Most hangars are made from metal, are several stories tall and are one big, wide-open space. A higher ceiling coupled with a large, open area usually leads to temperature inconsistencies throughout a building. HVLS fans are capable of covering a large area and those benefits are only more pronounced in taller buildings, as the air it pushes toward the ground only widens in a conical shape. The fact that metal conducts heat extremely well only adds to the need for the benefits that HVLS fans provide – primarily a light, cooling breeze. One not-so-obvious advantage of HVLS fans is that they deter birds from flying into and nesting in hangars, even when they are open to the outdoor elements. Controlling SSS and SBS HVLS fans can even aid in mitigating a health and safety issue – sweating slab syndrome (SSS) and sick building syndrome (SBS). SSS occurs when moisture intermittently develops on the surface of an interior concrete slab. These increases slipperiness of the concrete surface and poses a serious risk to people who walk on it. When warm, humid air enters the structure through open doorways, windows, and vents, it will condense on any surface that is at or below dew point temperature – often the floor surface. This often occurs in spring when cool evenings are followed by warm mornings. HVLS ceiling fans can help reduce or eliminate slab sweating by minimizing ceiling-to-floor temperature differentials and increasing the surface evaporation rate. SBS is used to describe what happens to building occupants who experience acute health issues. Most affected people have clinically identifiable symptoms (such as headache, dizziness, nausea) and typically feel better soon after leaving the building. Increasing ventilation rates and air distribution through means like HVLS fans often can be a cost-effective means of providing additional air flow, while also reducing indoor pollutant levels that can build up in ventilation systems. Getting the Right Spin Hangars are notoriously difficult structures to maintain temperature and comfort levels. However, the right type of HVLS fan can provide uniform air temperatures from ceiling to floor in an energy-efficient manner. Not to mention, improved air quality and a gentle breeze make the entire experience more enjoyable for anyone inside the structure. Andy Olson is the director of marketing for Rite-Hite Fans.
