There was such a difference in comfort requirements among the residents. One would be too warm, and another too cold. It really ran the gamut and was a notably stark contrast from one resident to the next,” Viola added. “On top of the cost, this was making everyone uncomfortable and less productive.” Small rooms and offices, many around 120 square feet, amplified the inefficiency of the central control that wasn’t nimble enough to heat small spaces and large spaces with equal effectiveness. OSI replaced the two boilers from the 1960s with newer, efficient models and installed thermostatic radiator valves into every room. This solved the problems that the centralized control was causing and gave occupants control of the temperature in their live-in offices. This approach also rendered externalities like the force of chilly Long Island winds and the direction of the sun meaningless. The self-contained system required very little piping work because the necessary pipe-work was already present throughout the building’s many small offices. The installation team, which also included Richard and Martin Levi, principals at OSI, also used industrial innovations like ball valves and crimp fittings on the boiler to manage heatflow and reduce manual work like soldering parts together. These technologies will make the unit easier to service down the road. The thermostatic controls and in-room valves, hidden by radiator covers, represented most of the installation work, said Viola, and create most of the benefits. The residents see the thermostat on the wall and know they have unabashed control over the temperature, he said. “The Danfoss equipment has consistently proven that it does what it’s supposed to do,” Viola added. The new system achieved marginal cost savings while delivering the real value: the improved comfort level of the building’s occupants. “The residents are delighted with the system’s controllability and response, and the building has never been more comfortable for its residents. Many projects like this produce measurable cost savings, but for Holy Name of Mary, the intent was to create value by enabling a great level of control over their environment, since a lack of control was the core problem. “Every piece of feedback, anecdotal or otherwise, says that it worked,” he concluded. October 2008 marked one year since OSI installed the new system, with support from Wallace Eannace Associates and supplies from Danfoss. Currently, Holy Name of Mary is reviewing options for upgrading the heating system in the three other buildings that comprise it: a convent, a school, and a church. All three pose unique challenges and will need similar customized solutions, Viola said, which would include Danfossengineered components. This project illustrates one axiom in facility design and management: Buildings that fail to account for occupant comfort levels and instead rely on centralized systems are usually wasting energy, not conserving it. And the availability of customized, practical components makes upgrade projects quick and sustainable. The thermostatic controls and inroom valves, hidden by radiator covers, represented most of the installation work… and create most of the benefits.
