#Buildings producing their own energy prepared for tomorrow's cities An innovative façade, able to turn solar energy into heat for residentsuse,
and will prove its capabilities in real-life conditions The worldwide energy consumption of buildings is expected to grow by 45%from 2002 to 2025,
To reduce energy demand in old buildings across Europe, a consortium of researchers has designed an industrialised façade system for use in retrofitting works.
The system brings an imaginative technological solution that can be applied to different types of building
and façade orientations his system provides the tools for producing energy as well as insulating the building better:
The insulation technology is ready now for full-scale implementation in a real building in Merida, a city in the south of Spain.

#Expanding Smart Windows on a Global Level Raising $150 million USD in a recent late-stage series F investment,
electrochromic window company View has major plans for the future. Operating on small bouts of voltage that travel through a metal oxide coating within the dual pane windows,

The process is claimed to reduce energy bills by up to 20 percent a year by enabling buildings to regulate temperature within rather than resorting to air conditioning
and the subsequent costs associated with it. With only 100 installations to date (and preparations being made for 100 more View had been around for five years before installing its first window.

This new'thirsty'concrete absorbs 4, 000 litres of water in 60 seconds During the first few weeks of August 2007,

a new type of porous concrete that can absorb up to 4, 000 litres of water in the first 60 seconds,
all the water you can see pouring out in the video isn't being wasted-it's being fed straight back into the system for irrigation, drinking water, swimming pools,
While permeable concrete has been around for the past 50 years, it's mostly been used under pavements to help with drainage,
so the researchers at Tarmac figured out how to make a surface layer version of it that's capable of withstanding the weight of heavy traffic.

Fortunately, students in Switzerland have answered this very problem with the calevo an electric wheelchair that has the ability to ascend steps directly by lowering a tank-style tread that can roll the wheelchair up a flight of stairs.
