Natural Ventilation: Bringing Fresh Air Into Commercial Buildings

The Construction Specifier, June 2015, by Michael P. Toohey.
http://www.constructionspecifier.com/natural-ventilation-bringing-fresh-air-into-commercial-buildings/

"This article discusses the history of ventilation, describes its principles, and compares it with mechanical ventilation. The issues examined consider when specifying a separate window and actuator compared to an integrated natural ventilation system; it also addresses the options available for natural ventilation."

Deploy Grid Energy Storage Using Best Practices From Existing Installations

Solar Industry, June 2015, by Chris Thompson.
http://www.solarindustrymag.com/issues/SI1506/FEAT_03_Deploy-Grid-Energy-Storage-Using-Best-Practices-From-Existing-Installations.html

"...there are several commonalities between solar and grid-tied storage, and important lessons from the solar industry provide substantial guidance in energy storage application. Performance, pricing and packaging are the 'three Ps' of storage project deployment, derived from our direct experience in both solar and storage project deployment over the last few years."

Defining Indoor Air Quality: IAQ Means Different Things to Different People, Organizations

Air Conditioning, Heating, Refrigeration News, June 8, 2015, by Joanna R. Turpin.
http://www.achrnews.com/articles/129766-defining-indoor-air-quality

The Environmental Protection Agency (EPA), as well as "associations, such as ASHRAE, and individual states, including California and New Jersey, have put forward standards and regulations that address IAQ issues, but the definition of IAQ still remains somewhat nebulous. Perhaps that is because so many factors affect IAQ — everything from poor ventilation and high (or low) humidity to pesticides, mold, and radon. In addition, it can be a challenge to quantify proper IAQ, particularly when occupants in a space have varying tolerances to different contaminants and irritants."

Solar Canopies Turn Parking Lots Into Power Plants with Benefits

Solar Industry, June 2015, by Michael Puttre.
http://www.solarindustrymag.com/issues/SI1506/FEAT_01_Solar-Canopies-Turn-Parking-Lots-Into-Power-Plants-With-Benefits.html

"Solar developers say solar carports are emerging as one of the fastest-growing segments of the market -- particularly in places where getting into your car at the end of the day feels like laying tar in the hot sun."

LED Renovations and Retrofits: Evaluating Codes and Costs

Consulting-Specifying Engineer, May 2015, by Michael J. Mar and Robbie Chung.
http://www.csemag.com/single-article/led-renovations-and-retrofits-evaluating-codes-and-costs/bc0119cbc74ce2d8d32bf161ee087ff7.html

"Clients are asking lighting designers to help them save on energy costs, and replacing fluorescent, HID, or other lights with LEDs is in high demand. Here’s a look at the codes and guidelines that define LED use, including ASHRAE Standard 90.1, California Title 24, Dept. of Energy, and IECC."

Efficient Hot Water Systems

Consulting-Specifying Engineer, May 2015, by Cynthia Callaway.
http://www.csemag.com/single-article/efficient-hot-water-systems/61836908267937ed3fd5393eb7252fb1.html

"Engineers should work to design the most efficient water heating system or boiler possible. Understanding the codes/standards is paramount, followed by knowledge of the key equipment functions of boilers and similar systems."

How Energy Recovery Impacts IEQ

Buildings, May 2015, by Janelle Penny.
http://www.buildings.com/article-details/articleid/18838/title/how-energy-recovery-impacts-ieq.aspx?topic=410

"Energy recovery ventilators (ERVs) are a popular choice for fresh air ventilation, as they allow users to precondition the temperature and humidity of outdoor air using the waste energy from building exhaust. Not only does the fresh air and consistent temperature improve IEQ, the use of exhaust for conditioning reduces the mechanical heating and cooling load to save energy and money. Your occupants could likely benefit from a breath of fresh air – but is an ERV the way to accomplish that? Evaluate this technology for your facility below."
