During the Paris climate conference in December 2015, 195 different countries recognized the dangers of climate change. One of the key points on which the participants of this conference agreed on was that cities should built resilience against the effects of climate change. The changing climate has amongst others major consequences for water systems. In a country such as the Netherlands – which is extremely vulnerable to the consequences of flooding – water should be treated and used differently according to J.M. de Vries, former Secretary of State for Transport, Public Works and Water Management, in order to keep the Netherlands safe and livable. The climate will change considerably in the coming decades. Cities and their buildings will be affected. My graduation focuses on how water can be treated differently within the built environment related to climate change resilience. As project location, I have chosen 'Het Marineterrein' in Amsterdam. This area belongs to the Royal Navy until 2018. In this year, the Navy will leave and the area will be open for redevelopment from then on. My research on how water and its natural cycles can be integrated into a hotel building leads to a design of a bio hotel for 'Het Marineterrein', in Amsterdam. Within the hotel building and its surroundings water is purified, recycled and harvested. The hotel is an inspirational place for hotel guests, visitors and locals, where people can learn about water treatment related to climate change and where they can share their ideas and thoughts about the subject.
