Part One: Radiant Heating and Cooling Systems

ASHRAE Journal, Feb. 2015, by Kwang Woo Kim and Bjarne W. Olsen.
http://bookstore.ashrae.biz/journal/download.php?file=2015Feb_028-039_Olesen_pt-1.pdf

"This two-part article describes basic knowledge of radiant heating and cooling systems to give a principle understanding of the design and operation of this advantageous system including comfort, system load, heating/cooling capacity, installation and application of the system with examples."

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.

"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."

New National Furnace Standards Will Save Consumers Money, But Stronger Standards Could Save Even More

ACEEE Blog, Feb. 11, 2015, by Andrew deLaski.
http://aceee.org/blog/2015/02/new-national-furnace-standards-will-s

On Feb. 10, 2015, "the US Department of Energy (DOE) issued a proposed rule for furnaces that would provide significant savings for consumers on their home heating bills, and be among the biggest natural-gas saving standards ever completed by the agency. The new standards would reduce gas and propane furnace energy consumption by about 13% relative to basic furnaces sold today."

Gender and Thermal Comfort

Heating, Piping, Air Conditioning, Feb. 2015, by Lawrence Clark.
http://hpac.com/blog/gender-and-thermal-comfort

"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."

ASHRAE, IAQA Approve Consolidation

ASHRAE News, Feb. 5, 2015.
https://www.ashrae.org/news/2015/ashrae-iaqa-approve-consolidation

"A consolidation between ASHRAE and the Indoor Air Quality Association has been finalized by both organizations. The consolidation was approved by the Boards of Directors for ASHRAE and IAQA at ASHRAE’s recent 2015 Winter Conference in Chicago."
