Boosting Energy Performance in Federal Facilities

Buildings Magazine, Nov. 2014, by Chris Olson.
http://www.buildings.com/article-details/articleid/18131/title/boosting-energy-performance-in-federal-facilities.aspx

"The federal government manages some 429,000 buildings totaling 3.34 billion square feet. It owns approximately 80% of that space and leases 20%. A portfolio of that mammoth size clearly has an impact on the buildings industry. The Bush and Obama administrations have established a number of targets for facility energy use. GSA,DOE and other federal agencies are developing a variety of approaches, including performance contracting, deep retrofits, a green “proving ground,” and analytics tools. The private sector can learn from the government’s successes."

Avista’s Aging Headquarters Gets Energy-Efficiency update

The Spokesman-Review, Dec. 12, 2014, by Becky Kramer.

"When the heating-and-cooling system at the Spokane utility’s corporate headquarters passed the half-century mark a few years ago, officials decided it was time for replacement.

The new system is part of a $28 million energy-efficiency remodel that will eventually cut power costs at the utility’s headquarters on Mission Avenue by $275,000 per year. The updates will save about 2.8 million kilowatt hours of electricity annually, or enough to power 233 homes."

Compressed Air Supply at a Metal Machining Plant

Compressed Air Best Practices, Nov. 2014, by Don van Ormer.

"This metal fabrication and machining facility produces high-quality precision-built products. Over the years, the plant has grown and there have been several expansions to the current location. The company currently spends $227,043 annually on energy to operate the compressed air system....The set of projects recommended, as a result of the system assessment, could reduce these energy costs by $89,092 or 39%."

Northwest Public Utilities, BPA Top Five-Year Energy Savings Target

Bonneville Power Administration Newsroom, Nov. 25, 2014.
http://www.bpa.gov/news/newsroom/Pages/Northwest-public-utilities-BPA-top-five-year-energy-savings-target.aspx

"Since 2010, Northwest publicly owned electric utilities and the Bonneville Power Administration have saved at least 560 average megawatts of electricity, greatly surpassing the five-year goal of 504 aMW set by the Northwest Power and Conservation Council’s Sixth Power Plan."

Improve [Refrigeration] Efficiencies With Careful Compressor Selection

Heating, Plumbing, Air Conditioning, Oct. 2014, by Autumn Nicholson and Mike Saunders.

"[Commercial] Refrigeration system designers have traditionally selected compressors to match the capacity anticipated on the hottest days of the year, accounting for a design Btu load and high ambient temperatures. While this approach ensures required performance in extreme conditions, it does not always equate to achieving system efficiencies. In light of the changing refrigeration landscape, designers should evaluate compressor selection on three important considerations.


Estimating Customer Electricity Savings from Projects Installed by the U.S. ESCO industry

Lawrence Berkeley National Laboratory, Nov. 25, 2014.
http://emp.lbl.gov/sites/all/files/Estimating%20customer%20Electricity%20Savings_25Nov2014_FINAL.pdf

"We introduce a method to estimate the total amount of electricity saved by projects implemented by the U.S. ESCO industry using the Lawrence Berkeley National Laboratory (LBNL) /National Association of Energy Service Companies (NAESCO) database of projects and LBNL’s biannual industry survey. We report two metrics: incremental electricity savings metric and savings from ESCO projects that are active in a given year (e.g., 2012)."

"An updated take on a technology is helping designers make buildings more comfortable and energy efficient while adhering to cleaner aesthetic."

Watts in a Drop of Water: Savings at the Water-Energy Nexus

ACEEE White Paper, Nov. 5, 2014, by Rachel Young. [Free registration required to view full-text.]
http://aceee.org/white-paper/watts-in-drop-water

"This paper shows a range of energy intensities for water and wastewater services and in residential hot and cold water. We draw from existing data to develop national estimates of energy savings associated with water savings, including energy used in water conveyance, water heating, and water and sewage treatment."

"Green sports facilities set an example for other sites." Sustainability & energy efficiency highlights are given for seven stadiums.

A Tale of a Poorly Designed [Incentive] Program and Overly Judgmental Evaluators

ACEEE Blog, Nov. 4, 2014, by Steven Nadel.
http://aceee.org/blog/2014/11/tale-poorly-designed-program-and-over

"The E2e project released a working paper recently that evaluates the State Energy Efficient Appliance Rebate Program (SEEARP), funded in 2009 by the American Recovery and Reinvestment Act. In the paper, authors Sebastien Houde and Joseph Aldy find that the SEEARP program provided little economic stimulation or energy savings."
