Energy and Greenhouse Gas Emission Savings

We looked at more than 80 City of Calgary projects completed up to 2025 to see how much energy and money they save, and how they reduce greenhouse gases (GHGs). We looked at more than 30 additional major projects that will be completed by 2030 to estimate how energy costs and GHG emissions will change in the future. We used energy models to estimate the savings. We also considered changes in utility costs and GHG emissions over time. The City of Calgary uses reports from the Government of Canada to calculate GHG emissions.

Energy codes have changed over time, and a unique energy model is created for each building. The predicted savings might not match what actually happens after the project is built. We didn’t check these savings with detailed monitoring. Solar panels added to the buildings later are not included in the graphs.
