This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


Six Factors to Assess Green Roofs

Buildings Magazine, Feb. 2015, by Jim Kirby.
http://www.buildings.com/article-details/articleid/18496/title/6-factors-to-assess-green-roofs.aspx

"Through its lifecycle, a roof has a variety of environmental impacts. However, many impacts can be controlled by building owners and facility managers, resulting in lower energy costs and longer service life. Take control of these factors to curtail environmental impacts and reduce energy and lifecycle costs on all roofs."

Case Study: Portland Community College Newberg Center: Newberg, Ore.

High Performance Buildings, Winter 2015, by Doug Reimer and John McMichael.
http://ww.hpbmagazine.org/File%20Library/Case%20Studies/Winter%202015/15W-Portland-Community-College-Newberg-Center-Newberg-Oregon.pdf

"As the first building on what could potentially become an entirely net zero energy campus, the Portland Community College (PCC) Newberg Center represents a pioneering model for higher education institutions. Sustainable features are integrated building blocks of the design rather than attachments."

"Emissions control and energy use improvements have won a Washington film extruder and converter $342,000 worth of incentives as a state of Washington energy leadership-in-innovation award. Shields Bag and Printing Co. installed a regenerative thermal oxidizer (RTO) and a flexographic press to improve production at its Yakima, Wash., facility."

Industry Prepares for New Residential Water Heater Standards

Air Conditioning, Heating & Refrigeration News, Feb. 9, 2015, by Jen Anesi.

"New minimum energy-efficiency standards go into effect for nearly all residential gas and electric water heaters on April 16, 2015. The set of rigorous rules are the third generation of standards the U.S. Department of Energy (DOE) has issued for the equipment under the National Appliance Energy Conservation Act of 1987 (NAECA). While the new efficiency standards do not require manufacturers to use any specific technologies to achieve the new EF (energy factor) ratings, they’ve already necessitated a significant redesign effort from manufacturers."

Faulty Installations Slash System Efficiency [HVAC Equipment]

Air Conditioning, Heating, Refrigeration News, Feb. 9, 2015, by Nicole Krawcke.
http://www.achrnews.com/articles/128787-faulty-installations-slash-system-efficiency

"Duct leakage, refrigerant undercharge or overcharge, low indoor airflow, and oversized equipment with undersized ductwork have the most potential to significantly degrade equipment efficiency, according to a recent National Institute of Standards and Technology (NIST) study. Contractors who adequately address these challenges differentiate themselves from the competition."

New Incubator Network to Help Clean-Energy Entrepreneurs

National Renewable Energy Laboratory (NREL) News Release, Feb. 4, 2015.
http://www.nrel.gov/news/press/2015/16455.html

"The Energy Department's National Renewable Energy Laboratory (NREL) and the Electric Power Research Institute (EPRI) have launched the Clean Energy Incubator Network. The program, funded by the Energy Department, aims to improve the performance of clean energy business incubators, connect critical industry and energy sector partners, and advance clean energy technologies emerging from universities and federal laboratories."

Chilled Water Thermal Energy Storage [TES] Hydraulics

ASHRAE Journal, Feb. 2015, by Kent W. Peterson.

"Chilled water thermal storage can provide many energy cost benefits when implemented in chilled water systems. Placing an atmospheric chilled water thermal energy storage tank in a chilled water system will have several engineering ramifications on the hydraulic performance of the system. Understanding these hydraulic implications and designing the optimum solutions for addressing these implications will improve both control and energy performance."


Part One: Radiant Heating and Cooling Systems

County [King County, WA] Trials Energy Tracking Software Used by Microsoft

Energy Manager Today, Mar. 3, 2015, by Linda Hardesty.
http://www.energymanagertoday.com/county-trials-energy-tracking-software-used-microsoft-0109722/

"King County, Washington, plans to pilot the same energy-tracking software that Microsoft uses to reduce energy consumption at many of its buildings. Seattle-based design firm MacDonald-Miller will install the software at five King County facilities for the two-year pilot project. Iconics developed the software using Microsoft’s cloud-based Azure platform."
