A simple solution for delta T trouble: Precision control valves help Atlanta buildings boost chilled-water system efficiency

When reflecting on factors that have the biggest impact on worker productivity, one might first think of flashy items such as computers, cell phones and the Internet. It might be surprising, then, to hear that creating uniform year-round comfort for building tenants can be just as important. While the heating, ventilation and air-conditioning system may not be the most notable feature of a productive office space, there is a strong correlation between office temperatures and worker productivity and performance. After a Cornell University study corroborated this point, news outlets devoted more attention to this association, noting that when temperatures drop or cannot be properly controlled, workers tend to make more mistakes. According to a FastCompany.com article on the Cornell research, "Want More Productive Workers? Adjust Your Thermostat" (Sept. 7, 2012), "When temperatures were low (68 degrees F, to be precise), employees committed 44 percent more errors and were less than half as productive as when temperatures were warm (a cozy 77 F). Cold employees weren't just uncomfortable, they were distracted. The drop in performance was costing employers 10 percent more per hour, per employee."
