Kitchener Sustainability

Our office is certified LEED® NC, CI, and EB:O&M Platinum

As Canada’s premier green building consultants, MMM Group Limited, designed its Kitchener office to be the most energy-efficient office in Canada. Using in-house LEED, energy modeling, and M/E design expertise, we created an office that uses 69 kWh/m2 (compared with the Canadian office average of 394 kWh/m2.

  • Sustainability_office_Kitchener_CaGBC_plaque_platinum2013LEED (Leadership in Energy and Environmental Design) is the premier green building rating system in North America.

    Overseen in Canada 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, and Innovation & Design. The number of points a project receives determines the LEED level awarded: Certified, Silver, Gold, or Platinum. There are several rating systems to address the needs and goals of different project types. This office received certification in the New Construction, Commercial Interiors, and Existing Buildings: Operations & Maintenance rating systems to become the first triple LEED Platinum certified building in Canada.

  • Sustainability_office_Kitchener_Materials_lobbyMaking 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.

    Sustainability_office_Kitchener_Materials_recycled-300x200Recycled Materials:  In this office, 40% of materials contain high levels of recycled content. This includes chairs, workstations, insulation, dry wall, porcelain floor tiles, carpet, and steel studs.



    Sustainability_office_Kitchener_Materials_local_sources1Regional Materials: One-quarter 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.



    Sustainability_office_Kitchener_Materials_salvaged_materialsSalvaged Materials: The stone cladding on the building exterior was salvaged from a local church demolition. The stone in the landscaped retaining wall was salvaged from the demolition of the St. Clair River Tunnel in Sarnia. The wood floor in the lobby was salvaged from a demolished Toronto building.


    Sustainability_office_Kitchener_Materials_fsc_certifiedCertified Wood: Ninety percent of the 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.


    Sustainability_office_Kitchener_Materials_waste1-300x187Construction Waste Diversion: During construction, waste was carefully separated into separate bins so that recyclable materials could be sent to recycling facilities. As a result, 89% of waste was diverted from the landfill.



  • Sustainability_office_Kitchener_ComfortableSpace_workstationGreen 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.


    Daylighting: 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, 98% of all spaces in this office have access to daylighting, and 99% have access to views of 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.

  • Sustainability_office_Kitchener_SmartEnergy_solarHeating / cooling, ventilation, and lighting are the largest uses of energy in modern offices. This office minimizes this energy use by separating the ventilation system from the heating / cooling system (so temperature changes can be made without using ventilation fans), and controlling these systems and lighting with occupancy sensors.


    Heating and cooling are supplied by a variable refrigerant flow system where three rooftop air-source heat pumps are connected to a few dozen fan coil units throughout the space. Fresh air is brought in through an underground concrete tube, called an Earth Tube, which pre-heats or pre-cools the air before it is send to an energy recovery ventilation unit to receive heating or cooling from outgoing ventilation air. Occupancy sensors throughout the office spaces and meeting rooms determine which spaces need heating / cooling and ventilation.

    The lighting power density of this office is 8 W/m2 – a more than 35% energy savings compared with a conventional office. This was achieved through replacing existing, inefficient fixtures with T8s (high-efficiency lighting ballasts), and through the use of daylighting and occupancy sensors which dim or turn off lights when possible.

    Also, there are 5.5 kW of photovoltaic solar panels on the roof.

  • Sustainability_office_Kitchener_WaterWise_water1Thousands 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. A 5 m3 underground cistern stores rainwater from the roof and uses this water to flush toilets. This helped to create an 89% reduction in indoor potable water use rover a conventional office, and a 100% outdoor water use reduction due to native species landscaping which requires no irrigation.
