The Village of Oak Park's benchmarking ordinance applies to buildings larger than 10,000 square feet in Gross Floor Area (“Covered Buildings”). This is expected to be approximately 250 Oak Park buildings. Residential buildings with less than four units are exempted from this policy.
Every year, Covered Buildings will report their total energy use for the previous year, for the whole building. Energy use for individual tenants will not need to be reported separately. The data will be reported through the U.S. EPA’s free online tool, Portfolio Manager. Every three years, the Covered Building reports will be reviewed to ensure data quality.
The following year, the Village of Oak Park will publicly report the Building Benchmark report data, including Energy Star scores for the Covered Buildings. This allows the recognition and reward of buildings with superior energy performance.
