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.

 


Advancing Elevator Energy Efficiency

ACEEE, Jan. 2015, by Harvey Sachs, Harry Misuriello, and Sameer Kwatra.
http://www.aceee.org/sites/default/files/publications/researchreports/a1501.pdf

"This paper describes recent advances in energy-saving elevator technologies and recommends a path for accelerating the uptake of these new capabilities. New building codes are stimulating the adoption of modern systems that can save more than 40% of current annual energy use. ACEEE recommends actions by manufacturers, ASHRAE, public benefits programs (including utility incentives), voluntary labeling programs, and government to encourage further innovation. We recommend that industry adopt an efficiency rating system and an industry-owned premium product label."

Boiler Design & Selection: What Engineers Should Keep In Mind

Engineered Systems, Feb. 2015, by Mark Avron and Matthew Freeman.

"In the maze of specification choices, the customer's specific needs should still guide the design. Footprints and retrofits, associated pump/valve costs, and application type all point toward condensing or not, and high- or low-mass equipment. Find your way to long-term performance."

Humidification Options For Commercial Buildings

"A Portland start-up has tapped the city’s water pipes as a new source of renewable hydropower that doesn’t disrupt fish migration or stream flows."

Variable Refrigerant Flow [VRF] Is Evolving

Engineered Systems, Feb. 2015, by Marcia Karr.
http://www.esmagazine.com/articles/96976-vrf-is-evolving

"While mechanical energy codes may lag relative to the efficiency targets of some other codes, the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehumidifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul."

Energy Impacts of Laboratory Ventilation Methods

Heating/Piping/Air Conditioning Engineering, Feb. 2015, by Victoria Herman and others.
