The aim of the HVAC system is to keep the buildings’ inhabitants comfortable and healthy while considering system costs. When designing and installing multi-floor supply and exhaust systems, balancing can become an issue.  Fan pressures and thermal stack affects can cause differences in how much supply/exhaust air each floor experiences.  When spaces experience the incorrect amount of supply/exhaust air it can affect the...
