Maintaining Temperature and Saving Energy with Air Barriers

Belfast International Airport Case Study

Belfast International airport is Northern Ireland's principal airport and the second largest gateway on the island of Ireland

Key objectives

Belfast International Airport asked us to help them find a solution to help maintain the temperature in the terminal building.

Their two main objectives were:

  • Maintain thermal comfort
  • Energy Efficiency

Challenge

Due to the high footfall and continuous use of their doors, it was very difficult to maintain a comfortable internal temperature. The temperature loss was affecting the overall thermal comfort,
thus creating associated problems with staff and passengers comfort and higher energy costs

Solution

We carried out a detailed site survey and proposed the best option was to install two Enershield Microshield MCS-48 units over each doorway. Designed and fitted with two auto-actuators meant that the units only came into operation when the doors were opened.

We recorded the temperature within a one metre range of the entrances and studied both doors; one with barrier turned off and the other on. This meant we could draw direct comparison in our results and show the effectiveness of the air barrier. When the unprotected door opened there was a sudden thermal exchange and the internal temperature fell to less than 10 degrees, in contrast on the protected doorway the set point temperature was maintained at over 16 degrees with the door open, proving that the air barrier is creating that highly effective seal across the doorway as promised. The air barriers are also preventing the ingress of smoke, odours and other airborne contaminants, therefore air quality and general cleanliness are additional benefits. Staff and passengers are finding the terminal more comfortable and as a result of the reduction in heat loss, reduced energy consumption has also been noticed.
