Pythagoras Solar, a provider of transparent, energy-efficient windows that generate solar power, today announced that it has been chosen by the Willis Tower, formerly the Sears Tower, in Chicago, Illinois to collaborate on a pilot project to help deliver on the building's renewable energy and energy efficiency improvement goals.
The pilot project, deployed in November 2010 on the south-facing windows of the Willis Tower's 56th floor, uses a building-integrated photovoltaic (BIPV) solution that has the potential to expand to a surface area allowing more than 2 megawatts (MW) of solar power generation. Willis Tower is exploring innovative solutions that directly reinvest in Chicago's new green economy. In addition, this project will illustrate one way to decrease the impact of the "built" environment on climate change.
Leveraging mass-scale solar power window installations has a direct impact on improving the energy efficiency and energy generation potential of a building's exterior envelope and windows. Pythagoras Solar offers a fully integrated photovoltaic glass unit (PVGU) that addresses the need for energy efficiency and high power density, while also offering architectural design benefits to increase real estate value and advance Net Zero Energy Buildings (NZB).
