The John Abbott College Library is a three-story, century-old building with a renovation project to modernize its HVAC systems. HVAC systems have been modernized to better meet the building’s heating, cooling and ventilation needs. The networking and security system has also been modernized. Our commissioning mission affects the entire project (excluding envelope). Even though we come in very late, we have carried out a concept review to ensure the operability of the system. We will carry out all stages of commissioning during construction and post-construction.

Jésus Adolescent School

The Jesus-Adolescent school was the subject of an expansion and installation of several HVAC equipment (boiler, aerothermal heat pumps, energy recovery ventilation systems, etc.). At first, Enerzam was commissioned to assist the client in the grant application process. She did an energy study to validate the conditions of the financial assistance program and followed up on the process. Subsequently the client requested that Enerzam redraft the control sequences for the expansion.

La Ruche School

EnerZam is carrying out a Re-Commissioning audit mandate at the Sports block of La Ruche high school in Magog. The building, built in 2011, is experiencing many comfort problems which led our client to ask us for an audit assignment. We study the diagnoses of all of these problems as well as the complete diagnosis of the building. We are obliged to use all of our knowledge in the sizing and operation of swimming pools (water treatment, filling and maintaining the water level, heating, cooling, ventilation, calculation of air conditioning, ventilation, dehumidification needs). We also use our knowledge in energy efficiency (geothermal energy and heat recovery) and in particular control systems to meet this mission. We therefore carried out a complete study of the HVAC installations which led to several interventions such as: reprogramming of the construction system, particularly for geothermal energy, air reblending, adjustment of schedules. The problems are resolved, the building more efficient and the customer in control of the operation

Extension - Primary School Desjardins (ASHRAE 2 N2)

The Sherbrooke school board is planning the new construction of a school integrating an existing part which will undergo a major renovation to accommodate a low temperature network.

In particular,  wants to remove the existing steam network that used to heat the school. EnerZam performed a full commissioning mission (very close to improved) for this energy saving project.

Elementary School- Butler

The EnerZam team was selected for a full commissioning mission from the design phase to site visits 1 year after the end of the work. Following an energy audit by the firm EnerZam, the school board decided to renovate the boiler room and install a ventilation system in the gymnasium at Butler Elementary School. The objective of the project is to reduce energy consumption, greenhouse gas emissions and reduce operating costs

Elementary School - Drummondville

The Eastern Township school board commissioned us to carry out a plan audit of their new elementary school in Drummondville. This new building will accommodate 300 students in a structure comprising, among other things: 22 classes, a cafeteria, a library, a double gymnasium and an administrative block. The new school was to be ventilated (fresh air distribution), heated and tempered in summer. Technically, the mechanical solution adopted is partial geothermal energy with an accumulator and an electric boiler in two-thirds redundancy which supply two water networks (north-south) and coils for preheating the fresh air in the air units of the building. gymnasium and the rest of the school. The water networks serve several fan coils (FanCoil) which guarantee the thermal comfort of the occupants in the different areas of the building.

Formation Center Paul-Rousseau

EnerZam performs a full commissioning mission (almost the enhanced level of LEED) for the expansion including commissioning of building mechanics. Note here that EnerZam team also received energy simulation missions to demonstrate compliance with the 2013-2020 PACC, drafting of the control sequences and carried out the energy audit on the expansion plan and the existing building. where EnerZam professionals have proposed the concept which is being installed at the moment.

This includes the installation of VAV boxes, balancing, the installation of 16 temperature probes, new control sequences and management of kW peaks by unloading the burner of the humidifier.

Old Zellers

The EnerZam team led a Re-Commissioning project at the Old Zeller building. The main measure of Re-Commissioning was the optimization of the cycles and modulations of the chilled water group. The Re-Commissioning was then carried out.

CBSA Saint-Stephen

The goal is to implement a continuous commissioning solution for the Canada Border Services Agency. An energy saving mission was carried out on this building one year before the start date of our service offering. So the customer did not expect us to find a problematic defect in the building. In the first report, we found 26 defects. Addressing these deficiencies would result in annual savings of $ 8,000. This result illustrates the power of our automated fault detection and diagnosis technique compared to conventional methods and insufficient data analysis in traditional energy saving missions.


Nordik Group - Spa-Nature Whitby

The Nordik group is constructing a new Spa in Whitby, Ontario using BIM design / construction. The new project includes saunas, hammams, hot (40C), medium (25C) and cold (13C) outdoor pools. The building includes massage rooms, a restaurant, changing rooms, an indoor saltwater pool. In addition to the site energy simulation and grant management, EnerZam acts as an Cx agent from design through operation using our extensive Spa expertise to steer the project in the right direction. Our tasks are very close to the improved LEED V4 commissioning by adding the writing of customer needs, participation in the design base and the detailed review of plans and specifications (including selection of equipment and control sequences), detailed review of shop drawings (not just for Cx needs) and drafting of site maintenance ranges.

Groupe Nordik - Banyä

The Nordik Spa-Nature commissioned EnerZam to commission the new Banyä building. As part of our mandate, we developed the Owner’s Project (OPR) requirements with the owner. We then carried out a first energy simulation (IES-VE software) with the 3D Architectural model and developed the design base (BOD)

Nordik - Spa-Nature

Carry out a feasibility study for the conversion of Vapor Oil Boilers, in order to take advantage of the arrival of natural gas. EnerZam has been able to meet the demand by producing the analysis necessary to substantiate and support the recommendations made to the client. The proposed recommendation (among 3 different options) proposed a reduction in GHG emissions of 53.4 tonnes of CO2 / year, by abandoning oil for natural gas and increasing the efficiency of the boilers. Our firm suggested replacing an oil-fired boiler with a condensing boiler, connected to natural gas, which could also be used for the future thermal power plant project.

Spa Nordik

The EnerZam team conducted a Re-Commissioning project at Spa Nordik. An ASHRAE level 2 energy audit was carried out to enhance energy optimization. Using dynamic 3D thermal simulation, the EnerZam team was able to more accurately assess the feasibility of performance improvement measures. The main measure was to heat the terminal loop using the Air / Water heat pump. The Re-Commissioning was then carried out.

Our team brought its expertise to the commissioning of the project as well as to identify gaps within the project and propose solutions and recommendations.

BGIS Rideau Falls

The Rideau Fall Labs building receives its heating via a district steam network and the piping is at the end of its life. In the event of a broken piping, no replacement will be made since the replacement cost would be too high compared to condensing boilers. Therefore, the project consists of replacing the existing steam-water exchangers with new condensing boilers and installing a new control system.

Canadian Space Agency

Detailed simulation of the entire building (including extremely detailed thermal zoning) and HVAC (no reference building).

Asticou Center - Energy Audit ASHRAE Level 2

Brookfield Global Integrated Solutions (BGIS) commissioned EnerZam for an ASHRAE Level 2 energy study as well as for measurement and verification. The objective of the project was to propose performance improvement measures to reduce energy consumption and reduce greenhouse gas emissions while improving occupant comfort. The client’s goal with the M&V was to establish the real energy balance of the building. The energy study and the M&V, allowed us to establish a list of performance improvement measures proposing a reduction in consumption of 22% with savings of $ 169,436 per year, a return on investment of 15 years and reduction of greenhouse gases by around 263 tonnes of CO2. We used our IES-VE simulation software to assess the effectiveness of the measures. The main measures proposed were: the addition of a geothermal system, installation of variable speed drives on the water towers, installation of solar domestic hot water preheating, addition of variable speed drives on the ventilation units, modification control sequences for the boilers in block 1100.

Swing Space - Terrasses des Chaudières

EnerZam acted as Cx agent from the design phase to the construction phase. We wrote the MCx plan and specifications; carried out all the steps of a basic Cx during the work and closure phase, in particular: Cx meeting, assisted in pre-functional tests, organize and carry out functional tests and write our Cx report, including the log of problems, validation of training and review of O&M documents. Through our MCx, we have covered HVAC equipment, control and lighting (especially emergency). We were mandated to carry out the commissioning of the HVAC systems of the new office space after redevelopment. The redevelopment 2.0 project was carried out over 3 floors at 10 Eddy, Gatineau (Qc) and covered an office area of approximately 7,500 m2. The project consisted of the installation of more than 100 VAV boxes and 6 ventilation systems with VDF as well as the reuse of existing ventilation ducts. On the lighting side, all the fixtures have changed to LED.

College of the Canada Border Services Agency

Brookfield Global Integrated Solutions (BGIS) commissioned EnerZam to conduct a study on the ventilation and air conditioning system in the Campus Block B gymnasium of the College of the Canada Border Services Agency (CBSA) .The client identified comfort in both humidity and high temperature, summer and winter. We must also ensure that the installation and its new use comply with the fresh air code.


Brookfield Global Integrated Solutions commissioned EnerZam to carry out a study aimed at improving the water make-up preheating of the two steam boilers supplying the humidification ramps of the building’s air handling units. Premature wear has been observed on this equipment with replacement every 2 years for at least 15 years according to building staff. We noticed that the 16th district steam boiler was in high demand and we saw an opportunity to save energy by recovering the heat discharged by the combustion gases.

SQ Sherbrooke Headquarter

The firm EnerZam was mandated by the SQI to carry out a refurbishment audit (RCx) on the building “Édifice Bertrand-Fabi” located at 40 Don Bosco Sud in Sherbrooke. EnerZam studied the heating, air conditioning and ventilation systems as well as the centralized control system in order to present several measures to improve performance. EnerZam will be present during the implantation, transfer and 24-month and 48-month follow-up phase.


Jewish Rehabilitation Hospital

The Jewish Rehabilitation Hospital has several control systems for its mechanical equipment. For the oldest system, Auto Energy Company, the hospital does not yet have “Final As Built Plans” (TQC) of the control network. The Laval Integrated Health and Social Services Center commissioned Enerzam Inc. to prepare an estimate for the development of TQC control plans.

CHSLD-La Pieta

The EnerZam team commissioned the geothermal system at CHSLD La Pieta for the CSSS de Gatineau. It had never been operational since its installation. The mandate included commissioning the system in heating and air conditioning mode, reviewing the design, defining the scope of work and functional phases. We therefore carried out the calculations necessary to validate the selection of equipment and then carried out site visits to ensure the conformity of the work. We also validated the balancing reports. Finally, we were able to carry out the functional tests with the control contractor in 2 stages (1 for the heating season and 1 for the air conditioning season). A few deficiencies were raised and subsequently corrected. The geothermal system is now operating as it should.


The CISSS de Laval mandated the firm Enerzam to review the report of an SEA and issue a conciliation report for this project. The objective of this report is to present to the ESE the position of the CISSS de Laval concerning the reconciliation of the energy savings of the project at the end of year 2. This analysis has highlighted certain differences in the interpretation. of the contract for construction savings. As an external energy efficiency professional, EnerZam has had to address certain knowledge gaps in this area on the part of the SEE. We were able to identify some shortcomings; maintenance savings recorded during the installation phase, energy savings recorded in the reconciliation of the first two years, the SEE uses the pre-project efficiencies and tariffs, adjustments (which lower consumption) not considered in the report presented by the SEE. Our expertise in this project will have enabled the public body to have an accurate picture of the situation of its project. The conciliation made by EnerZam will also have made it possible to maintain a good climate between the different parties.

Gatineau Hospital Emergency

The EnerZam team carried out a recommissioning project at the Gatineau hospital for the CSSS de Gatineau. Opportunities for energy savings have been found in the new construction of the ER. There were flaws in the way the design check worked. The EnerZam team also found great potential for energy savings through re-engineering of control sequences and suggestions for retrofitting energy recovery systems at Fluace Hospital. Many other opportunities for improved control have been found, involving all HVAC installations. We were also mandated for the Commissioning of the 2 implementation phases. Our project manager managed the coordination of sub-contractors (control and balancing) and ensured that customer requirements were met. With the help of this tool and the expertise of the EnerZam team, the client had access to a continuous commissioning approach that pushed their buildings towards excellence and guaranteed them a persistence of energy saved. EnerZam provided engineering service on a monthly basis using this tool through the continuous optimization operation and Measurement and Verification (M&V).
