The KLM Crown Lounge at Schiphol, opened in September 2008 is a good example of an energy-sparing building. It features a sun canopy and insulated glass with a high reflection factor. It uses modern, low-energy fluorescent lighting. And, sensors will reduce the lighting as external daylight increases. Heat recycling in the ventilation system will require less heating of the air. And the warm air removed from the space will be used to heat shower water.

The earth as thermos flask

Crown Lounge

Using our geothermal exchange system, we can store energy surpluses deep in the earth for the next season. The earth acts as a kind of thermos flask. The geothermal exchange system stores a surplus of cold in a watery layer in the earth and can be used in the summer for cooling. Conversely, we can store heat for heating in the winter. Pumps are used to drive the stored energy into the earth and back up again.



March 2010 saw the completion of TransPort, a sustainable building at Schiphol East that houses the head offices of KLM subsidiaries Transavia and Martinair. Around 1,100 m2 of solar panels supply 30% of the building’s electricity, a greywater system cuts water consumption by 40%, and the interior features a host of sustainable materials and bamboo fixtures.

The TransPort building meets guidelines laid down in the BREEAM-NL, a measuring instrument devised by the Dutch Green Building Council. Furthermore, TransPort is the first building in Europe that complies with criteria for Platinum LEED certification (Leadership in Energy and Environmental Design).
