Green Rehab: Making Century-Old Brick Buildings Sustainable

A six-percent upfront investment reduced energy consumption by 19 percent — and carbon emissions by 34 percent — in a pair of 100-year-old brick buildings. Add solar panels and those numbers drop to 39 percent and 65 percent.

These are among the findings of an ongoing experiment conducted by students, faculty and staff at Washington University in St. Louis. The architectural equivalent of a twin study, the project centered on the gut-renovation and subsequent energy monitoring of two university-owned, World’s Fair-era apartment buildings.
