On Mount Ararat, Greenpeace volunteers are working feverishly to make Noah’s Ark to raise awareness about global warming. This is a neat and creative idea. The message about climate change is targeted at politicians.
Volunteers are racing to complete the wooden vessel under bright sunshine by end-May, to coincide with a summit of leading countries next month in Germany where climate change will be high on the agenda.
PGIGrup is about to make Europe’s largest solar roof. The building is going to be built in Madrid and generate 3 megawatts of electricity.
At over a kilometer in length, the rooftop will have an area of over 57,000 square meters, of which 21,000 will be occupied by solar panels. The power installed will be of approximately 3 MW peak, which will generate over 3.6 GWh per year.
It is predicted that this design will enable it to save 15% on climate conditioning in winter, and 34% in summer, as well as saving on lighting. The facade of the office blocks is a double skin, where the external glass is hung out from staggered glass fins.
