On June 3, 2019, Des Moines adopted a mandatory benchmarking ordinace by a city council meeting 5-2. Since large buildings account for 56% of greenhouse gas emissions in Des Moines, this initiative will support the city's efforts to cut their emissions by 28 percent by 2025.
The law requires commercial, muiltifamily, and city-owned buildings over 25,000 square feet to benchmark annually. An estimated nearly 800 buildings will be required to report their energy use by June 1, 2020. The results of this reporting will be made public by 2022, and all buildings that have an ENERGY STAR score below 75 will be identified online. However, owners of these low-performing bulidings can keep their data private if they commit to a performance improvement path.
