Prism conducted a cost-benefit analysis of implementing energy conservation measures (ECMs) across 200 of BC Housing’s buildings.
The analysis involved:
- Reviewing ECMs identified from ASHRAE Level II audits of 25 BC Housing Multi-unit Residential Buildings (MURB)
- Categorizing ECMs applicability by building archetype (e.g. electrical vs. natural gas heating and hot water)
- Analyzing ECMs applicability by BC climate zone
- Summarizing average cost of implementation and estimated energy reduction potential by floor area or by number of suites or by building as applicable
- Characterizing 210 buildings by vintage built-year, building archetype, and climate zone
- Extrapolating ECMs across the 210 buildings, as per applicability
- Incorporating into the future modelling of cost and emission reduction the caveat that buildings would be re-developed as net-zero new construction 60 years after built-year
- Summarizing results in a report and presentation for BC Housing
This analysis provided BC Housing insight in the cost-benefit analysis of the energy conservation measures to enable planning towards achieving their 2050 emission reduction targets.
