Toronto Sustainability

Our office is certified LEED® CI Gold

As a leader at incorporating sustainability at all levels of development – from city planning to transportation to buildings – MMM Group Limited designed its Toronto office with green strategies in mind. Using in-house expertise, MMM Group achieved LEED CI Platinum for this office to demonstrate how ensuring environmental responsibility and creating a comfortable, modern office can work seamlessly together.

  • Sustainability_office_Toronto_CaGBC_plaque_gold_2013LEED (Leadership in Energy and Environmental Design) is the premier green building rating system in North America.

    Overseen here by the non-profit Canada Green Building Council, LEED awards points to projects that meet certain sustainability requirements in the following categories: Sustainable Sites, Water Efficiency, Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality, Innovation & Design. The number of points a project receives determines the LEED level awarded: Certified, Silver, Gold, Platinum. The LEED CI (Commercial Interiors) rating system is specifically designed for office fit-ups in tenanted buildings, such as this office which occupies one floor of a ten-storey building.

    Making sustainable choices when it comes to materials can reduce the harvesting of virgin materials, decrease carbon emissions, and reduce waste. In this office, every effort was made to select such materials during the design and construction process.


    Recycled Materials: In this office, 24% of materials contain high levels of recycled content. This includes chairs, workstations, insulation, dry wall, steel studs, and “marmoleum” (a linseed-based linoleum flooring product).



    Regional Materials:  Over one-third of all materials used in this fit-up are from local sources. This not only supports the local economy, but decreases the carbon emissions associated with transporting materials to the construction site.



    Reused Materials: Over half of the chairs, cabinets, and meeting room tables in this office were salvaged from MMM’s previous office to reuse here.




    Certified Wood: All wood used in this office is Forest Stewardship Council (FSC) certified. FSC wood is from forests that are maintained and harvested according to the highest environmental standards.




  • office_3Green offices aren’t just better for the environment, but for the people that work there, too. Indoor air quality, ventilation effectiveness, and access to natural light are all areas addressed by LEED.

    Sustainability_office_Toronto_ComfortableSpace_daylightingDaylighting: Access to natural daylight has been shown to improve worker health and productivity. All partitions in this office are 42° or lower. This allows more natural daylight penetration. In fact, 90% of all spaces in this office have access to daylighting and views to the outdoors.

    Low-Off-Gassing Products: Volatile organic compounds (VOCs) are found in many common construction and office fit-up products, such as furniture, paint, and flooring. However, unhealthy VOCs off-gas from these products – harming indoor air quality.

    All materials used at this office are “low-VOC.” This includes paints, sealants, adhesives, coatings, wood products, laminates, and carpet.

    Green Housekeeping: This office, and the entire building, has a green housekeeping program in which EcoLogo and healthy cleaners are used to maintain superior indoor air quality.


  • office_71Lighting is one of the major energy users in most offices, and decreasing the lighting power density of a space is one of the main ways to achieve points under the LEED for Commercial Interiors green building rating system. Lighting power density refers to the amount of energy (in Watts) used for lighting in a given floor area (usually expressed in square metres).


    The lighting power density of this office is 8.3 W/m2 – 30% less than that of a conventional office. This was achieved through replacing existing, inefficient fixtures with T8s (high-efficiency lighting ballasts) and low-mercury LED fixtures. Additionally, daylighting and occupancy sensors were installed to dim or turn off lights when possible. The advanced lighting control system allows individual light level control in open office areas to enable individuals to optimize lighting power to match specific needs and reduce the overall lighting requirements overall.

    An energy recovery ventilation system was added to the office space to reduce the amount of energy needed to heat or cool the incoming fresh air. The photocopy room, kitchenette, shower/changeroom facilities, and mechanical server room (rooms with potentially poor air quality and odours) have a continuous exhaust system.

    All equipment and appliances in this office are Energy Star rated. This North American rating is for electronics that meet high energy efficiency standards.

  • Sustainability_Infographs_R6Thousands of litres of treated, potable water are wasted every year in offices due to inefficient toilets and urinals.

    During the retrofit of this office space, all toilets and urinals were replaced with low-flow fixtures that use less water. This helped create a 58% water use reduction in the tenant space and a 40% reduction in the base building’s water use as well.
