Energy Newsbriefs Blog

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.

 


Net Positive Energy Buildings

ASHRAE Journal, Aug. 2016, by Dylan Connelly and Laura Fedoruk. (Article Summary only.)
https://www.ashrae.org/resources--publications/periodicals/ashrae-journal/features/net-positive-energy-building

"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects."

"Have you ever described efficiency as an energy resource and gotten a quizzical look in return? We have, even though utility system planners have been using energy efficiency for decades to make sure that power for their customers is both reliable and affordable. For those of us who have been in the energy efficiency industry for years, or even decades, we sometimes take for granted that others will understand what we mean. But we must not."

Proving its Long-Term Mettle: Longevity, Whole-Building LCAs, and Stainless Steel

The Construction Specifier, Aug. 2016, by Catherine Houska.

"Whether the project is a new building or major renovation, sustainability is an increasingly important factor in decision-making. Whole-building life cycle assessment (LCA) makes it possible to look at all phases of a building, from material extraction through construction to decommissioning and, when possible, recycling into a ‘new’ useful material. When it comes to comparing materials, increasingly available data, an ASTM standard procedure, and LCA analysis software are helping design professionals make better choices to reduce the building’s carbon footprint."

Optimizing Lubrication [Wind Turbines]

Wind Systems, Aug. 2016, by Jesse Dilk and Jestin Hulegaard, Klüber Lubrication.
http://www.windsystemsmag.com/article/detail/1262/optimizing-lubrication

"Since each rolling bearing in a wind turbine operates under different conditions, it often is assumed using a variety of lubricants is essential for serving all of them. For operators, this means not only added logistical efforts and expensive warehousing but also the increased risk of product mix-ups. Some newly developed greases can be used for all rolling bearings in a wind turbine."

Update on U.S. Fan Energy-Efficiency Regulation

Heating, Piping, Air Conditioning Engineering, Aug. 2016, by Anthony (Tony) Rossi and Michael Wolf.

Premium Power Drive Systems

Heating, Piping, Air Conditioning Engineering, Aug. 2016, by Rob Boteler.
http://hpac.com/motors-drives/premium-power-drive-systems

"Increasingly in industrial and commercial HVAC applications, electric motors are being combined with power converters to form premium power drive systems (PPDS). When used in variable-flow applications, PPDS can deliver savings unmatched by mechanical speed/flow-control systems."

Mobile Homes Move Toward Efficiency

ACEEE Blog, Aug. 3, 2016, by Lowell Ungar.
http://aceee.org/blog/2016/08/mobile-homes-move-toward-efficiency

"Do you know which government in the United States is the biggest laggard on energy codes for homes? The federal government. But that’s about to change. -- Manufactured homes and the “HUD Code”."
