Facility energy costs reduce profits. HVLS fans save. LED Lighting Supply's destratification fan savings calculator helps contractors and facility managers accurately estimate the energy consumption and cost savings from installing industrial ceiling fans in your facility. This tool determines the estimated number of ceiling fans required to improve thermal satisfaction in your facility efficiently.

How to Use LED Lighting Supply's Free Destratification HVLS Fan Calculator:

Step 1: Enter Ceiling Fan Specifications

Fan specifications can be found on the label of the fan or fan's manual. A Product Specialist at LED Lighting Supply can engineer a fan plan ahead of purchase and recommend the proper fixture with accurate fixture counts. This will ensure your space requirements are met.

Step 2: Enter Temperature Measurements

The values entered for your space are typical values. All temperature measurements are calculated using a Fahrenheit (F) temperature scale.

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 heating season, use a 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.

How to Determine Average Temperature at Ceiling Deck (F):

Hot air rises with the tendency for cool air to sink. Paired with material and environmental factors this causes the thermal performance at ceiling levels to vary. A reliable approximation of the average temperature at the ceiling deck is for every 1F/foot of ceiling height above the temperature at floor level. The floor temp heat level will increase 1 degree F per foot. For example, if it is 65 degrees on the ground and the ceiling is 20 fee, the temperature would be 85F at the ceiling.

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 to balance worker comfort. 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.

Step 3: Enter Application Dimensions

How to determine the distance between the heat source and the ceiling:

To determine the distance between the HVAC system and ceiling, measure the distance vertically starting at the top of the heat source to the surface of the ceiling.

How to determine the distance between the heat source and the floor:

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 heating systems under the floor, determine the space by referencing the installation manual.

How to determine the area of the facility:

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.

Step 4. Determine Your Heating Usage Time (Seasonal Billing Details)

How to Determine Average Number of Heating Season Days:

Refer to the regional averages to determine the average number of heating season days.

How to Determine 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 utilized to quantify natural gas consumption and is equal to 1,000 cubic feet (cu ft).

How to Calculate Gas Price ($/Therms):

To calculate your gas cost per therm, first define the volume of natural gas used in therms. Divide the volume (Therms) by 1,000 cubic feet. One therm is equal to 100 cubic feet (cu ft) of natural gas. Divide that value by the total gas cost. 1 Therm per Square Foot (SF) is a reasonable approximation in most industrial settings.

How to Calculate Cost Per Therm:

Use the formula below to calculate Cost Per Therm ($/therm):

  • Cost Per Therm ($/therm) = TC/(V/1,000)

Step 5. Calculate

Click calculate to get your estimated gas, cost, and energy saving benefits by installing commercial or industrial fans.

How Do Led Lighting Supply's HVLS Fans Benefit Our Facility?

LED Lighting Supply's HVLS fans save by circulating airflow efficiently in large areas, regulating temperatures, and limiting HVAC system usage to improve energy efficiency by up to 15%. This results in peak performance, worker productivity, and maximum profitability. As employee comfort and well-being improves, facility costs decrease.

Convection is described as the movement of heat within a designated area. HVLS fans accelerate the movement of warmer air in high-ceiling facilities. This process is formed from a forced convection cycle that expedites evaporation, reduces humid working conditions, and prioritizes worker comfort.

HVLS fan destratification refers to the process of circulating rapid airflow, causing warm air and cooler air to mix from the floor to the ceiling. This creates a comfortable breeze zone, reducing the risk of potential heat stress to workers, improves air quality, and optimizes energy savings.

Our destratification fan savings calculator consists of five considerations: HVLS fan details, temperature, anticipated facility installation details, heat usage time, and energy costs.
