The proposal envisions the building as a sustainable landmark for the city of Oslo with 90 percent of all the existing material to be recycled and used as new building materials. 80 percent of that will be used directly as part of the refurbished high-rise. Other sustainable systems deployed will include water reuse, heat and water recycling, solar chimneys, greenhouses, and “green lungs”-a habitat made of regional plants that regulate indoor climate.
The main access to the building is provided through an Urban Green Mall, which offers visitors locally produced food and a variety of cafes and restaurants.
Urban Mountain won the Nordic Built Challenge in Norway, which is a part of the Nordic Built Challenge Award. As national winners, Schmidt Hammer Lassen Architects has become one of the teams competing for the grand prize with other Nordic countries. The overall winner will be announced on 17 October, 2013.
