Energy Efficient HVAC Systems for Airports

An airport has huge energy requirements and the costs are substantial. Understandably, airports are constantly looking for ways to reduce these costs. A recent study for the EU showed that in some airports the cost of running their HVAC systems accounts for nearly 50% of their overall energy costs. Fortunately, this is an area where significant savings can be made using the right equipment.

EU research found that, “the daily electricity and thermal energy used by a large airport compares to that of a city of 100,000 people.” For the two Italian airports they focused on, they suggested that re-setting heating controls and replacing faulty sensors could potentially save each airport 3,500 tonnes of CO2 and €70,000 a year.

How can you save energy with HVAC?

Outside Air

It sounds obvious but in cooler climates the outside temperature can be utilised in building cooling by simply increasing the flow of outside air.

Reusable Heat

Heat recovery units are another good way of saving energy, using the excess heat as thermal energy as opposed to being vented outside.

Variable Speed Fans

Being able to adjust the speed of fans in the system is important for energy saving as energy can be wasted if fans are operating at higher speeds than is necessary.


The EU study found that better monitoring would lead to more efficient running. Faults can be identified and put right earlier as well as the external conditions being monitored to ensure that HVAC systems are powering down when appropriate.

Replacement and Maintenance

It is not surprising that new and well maintained equipment runs much more efficiently than old and/or poorly maintained systems, but companies still attempt to save money by running old systems when it would, in fact, save them money to replace them.

The ideal situation, therefore, is for an airport to have a HVAC system which has been custom made to fit the requirements of the operation. Transcool Systems provide bespoke HVAC systems from first fix, to test and inspection.
