There are nearly half a million multifamily units in Chicago. More than 60% of low-income individuals living in multifamily buildings in Chicago reside in buildings that are more than 75 years old. This situation presents significant potential for energy savings.
The Consortium for Advanced Residential Buildings has worked with builders to assess the most practical cost-effective means to reduce home energy consumption and approach zero energy. Especially in multifamily applications, CARB has seen more developers explore solar domestic hot-water systems as part of the least-cost pathway.
