In-depth knowledge of HVAC system design including air handling units, packaged HVAC units, exhaust and ventilation systems, pressurization systems, and specialty systems for hazardous or classified areas.
Working knowledge of applicable codes and standards such as ASHRAE, NFPA, CSA, SMACNA, and relevant provincial and national building codes.
Experience with HVAC design tools and calculation software (e.g., HAP, Trace, Elite, or equivalent) is considered an asset.
Experience supporting brownfield projects, retrofits, revamps, and facility expansions is considered an asset.
