A Dutch first: LEED Platinum sustainability certificate for TransPort office building

Today it was officially announced that the main office of transavia.com and Martinair has been awarded a LEED Platinum certificate. This is the first time that this internationally renowned sustainability certification has ever been awarded to a Dutch building. Deerns was responsable for all building systems.

LEED Platinum

LEED (Leadership in Energy and Environmental Design) is the international sustainability certification system that evaluates buildings on the basis of five environmental themes:

  • sustainable location,
  • efficient water use,
  • energy and climate,
  • materials and base materials,
  • and the quality of the indoor environment.

TransPort achieved the highest possible rating: “Platinum.”

Around the world, there is a strong effort to create sustainable real estate. At present, 6,326 projects worldwide are LEED certified, of which 371 have Platinum status (reference date: December 2010). Of these 371 Platinum buildings, seven can be found in Europe, three of which (with the inclusion of TransPort) are newly built office projects. The other office buildings with Platinum status can be found in Germany and Finland.

TransPort: a source of energy

As a building, TransPort both literally and figuratively provides energy to its environment. It inspires people, makes them happy, and promotes productivity. It is a smart building that came out of an inspired collaboration between the client, Schiphol Real Estate, the users, and all the construction partners involved. Several measures contributed to the success of the building: 

  • The design makes clever use of the sun and daylight, which benefits the indoor climate and saves energy. On TransPort’s southern side, slats prevent the sun from heating up the complex, leading to a substantial reduction in the building’s cooling requirement. In contrast, the northern façade is extremely transparent to allow for as much natural lighting as possible, which improves the quality of the work environment.

  • The building is heated and cooled by means of a geothermal heat pump. In addition, the roof is fitted with an exceptionally large number of solar cells with a surface area of nearly 900 m².

  • Digital technology ensures that the building’s in-house sustainable generation of energy is continuously transparent for its users. The integrated set of sustainability measures enables the building to perform 45% better than the energy performance standard adhered to in the Netherlands.

  • In selecting the materials, the goal was to use as many recycled raw materials as possible and to make sure that base materials and products were obtained and manufactured regionally (in Europe). The contractor succeeded in sourcing in such a way that ultimately nearly 40% of the building materials consist of recycled base materials and that over 60% of the building materials have been obtained and produced within a radius of 800 km of the construction site. Moreover, nearly all the wood in and around the building comes from sustainably managed forests (FSC certificate).

  • Various facilities for saving water ensure that the consumption of drinking water has been reduced by over 60%. In addition to the carefully selected plantings for the green roof, which can do without irrigation in the summer, the completed building is water-efficient due to the implementation of a rainwater system. This can be used to flush the toilets in combination with water-efficient showers and faucets. The urinals are even water-free.
