This past August, I wrote in this column about the opportunity to invest in a niche business providing temporary HVAC design and construction administration.
Mold concerns became highlighted in the 1920s, when commercial and military needs for safe storage and transport of supplies focused attention on preventing biological deterioration of materials.
Clarify the difference between pressure dependent and pressure independent systems, and then make a deep dive into this TAB process. There’s a lot of science involved, but in the end, steering and tweaking the process may seem more like an art.
Hotels and other high-rise buildings can easily develop indoor humidity issues if they don’t deal properly with the outside air component of their ventilation design. Reclaiming waste heat in a way that suits the circumstances can be a pivotal step toward correcting or avoiding such problems. With a Chicago condo as one example, learn to work through assorted benefits and caveats to reach the right fix.
How often has an AHU or system been reused as part of a building renovation project and/or to expand the area served by the associated unit to provide additional air conditioning or heating?
In a sense, HVAC engineers are the physicians of the built environment because IAQ and water management determine the growth and transmission of microorganisms.
Not exactly business as usual: a retrofit of a retrofit involving custom air handling boxes and the limitations of a historical building. The project team assessed the possible routes and mapped a course guided by VRF capabilities and precision work onsite.
Historically used in smaller-load residential settings, electronically commutated mo-tor (ECM) technology is making the leap thanks to recent improvements and in-creased awareness among engineers. Start with the basics, proceed to advantages and caveats, and consider the ways ECM designs can streamline the economics of air movement.
According to the United States Department of Energy, motors in homes and commercial buildings consume more than one-third of all the electricity used in these buildings.
While travelling in Europe to the Indoor Air 2016 conference in Belgium, I had the opportunity to discuss a largely unspoken shift in the management of IAQ with a like-minded colleague, Dr. Walter Hugentobler from the University of Zurich, Switzerland.
