Spiderman sets his sights on world's tallest tower, a wind and solar powered roof in Perugia and a centre that converts sewage to heat opens in Canada.

DUBAI

Alain Robert, the French "spiderman" renowned for climbing the world’s most famous buildings with his bare hands only, has set his sites on the Burj Khalifa. Robert has previously climbed the Empire State Building, the Sears Tower and Taipei 101. He believes that the Middle Eastern heat could slow him down, but is still eager to give the world’s tallest tower a go.

ITALY

Coop Himmelblau has designed the Energy Roof in Perugia, powered by both wind and sun. It is self-sufficient and the west wing of the canopy is covered in transparent solar cells. The east wing captures the wind and generates energy through five wind turbines placed within the structure. The roof acts as a canopy over a gallery below and also connects a nearby metro station to the city centre.

CANADA

An energy centre in Vancouver that uses sewage to create heat and hot water was switched on late last week. The $30 million False Creek Energy Centre plans to create enough heat to warm the Olympic Village and thousands of new homes and businesses. The Centre will reduce greenhouse gas emissions in the neighbourhood by more than 50 per cent compared to the use of natural gas for heating.
