NG Bailey turns up heating efficiency with solar cell glass and remote-controlled windows

The main entrance to the building, called Solais House, faces south and so gets a larger amount of sunlight than the other aspects of the office. The exterior wall of the foyer is almost completely photovoltaic glass, which generated 350kWh over the first six and a half weeks since the building came into operation. The glass costs £750 per square metre.

The glass is manufactured with integrated solar cells, with the cells acting as a shade for the sunniest side of the building. As one NG Bailey executive said: "We get a reduced cooling load size and some electricity for free."
