Ultraviolet C (UV-C) technology has been used since the 1990s to eliminate microbial buildup on cooling coils, air filters, duct surfaces, and drain pans. But despite the technology’s history and track record, some facility engineers remain uncertain. On the other hand, some come around quickly.
Probably a year before 9/11, I was asked my thoughts along the lines of, “What else should we commission beyond the standard building systems?” My client was the project engineer at the Department of Defense in the Pentagon. I suggested “commission project record drawings.” I guess you could say I made up the task of commissioning record drawings, but I got my point across.
Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.
When it comes to writing an important research paper, it’s essential to include references. That’s exactly what Tom Mangogna had his district engineering staff do when it came time to research using Daikin for their school district.
Budgets, codes, and technologies are constantly shifting and evolving. These days, even the classrooms are often portable. Staying one step ahead will depend on your knowledge of current design options and how to integrate them into the space.
What is the difference between a typical BAS scenario and one that involves building analytics? And why did one library start to see its utility costs and trouble calls start to spiral upward? As you might imagine, the answers to these questions are related …
Since the early ’80s, building automation technology (BAS) have played an integral role in engineers’ ability to aid facility owners and operators in achieving operational efficiency, dependable comfort, and lower energy costs. However, despite significant capital investments, often times the full potential of these systems is not realized, resulting in less than optimal building performance.
Whether kids like school or not, attendance is mandatory for many years. Academic performance during this time often influences eventual jobs, income, and life satisfaction. During the formative years, parents mandate adequate sleep and good eating habits to improve their children’s concentration.
