US-based Adrian Smith + Gordon Gill Architecture (AS+GG) has announced it is developing a planning strategy to reduce carbon emissions in densely populated cities.

AS+GG is developing the plan for the Chicago Loop area, which houses up to 550 buildings.

The firm has devised a survey to help develop a district-wide approach to sustainable retrofit and adaptive reuse. It also hopes this will help assess age, use, condition, and energy consumption of existing buildings in the district.

The firm’s Chicago Central Area Decarbonisation Plan aims to improve the performance of every building and to cut back on carbon emissions of 3.9 million metric tons to meet the challenges phased out until 2030.

The firm has surveyed 550 loop buildings and interviewed 24 of 83 building managers and is self sponsored with help from few local organisations.
