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

Bike Storage

A total of 451 bicycle storage spaces are provided at grade and inside the underground garage.

Electrical Vehicle Charging Infrastructure

137 parking spaces are equipped with roughed-in conduits for electric vehicles.

Green Roof

The green roof located on the third, fourth, sixth, eighth, and mechanical penthouse floors feature native plant species, which reduce the need for irrigation at its source and promote biodiversity.

Rainwater Harvesting (92.74m3 tank – holds 92,740 L)

A cistern collects water on rainy days and stores the water for future use. The landscaping will be watered using this harvested rainwater.

High Efficiency Irrigation (72% water use savings for irrigation)

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

Water Efficient Fixtures and Fittings (41% better than OBC standards)

Low-flow plumbing fixtures were selected for installation to reduce potable water consumption by 41% compared to a building with conventional plumbing fixtures. This amounts to over 55 million litres of water saved annually.

Construction Waste Diversion

Tridel implemented a construction waste management plan which successfully diverted 79% 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 uniquely enhanced with an Energy Recovery Ventilator (ERV) system, which allows the delivery of fresh outdoor air directly into the suite through the vertical fan coil unit, while recovering 60% 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.

Humidity Control

Each bathroom exhaust fan has an adjustable built-in humidity sensor, which turns the fan on when the humidity exceeds the setting on the switch – helping to prevent the build-up of mold and mildew.

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, and common areas are additionally equipped with LED lighting 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 use 30% less energy to do the same job as non-ENERGY STAR qualified products, saving homeowners money while creating fewer greenhouse gas emissions.

Programmable Thermostat

The fully programmable thermostat enables control of the temperature and airflow in your suite. The thermostat allows homeowners to set the temperature to their comfort level when home and adjust for increased energy savings when you are out of the suite over a 7-day schedule.

Sub-metering Utilities

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