Anyone looking at Schiphol from a distance at night can see that it takes a lot of energy to keep a modern city like Schiphol running 24 hours a day.
We use more than 175 million kWh in electricity alone. That equals well over the amount used by 50,000 households! In an agreement with the government, Schiphol has committed to ensuring energy consumption over the 2005-2020 period grows by 2% less than what might be expected on the basis of passenger volumes and expansion of the real estate portfolio. This commitment applies to our own operations at the Schiphol location.
Measures for using energy more efficiently
Using energy as efficiently as possible is quite a challenge. Nevertheless, we implemented a wide range of measures to this end in 2015. As a result, we handled more aircraft, passengers and cargo using proportionately less energy.
We took the following measures:
- A large share of the public area and car park lighting was replaced with LED lighting.
- Large cooling units and air treatments units made way for heat and cold storage.
- Signs and systems are switched off more often where possible.
- We signed sustainable management and maintenance contracts with our main contractors. This creates a more comfortable environment for building users and reduces energy use.
- We have initiated the process to obtain BREEAM-NL in-use sustainability certification for our office portfolio.
- We are developing an energy-neutral mobile commercial multi-tenant building at Schiphol-East.
What are the results so far?
In 2015, the combined measures yielded energy savings of more than 60 TJ (terajoule), which is comparable to the energy consumption of around 730 households. We are pleased to have met our 4.1% reduction target. Our absolute energy consumption did increase by 40 TJ. This is attributable in part to the fact that the 2015 operating year, which ran from 1 November 2014 till 31 October 2015, was slightly colder than the 2014 operating year. Consumption was also higher because apron buses now require electric charging; however, this is offset by the fact that they are no longer producing diesel emissions. For 2016 we have set the same energy efficiency target of 4%.
Measures at Rotterdam The Hague Airport
In 2015 the terminal of Rotterdam The Hague Airport was connected to a collective heat and cold storage (HCS) system, which has dramatically lowered gas consumption. The full effect will be measured in 2016. In addition, solar panels have been installed on the roof of the terminal and on a new building. The new second arrivals hall slated for completion in April 2016 has been designed to minimise energy consumption, with solar panels on the roof, LED lighting and a HCS connection.
Sustainable energy through heat and cold storage
Heat and cold storage (HCS) is an important sustainable energy solution for Schiphol. The ground under Schiphol is ideally suited to HCS. Two new sources were activated in 2015: one to supply the new Hilton hotel and another for the new security filter to Piers G and H. The HCS supply for Pier F, which was taken out of operation during construction of the central security facilities, will also be reactivated.
