Vision - Process Cooling

In order to meet the increase of production need, Vision decided to extend their existing facility. A new engineered solution of 650 Tons (2.4 MW) of cooling was designed to lower the energy costs of the new process cooling system. As a result the total number of pumps was reduced by 3 versus previous design. This translate to $ 40.000 saving of initial capital cost plus $ 300.000 energy saving over the plant life time. To further reduce the overall annual energy consumption the free cooling feature was added too. The latest generation of control and monitoring system ensures that the savings continue longer after initial commissioning process. A complete 3D optimization of the mechanical room piping and equipment layout was done previous of construction phase. This optimization lead to a considerable reduction time for site construction, giving the possibility to start to install the equipment as arrives on site.

Some of the feature include the following:

  • reduce the number of totals pumps by 3
  • a complete 3D optimization of the mechanical room
  • full capability of remote control and diagnostic
  • two years data base of all parameters
  • custom service and energy reports



    • Arctic - AHRI Test Stand

    Computer selection programs predict chiller performance based on laboratory testing. Factory performance tests confirm that the actual chiller performance matches the predicted performance. A chiller performance test-stand was designed that allow a water cooled chiller to be testes in accordance with AHRI 550/590 specification. Also part of the design scope was a data acquisition system that record all the data every 14 seconds and generate the AHRI required report. Customers can connect remotely to the test-stand and by controlling the test-stand set-points can simulate true field conditions and observe the chiller performance. Energy that comes into system must equal the energy that comes out so the energy balance calculations confirm the test validity. The test-stand was certify as "AHRI certified" by third party.



    Fire Station - Georgetown South Station

    The South Fire hall is approximately 12,500 ft2 (1,160 m2) with offices, meeting rooms, training room, kitchens, admin support areas, an apparatus bay for 4 fire trucks and support areas for equipment and for building services. A recommissioning investigation was undertaken to provide a room-by-room calculation of heating and cooling loads to determine if conditioning equipment and the in-floor heating is correctly sized to match the load. The commissioning report also reviews equipment installed as per the drawings, specifications, and change orders.



    Citi Bank –123 Front Street

    A recommissioning investigation was completed for this 39,600 m2 Oxford Properties office facility in Toronto. Proposed recommendations identified by the investigation are being implemented to attain improved energy efficiency and conservation. As part of this recommissioning project, savings close to $100,000 have identified with a simple payback of 11 months .

    Sample improvements identified include the following:

  • implementing a strategy to optimize outdoor air quantities
  • upgrade DCW booster pump control
  • installing variable speed pumping for the heating system
  • implementing and optimizing a series of building automation control routines, such as night set-back, optimum equipment start/stop , humidity reset, and outside air free cooling optimizing domestic cold water booster pump operation



    • Menkes – 5000 Yonge Street

    Building assessment, recommissioning, building envelope review, and LEED EB:O&M certification services support this large property owner’s desire to improve the environmental sustainability of their building portfolio. Key sustainable strategies of this 50,700 m2 office building include low-flow plumbing fixtures, water efficient landscaping, improved indoor air quality, and the implementation of sustainable operation policies.



    Brantford Union Gas

    In support of LEED EB:O&M certification, a recommissioning investigation was provided for this 4,200 m2 office building. Recommendations for no cost/low cost measures were provided to improve operations and energy efficiency. Key measures include adjusting heating and cooling schedules to reflect occupancy, correcting control sequences, and verifying proper operation of control device programming.



    Armatec

    Completing a recommissioning investigation with schematic design support, as required, to improve HVAC operation and incorporate a ground source heat pump system. Objectives include improving energy efficiency, addressing spring-fall changeover problems, increasing spring cooling performance to offices, optimizing contribution of floor heating, and adding heat pump capacity
