This project aims to assign energy systems archetype names to Montreal buildings.
|
|
The random assignation is based on statistical information extracted from different sources, being:
|
|
- For residential buildings:
|
|
- SHEU 2015: https://oee.nrcan.gc.ca/corporate/statistics/neud/dpa/menus/sheu/2015/tables.cfm
|
|
- For non-residential buildings:
|
|
- Montreal dataportal: https://dataportalforcities.org/north-america/canada/quebec/montreal
|
|
- https://www.eia.gov/consumption/commercial/data/2018/
