Building entrances have a significant impact on the energy consumption of the facility. Automatic doors can save energy through greater control of air flow. The greater control you have over the flow of hot or cold air from the inside of the building to the outside, the more efficient your entrances are, and the greater your savings will be.
Non-automated doors need to be opened or closed by the user manually (unless the door has a spring closing mechanism). When the door is not closed by the user on entry or exit for any reason, it can cause a steady exchange of air between the inside and outside of the building, leading to loss of hot or cold air from within, which can affect user comfort and have a direct impact on the energy efficiency of your building.
Automated doors are designed to keep close control over air flow and energy loss in the building. All automated doors including sliding and swing doors as well as industrial doors such as overhead sectional doors and high-performance doors feature smart sensors that ensure they will only open when someone needs to pass through, closing quickly after them to minimise air flow. Revolving doors are, by design, energy efficient as they are ‘always closed’.
Automated doors can also be specified with additional insulation (via insulated panels or double glazing) and tight seals to reduce energy loss. Doors with fast opening and closing cycles reduce the amount of time that energy has to escape.
If it’s energy efficiency you’re seeking in your entrance solution, choose automated doors. Where available, take a look at the door’s EPD (Environmental Product Declaration).
