Mechanical Systems Upgrades Design


Fort. Saskatchewan, AB




Clark Engineering was retained by Johnson Controls Canada to review the existing heating, ventilation, and air conditioning (HVAC) systems at a chemical processing facility’s administration building in Fort Saskatchewan, Alberta. The existing HVAC systems were unable to maintain consistent or comfortable temperatures throughout the building.

Through visual inspections and detailed design recommendations, Clark Engineering was able to recommend upgrades to the administration building HVAC systems that would not only improve indoor comfort, but would improve indoor air quality, energy efficiency, and HVAC system performance.


  • Existing rooftop HVAC units at end-of-life were replaced with modern, energy efficient equivalents
  • HVAC controls were replaced with a building management system to allow better equipment scheduling, improved system control, and system wide setpoint adjustments
  • The supply air distribution systems were extensively reviewed, documented and reconfigured to repair zoning as required. Improperly installed electric zone reheat was removed. VVT damper operators were installed to provide additional comfort control

The review and recommendations phase was completed in early 2019 with the detailed design and construction phases occurring in late 2019.
