What our customers are saying

  • City of Markham chose Efficiency Engineering

    It’s been a pleasure working with EE.  EE’s expertise in HVAC design and energy optimization technology will contribute greatly in the operation of our Theatre facility, by reducing utility costs, meeting sustainability goals and reducing its greenhouse gas emissions.  We use EE because we know they will assess our project and strategic goals effectively and turn them into construction-ready documents.  We especially appreciate the professionalism and conscientiousness of EE throughout the implementation phase, quickly assessing submitted contract administration and helping to keep schedule on track.  When unanticipated site conditions presented themselves, they were quickly dealt with by EE, through great team communication channels.

  • “Housing Cambridge engaged Efficiency Engineering to complete an energy audit for a 72 unit multi-residential building at 59 Cedar Street North, Kitchener.  Efficiency Engineering staff were very professional and great to work with.  They worked to a tight timeline to complete the audit.  Their report was comprehensive and provided an excellent basis for prioritizing capital investments in order to make the building more energy efficient and to reduce overall operating costs.”
