Destratification Fan Savings Calculator
Facility energy costs can significantly reduce profit margins. HVLS (High-Volume, Low-Speed) fans help reduce these costs by improving productivity, minimizing HVAC strain, and reducing reliance on air conditioning systems. HVLS fans save both energy and money over time, translating into real financial gains. These energy cost reductions translate into real financial gains.
LED Lighting Supply’s ceiling fan cost savings tool helps contractors and facility managers accurately estimate fan energy consumption and potential cost savings from installing commercial and industrial ceiling fans.
Whether you operate a warehouse or manage a commercial facility, HVLS fans are a valuable investment as they improve comfort while increasing your bottom line. These types of fans help conserve energy year-round, making them an effective solution for all seasons. Our tool estimates the energy savings you can achieve by using destratification fans to improve destratification and thermal comfort throughout your building.

How to Use LED Lighting Supply's Free Destratification HVLS Fan Savings Calculator
Determine the number of commercial or industrial fans, fan size (diameter and number of fan blades), and the quoted price for installing fans across the entire space. A Product Specialist at LED Lighting Supply can design a fan layout plan ahead of purchase to recommend the proper fixture quantity, size, and investment price. Our Product Experts design custom layouts to ensure the requirements of the space are met. Fan specifications can be found on the fan’s label or user manual.
How to Determine Number of Fans:
Use our Ceiling Fan Count Calculator or speak to one of our Product Experts to determine the optimal ceiling fan count for your space.
How to Determine Fan Size:
LED Lighting Supply’s commercial and HVLS fans range from 8 to 24 feet in diameter.
How to Determine The Total Cost of Your Ceiling Fan Investment:
Add the price of each fan together and subtract any rebates or tax exemptions. If you received a custom solution from one of our Product Experts, they will break this down for you during your initial consultation.
Determine your building's average outdoor temperature, temperature at the ceiling, and temperature set point in Fahrenheit (°F). The default values are typical estimates for the United States.
How to Determine Average Outdoor Temperature in Heating Season (°F):
Varying weather conditions affect energy usage in facilities. To define your average outdoor temperature in the heating season, use a credible climate report to estimate the average daily temperature in a specific location. This report uses data from 14,000 weather stations across the United States and Canada. (Default: 28 °F)
How to Determine Average Temperature at Ceiling Deck (°F):
Warmer air naturally rises with the tendency of cooler air sinking. This, paired with material and environmental factors, causes the thermal performance at ceiling levels to vary. A reliable approximation of the average temperature at the ceiling deck is approximately 1°F per foot of ceiling height above floor temperature. (Default: 88 °F)
How to Determine Heating Season Indoor Set Point (°F):
Heating season indoor set point is defined as the average temperature that a building's thermostat is set to maintain while occupied. What is indoor set point? The set point typically varies from the actual room temperature. OSHA recommends a uniform temperature range of 68-76 degrees (F) for an ideal comfort zone. (Default: 59 °F)
Determine the distance between the heat source and the ceiling, the distance between the heat source and the floor, and the area of the facility in feet and square feet. The default values are typical estimates for a warehouse.
How to Determine the Distance Between the Heat Source and the Ceiling (ft):
To determine the distance between the HVAC system and the ceiling, measure the distance vertically starting at the top of the heat source to the surface of the ceiling. The distance from the heat source to the ceiling will differ if the HVAC equipment is elevated. (Default: 10 ft)
How to Determine the Distance Between the Heat Source and the Floor (ft):
To determine the distance between the HVAC system and the floor for raised or mounted systems, measure directly from the base of the heat source to the surface of the floor. For underfloor heating systems, refer to the installation manual for guidance. (Default: 25 ft)
How to Determine the Area of the Facility (ft2):
Measure the length of the facility and the width of the building. Multiply the length and width of the building's walls to determine the square footage of the facility. (Default: 20,000 ft2)
Determine the average number of heating season days, annual heating gas usage, and gas price. The default values are typical estimates.
How to Determine the Average Number of Heating Season Days:
Refer to the regional averages to determine the average number of heating season days. (Default: 220 days)
How to Determine the Annual Heating Gas Usage (Therms):
Refer to your facility's winter heating bills to determine the gas consumption for the total billing period. A therm is identified as a heat energy measurement, most commonly used to quantify natural gas consumption. A therm is equal to 100 cubic feet (cu ft). (Default: 20000 Therms)
Click the Therms button on the right of the projected area input box to toggle the measurement from therms or square thousand cubic feet (MCF).
Gas Price ($/Therm) Calculation:
To calculate your gas cost per therm, first define the volume of natural gas used in therms. Divide the volume (Therms) by 100 cubic feet. One therm is equal to 100 cubic feet (cu ft) of natural gas. Divide that value by the total gas cost. According to the U.S. Energy Information Administration, 0.75 Therms per Square Foot (SF) is a reasonable approximation in most commercial and industrial settings (2018). (Default: 0.5 $/Therm)
Click the $/Therms button on the right of the projected area input box to toggle the measurement from $/therm or $/square thousand cubic feet (MCF).
How to Determine Cost Per Therm Formula:
Use the formula below to calculate Cost Per Therm ($/therm)
- Cost Per Therm ($/therm) = Total Cost/(Volume of Gas in Therms/100)
Click Calculate to instantly generate your estimated gas, cost, and energy-saving benefits from installing commercial or industrial fans.
The Benefits of HVLS Fans
LED Lighting Supply’s HVLS fans are engineered to solve this issue by gently circulating large volumes of air at low speeds. This continuous movement causes warm air and cool air to mix from the floor to the ceiling. This process is referred to as destratification. The result is a maximized thermal satisfaction and an evenly distributed temperature. This uniform environment improves air quality for workers and operators while reducing energy consumption.
Convection, or the movement of heat through air within a space, is enhanced by HVLS fans in high-ceiling facilities. These fans create a forced convection cycle, circulating air from top to bottom ensures that when hot air rises, it’s quickly redistributed for uniform comfort. This process speeds up evaporation, reduces humidity, and contributes to better working conditions and overall employee comfort.
With proper destratification practices, businesses are less dependent on traditional heating and cooling systems. By circulating air throughout the entire space, our HVLS fans help facilities achieve energy savings of up to 15% by easing the burden on HVAC systems and enhancing overall energy efficiency. HVLS fans use power efficiently, which helps reduce operational costs, making them a cost-effective solution. In many cases, the energy savings achieved allow for a quick return on investment, with HVLS fan pay periods often being short due to the reduction in energy expenses.
