"The larger or more complex a cooling plant becomes, the more challenges to its efficiency it will face. When applied wisely, modern controls and equipment can rise to meet those challenges. Read up on active balancing, pump dynamic differential setpoint control, and more responsive tactics for when the worst thing you can do is just go with the flow."

"While CHP is good, CCHP can be even better for your facility and its locale. The author surveys the potential benefits, building code input, and electrical considerations. After a couple of case studies, she then reviews considerable engineering re-sources the DOE provides for those contemplating a forward-looking but proven design."

"By combining intermittent renewable energy sources through hybrid projects, developers are taking advantage of the strengths of each."

Smart Grid Standard Adopted by International Organization for Standardization

ASHRAE, Dec. 14, 2016, by Jodi Scott.
https://www.ashrae.org/news/2016/smart-grid-standard-adopted-by-international-organization-for-standardization

"A smart grid standard published earlier this year by ASHRAE and the National Electrical Manufacturers Association (NEMA) has been approved as an International Organization for Standardization (ISO) standard. ANSI/ASHRAE/NEMA Standard 201-2016, Facility Smart Grid Information Model (FSGIM), provides a common basis for electrical energy consumers to describe, manage and communicate about electrical energy consumptions and forecasts."

Floating PV: A Novel Approach To Solar

Solar Industry, Dec. 2016, by Bernard Prouvost.
http://issues.solarindustrymag.com/article/floating-pv-a-novel-approach-to-solar

"As solar power becomes increasingly affordable, accessible and prevalent around the world, new technologies and methods of installation are emerging. Specifically, floating solar PV is becoming a competitive and viable niche in the solar market that offers a water-based alternative to traditional PV installed on the ground, rooftops or carports."

Specifying HVAC Equipment in Critical Environments

The Construction Specifier, Dec. 2016, by Matt Strong.

"Cleanrooms present unique design challenges because they must meet specific requirements that go beyond what is encountered in a typical commercial space. When specifying HVAC equipment in a critical environment such as a cleanroom, engineers must consider the key issues of air filtration, humidity control, and pressurization. While a specifying engineer may have experience with these issues in the context of a traditional commercial application, the considerations are substantially different in a cleanroom."

Calculating Economics of HVAC Systems

Consulting-Specifying Engineer, Dec. 2016.
http://www.csemag.com/single-article/calculating-economics-of-hvac-systems/3d4582c584ab8a0192fda3f906d67a07.html

"Codes and standards, equipment efficiencies, energy modeling, commissioning, energy-conservation incentive programs, and lifecycle cost analysis all play into determining the economics of HVAC systems. Included are key aspects a mechanical engineer may need to consider when specifying HVAC systems into new or existing buildings, with a focus on the economic analysis provided to the client."
