80 Dale
80 Dale is a 12-storey multi-unit residential building located in Scarborough, Ontario. The project is targeting CaGBC Zero Carbon Building Standard, the Canada Mortgage and Housing Corporation (CMHC) — Co-op Housing Development Program Accessibility and Energy Efficiency Attestation Criteria (Option 2), and Fitwel Certification.
The site is in very close proximity to the Guildwood Go Station, which presents a valuable opportunity to provide affordable housing within walking distance to existing public transit.
The building itself contains 285 dwelling units with the following counts: 69 studio units, 135 one-bedroom units, 66 two-bedroom units, and 15 three-bedroom units, with 45 barrier-free units. The units are designed with great attention to accessibility, affordability, and inclusivity. A variety of interior and exterior amenity spaces are also provided to meet the expected diverse needs of future residents.

SITE DESIGN
site plan
The site is located on the northwest edge of the Scarborough Village neighbourhood, bordered by the Metrolinx rail corridor to the north and Kingston Road to the southeast.
One of the primary design intents for the site plan is to create a direct pedestrian connection to the Guildwood Go Station in its proximity, most likely on established desire paths going under the Kingston Road Bridge. The intent is that this pathway would connect to POPS (Privately Owned Publicly Accessible Space) that lines the north and west edges of the proposed site plan. Not only will the pathway provide 80 Dale residents direct pedestrian access to the Guildwood Go Station, but it will also connect two neighbourhoods that are currently bisected by Kingston Road. The POPS area includes a generous, maintained pathway, greenery and trees, benches, refuse bins, and lighting. In addition to the POPS, the site design proposes a variety of natural features including an infiltration swale with native vegetation, a natural water retention pond, and verdant new tree plantings.

HIGH-PERFORMANCE ZERO CARBON SYSTEMS
GEO-EXCHANGE HEAT PUMP
LOW-CARBON CONCRETE
DILIGENT THERMAL CONTROL
AFFORDABLE HOUSING
The design exhibits the advantages of highly integrated systems. Not only does operational energy and embodied carbon reduce significantly, so does capital cost. The result is a high performance, zero carbon subsidized affordable housing complex.
Demonstrated by the low TEDI, the basis of the integrated systems is the advanced thermal performance of the enclosure design. Diligent specification of continuous exterior insulation combined with careful detailing of component interfaces results in highly effective thermal control and high airtightness.
The heating and cooling system is a geo-exchange decentralized water source heat pump. Ventilation is decentralized in-suite ERVs. The system is optimized to the performance of the enclosure. The structure of the building is also the outcome of an approach to lowering emissions. It is cast of low carbon concrete; and structural framing was rigorously planned to avoid transfers, resulting in significant reductions in embodied carbon.
