Missed Opportunities with Chillers

IceBank Tanks

By Paul Valenta, LEED AP

The HVAC system is rarely thoroughly studied or analyzed until there is a problem. In the daily activities of running a business or managing a building, HVAC is out of sight, out of mind until things get too hot or cold. Then, productivity drops and costs increase as chillers limp along with Band-Aid fixes that result in expensive after-hour service calls. Replacing the chiller with a newer version (i.e. the …

(That standard’s title notwithstanding, the test is performed on both load-bearing and non-load-bearing wall assemblies.) Its successful completion demonstrates the ability of an exterior wall mockup to contain vertical and horizontal flame spread …

R-values: Controversy and performance values

By Ken Wells

What exactly is R-value? This question is not asked often enough in today’s environmentally conscious design/construction industry. However, an even better question may be, whether R-value is still a valid unit of measurement for the performance of insulation products. (And, if not, why is it being used as the predominate gauge to compare them.) To answer these questions, this two-part series discusses how R-value came to be and how it is used.1

By Lynn Walters

Unwanted building envelope heat transfer can be a unique problem in commercial construction and retrofit. With the nationwide push for energy conservation and more efficient buildings, architects, engineers, and designers are being asked to come up with viable solutions. There is a large array of products to choose from that can solve many of these obstacles—one in particular is the interior radiation control coating (IRCC).

Florida gets top marks, but North Carolina and Louisiana have taken steps backward when it comes to building codes and the threat of hurricanes, according to an Insurance Institute for Business & Home Safety (IBHS) report.
