“Building on work that the firm began in the creation of an energy master plan for a development in Dubai, the Chicago Loop Energy Plan, currently in its initial stages, has involved an extensive survey of the dense building stock in the downtown area. AS+GG is now working on a preliminary plan to document and subsequently improve the energy performance of Chicago’s entire loop area.” AS+GG

“The team at Adrian Smith + Gordon Gill Architecture, known for net-zero and positive energy designs, lent its expertise to its hometown of Chicago in an effort to help the city meet its carbon reduction goals, which include 25 percent reduction in carbon emissions below 1990 levels by 2020 and 100 percent reduction in carbon emissions for new and renovated buildings by 2030, in accordance with the 2030 Challenge.

Because the typical Loop building is a tall tower with a relatively small footprint, there isnt enough room to install photovoltaics that could make a dent in energy usage. So reducing heat island effects to relieve the loads on air-conditioning systems is a more effective use of roof space.

The team created a 3D model of more than 550 downtown buildings, embedding information such as energy consumption, size, age, use, and estimated carbon footprint. This model helps determine which buildings need to be renovated to be brought up to standard, so that they can, potentially, gain new life as reprogrammed structures. Then the city can use the existing building stock rather than new construction to answer demand for more space. “I like the idea of operating on the scale of an entire city, and how you might be able to, in a piecemeal way, remedy” the carbon emissions problem, juror Frank Barkow said….”
