This Toronto Green Standard Tier 2 and LEED® Gold Canada Candidate building includes:

Bike Storage

A total of 161 bicycle storage spaces are provided outdoors and inside the underground garage.

Electrical Vehicle Charging Infrastructure

12 parking spaces are provided for electric vehicle charging stations.

Green Roof

The green roof located at the amenity rooftop terrace features drought tolerant plant species, which reduce the need for irrigation at its source and promote biodiversity.

High Efficiency Irrigation (50% water use savings for irrigation)

High-efficiency irrigation technology was selected for installation to reduce the amount of potable water used for irrigation by 50%.

Water Efficient Fixtures and Fittings (39% better than Ontario Building Code standards)

Low-flow plumbing fixtures were selected for installation to reduce potable water consumption by 39% compared to a building with conventional plumbing fixtures. This amounts to over 8.6 million litres of water saved annually!

Construction Waste Diversion (86% Diverted)

Tridel implemented a construction waste management plan which successfully diverted 86% of all construction waste from landfill. Most of the waste generated on site during construction was recycled.

ERVs, Fan coils and Improved Air Quality

Each suite is equipped with an energy recovery ventilator (ERV). The ERV allows the delivery of fresh outdoor air directly into the suite through the vertical fan coil unit, while recovering 60-70% of the energy of outgoing air. Waste energy from stale air is used to warm up incoming air in winter and cool down incoming air in summer while recovering energy from the departing airstream and ensuring better indoor air quality for residents.

Low Emitting Materials

Low-VOC adhesives, sealants, paints, coatings, and flooring products were applied inside the building to reduce off-gassing and maintain occupant well-being.

Multi-Chute Recycling

Each floor is equipped with a sealed garbage chute room with a bi-sorter, allowing residents to easily dispose of waste, recyclables, and organics.

Efficient Lighting

Corridor and garage lights are controlled by occupancy sensors that turn lights off when areas are unoccupied. Suites are equipped with energy-efficient compact fluorescent (CFL) bulbs to maximize energy performance.

ENERGY STAR® Appliances

ENERGY STAR appliances are standard in every suite and include a stainless steel refrigerator, dishwasher and front-loading washing machine. ENERGY STAR qualified products consume 30% less energy than their conventional counterparts, which helps residents save money on electricity.

Programmable Thermostat

Residents have full control over their thermal comfort. Each suite is equipped with a programmable digital thermostat, which residents can use to control temperature and airflow in the suite. The thermostat allows homeowners to set the temperature to their comfort level when at home and adjust for increased energy savings when they are away.

Sub-metering of Utilities

Each suite is equipped with three sub-meters. The meters measure thermal energy, electricity, and hot water consumption, which means residents are only billed for the energy they use.
