A new project will take advantage of the tower's vertical surface area by adding up to 2 MW of solar glass panels -- equivalent to a 10 acre solar field -- on the south side of the building's 56th floor.
This pilot project will use photovoltaic glass units developed by Pythagoras Solar. From Inhabitat:
The new windows, dubbed high power density photovoltaic glass units (PVGU), are a clever hybrid technology that lays typical monocrystalline silicon solar cell horizontally between two layers of glass to form an individual tile. An internal plastic reflective prism directs angled sunlight onto the solar cells but allows diffuse daylight and horizontal light through. Think of it as a louvered shade which allows for views but cuts out the harsh direct sun.
If the project is successful, it could lead the way to other similar projects in cities. It's a great way for cities to harvest energy without using up precious space in the city or limited rooftop space.
The product is also a potential breakthrough in energy efficiency in glass towers, where solar heat gain is the bane of energy-efficient design.
