The Impervious Surface 2021 dataset is a collection of polygon features derived from Calgary Digital Aerial Survey mapping linework which have been determined as impervious. Impervious surfaces are defined as any material which will seal the soil surface, impede water infiltration, collect solar heat or deprive tree or vegetation roots of aeration. Impervious surfaces effect many aspects of our City, including storm run off volumes, pollutant concentrations and drainage. The City must understand and manage the amount of impervious surfaces carefully to ensure the ongoing health and vitality of the municipality and the environment.

HVAC or Mechanical permits are issued for the installation, addition or alteration of a heating and ventilation system. Permits must be obtained and inspections completed prior to occupying the space the equipment is servicing. If there are any unresolved building code deficiencies or not acceptable outcomes, contact the permit holder for more information or contact 311. See Mechanical Permits for more information.

The Forward Sortation Area Boundary File depicts the boundaries of forward sortation areas (FSAs) derived from postal codes captured from federal census questionnaires. This is based on census dissemination areas. The file is periodically updated, following the federal census which is currently mandated every 5 years (2011, 2016, 2021...).

“This dataset contains building energy and greenhouse gas emission performance information for a subset of properties owned and operated by the City of Calgary. All energy and greenhouse gas emission metrics are calculated by ENERGY STAR Portfolio Manager using monthly, whole-building energy consumption data billed between January 1st and December 31st.

All blank cells in the dataset correspond to data points that are "not available" because they do not exist or cannot be calculated.”
