Rank postal codes by normalized thermal intensity within structure type groups. Identify priority neighbourhoods for retrofit incentive targeting.
Visualize which postal codes are flagged as priority vs. non-priority.
How sensitive is the ranking to the assumed basement heating fraction and floor height?
If the screening is refreshed annually, changes in postal code thermal intensity can serve as a macro-level M&V signal for neighbourhood-scale retrofit programs.
Summary: The screening identified the top quartile of postal codes by normalized thermal intensity within each structure type group. These neighbourhoods represent the strongest candidates for targeted retrofit incentive programs — where building envelopes are underperforming relative to their building stock characteristics, and where incentive dollars are most likely to produce measurable gas savings.
