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.

Commissioning Occupancy Sensors

Net Zero Buildings, Mar. 2017, by Barbara Horwitz-Bennett.
https://issuu.com/constructionbusinessmedia/docs/1703_nzb/26

"Lighting controls allow buildings to achieve significant savings in well-designed daylighted facilities. However, if these systems are not installed properly, notably occupancy sensors, a portion of these potential savings will be squandered. The solution: commission said sensors."

Optimized Energy Recovery

ASHRAE Journal, Jan. 2017, by Marvin Kirshenbaum.
http://ashraecok.org/images/downloads/Technical_Literature/journal_2017_01_optimized_energy_recovery.pdf

"This article addresses extending the application of waste heat recovery to both reheat and primary heating, allowing for a heat reclaim system no longer restricted to seasonal operation."

"A four-part article looking at how FMs can justify an LED upgrade."

Why Net Metering Matters For Commercial Solar, Too

Solar Industry, Jan. 2017, by Graham Smith.

"The C&I sector is often overlooked when it comes to the battle over NEM reform.... 2017 promises to hold many more discussions across the nation about NEM reform, from northwestern states like Utah, to the tip of the Northeast in New Hampshire and Maine. As policymakers and industry executives come together to decide on the future of solar, there must also be discussions about the effects of NEM reforms on C&I."

"Innovations aimed at enhancing energy efficiency, improving system performance, and prolonging equipment life."

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."

How To Calculate Life-Cycle Costs and Justify Energy Efficient HVAC Upgrades

Building Operating Management, Jan. 2017, by Conrad Kelso and Phil Lebrun.
http://www.facilitiesnet.com/hvac/article/How-To-Calculate-Life-Cycle-Costs-and-Justify-Energy-Efficient-HVAC-Upgrades--16971

"...a three-part article on how determining long-term costs can make energy efficiency more attractive to upper managers."

Why Would A Hospital Consider Absorption Chillers?

Engineered Systems, Nov. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/98005-why-would-a-hospital-consider-absorption-chillers

"While CHP is good, CCHP can be even better for your facility and its locale. The author surveys the potential benefits, building code input, and electrical considerations. After a couple of case studies, she then reviews considerable engineering re-sources the DOE provides for those contemplating a forward-looking but proven design."

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."
