Define ‘green’ please

Describing a building as ‘green’ makes a lot of people cringe. The word is overused. And what does it mean exactly?

Serious efforts are underway to move away from the hype and offer a more specific analysis of a building’s energy performance. Think nutritional labels for food, except in kilowatt-hours instead of calories.

In fact, more than 50 national, regional and local governments have created policies to rate and disclose the energy efficiency of commercial buildings, according to the Institute for Market Transformation (IMT). They include the European Union, China, Australia and Brazil.

In the US, two states have such policies, California and Washington, as do five cities: Austin, Washington DC, New York City, San Francisco and Seattle.

These programs already place more than 60,000 buildings, totaling 4.1 billion square feet of floor space, under energy rating and disclosure rules. Meanwhile, Massachusetts is considering standards, as is the city of Portland, Oregon. And many more local and state governments are expected to follow. To help them, IMT this week published areport that details best practices in building labeling.

Why label buildings the way we do food? When a building has an energy performance label, buyers and sellers better understand its market value, IMT says.

“The premise mirrors transparency rules in other market sectors, such as nutritional labels on food and fuel economy ratings on vehicles, which are recognized around the world as consumer protections and keystones of free and fair enterprise,” says IMT, which is a Washington, D.C. group that seeks ways to overcome market failures in the energy efficiency industry.

While building labels may be a good idea, they are not always easy to create. For starters, property owners must be able to access data on how much energy their buildings consume. For large buildings, with many tenants, this can be difficult. Sometimes tenants have their own electric meters. Building owners must go to each tenant to seek the data, a cumbersome task at best. And some tenants may refuse to supply the information. Here utilities can help, says IMT, by agreeing to aggregate a building’s total energy use and supplying it to the owner (while keeping individual tenant data confidential).

In addition, once the building has a label, the information has to be simple for potential buyers to access. IMT recommends that states post the data on easy-to-navigate web sites that allow searches by address, benchmarking metrics, owner’s name, and traditional real estate characteristics, such as building size.

Two major approaches exist to rate buildings, says the report. Asset ratings “measure the structural energy performance of buildings based on simulated operating conditions.” Operational ratings, on the other hand, measure how much energy a building actually consumes. China tends to use asset ratings, while most US jurisdictions, so far, seem to prefer the operational approach.

How quickly will energy performance labeling catch on? It’s clearly become a hot topic, and the IMT report will help jurisdictions that want to move forward. Still, creating the rules is a state-by-state or even city-by-city effort, as is often the case when it comes to US energy policy. So we may be scratching our heads for awhile about what it means when we hear a building described as ‘green.’

Wanted: GOLD for smart grid

By Elisa Wood

April 8, 2010

As John McDonald tells it, smart grid needs GOLD. And he’s not talking money.

GOLD stands for Graduates of the Last Decade, the technology savvy, risk-taking engineers and technicians who may be among the greatest benefactors of the new smart grid movement. While most recent college graduates face dismal employment prospects, for the GOLD kids, the job market is, well, golden.

“I’ve never seen electric utilities and suppliers outbidding each other for a bachelor’s degree,” said McDonald, who has had 35 years in the energy business and now serves as an IEEE Fellow and general manager of marketing for GE Energy T&D.

GOLDs benefit from two converging trends. The first is the sizeable technical task that utilities face in integrating smart grid technologies. The second is the wave of retirements expected to hit the utility industry in the next five to seven years.

These young recruits will invigorate the utility industry, which is notorious for being risk adverse, a trait that has kept the lights on but also hinders adoption of new and more effective technologies.

Two utility cultures tend to dominate today, according to McDonald. One approaches smart grid with an “over my dead body” attitude. The second is about three retirements away from embracing smart grid.

“The older folks say we’ve been doing this for 20 years. I’ve got three years to retirement, and I’m not going to do anything new that might cause a problem,” he said. “That will go away with the GOLD folks. These are folks who went to Block Buster and rented a game and learned how to use it in a matter of minutes.”

Not only will GOLD engineers find it easy to get jobs in the electric power industry, but they also are likely to advance quickly in the ranks, McDonald said. Utilities have done little hiring in the last 15 years. Thus, the middle group – those in between upper management and new recruits – tends to be thin. So the way is clear for GOLDs to enter management early in their careers.

Demand for GOLDS is already strong, but it is likely to get even more intense. Smart grid is still new, only in the design/engineering phase, still to take on manufacturing and field deployment. More jobs will open as these stages occur.

What can engineering students do to position themselves for the plum jobs? McDonald advises that they pursue internships in the power and energy industry with electric utilities, testing labs and suppliers or snag research positions with professors. IEEE also has set up a website where job seekers can post resumes: http://www.ieee-pes.org/workforce/pes-careers.

“It is exciting for me because my son is in that [GOLD] space. The potential for him is much greater than it is for me,” McDonald said. “I’m 58. Most of us who have been in the industry for a long time will be more than willing to give decision-making to this group.”

Is green energy our new plastics industry?

By Elisa Wood

December 17, 2009

If The Graduate were written today, Mr. McGuire’s career tip to Benjamin probably would have been “green,” rather than “plastics.” But it’s likely Benjamin would have responded in the same quizzical way: “Just how do you mean that, sir?”

It was difficult to envision the vast number of new products, businesses and careers that would emerge from the plastics industry following World War II. The same is true for the green energy industry today. A report issued December 16 by PricewaterhouseCoopers sheds some light.http://www.pwc.com/us/cleantechrevolution

To know where the business opportunities will be, watch the unusual alliances forming among industries, according to “Cleantech Revolution: Building Smart Infrastructures.” We see hints already as automakers, utilities, battery makers and communications providers ally in preparation for an expected $165 billion smart grid build-out. The report cites several examples, among them:

• Nissan’s partnership with San Diego Gas & Electric to build electric vehicle charging stations
• Echelon and T-Mobile’s deal to create wireless networks connecting utilities to smart meters
• Cisco assisting Duke Energy in building a smart grid

“As the build-out gains traction, it has the potential to support a proliferation of new businesses across sectors, much like the evolution of both the semiconductor industry and the Internet,” says Tim Carey, PWC U.S. clean technology leader.

Don’t be surprised, says the report, to see a national retail store chain partner with an electric battery maker to install charging stations nationwide for plug-in electric vehicles. A new wave of corporate mergers and acquisitions also could be in the cards. The opportunities are vast, especially when you consider the size of the smart grid. The US has 160 million households awaiting installation of smart meters. These new devices will require changes in the way we operate our electrical infrastructure, which encompasses 3,100 utilities, 10,000 power plants, 5,600 distributed energy facilities and 157,000 miles of high voltage transmission wires, says the report. How many better mousetraps can a system of this size support? More than we can imagine.

The clean technology, boom, however, depends heavily on consumer acceptance. If consumers find smart meters too complicated or plug-in hybrids unreliable, the game is over. To avoid this problem, organizations like the American Council for an Energy Efficient Economy are focusing on understanding customer motivation.http://www.aceee.org/conf/09becc/09beccindex.htm.

Use of smart grid technologies must become “pervasive and ingrained,” says the PWC report. Sunil Sharan, of the Center for American Progress, sees the smart meter becoming like the Blackberry, “with all sorts of applications.” Indeed, energy industry insiders often describe the next game changer – whatever it will be – as the cell phone of energy. But given how integral electricity is to our everyday lives, clean technologies need to become everyman products. Out of the corporate alliances, the mergers, the breakthroughs and the investment deals, maybe it’s not energy’s cell phone that will make fortunes, but its plastic wrap.

Reality check: Is green arrogant?

By Elisa Wood

June 25, 2009

During a recent interview, a utility executive used the phrase “the arrogance of renewable energy.” He was talking about the need to keep costs in check and implying that green energy businesses do not.

The executive asked that I not attach his name to the phrase. He was afraid he would anger those in the renewable energy world with whom he does business. Not so long ago, utilities publicly criticized renewable energy without a second thought. His reticence to do so underscored to me just how powerful the green energy movement has become in the United States. From town councilors up to the US President, the political official is rare who does not back green energy.

To quote FDR, with power comes responsibility. In a world where green energy is receiving unprecedented public funds, the industry needs to ensure that public money is not squandered.

For energy efficiency, this means accurate measurement of savings, particularly in performance contracting. No fudging. Fortunately, the IT world increasingly offers technology that can pinpoint with accuracy if energy efficient motors, fans, lighting and other equipment lives up to its promise. http://www.onsetcomp.com/resources/white_papers.

Equally important, organizations like ASHRAE and the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) are looking for more meaningful ways to quantify energy savings.

Green designs that work in theory do not always work in practice. An empty building does always behave the same way as a building with people filling the space. That is why the US Green Building Council plans to require operational performance data on a recurring basis as a precondition for LEED certification. http://www.usgbc.org/Docs/News/MPRs%200609.pdf

“Today there is all too often a disconnect, or performance gap, between the energy modeling done during the design phase and what actually happens during daily operation after the building is constructed,” said Scot Horst, senior vice president of LEED, U.S. Green Building Council. “We’re convinced that ongoing monitoring and reporting of data is the single best way to drive higher building performance because it will bring to light external issues such as occupant behavior or unanticipated building usage patterns, all key factors that influence performance.”

Horst added: “Similar to the sticker on a new car that says the car will get 30 miles to the gallon — the car is calibrated to perform, but it’s also reliant on the driver’s habits.”

Meanwhile, ASHRAE is working on a prototype label, or “Building EQ” that measures energy use in a building in two ways. A new building initially receives an asset rating, based on its design. After its performance is monitored for a year and data is collected on actual energy use, the building becomes eligible for an operational rating http://www.ashrae.org/pressroom/detail/17194.

“When potential building tenants and owners have information on the properties they are interested in, they can understand the full cost of their investment and place a value on the energy efficiency of a building. ASHRAE’s label will help building owners differentiate their product in a technically sound manner while providing tenants with the tools they need to select energy-efficient spaces,” said Ron Jarnagin, who chairs the committee developing the label.

Accurate measuring and monitoring increasingly seems to be the name of the game in a world where use of public funds demands accountability. Performance labels are a far better alternative for the green energy world than labels of arrogance.
