Chilled-Water Piping Condensation Control for Energy Savings and Risk Avoidance

Insulation Outlook, Feb. 2015, by Richard Lubinski.
http://www.insulationoutlook.com/io/article.cfm?id=IO150203

"Proper mechanical insulation of chilled-water piping is critical. The life-cycle cost savings and risk avoidance made possible by insulating chilled-water piping is vital to the design of a high-functioning system. Chilled-water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping."

Case in Point: Symphony Hall Cooling Tower Hits the Right Notes

Engineered Systems, Mar. 2015.
http://www.esmagazine.com/articles/97021-symphony-hall-cooling-tower-hits-the-right-notes

"In an effort to eliminate disruptive airflow noises during performances, the Symphony Hall at The Woodruff Arts Center in Atlanta installed cooling towers designed with the benefit of quieter operation."

Energy Optimization In Existing Buildings

Engineered Systems, Mar. 2015, by Mohamed Abaza.

"The importance of focusing on energy optimization in existing buildings is crucial to reducing energy consumption and greenhouse gas emissions. In the U.S., existing buildings represent 85-90% of entire building stock (75+ billion sq ft). Buildings are responsible for an estimated 40% of U.S. primary energy use, 72% of electricity consumption, 39% of carbon emissions, and1 13.6% of potable water consumption."

Distribution and Substation Transformers: Design & Installation

Solar Pro, Mar./Apr. 2015, by Alexey Kondrashov and Tobin Booth.
http://solarprofessional.com/articles/design-installation/distribution-and-substation-transformers?v=disable_pagination

"In this article, we cover the fundamentals of transformer construction and operation. We discuss the general use of distribution and substation transformers in commercial and utility solar applications. We consider important transformer ratings and features. Finally, we summarize factory and field tests. If you do not take these considerations into account, the humble transformer can trip up your whole project. Our goal is to provide a definitive and practical guide that will help you select and specify pad-mounted distribution transformers for commercial and utility solar facilities."

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.
http://www.esmagazine.com/articles/96978-boiler-design-selection-what-engineers-should-keep-in-mind

"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.
http://www.esmagazine.com/articles/96977-humidification-options-for-commercial-buildings

"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."
