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.

 


Frequently Overlooked Requirements of 90.1-2013

ASHRAE Journal, Jan. 2016, by Daniel H. Nall.

"ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, has evolved rapidly over the years. As it has evolved, the requirements have changed, and some of these requirements have been overlooked by the engineering community. Some of these requirements are mandatory, meaning they must be incorporated on all projects for which they are applicable, and others are prescriptive."


Applying Demand-Controlled Ventilation

ASHRAE Journal, Jan. 2016, by Xingbin Lin and Josephine Lau.

"Demand-control ventilation (DCV) provides "automatic reduction of OA intake below design rates when the actual occupancy of spaces served by the system is less than design occupancy."1 CO2 sensing can be used to estimate the strength of occupant-related contaminant sources.2 This type of control approach is called CO2-based DCV. With a single-zone system, the breathing zone CO2 concentration can be used to directly control the outdoor air (OA) damper."

Zero Net Energy Buildings and the Grid

New Buildings Institute, Feb. 22, 2016, by Alexi Miller.

"As zero net energy (ZNE) and other low-energy buildings become increasingly common, we have to think about how different ZNE strategies can interact with their local electricity grids. The electricity grid was built as a one-way street, with energy flowing from the power plant to the consumer. Widely distributed renewable energy systems and other cutting-edge building technologies will change that equation."

How Healthcare FMs Achieve Energy Efficiency

"First of a 3-part article on how healthcare leaders [facility managers] are rethinking traditional practices to cut energy use."

Health, Wellbeing and Productivity in Retail: The Impact of Green Buildings on People and Profit

World Green Building Council, Feb. 2016.

"The report’s main finding is that retailers can improve the shopping experience for their customers and potentially increase their profits by providing greener, healthier stores."

Rooftop Solar Photovoltaic Technical Potential in the United States: A Detailed Assessment

National Renewable Energy Laboratory, Jan. 2016.
http://www.nrel.gov/docs/fy16osti/65298.pdf

"This report quantifies the technical potential of photovoltaic (PV) systems deployed on rooftops in the continental United States, estimating how much energy could be generated by installing PV on all suitable roof area. The results do not exclude systems based on their economic performance, and thus they provide an upper bound on potential deployment rather than a prediction of actual deployment."

Water Heaters: As Sexy as a Tesla?

Rocky Mountain Institute (RMI) Outlet, Feb. 24, 2016, by Margaret McCall.

"Of all the new tech emerging on the energy landscape, water heaters seem an unlikely contender. Alongside battery players like Tesla, with its Model X and Powerwall water heaters look like even more of a stretch. However, the growing industry consensus is that grid-interactive water heaters have serious potential. They just might be the unexpected battery in your basement."

Optimizing Airflows In Foodservice Facilities, Part 2 - Optimizing Exhaust Air

Engineered Systems, Jan. 2016, by Doug Horton.

"Many methods await when it comes to reducing exhaust rates. Fortunately, engineers can avail themselves of multiple tactics, from the hood specification to proper commissioning and air balance."

A Tale Of Three Boiler Plants

Engineered Systems, Jan. 2016, by Daniel McJacobson.
http://www.esmagazine.com/articles/97513-a-tale-of-three-boiler-plants

"School, warehouse, office building … the boiler stories they tell put the focus back on specific circumstances and smart pre-design study to ensure their systems (and budgets) enjoy the best of times for as long as possible. There is a widely held belief that high efficiency is always best. However, this is not necessarily the case."

Key Improvement Made in Solar Cell Voltage Technology

Washington State University News, Feb. 29, 2016, by Tina Hilding.
https://news.wsu.edu/2016/02/29/146010/#more-146010

"Researchers improved the maximum voltage available from a cadmium telluride (CdTe) solar cell, overcoming a practical limit that has been pursued for six decades and is key to improving efficiency. The work is published in the Feb. 29 issue of Nature Energy. The effort was led by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in collaboration with Washington State University and the University of Tennessee."
