A freshly-cleared site at 123 Portland Street in Toronto's Fashion District will soon be the home of a new 16-storey, Sweeny &Co Architects-designed luxury condominium development from Minto Communities GTA. In recent months, we've explored everything from the building's path through the planning process to its suites and its U31-appointed amenities, and now we return for a look at some of the sustainability features that will further set the building apart from other offerings in the area.

Targeting LEED certification, Minto is seeking to reduce the use of resources consumed by the building to minimize waste and cut back on greenhouse gas emissions with a variety of energy-efficient and environmentally-conscious features and practices. 

Sustainability measures will be put in place inside and out, starting with a building envelope that balances exterior glazing—enough to allow sufficient daylight to penetrate suites and common areas—with solid surfaces that provide more than typical insulation, all in the aid of energy efficiency. Up top, extensive rooftop plantings will minimize the building's impact on the urban heat island effect, while also achieving Toronto Green Standards. The green roof is one of many elements in the building's biophilic design, incorporating natural materials into the exterior and interior design.

Interior features include enhanced common area ventilation, with all amenity areas planned to be monitored with CO2 sensors while an ionized air system will significantly reduce airborne pollutants and odors. Finishes will include low volatile organic compound paints, sealants, adhesives, flooring materials and insulation to further improve indoor air quality, while building maintenance crews will use scent-free and chemical-free cleaning systems in all common areas.

Energy-saving measures are being designed into the condominium suites, including energy efficient, long lasting, and low maintenance LED lighting. While most buildings switch seasonally from heating to cooling, 123 Portland will include Variable Refrigerant Flow in-suite heating and cooling systems that can be switched back and forth regardless of the season, to be complemented by an Energy Recovery Ventilation system that filters outdoor air and maintains optimal humidity.

In the end, the measures will cut energy costs for residents and improve the overall health of the community.
