Existing Building Commissioning (EBCx) is a term that refers to the process of testing an existing facility’s systems and equipment to ensure they are still functioning as designed and intended and, if not, make the necessary adjustments. Although comfort problems are the initial reason why Existing Building Commissioning projects are conducted, such projects are also critical in focusing on how the building various systems and components operate together and how operations can be improved.

Increasing occupant comfort and satisfaction while reducing energy operating costs are powerful ways to unlock value in your building assets. It has been well documented that the practice of EBCx reduces operating costs while improving indoor environmental quality.

This Introduction to Existing Building Commissioning program provides participants with a practical approach to EBCx with a specific focus on the elements of a robust investigation. The course leverages a number of real-life examples of successful projects as well as case studies from a variety of commercial and institutional building types. Additionally, a major focus is placed on the operational efficiency of systems – particularly HVAC and control systems.

Michel Parent, CIET Canada, headshot
Michel Parent
Eng., M.Sc.A.

Michel Parent has a Bachelor’s (Laval – 1986) and a Master’s degree (Waterloo – 1988, Solar Energy) in Mechanical Engineering. From 1988 to 1990, he was in charge of the Solar Laboratory at the National Institute of Scientific Research in Varennes. He then joined the Energy Group at the Industrial Research Center of Quebec from 1991 until 1996. Since 1996, M. Parent is a partner in a consulting engineering firm, Technosim, specializing in energy efficiency. Technosim has offices in Quebec and Ontario.

Mr. Parent is specialized in energy efficiency in the commercial, institutional and industrial sectors. He has performed numerous audits across North America, which were used in developing long term energy management plans. Mr. Parent is an Existing Building Recommissioning (EB Cx) Agent and has performed recommissioning for over 5 million square feet of office and retail properties across Canada. He is a certified Existing Building Commissioning Professional (EBCP). Mr. Parent is a lead trainer for the Advanced Recommissioning Course developed for the Canadian Federal Government. Mr. Parent is also a Certified Measurement and Verification Professional (CMVP) and has developed and implemented many M&V plans compliant with the IMPVP standard. He has also worked on M&T projects implementation to ensure continuous improvements to building efficiencies within the context of his EB Cx projects. Mr. Parent has developed training modules for large corporate clients to ensure persistence of savings following EB Cx projects as well as ongoing improvements. Mr. Parent was also retained by OEE to develop and pilot the introductory recommissioning courses. Mr. Parent is also recognized as an expert energy simulator by LEED and has performed many LEED simulations as well as third-party reviews of energy simulations. Mr. Parent has performed over 100 reviews of EE4/eQuest simulations, including many required for LEED submissions. Mr. Parent is a recognized LEED technical reviewer. He is one of the three trainers, recognized by the Office of Energy Efficiency (OEE), in the use of the simulation tool EE4 used for LEED applications. Furthermore, he was contracted by Natural Resources Canada to evaluate the possible adaptations and usefulness of using Portfolio Manager within the Canadian market as a recommissioning tool.

Mr. Parent has been involved with RETScreen since its initial development. He has been in charge of developing the ground source heat pump module for RETScreen as well as being a technical reviewer for the solar (air and water) heating module, the wind energy module and photovoltaic modules of the initial versions of RETScreen.
