Energy efficient refurbishment: Ruins of a pre-war holiday building to become most energy efficient youth hostel

Prora was a 4.5 km long block building planned and erected between 1935 and 1939 on the island of Rügen in Germany. After the war the listed building was not in use and fell into decay. Now a 500 m long section of the building will be refurbished to...
The energy efficient retrofit concept is based on a reduction of the primary energy need to a third of the German requirements for new buildings and on the environmental friendly supply of the remaining need including the neutralisation of...
