A new book from ASHRAE and the Federation of European Heating, Ventilation and Air-Conditioning Associations (REHVA) provides guidance on designing chilled-beam systems.
The Active and Passive Beam Application Design Guide was produced through a collaboration of worldwide experts to give system designers a current, authoritative guide on successfully applying active and passive beam technology. Building on REHVA’s previously published Chilled Beam Application Guidebook, the new guide provides up-to-date tools and advice for designing, commissioning, and operating chilled-beam systems. It includes examples of active and passive beam calculations and selections.
Active and passive beam systems are energy-efficient solutions for spaces that require individual zone control and where internal moisture loads are moderate. “Active and passive beam systems provide good thermal comfort and energy and space saving advantages; and the operation of such systems is simple, with low maintenance requirements,” co-editor John Woollett said. “In a building where the goal is a low energy usage index, beams can be an excellent choice of indoor climate product.”
Although they are often referred to as “chilled” beams, in many cases active beams can be used for both heating and cooling. Active and passive beams are room air recirculation devices that transfer sensible heat to and from the space using water. In addition, conditioned primary air is ducted to active beams. Active and passive beams may be integrated with acoustic ceilings or independently mounted.

New ASHRAE standard may be too broad for the Canadian market
New Standard 189.1 from the American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE), which goes beyond energy efficiency to include provisions that affect construction, post-occupancy monitoring, and site control, may be too much for the Canadian market—at least for now.

Military tests show copper increases HVAC efficiency, reduces odors
Recent testing, which is being funded by the Department of Defense, is taking place in military barracks at Fort Jackson, South Carolina. Side-by-side comparisons demonstrate that air conditioning units made with copper suppress the growth of bacteria, mold, and mildew that cause odors and reduce system energy efficiency.

Cell and Genome Sciences Building, Farmington, Conn.
27th Annual Reconstruction Awards—Silver Award. Administrators at the University of Connecticut Health Center in Farmington didn’t think much of the 1970s building they planned to turn into the school’s Cell and Genome Sciences Building. It’s not that the former toxicology research facility was in such terrible shape, but the 117,800-sf structure had almost no windows and its interior was dark and chopped up.
