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 I got started in the HVAC business half a century ago, I was very fortunate to work for a small firm where I learned a lot about design engineering from some really knowledgeable and practical HVAC engineers. The business we were in was designing HVAC for hospitals, colleges, universities, research facilities, and museums. All of these facilities required very sophisticated central air systems, heating systems, and chilled water systems.
What better time to talk about integrity than in a presidential election year. Certainly the perception of integrity within the building industry is much, much more low-key than the integrity of politicians, but it is the political environment that sets the bar for bad behavior.
This month’s B2B will focus on an existing datacom room located within a 200,000-sq-ft financial business office building. The existing datacom room is being expanded from 10,000 sq ft to 20,000 sq ft.
In last November’s Back2Basics, I created a test for the readers based on the idea that the patient room design was similar to a pharmaceutical cleanroom, with an air lock for people to enter and leave the room.
Unfortunately, the potential threats to building occupants are varied and increasing. To adapt properly, let’s look at the culture change needed in the design process. Commissioning, recommissioning, and preventive maintenance are further pieces of a strategy to assure ongoing safety.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop. Learn more about Grounded In Reality in the December issue. Other topics in the December issue include health care HVAC, Boilders, check out the Back2Basics, and more.
