Ventilation and IAQ

RSS

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.

This month’s B2B will focus on a small city school system that chose to invest in an annual contract for a temporary air-cooled chiller for special events and an emergency crisis shelter center.

Evidence-based design (EBD), now a popular concept in health care facilities, is a very powerful tool.

Spring is finally springing, and just as blossoms start blooming, white papers and extra engineering content on our website will start … papering? 

The winter months are here! For those of us who live or work in in a cold climate, some form of heat is on, the windows are closed, and we may be sneezing and wheezing. 

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.

It’s not surprising that a brewery named for a river located in the untrammeled wilds of northern Maine would take its responsibilities to nature seriously. 

These sensitive applications call for looking at several established humidification techniques through a particular lens. The authors not only review the processes involved in various technologies but also some relevant secondary effects, such as a change (or no change) in the air temperature, that could be especially meaningful in a data center.

Generally, when we think about BAS, it is in the context of large commercial buildings, those well over 25,000 sq ft. According to the latest government data though (from the 2012 Commercial Building Energy Consumption Survey), 88% of all commercial buildings are 25,000 sq ft or less.

Keep your innovative drive running throughout the new year.
