HVAC systems continue to be the most challenging part of a new construction project to get right the first time, and the most challenging parts of the HVAC systems are their controls. I believe there are two root causes.
Intra-project team member communication and coordination (#1 above) has been a recurring theme in my columns. This month, I would like to address the level of review and coordination that needs to be focused solely on the HVAC controls during the construction phase in order to improve the chances of the control systems performing as required when functionally tested during the acceptance phase.
