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.

"After decades of the old terminal velocity standby, it may be time to do away with “We’ve always done it that way.”"

Codes and Standards For Energy Conservation

The Construction Specifier, Mar. 2017, by Anthony Katona.
https://www.constructionspecifier.com/codes-and-standards-for-energy-conservation/

"Concerns with global warming and energy consumption mean design/construction professionals need a better understanding of how these topics affect commercial buildings. This article presents an overview of the effects U.S. model building and energy codes—along with industry standards—have on low-slope roofs (assembled with insulation above the roof deck) and exterior masonry walls."

Preliminary Energy Savings Announced for ASHRAE/IES 2016 Energy Standard [90.1]

Engineered Systems, Feb. 2017.
http://www.esmagazine.com/articles/98173

"More than 30% energy savings can be achieved using the 2016 version of Standard 90.1, according ASHRAE. The savings was found during a recent analysis conducted by Pacific Northwest National Laboratories (PNNL) in support of the U.S. Department of Energy (DOE) Building Energy Codes Program."

Refrigerants in Transition: Impacts on HVAC-System Design

HPAC Engineering, Dec. 2016, by Ryan Geister.

"With the world’s attention increasingly focused on climate change, organizations are more attuned to carbon-footprint implications during the building-design process and the impacts buildings have on the environment. HVAC-system efficiency plays a crucial role in a building’s environmental impact. While it is important to choose equipment that delivers high-efficiency performance, it is even more critical to consider a building’s entire HVAC system during design."

The IoT Opens New Opportunities for Energy Efficient Buildings

Energy Manager Today, Jan. 10, 2017, by Carl Weinschenk.

"The great potential for the Internet of Things (IoT) to improve energy efficiency in buildings was illustrated during the past week by an introduction and an investment. The problem addressed by the introduction is that the IoT is being deployed before interoperability and other standards and protocols are fully developed and in place. This means that the system – which even under the best of conditions will be monstrously complex and sophisticated – could devolve into islands of disconnected functionality. In such a future, the IoT would be of limited use – and may even be an overall detriment."

Smart Grid Standard Adopted by International Organization for Standardization

ASHRAE, Dec. 14, 2016, by Jodi Scott.
https://www.ashrae.org/news/2016/smart-grid-standard-adopted-by-international-organization-for-standardization

"A smart grid standard published earlier this year by ASHRAE and the National Electrical Manufacturers Association (NEMA) has been approved as an International Organization for Standardization (ISO) standard. ANSI/ASHRAE/NEMA Standard 201-2016, Facility Smart Grid Information Model (FSGIM), provides a common basis for electrical energy consumers to describe, manage and communicate about electrical energy consumptions and forecasts."

Calculating Economics of HVAC Systems

Consulting-Specifying Engineer, Dec. 2016.
http://www.csemag.com/single-article/calculating-economics-of-hvac-systems/3d4582c584ab8a0192fda3f906d67a07.html

"Codes and standards, equipment efficiencies, energy modeling, commissioning, energy-conservation incentive programs, and lifecycle cost analysis all play into determining the economics of HVAC systems. Included are key aspects a mechanical engineer may need to consider when specifying HVAC systems into new or existing buildings, with a focus on the economic analysis provided to the client."

DOE Completes New [Rotary] Air Compressor Standards

Appliance Standards Awareness Project, Dec. 5, 2016, by Chris Granda.
http://www.appliance-standards.org/blog/doe-completes-new-air-compressor-standards

"Today the U.S. Department of Energy (DOE) released new energy efficiency standards for rotary air compressors. These large air compressors power a range of commercial and industrial equipment such as manufacturing robots, pneumatic tools, and paint sprayers and use about 6 percent of all motor-driven electricity consumption in the industrial sector."

DOE Completes New Consensus-Based [Residential] Air Conditioner Standards

Appliance Standards Awareness Project, Dec. 5, 2016, by Andrew deLaski.
http://www.appliance-standards.org/blog/doe-completes-new-consensus-based-air-conditioner-standards?utm_source=Central+AC+final+rule

"The U.S. Department of Energy (DOE) published new minimum energy efficiency standards for residential central air conditioners and heat pumps today.  The new standards, which are based on a negotiated agreement, will reduce air conditioner and heat pump energy use by about 7%, translating into hundreds of dollars in electricity bill savings for consumers over the life of their equipment."

IECC Building Code Update: Three Issues to Watch

Code Watcher, Oct. 31, 2016, by Mike Collignon.
