To sustainably transform a National Monument that lies within a public and flexible city park that will also produce energy? How is that possible?

1. Return the monumental iron support structures and the uninsulated roof with its light sections of single glass panes to its original state. The result does not meet the building regulations.

2. Make use of the lack of insulation: retrieve the heat or cold from the indoor air with “inverted” radiators under the roof and store the energy in the underground water (WKO).

3. Make use of the lack of fire resistant materials: use the tram depot as a roofed outdoor area (RWA-installation) as a greenhouse, for temporary markets, fashion shows and parties.

More glass in the roof means more energy output. A full glass roof with the energy prices of 2012 will annually yield € 150,000.-. The installation and restoration will be recovered in about 10 years. The tram depot as an ecological power station is unique for Amsterdam (the largest public greenhouse) and the Netherlands (the largest ecological power station in the world)
