Green Buildings Priority Stream – Constructed Building Performance

About this dataset

This dataset provides project‑level information for completed buildings participating in the City of Calgary’s Green Building Priority Stream (GBPS). Each record represents a single building permit for a project that has reached construction completion and includes key building characteristics such as entry pathway, floor area, construction value (where disclosed), and modelled energy, greenhouse gas (GHG), and energy cost performance based on documentation submitted at the building permit stage. The dataset includes residential and non‑residential buildings completed between 2022 and the current date, covering multiple performance pathways, including NECB‑based compliance, Net Zero Ready Homes, Net Zero Homes, and Zero Carbon Buildings. Projects that are currently under development or permitted but not yet constructed are not included. As a result, the dataset represents a subset of total GBPS participation and does not capture the full pipeline of projects enrolled in the program. All energy, emissions, and cost values reflect proposed or modelled design performance at the time of permit and may differ from measured operational outcomes once buildings are occupied. The dataset is intended to support program reporting, research, and high‑level policy evaluation, rather than project‑specific compliance verification. The data is subject to the following considerations: 1. Emissions Factors Electricity emissions factors reflect Alberta’s grid mix and may change over time. The natural gas emissions factor (0.054 tCO₂e/GJ) represents a standard combustion value. 2. Energy Costs Energy costs are based on estimated blended electricity and natural gas rates anchored to 2025 values and indexed across other years using a constant annual escalation rate. These estimates may not reflect current or site‑specific utility tariffs. 3. Solar PV Solar electricity is valued at an energy‑only rate and does not offset the full blended electricity rate. No premium export programs or solar club rates are assumed. 4. Modelled Performance Energy, emissions, and cost results are derived from energy modelling and may differ from actual building performance due to operational, weather, and occupant factors. 5. Reference Buildings Percentage savings are calculated relative to a code‑minimum reference building (NBC‑AE 2023 or NECB 2020) and represent estimated, not guaranteed, performance. 6. Data Completeness, Currency, and Use Construction value and other project attributes are self‑reported at the time of permit submission and may be incomplete or withheld for some projects. This dataset is provided “as is” and reflects information available at the time of publication. Data and assumptions may be updated periodically as additional completed projects become available or methodologies are refined.
