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.

 


Integrated Design for Affordable, Factory Built Homes

ACEEE Summer Study on Energy Efficiency in Buildings, Aug. 2016, by Eric Ansanelli, Devanshi Dadia, Jordan Dentz, Zoe Kaufman, Emanuel Levy, Pournamasi Rath, and Greg Barker.

"In many respects that impact energy efficiency, manufactured housing is an anomaly in the shelter business. The industry builds to a national standard, most of the construction is done in a controlled manufacturing environment typically far removed from the building site, and portions of the home are completed by installers outside the control of the factory.... However, this is about to change as the industry energy standards, last updated in 1994, will be raised to levels roughly equivalent to IECC 2015, an unprecedented leap in efficiency regulation."

The Greatest Energy Story You Haven't Heard: How Investing in Energy Efficiency Changed the US Power Sector and Gave Us a Tool to Tackle Climate Change

ACEEE, Research Report U1604, August 19, 2016, by Maggie Molina, Patrick Kiker, and Seth Nowak.

"An invisible resource is working quietly behind the scenes to provide American families and businesses with the power necessary to live and work. This resource lowers harmful pollution, creates US jobs, reduces energy burdens for those most in need, and strengthens community resilience. It also improves the bottom line for business, returns at least double its investment, and saves American households, on average, $840 dollars a year. Energy efficiency has become the nation’s third-largest electricity resource. With increased support it could become the largest—and one of the world’s core strategies to tackle climate change."

Tackling Energy Codes with Energy Modeling: Preparing Design Professionals to Face Building Performance Demands

Building Codes Assistance Project for the Energy Foundation, Aug. 2016.
http://bcapcodes.org/wp-content/uploads/2016/08/Preparing-Design-Professionals-FINAL-08092016.pdf

"This paper intends to map the existing landscape of building energy codes and modeling software, highlighting current best practices and identifying steps for removing barriers. "

Our New Analysis Finds Energy Efficiency is the 3rd Largest Resource In the US Electric Power Sector

ACEEE Blog, Aug. 19, 2016, by Maggie Molina.

"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."

Chiller Plant Optimization Yields $386,000 Utility Rebate

Chiller & Cooling Best Practices, Aug. 2016, by Mike Flaherty.

"As a result of the project, this manufacturing site is saving approximately 4,450,000 kWh on 19,000,000 ton-hours of annual cooling production. This tremendous efficiency gain equates to $425,000 in energy annual savings and earned the site a $386,000 PECO utility rebate. The site’s chillers are now sequenced based on efficiency.  All pumps are variable speed and they are sequenced to meet the flow demand at the lowest total pumping energy. Consequently, the system pressure has been reduced from over 100 PSI to approximately 78 PSI."

Package Boilers Find New Friends

Plant Engineering, Jul/Aug 2016.
http://www.plantengineering.com/single-article/package-boilers-find-new-friends/6dff20bf020db5486b2b87a3b6963077.html

"For original equipment or replacements, package boilers offer efficiency, redundancy, flexibility: Advanced controls manage steam ramp-up and ramp-down for better combustion efficiency and heat transfer; improvements create efficiencies as high as 85%."

CHP a ‘Powerful Combination’ For Plants

Plant Engineering, Jul/Aug 2016, by Roy Palk.

"The pressure is on for industrial plants to become radically more energy efficient. The ongoing renaissance in combined heat and power (CHP), also known as cogeneration, is a major reason why."

Industrial Hydronic System Manual-Balancing Methods

Chiller & Cooling Best Practices, Aug. 2016, by Brandon Aitken.
http://www.coolingbestpractices.com/system-assessments/chillers/industrial-hydronic-system-manual-balancing-methods

"Hydronic balancing in industrial heating and cooling systems is an often overlooked final step in startup and commissioning of new and modified hydronic systems.  Insisting on a complete system balance upon startup of a new or modified system is an inexpensive insurance policy for any design engineer or installation contractor to protect their reputation against a system that is not performing to design conditions.  There are several methods of hydronic system balancing utilized in commercial and hospitality buildings, however, they are rarely found in the manufacturing and industrial environments."

Sparks Dynamics Optimizes NIST Compressed Air System

Compressed Air Best Practices, Aug. 2016, by Mac Mottley.

"Sparks Dynamics, a leading cloud based remote monitoring and data analytics technology company, entered into a Cooperative Research and Development Agreement (CRADA) with NIST researchers to develop industrial compressed air pattern analysis to enhance system efficiency and reliability."
