Across the country in large cities, buildings often account for the majority of energy use and carbon emissions.

In effort to create a more energy-aware community and reduce energy waste, the Des Moines City Council passed on June 3, 2019, the Energy and Water Benchmarking Ordinance requiring owners of buildings 25,000 sq. ft or larger to benchmark their energy and water usage.
