In times of rapidly rising energy costs and growing environmental awareness, we are increasingly focusing on the energy efficiency of buildings. One of the less obvious, yet significant sources of heat loss is… doors. Especially those that are heavily used – entrances, interiors, or industrial doors – can generate significant energy losses. Can door automation prevent this? Let’s find out.

  1. Where do doors lose the most heat?

Doors that are frequently opened and closed lose heat primarily through:

Warm air escaping in winter
Hot air inflowing in summer (stressing the air conditioning)
Creating drafts and destabilizing indoor conditions

The problem is exacerbated in high-traffic areas: office buildings, shops, hospitals, hotels, and warehouses.

2. Example: Entrance doors in an office building

Imagine an entrance door that opens 300 times a day, each opening lasting about 10 seconds. That’s a total of 50 minutes a day when the door is physically open, and the building is exposed to heat loss.

In practice, this means:

Annual energy losses: 500–700 kWh per door
At current thermal energy prices, this translates to PLN 300–500 in losses per year – and that’s just from a single point.

3. What does door automation change?

Using automatic sliding or swinging doors controlled by sensors brings specific benefits:

Minimized opening time – doors open only for the duration of passage
Elimination of accidental door closures
Full control of opening time (e.g., variable night/day settings)
Reduction in heat loss by up to 60–80%

4. When does automation really pay off?

Door automation makes the most economic and functional sense in the following cases:

Office buildings and corporate headquarters
Shops, shopping malls, and service outlets
Hospitals, clinics, laboratories
Hotels and guesthouses
Warehouses and manufacturing plants
Schools, universities, and government offices

Although doors are not typically associated with significant energy losses, their impact on a building’s thermal balance can be significant. Over the course of a year, they can generate real financial losses and reduce user comfort.

Door automation is a solution that:

Increases energy efficiency
Reduces heating and cooling bills
Improves comfort and safety
Can pay for itself in just a few years

In the face of rising utility costs and energy requirements, it’s worth considering automation not as an expense, but as a well-thought-out investment in the future of your building.
