Energy Newsbriefs Blog

The WSU Energy Program Library prepares this current awareness blog with funding from the U.S. Department of Energy State Energy Program. These articles highlight energy-related news, articles, and reports about energy efficiency, energy conservation, and renewable sources of energy for energy professionals and interested members of the public.

Is An LED Right For Your Next Retrofit Project?

Consulting-Specifying Engineer, Aug. 2016, by Tom Divine.
http://www.csemag.com/single-article/is-an-led-right-for-your-next-retrofit-project/c0bac149cf0b264d0f0ac4fa9cf2a0bb.html

"As LED illumination technology improves in efficiency, reliability, and quality, building owners become interested in cost-effective ways to apply LED lighting in their facilities. In many cases, retrofitting existing fluorescent or incandescent luminaires will be an attractive alternative to wholesale fixture replacement. This article explores the effects of some of the applicable codes on LED retrofit projects."

Energy Trust Tops 10,000 Energy Efficient Homes

Portland Business Journal, Aug. 16, 2016, by Jon Bell.

"Just 300 homes built in Oregon in 2009 had an Energy Performance Score, the energy performance rating tool developed by the Energy Trust of Oregon. In 2015, that number soared to 2,500 homes.As of this month, all of those numbers have helped Energy Trust surpass the 10,000 mark when it comes to homes rated with an EPS. According to the nonprofit, more than a third of new homes built in Oregon these days have an EPS."

You Can’t Make Bricks Without Straw: Building a Residential Energy Code Support Program from a Utility Perspective

ACEEE Summer Study on Energy Efficiency in Buildings, Aug. 2016, by Donald C. Boza, Jr., Chad Miller, Joshua Rego, Cherish Smith, and Stu Slote.

"Improvements in building energy codes cannot be fully realized unless targeted stakeholder education, training and outreach is provided to support increased understanding of and compliance with the minimum requirements... This paper presents an approach developed to assess the energy savings and benefit-costs associated with implementing an energy code education, training and outreach program in Michigan."


Beyond Compliance: The DOE Residential Energy Code Field Study

ACEEE Summer Study on Energy Efficiency in Buildings, Aug. 2016, by David Cohan, Jeremy Williams, Rosemarie Bartlett, Mark Halverson, and Vrushali Mendon.
http://aceee.org/files/proceedings/2016/data/papers/5_18.pdf

"For each state, energy use intensities (EUI’s) were calculated for a home just meeting the state prescriptive code requirements and compared to an EUI representing the collected field data. Results suggest that, on average, energy codes deliver most or all expected energy savings for the code adopted in a given state, overall—the opposite of conventional wisdom. At the same time, many sampled homes failed to meet at least one key code requirement, and many of the non-key requirements were not met. Also, the adopted code varied by state so there is clearly more energy savings potential available from adopting new codes. This rich new data set will
drive important discussions on the value and role of energy codes

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."

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. "

Regulation of Commercial Fan Efficiency: An In-depth Exploration of the Department of Energy’s Fan and Blower Rule

Business Energy, Jul/Aug 2016, by Trinity Persful.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-efficiency/regulation-of-commercial-fan-efficiency/

"Fans consume 14% of the electricity purchased by industrial and commercial buildings. Yet, fan efficiency has escaped the attention of those who design efficiency into the air systems they specify. That is about to change. The US Department of Energy (DOE) will publish their proposed rule this year covering fans from 1 to 200 horsepower. This new regulation will determine compliance at the design point of the fan."

Update on U.S. Fan Energy-Efficiency Regulation

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

"Progress to date and future direction of efforts to reduce fan power consumption."

Mobile Homes Move Toward Efficiency

ACEEE Blog, Aug. 3, 2016, by Lowell Ungar.

"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”."

zEPI FAQ: Zero Energy Performance Index

New Buildings Institute, July 2016.
http://newbuildings.org/code_policy/zepi/

"The 2015 International Green Construction Code (IgCC) includes many progressive measures that will improve the energy performance of buildings. One important provision describes the Zero Energy Performance Index (zEPI), which provides a scale for measuring commercial building energy performance. zEPI represents a fundamental shift in measurement of building efficiency as it sets energy targets for actual energy consumption rather than using a predictive energy model of building energy performance to calculate a “percent better than code” metric. zEPI sets an energy use intensity (EUI) target for building type and is adjusted for climate. It is also the measure by which a building’s energy efficiency is calculated once operational and occupied based on measured energy use data."
