Chilled Water Thermal Energy Storage [TES] Hydraulics

ASHRAE Journal, Feb. 2015, by Kent W. Peterson.
http://bookstore.ashrae.biz/journal/download.php?file=2015Feb_040-043_EngNote_Peterson.pdf

"Chilled water thermal storage can provide many energy cost benefits when implemented in chilled water systems. Placing an atmospheric chilled water thermal energy storage tank in a chilled water system will have several engineering ramifications on the hydraulic performance of the system. Understanding these hydraulic implications and designing the optimum solutions for addressing these implications will improve both control and energy performance."


ASHRAE, REHVA Jointly Publish Guide to Chilled Beam Systems

Air Conditioning, Heating, Refrigeration News, Feb. 13, 2015.
http://www.achrnews.com/articles/128835-feb-13-2015-ashrae-rehva-jointly-publish-guide-to-chilled-beam-systems

"ASHRAE and the Federation of European Heating, Ventilation and Air-Conditioning Associations (REHVA) have published guidance on designing chilled beam systems. The Active and Passive Beam Application Design Guide is a collaboration to give system designers a current, authoritative guide on successfully applying active and passive beam technology."

Boiler Design & Selection: What Engineers Should Keep In Mind

Engineered Systems, Feb. 2015, by Mark Avron and Matthew Freeman.

"In the maze of specification choices, the customer's specific needs should still guide the design. Footprints and retrofits, associated pump/valve costs, and application type all point toward condensing or not, and high- or low-mass equipment. Find your way to long-term performance."

Humidification Options For Commercial Buildings

Engineered Systems, Feb. 2015, by Steven G. Liescheidt.

"Although industry debate about the research on acceptable humidity levels may continue, there is a growing realization that commercial buildings need some form of humidity control to provide optimum occupant comfort and productivity."

Variable Refrigerant Flow [VRF] Is Evolving

Engineered Systems, Feb. 2015, by Marcia Karr.
http://www.esmagazine.com/articles/96976-vrf-is-evolving

"While mechanical energy codes may lag relative to the efficiency targets of some other codes, the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehumidifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul."

FEMP Releases Top 20 List of Promising Technologies

FEMP Digest, U.S. Department of Energy, Feb. 9, 2015.
http://energy.gov/eere/femp/downloads/promising-technologies-list

"The Federal Energy Management Program’s [FEMP's] Promising Technologies List provides information about promising new and underutilized energy-saving technologies that are commercially available for deployment in the federal and commercial building sectors. The list includes twenty technologies with the largest potential for cost-effective energy savings if deployed throughout the federal sector, and previews a new FEMP database scheduled to go live in fall 2015."

Gender and Thermal Comfort

Heating, Piping, Air Conditioning, Feb. 2015, by Lawrence Clark.

"The lesson here is for designers to right-size HVAC systems. And because we cannot design different systems based on gender, maybe managers should be more sensitive to and flexible in personnel placement."

Adopting a Whole Building Systems Approach to Energy Efficiency

Business Energy, Dec. 2014, by Drake Erbe, Richard Lord, and Robert Wilkins.
http://www.businessenergy.net/DE/Articles/Adopting_a_Whole_Building_Systems_Approach_to_Ener_27631.aspx

"A new approach is needed to advance energy efficiency in buildings. A multitude of trends and innovations offer new opportunities for progress increasingly converging on the prospect of a new basic concept: whole building systems."

"A study prepared by Rocky Mountain Institute, Fisher Nickel, Inc. and New Buildings Institute examines the technical and financial feasibility of achieving new net zero energy restaurants in three cities: Chicago, Orlando and Washington, D.C."

Slash Plug Loads in 6 Steps

Buildings, Jan. 2015, by Janelle Penny.
http://www.buildings.com/article-details/articleid/18432/title/slash-plug-loads-in-6-steps.aspx

"Plug loads are becoming one of the fastest growing end uses of energy, the New Buildings Institute warns, and their drain on energy budgets is on the rise. [Plug load] includes any devices that plug into a building’s electrical system. In a typical office, the worst offenders are desktop equipment such as computers, monitors, and printers, notes Suzanne Foster Porter, director of research and technical services for ECOVA, an energy and sustainability management firm. Small offices also see a disproportionate amount of their plug load stemming from IT closets and computer rooms."
