How Green is your Apartment/Condo Building?

This map illustrates the global warming potential (GWP) per square foot of residential buildings in Chicago.

The GWP (kg C02e/SF) is calculated from the amount and type of energy each building used in 2018. GWP approximates the amount of greenhouse gas emitted to provide the building’s energy. For instance, a building with a GWP per square foot of 10 emitted the equivalent of 10 kg of Carbon Dioxide in 2018 for every square foot of floor area.

GWP is a useful comparison because different sources of energy produce different amounts of different types of greenhouse gases that have different levels of impact on global warming.

This data is available from the Chicago City Data Portal.
