  1. Sustainable Site
    Urban Redevelopment:
    Optimizing existing infrastructure.
    Alternative Transportation:
    Within close proximity to the subway, covered storage for bicycles and walking distance to shopping and amenities. Car share program.
    Rainwater Collection:
    This harvesting system meets the building irrigation needs naturally with rainwater instead of with drinking water.
    Heat Island Effect:
    Reduces thermal gradient differences between developed and undeveloped areas by locating 100% of parking underground.
  2. Energy and Atmosphere
    Significant Energy Savings:
    Designed to be 40% more energy efficient compared to Model National Energy Code for Buildings exceeding the 25% required by CBIP (Commercial Building Incentive Program).

    Measurement and Verification:
    Sophisticated building automation system will continually monitor building mechanical systems and utility bill analysis ensuring ongoing accountability and optimization.
    Green Energy:
    Minto has committed to green power equal to 100% of common element electricity for two years and 100% of suite electricity for one year.
    Motion Control Lighting:
    Installed in common areas including parking garage and stairwells ensure the lights are off when not in use.
    Solar Energy:
    Renewable passive solar energy uses daylight to preheat corridor air.
  3. Occupant Empowerment
    Simple and convenient ‘all-off’ in-suite lighting control in each suite. One flick of a switch turns off all fixed lighting and exhaust fans.
    Smart Metering:
    These sub meters measure hour-by-hour individual usage so that you pay only for what you use, putting the savings into the resident’s pocket.
    Front loading washing machines and Energy Star appliances help reduce energy consumption and costs for residents.
    Compact Flouresent Lighting:
    CFL’s have been installed where applicable, in the suites, reducing energy comsumption.
    Water Conservation:
    Each suite will be individually metered for hot and cold-water use, putting water management in the hands of the user. Past developments have demonstrated this initiative reduces water consumption by over 50% in comparison to a typical multi-residential building.
    Dual Flush Toilets:
    Equipping each suite with dual flush toilets will lead to an additional 32% reduction in water conservation.
    Collection of Recyclables:
    Minto is continually looking for ways to encourage residents to recycle. Minto Roehampton will be equipped with a multi stream garbage disposal system that allows for easy recycling on every floor and will accommodate future organic recycling.
  4. Materials and Resources
    • Regionally Produced and Recyclable Materials:
    Minto Roehampton will incorporate regionally manufactured materials.
    Low Emitting Materials:
    Environmentally friendly underlays, laminate and ceramic flooring and low toxicity paints significantly reduced volatile organic compounds.
    Construction Waste Management:
    Minto has implemented a rigourous construction waste management program that will separate metals and cardboard and result in over 75% of waste being diverted from landfill.
  5. Indoor Environmental Quality
    System Controllability:
    Each suite features a fully user networked adjustable air flow and temperature control that features fully automatic motion sensor control with manual override for maximum savings and verifable comfort.
    Daylight and Views:
    Generous use of low-e thermal glass with operable windows maximizes
    natural illumination and ventilation while taking advantage of the magnificent outward views.
    Healthy Living:
    MintoInspired HRV fan coil installed in every suite to recover exhaust heat and directly deliver fresh filtered air. The design uniquely allows the fresh air to be circulated throughout the suite, reducing dust and particulates.
