During the construction of the original building in 1966, the concrete floor was of poor quality and it had to be blown up with dynamite in order to pour the new floor. In 1971 the tower was finished and 36 years later they decided to leave the building. After a period of vacancy the building will now house a nightclub, hotel, office space, parking and much more. The former structure is reused and the façade is redesigned in style of the Shell tower.
Today Amsterdam conducts the policy to build climate neutral. The ambition of Amsterdam is to build 40% climate neutral before 2015 and 100% climate neutral after 2015. Also for redesign the ambition of climate neutral design is being put into practice. (Noordwaarts 2012)
The selection of the architects Claus & Kaan for the new design was based on several criteria. Firstly the façade of the building needed to be thoroughly renovated in order to improve the insulating capacity, reduce the energy use and the application of sustainable materials suchs as FSC wood, and recycled materials. Secondly, peak interior temperatures need to be prevented by optimizing the use of heat and cold storage. Thirdly, the municipality proposes to incorporate the generation of sustainable energy in the renovation of the roof and façade. Finally, they aim to reduce the amount of traditional parking places and ask for a vision on electrical transportation applications.
These criteria are being monitored by the municipality before, during and after construction. Making sure the Toren Overhoeks will set an example for further sustainable development in renovation in the city of Amsterdam, where traditional rules and regulations often form great obstacles towards climate neutral redesign.
