If you’re the manager or owner of a warehouse, distribution center, fitness center — or any building that relies on an HVAC system — now is the time to consider installing HVLS commercial ceiling fans to help you lower heating and cooling costs.

As H.T. Lyons learned, HVLS ceiling fans take the load off the AC system by spreading larger volumes of cooler air more efficiently. (Download the case study to see how H.T. Lyons reduced AC tonnage 25% by adding HVLS fans to two HVAC warehouse systems.)

If you’re an engineer or architect and you want to spec HVLS fans into your building projects, we’ve updated our Engineering and Design Guide based on feedback from the field. The new 2011 E&D Guide features all new specification sheets, CAD drawings, and CSI spec sheets. Request your copy of the Guide by filling out our short form.

If you have questions about how HVLS commercial fans can help you or your customers lower energy costs and meet LEED and ENERGY STAR certifications, please call us. Our engineers and sales people are very happy to talk to you and help you choose the right size and number of fans for your building or project.

Inadequate ventilation / poor air quality – The activity that happens in a warehouse – from manufacturing production lines to forklifts spewing noxious fumes into the air to sheer people density – makes it imperative that warehouse owners and managers ensure fresh air is continuously circulated.

Although a building may have an air exhaust system, the opening and closing of dock doors creates short circuit scenarios. For example, the air pressure created in the suction of the exhaust circumvents the system intake devices. Even on a closed building system, the air drawn from the building and the air being replenished follow a path near the ceiling versus the the entire building’s air space. In other words, lots of stale air is left behind.

HVLS fans eliminate this problem as they continuously mix and churn all of the air inside a building.

Safety concerns – On high humidity days, water vapor is released into a building. Water vapor moves independently of air and always flows to the coldest point, such as concrete floors, which cool down at night. Once the concrete slab reaches dew point as temperatures increase, condensation is formed on the floor — posing real safety hazards to people and machinery (i.e. forklifts).

Because HVLS fans constantly mix air from roof to floor, a constant state of thermal equilibrium exists inside the building — and hence, condensation doesn’t form.

Skyrocketing energy costs – If a company uses air conditioning, it’s usually regulated to sections of the warehouse where products (i.e. pharmaceuticals) need to be kept at a constant temperature. And because AC is costly, companies hold the line on running it on a constant basis. Or, a company may be running dozens of high-speed 36″ fans, which are energy hogs.

In contrast, HVLS fans are incredibly energy efficient. One 24 foot HVLS fan can replace 25 36″ high velocity fans, can cover 10,000 square feet of space, and achieve efficiencies of 300+ CFM/Watt at full speed versus 18 – 20 CFM/Watt for 36″ high velocity fans.

HVLS fans also work very well in conjunction with air conditioning as they maintain constant humidity — allowing building managers to raise the AC set point by as much as 12 – 15 degrees. For each increase in degree, the energy savings is estimated at a 3 – 5% reduction in energy consumption.

And, if you’re designing a warehouse, including HVLS fans into your design enables you to lower the amount of AC tonnage needed – by 40%. (We have case studies coming – stay tuned!)

Personal comfort — When you’re hot, sticky and sweaty, you know even a little bit of air movement over your skin feels really good. This is because the air evaporates the sweat on your skin, which makes you feel cooler.

HVLS fans gently move a large column of air down and out, making everyone inside a building feel cool and comfortable.
