Additional information

We looked at 70 City of Calgary LEED projects certified up to 2023 to see how much water they save and how much construction waste was diverted from landfill. We used information from when the projects got LEED certified to produce these charts. LEED rules and baselines can be different for each project. The predicted savings might not match what happens after the project is built.
