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.

 


9 Subtleties of Grid Storage Revealed

The Energy Collective, Oct. 28, 2016, by Xavier Moreau.

"Storing MWh of electricity in a battery at grid scale is not trivial because it requires a set of connected equipment and software that operate together: battery cells, power electronics, sensors, fire protection, telecommunication, relays, switchgears, controlling computer and software to name a few. Furthermore this system must be optimized along four dimensions: energy (quantity of electricity to be stored, i.e. MWh), power (flow of electricity, i.e. MW), chemistry (how electrons will actually be withheld, e.g. LiOn), and usage (charging/discharging cycles and ageing patterns over system life time)."

Advanced Heating Technologies for VRF

"Cold temperatures and disruptive precipitation create problems every year. When it comes to heating spaces, the challenge tends to be how to do 
it effectively and efficiently...Variable refrigerant flow (VRF) makes the most of the square footage and budget while offering energy-efficient and reliable technology providing superior occupant comfort. It achieves success by dividing a building’s interior into zones, each of which can be operated separately."

"Codes and standards require lighting engineers to include power allowances, daylighting controls, functional testing, and commissioning in lighting designs to verify lighting controls."

ASHRAE/IES Publish 2016 Energy Efficiency Standard [ASHRAE 90.1]

ASHRAE News, Oct. 26, 2016, by Jodi Scott.
https://www.ashrae.org/news/2016/ashrae-ies-publish-2016-energy-efficiency-standard

"Numerous energy savings measures resulting from industry input are contained in the newly published energy efficiency standard from ASHRAE and IES. ANSI/ASHRAE/IES Standard 90.1-2016, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings, contains 125 addenda published since the 2013 standard. This 2016 version is the 10th edition published since the original standard was first published in 1975 during the energy crisis of the United States."

"Don’t be deceived: They look like shipping containers. But the rows of massive metal boxes could contain the utility industry’s future. At least, that’s the hope of officials at the Snohomish County Public Utility District, which is installing a huge battery system near downtown Everett. The district’s goal for the $11.2 million project is to make energy storage cheaper and more flexible for utilities."

NEMA Publishes New White Paper on How to Reduce Energy Consumption in Commercial Buildings

"The National Electrical Manufacturers Association (NEMA) published a white paper that discusses new requirements that help reduce energy consumption in commercial buildings. NEMA WD ARCP 1-2016 Automatic Receptacle Control to Meet ASHRAE 90.1-2010 and California (CA) Title 24 explains the controlled receptacle requirement now appearing within non-residential energy codes, as well as a summary of typical application settings."

"As different as the energy industry is from the manufacturing and processing industries, there are increasing connection points between the two when it comes to Internet of Things technology deployments and the benefits that can be derived from them."

Weatherization Plus Health in Washington State: An Update

National Association for State Community Services, Oct. 26, 2016.
https://thestateofpoverty.org/2016/10/26/weatherization-plus-health-in-washington-state-an-update/

"In April, we described the launch of an exciting new weatherization venture in Washington State that combines the energy efficiency improvements of weatherization with a targeted approach to reduce and remove asthma triggers in low-income households. Six months later, the hard work of marrying weatherization to home health environment improvements is underway. The Washington State Low-Income Weatherization Assistance Program is learning a great deal about the challenges, and the promise, of energy savings and health impacts in low-income homes."

5 Unanswered Questions After Tesla's Big Solar Roof and Battery Announcement

".... Last Friday, CEO Elon Musk unveiled a slate of integrated solar roof and battery storage offerings that mimic the design of traditional roof shingles and eliminate the external mounted panel designDetails about the panel efficiency, battery life and overall cost were left out of Musk’s presentation, leaving a number of open questions about the sleek new Tesla offering and its potential impacts on the market."

Modeling Occupant Behavior

ASHRAE Journal, Oct. 2016, by Javad Khazaii.

"The current approach in building design focuses almost solely on increasing energy efficiency by improving system-oriented controls and behavior. However, occupant behavior also affects energy efficiency. To provide a more realistic modeling result, occupant behavior needs to be included in energy modeling."
