From 2015-2018, TAF partnered with Toronto Community Housing to undertake retrofits in seven buildings on three sites. This case study looks at one of those sites, Arleta Manor. Arleta Manor is a two-building seniors residential complex in North York constructed in 1972 containing 372 apartments.
One notable aspect of the retrofit: This was the first demonstration of gas absorption heat pump technology for multi-residential domestic hot water heating in the cold Canadian climate. In the first year of operation, the heat pumps saved 10,000 m3 of natural gas and 19 tonnes of carbon emissions compared to the pre-retrofit heating system.
Key outcomes at Arleta Manor:
- 30 per cent reduction in carbon emissions
- Higher than projected utility cost savings
- Significantly improved indoor environmental quality
