Title: Energy and Water Use Benchmarking for Certain Properties in Des Moines

Date Passed: June 3, 2019

Policy Language: Ordinance 15,779

Summary: Des Moines, Iowa joined the ranks of some of the most sustainability-conscious cities in the Midwest when the city council adopted a benchmarking ordinance on June 3, 2019. The ordinance will require all city-owned buildings and privately-owned commercial and multifamily buildings larger than 25,000 square feet to report their energy and water usage to the city. Currently, large buildings in Des Moines account for 56% of greenhouse gas emissions, and this initiative will aid in the city’s goal of reducing their emissions 28% by 2025.
