Great progress has been made in the renewal of the collective heat and cold storage system (C-ATES) on Evert van de Beekstraat in the Schiphol Business District.
The collective heat and cold storage system (C-ATES) now connects two prominent buildings in the Schiphol Business District: the Schiphol Headquarters and The Outlook. The Avioport building will follow later.
The Schiphol Headquarters was one of the first office buildings in the Netherlands to be connected to a collective WKO. The sources have now been replaced as they had reached the end of their technical lifespan. In the past period, four sources (2 cold and 2 warm) were drilled, each 180 meters deep, and a complex underground route was laid.
An important part of this project was making the building The Outlook gas-free. Here, among others, Microsoft, Cargill, Avolta, Spaces, and Customs are housed. Five heat pumps of 430 kW each (total 2,150 kW) now provide heating, supplemented by a booster heat pump for spaces that require higher temperatures. The gas boilers remain available only as a backup. The building is now fully electrically climatized.
The C-ATES system is invisible to the user but has a direct impact on sustainability performance. It saves approximately 625,000 m³ of natural gas (equivalent to the annual energy consumption of 415 households).
We are proud of the steps taken so far and look forward to further greening the office buildings.
