Fire Dampers 101 – Types, Testing, and Ratings

Fire dampers play a very important role in protecting buildings and saving lives in the event of a fire. Building codes require fire dampers to maintain the fire-resistance ratings of walls, partitions, and floors when penetrated by air ducts and transfer openings. (Figure 1) Upon detection of eleva

Does Your HVLS Fan Perform As Advertised?

High volume, low speed (HVLS) fans are large diameter ceiling fans that have gained significant popularity in the HVAC industry over the last several years. Like your ceiling fan at home, HVLS fans are a great way to circulate air and make the places that we live and work more comfortable. But, unli

Understanding LODs and its Use in Building Information Modeling

Building information modeling (BIM) in its most simplistic form is all about data; specifically, the data contained in individual BIM elements. These elements – e.g., walls, windows, doors, fixtures, etc. – are the building blocks of any building information model, and can each contain information t

How to Adjust Air Performance in the Field without Sheave Changes or VFDs on Adjustable Blade Fans

Air performance adjustments in the field are sometimes necessary for a variety of reasons. For example, the system’s design looks perfect on paper, but the realities of installation can require airflow changes. Other factors include unaccounted or overestimated pressures, or building renovations. It
