"University ends 80-year dependence on coal."

Utilities and Customers are Embracing Community Solar -- Is Your Utility Next?

Northwest Public Power Association Bulletin, June 2015, by Joel Scruggs. [Scroll to page 26.]
http://www.nwppa.org/External/WCPages/WCWebContent/WebContentPage.aspx?ContentID=2352

"A quick survey of our utility members showed that while NWPPA utilities in every state they represent have customers and members with solar projects/net-metering projects on their own property, not many have community solar projects. However,  ...the word is out about them and many utilities are weighing the pros and cons of community solar — several members have even built one or are starting the process."

Maximizing Dust Collection System Efficiency

Compressed Air Best Practices, June 2015, by Hank van Ormer.

"A commonly overlooked area of inefficient compressed air use is dust collector pulse-jet cleaning — either bag (sock) type, or reverse flow filter type. Dust collector systems are vital to many plant operations, particularly with respect to meeting both indoor and outdoor air quality standards. They are also often used to collect income-producing product. At the heart of a pulse-jet type dust collector is the proper installation and availability of compressed air."

Determining the Economic Value of Compressed Air Measurement Systems

Compressed Air Best Practices, June 2015, by Tim Dugan.

"A common adage that has been quoted many times in this journal is: “If you don’t measure it, you can’t manage it.” This is partly true. It assumes that managers are willing and able to manage the costs and reliability of their compressed air system. Without data, however, they can’t do an effective job. But because managers are at times already overwhelmed with data, more data doesn’t automatically make them a better manager. A better way of saying it is: 'Appropriate measurement can make you a better manager.'"

Biomass District Energy Provides Economic, Environmental Benefits

Heating/Piping/Air Conditioning Engineering, June 2015.

"When John Cressy became facilities director for Sullivan County, N.H., six years ago, a study of the feasibility of utilizing biomass to reduce reliance on foreign fossil fuels and reduce carbon emissions was under way. The study did not meet the county’s expectations, and the entire project was shelved. Then, the Wood Education and Resource Center stepped in and offered to do a new feasibility study. 'The study blew our minds,' Cressy said. 'The numbers looked almost too good to be true.'"

Reusing Existing HVAC Systems and Components

ASHRAE Journal, June 2015, by Ramez Afify.

"During renovations, clients often ask if an existing oversized HVAC system or component can be reused. Budget constraints and timing are often cited.... This article reviews the impact of oversizing the most commonly used HVAC components. It also explores how new designs can be great designs if the engineered system has built-in flexibility, allowing a system to operate satisfactory under different loads and operating scenarios."

Residential Energy Efficiency Works. Don’t Make a Mountain Out of the E2e Molehill

American Council for an Energy-Efficient Economy (ACEEE), June 26, 2015, by Martin Kushler.
http://aceee.org/blog/2015/06/residential-energy-efficiency-works

"The Internet has been burning up these last two days with reactions to a new academic working paper (Do Energy Efficiency Investments Deliver? Evidence from the Weatherization Assistance Program) by researchers at the Energy Policy Institute at the University of Chicago (EPIC) and the University of California, Berkeley, associated with the E2e Project."

Duct Dynasty: Are Smart Vents Really That Smart?

Air Conditioning, Heating & Refrigeration News, May 25, 2015, by David Richardson.
http://www.achrnews.com/articles/129702-are-smart-vents-really-that-smart

"The concept behind the smart vent goes back to a myth that is decades old. The myth is that if you close the supply registers to rooms you don’t use, you’ll save energy by not heating or cooling those rooms. Sounds logical, right?  To understand some of the interactions these devices can cause with an HVAC system, you have to understand how dampering supply registers affects static pressure and system airflow. It’s also important to know how fans in HVAC equipment respond to these changes in static pressure."

Inverters: Efficient, Comfortable, Quiet: Ductless Technology Moves into Ducted ASHPs

Air Conditioning, Heating & Refrigeration News, May 25, 2015, by Joanna R. Turpin.
http://www.achrnews.com/articles/129701-inverters-efficient-comfortable-quiet

"Once the hallmark of high-efficiency ductless equipment, more manufacturers are incorporating inverter-driven compressors into their ducted air-source heat pump (ASHP) offerings. The reasons for this are simple: Inverter technology improves energy efficiency, provides better comfort, and offers quieter operation."

Barriers to Industrial Energy Efficiency: Report to Congress

U.S. Department of Energy, June 2015.
http://www.energy.gov/eere/amo/downloads/barriers-industrial-energy-efficiency-report-congress-june-2015

"This report examines barriers that impede the adoption of energy efficient technologies and practices in the industrial sector, and identifies successful examples and opportunities to overcome these barriers. Three groups of energy efficiency technologies and measures were examined: industrial end-use energy efficiency, industrial demand response, and industrial combined heat and power. This report also includes the estimated economic benefits from hypothetical Federal energy efficiency matching grants, as directed by the Act."
