Berner International LLC Air Curtain Energy Savings Calculator (ESC) generates a payback period that is based on loads calculated from generalized customer input, TMY3 weather data, and ASHRAE calculations. Air curtain efficiency used to determine this payback period is based on generally accepted theory, laboratory and field tests. All results derived from ESC are for estimation only, actual payback period may vary. Berner International LLC is not responsible for variations in performance, input data, and payback, that may include and are not limited to site conditions, misapplication, energy costs, installation, etc.
Energy savings calculations include motor operating costs based on electrical utility rate.
The Berner Effectiveness Rating is a numerical scale representation assigned by Berner to its products to illustrate their effectiveness relative to each other.
Berner applies penalties to product performance based on mounting height, opening location and the products ability to resist wind.
The "generic air curtain" performance is based on the typical effectiveness of generally accepted performance achieved from a properly applied air curtain at conditions conducive to an air curtain solution.

Tips for Energy Efficiency
- Prioritize high-use openings. Doors that stay open longer or cycle frequently offer the greatest opportunity to reduce infiltration and energy loss.
- Match performance to the opening. Selecting the right air curtain for the size and type of opening is critical to achieving expected energy savings.
- Account for climate and building conditions. Temperature differences between indoors and outdoors directly impact energy loss, and potential savings.
- Use real operating data when possible. Accurate inputs (door usage, utility rates, hours of operation) lead to a more reliable air-curtain cost-savings analysis.
- Consider total facility impact. Evaluating multiple doors or openings can significantly increase overall savings and improve building-wide efficiency.
Savings FAQs
Energy savings vary based on door size, climate, and how often the door is used. In many commercial and warehouse environments, air curtains help reduce infiltration and energy loss by limiting the exchange of indoor and outdoor air, especially at frequently opened doors, resulting in measurable reductions in heating and cooling energy use.
Yes. By helping keep conditioned air inside, air curtains reduce the amount of outside air entering the building, which lowers the demand on heating and cooling systems. This can improve system efficiency and reduce overall energy consumption.
Air curtain ROI depends on factors like climate, energy costs, and door usage. Facilities with high-traffic openings or extended door-open times often see a faster payback period, as reducing HVAC energy loss can quickly translate into operational savings.
Yes. Warehouses and distribution centers are particularly susceptible to HVAC energy loss at open doors due to large openings and frequent use. Air curtains are an effective way to improve the energy efficiency of commercial buildings by reducing energy loss while maintaining access and workflow.
