Infographic – Energy efficiency. A solution.

Duane Tilden‘s insight:

Industry has been reported to consume between 40 and 60% (UN Report) of the world’s electrical supply.  Motors are the largest consumer of the industrial electrical supply and the greatest opportunity for industry wide savings.

Many motors are over-sized and run inefficiently.  Variable speed drives can significantly reduce industrial operating costs, with attractive payback period and reductions in energy consumption by up to 50% or more.

The 10 Most Energy-Efficient U.S. States: The Forgotten ‘Fifth Fuel’

See on Scoop.itGreen & Sustainable News

Access to energy in the U.S. — and the effects of generating it — are a national concern.

Duane Tilden‘s insight:

>The Forgotten ‘Fifth Fuel’

Access to energy in the U.S. — and the effects of generating it — are a national concern. Debates persist over the most cost-effective and environmentally friendly mix of nuclear energy, coal, gas and liquid hydrocarbons and renewable sources.

Too often left out of these discussions is the so-called fifth fuel: energy efficiency. States have driven benefits for consumers and the environment with policies that both reduce energy use and encourage economic growth.

The American Council for an Energy-Efficient Economy (ACEEE) yesterday issued its annual scorecard for each state based on multiple factors, including reductions in greenhouse gas, energy codes for buildings and switching to cleaner fuels.<

How Real Estate Energy Managers Can Use Big Data to Schedule Building Energy Retrofits

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

Big Data remains a fairly nebulous concept for many real estate professionals, including those who stand to gain tremendously from it right now: real estate energy managers.

Duane Tilden‘s insight:

>To effectively time energy retrofit measures, energy managers can first develop those measures. New energy analytical tools such as FirstFuel identify and develop measures, and even estimate a range for capital cost. It does this analysis remotely over the course of a day just by analyzing hourly electricity data (which is sometimes also stored by the utility); no time-intensive on-site energy audit is required. Another new tool is Retroficiency, which provides a high-level look at energy performance improvement potential using the same interval data and, with minimal additional data from the IWMS, can further develop retrofit measures to investment-grade level.

After identifying energy-retrofit measures for the portfolio using remote energy analysis tools or more standard on-site energy analysis, energy managers can create a new retrofit measures database in the IWMS. Having this new database on hand enables managers to integrate energy retrofit opportunities with space management, maintenance and capital upgrade needs, and potentially other real estate issues. Such integration drives down the incremental cost of an energy retrofit, which is the gross cost minus the avoided cost of otherwise required capital or space upgrades.<

Kyocera Opens Japan’s Largest Offshore Solar Power Plant

See on Scoop.itGreen & Sustainable News

The Kyocera Corporation just opened a 70 megawatt solar power plants off the southern coast of Japan.

Duane Tilden‘s insight:

>Kyocera partnered with six other companies to develop the solar plant, which is located in the Kagoshima Prefecture. The company hopes that this latest offshore venture will set a precedent for a cleaner Japan, especially in light of the 2011 Fukushima disaster. The solar plant is designed to inspire and encourage Japan to make the switch to more renewable energy sources.

The Kagoshima Nanatsujima Solar Power Plant was made possible in part because of Japan’s revised feed-in-tariff (FIT) program, which was restructured in July, 2012 to better accommodate solar energy. The adjusted FIT plan requires local utilities to purchase 100 percent of the power generated by solar plants that produce more than 10 kW.<

Lessons in Energy Saving, a guest blog by Roger Hunt

>The energy saving measures are being retrofitted during a wider refurbishment project. They range from secondary glazing, draught-proofing and new energy efficient boilers to roof insulation, LED lighting and the installation of wood burning stoves. There are also low volume baths, dual flush cisterns and heat recovery systems in the bathrooms. Full details of the Buscot and Coleshill refurbishments and a short video can be found at the SuperHomes website.<

National Trust Places


If you live in an old house and you’re worrying about your fuel bills you’re not alone. The National Trust has also been thinking about how it can cut its energy costs and is keen to share its ideas and experiences. But what, you may ask, does your home have to do with the Trust’s grand houses that we flock to see? Maybe not much. That’s why the lessons it’s keen to pass on are from its ‘estate’ of some 5,000 much more ordinary properties that it lets out and which it’s upgrading and retrofitting to be more energy efficient.

Crucially, most of these buildings have solid walls so they fall into what’s often referred to as the ‘hard to treat’ category. They also have those ingredients beloved by estate agents: ‘character’ and ‘period features’. In other words they’re often exactly the same sort of property that you and…

84% Efficient Combined Heat & Power (CHP) Plant to be built by Siemens in Poland

See on Scoop.itGreen & Sustainable News

Through immediate publication of press releases, we keep the business, financial and public press informed on all important Siemens topics.

Duane Tilden‘s insight:

>The plant will be built in western Poland in the city of Gorzów Wielkopolski. Within the scope of turnkey construction, Siemens will deliver two SGT-800 gas turbines, one SST-400 steam turbine, three 11 kilovolt (kV) generators and two heat recovery steam generators. In addition, Siemens was awarded a long-term 12 years maintenance agreement for the gas turbines. The Gorzów plant will be fired with nitrogen-rich natural gas from gas reserves located in western Poland. This type of gas has a lower calorific value than conventional natural gas. […]

The Gorzów power plant will replace a currently used coal-fired block at the same location. The combined cycle power plant with district heat extraction will be able to generate electricity in a much more efficient and environmentally friendly manner. Compared to the old coal-fired power plant, the new plant will produce 95 percent less sulfur dioxide emissions, more than 30 percent less nitrogen dioxide emissions and more than 95 percent less particulate emissions.<

The Future of Green Building Codes

>However, as buildings get more and more efficient, elements such as building operation and occupant use make up a bigger slice of the building performance pie.

Even for buildings that commit to stringent building standards, there’s a large range of outcomes, Frankel says, as to how those buildings eventually perform based on factors that currently are almost entirely outside the purview of the building code.

For example, in a recently retrofitted office building engineered for high performance that Frankel profiled, plug loads made up nearly half of all the energy the building consumed. “That has nothing to do with code, and it doesn’t even have that much to do with operation,” Frankel said. “It has to do with the occupants.”

As a result, it’s these areas—operation and tenant behavior—that are going to see most of the action in code policy discussion in coming years, he says.

“We have to find a way to engage operators and occupants in this discussion,” he says, “or we are never getting to net zero.”<

The Knowledge Builder

In many discussions of building performance, it’s builders and architects that are forced to take all the heat for buildings’ carbon footprints. But that wasn’t true of a recent presentation given by Mark Frankel, technical director of the Vancouver, Wa.–based New Buildings Institute, titled “Codes Standards and Rating Systems,” delivered at the recent Vision 2020 Sustainability Summit in Washington, D.C. While Frankel noted that there’s certainly more that can be done in design and construction to improve how a building will perform, “there’s not as much room left in building design as we’ve already captured,” he said.

That’s not to say there’s not still a long way to go. In the United States, the building sector is still the highest contributor to greenhouse gasses. And many builders and architects have yet to fully embrace the high-performance building practices that Frankel emphasized are available. “We have the technology…

Clean Energy rebranded by DOE to Combined Heat and Power (CHP)

See on Scoop.itGreen Energy Technologies & Development

In a move that had been in the works for a while, the U.S. Department of Energy recently announced that its Clean Energy Application Centers have been rebranded as CHP Technical Assistance Partnerships, or CHP TAPs.

Duane Tilden‘s insight:

>The CHP TAPs maintain the same regional offices that existed under the former Clean Energy Application Centers:

  1. Pacific (California, Nevada);
  2. Southwest (Arizona, Colorado, New Mexico, Oklahoma, Texas, Utah, Wyoming);
  3. Northwest (Idaho, Montana, Oregon, Washington);
  4. Midwest (Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota);
  5. Southeast (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee);
  6. Mid-Atlantic (Delaware, Maryland, New Jersey, Pennsylvania, Virginia, West Virginia); and
  7. Northeast (Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, Vermont).

With the new energy in these programs, now is the time to take advantage of the expertise offered by the Department of Energy and its CHP TAPs. Industrial users, municipalities, hospitals, college campuses and other large users of energy need to review and understand the significant benefits of CHP, district energy and waste heat capture technologies.<

Connecticut Storm Proofing with Micro-Grid Developments

See on Scoop.itGreen Energy Technologies & Development

Press Release Gov. Dannel P. Malloy announced Oct. 30 that nine towns that are part of a pilot microgrid program, including Windham and Storrs, are eligible for additional funding.

Duane Tilden‘s insight:

>A pilot microgrid program, administered by the state Department of Energy and Environmental Protection, was created under Public Act 12-148 to increase the safety and quality of life for Connecticut residents during electric grid outage situations.

Microgrids provide electricity to critical facilities and town centers on a 24/7, daily basis. They will also include a system of “trips” and “transfers” to isolate the microgrid and provide power within its network even when there is a large-scale outage.

The first round of the program awarded $18 million in grants to microgrid projects in Bridgeport, Fairfield, Groton, Hartford, Middletown, Storrs/Mansfield, Windham and Woodbridge as part of the Governor’s Storm Legislation.

Those projects are expected to become operational over the course of the next 18 months, with the first projects slated to come online in early 2014. […]

“Our first-in-the-nation microgrid program is an essential tool to help minimize hardships to our residents and businesses when severe storms occur. We all know that it is not a question of if, but when the next super storm will strike, and it is essential we do everything we can to be prepared,” Gov. Malloy said.

Commenting on the additional funding, DEEP Commissioner Daniel C. Esty said, “It is essential to public safety that power be maintained to critical facilities and town centers even when the electric grid is down… Connecticut and the northeast continue to experience more severe and more frequent storms, so it is vital that the state aggressively pursues the development of microgrids statewide so that we are in a better position to provide critical services to the state’s residents and businesses.”<
