"Even with today’s falling energy prices, facility managers are looking for ways to reduce the energy use of HVAC systems. New technologies and improvements in existing technologies are giving facility managers options. While advances can be seen in practically all HVAC systems, some of the most significant advances are coming in three particular areas: variable refrigerant flow systems, rooftop units, and geothermal systems."

Driving Data Center PUE, Efficiency

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Bill Kosik.

"For the last decade, power usage effectiveness (PUE) has been the primary metric in judging how efficiently energy is used in powering a data center. PUE is a simple energy-use ratio where the total energy of the data center facility is the numerator, and the energy use of the information technology (IT) systems is the denominator."

Evaluating UPS System Efficiency

"Many modern uninterruptible power supply (UPS) systems have an energy-saving operating mode. Data show that very few data centers put it to use because of the potential risks."

Understanding Cogeneration Systems

http://www.csemag.com/single-article/understanding-cogeneration-systems/ebec65943f512c49199b852db0b51104.html

"Cogeneration systems—also known as combined heat and power (CHP) systems—generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements." Describes three CHP system prime movers: back-pressure steam turbine, combustion turbine, and reciprocating engine.

Implementing Microgrids: Controlling Campus, Community Power Generation

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Paul Barter and Edward T. Borer.

"Microgrids are subsets of the regional electrical grid that have the ability to operate independent, or “island,” from the local utility. Microgrids normally operate in parallel with the utility, but they can operate in an isolated mode when utility service is interrupted or providing poor power quality. The design and operation of microgrids are optimized around the needs of the specific end users they serve."

Is VRF Right for Your Next Project?

"Variable refrigerant flow (VRF) systems can be specified into a variety of buildings, especially those that require flexibility. An overview of these systems and some best practices have been provided by Julianne Laue, PE, LLED AP BD+C, BEMP, senior energy engineer at the Center for Energy Performance, Mortenson, Minneapolis."

Case Study: Working Example: Zero Net Energy Center

High Performing Buildings, Summer 2015, by Michael Hummel and others.
http://www.hpbmagazine.org/attachments/article/12211/15Su-Zero-Net-Energy-Center-San-Leandro-CA.pdf

"To prepare electrical apprentices for working in the sustainable building industry in Northern California, the Zero Net Energy Center is a working example of an emerging phenomenon. The International Brotherhood of Electrical Workers Local Union 595 (IBEW) and the Northern California Chapter, National Electrical Contractors Association (NECA) created a world-class learning environment for apprentices to gain hands-on experience with cutting-edge technology and electrical systems. The ZNEC also addresses the need to repurpose the existing building stock in the U.S. by transforming a typical 1980s suburban office building into a modern net zero energy showcase. "
