McKinstry’s Geremy Wolff has learned some useful lessons during his 12 years in the commissioning game. Two key lessons:
- Nobody knows everything. Though the commissioning team has broad skills and experience, they can also call on experts from across the McKinstry organization for help. If that’s not enough, expert subcontractors are brought in to bridge any gaps.
- Things change. A decline in HVAC system performance is often traced to seemingly minor adjustments, alterations and breakdowns that accumulate over time. AC is turned on for a “one-time” weekend meeting—and never reset. A damper fails. A cold-sensitive building occupant turns the heat up and to compensate the occupants next door turn thermostats down, leaving the building at war with itself. In-depth detective work and careful measurements of temperature, humidity, outside air (CO2), air flow, power consumption and more are needed to discover and work through such issues.
