Energy-efficient solutions save the environment

Completed in 2009, the extension boasts numerous features that not only cut energy consumption, but also energy costs.
 
Aircraft stands are heating using district heating network return water, which has already released a majority of its thermal energy in heating the terminal buildings. The energy-efficient district heating solution offers reasonable savings compared to electric heating. "At current energy prices, this could mean as much as 50,000 euros a year," says Antti Savolainen, an electrical engineer with Finavia.
 
Energy-efficiency can also be found in the extension apron lighting systems, which can be adjusted according to need: when there are no active functions being carried out, the lighting output is reduced.
 
New environmentally-friendly technologies for the old terminal
 
Environmental perspectives have also been taken into consideration in Terminal 2 renovation work, which is currently underway. The lighting system for Terminal 2's public areas will be completely updated, thus reducing the current electrical power output by approximately 100 kW.
 
Indeed, a great deal of work has already been done in Terminal 2. The new check-in area has a utility automation system that regulates lighting, air conditioning and heating according to need. Optimising power output saves a huge amount of energy.
 
Co-ordinator of Finavia's energy and climate programme, Deputy Director Reijo Särkkä promises that more energy-saving solutions are in store.
 
"Next, we're going to examine free cooling, which makes use of cool outdoor air. Other areas needing improvement include the use of new, more energy-efficient lighting in the airport lighting systems as well as the installation of air and geothermal heat pumps in future renovation areas.
