As buildings have become tighter with improved building envelope systems and inoperable windows to minimize energy use, IAQ and IEQ have become primary considerations for professional engineers and architects.

A rationalization of 'we’ve done it this way all the time' doesn’t make something right or ethical.

Whether it be enhanced air particulate filtration with higher MERV ratings; increased outside air volume; or other technologies, such as UVC, the focus is clearly on protecting students and teachers.

Engineering plays a definitive role when it comes to establishing the functional requirements of an occupied or unoccupied space’s supply air methods and devices. 

Professional engineers and architects have legal responsibilities and liabilities as dictated by state statutes. 

HVAC product selection is not as easy as it sometimes seems. For sure, the key part of engineering is the KIS principle (Keep It Simple).

What risks are being taken to not measure/monitor/control airflow directly and who is at risk?

Controlling the flow in an HVAC hydronic system can be simple or it can be complex depending on the design intent.

Whether we’re talking a single building or a larger campus, proper strategy for this key HVAC component requires the right team working at the right times. Both physical and fiscal safety may depend on it.

Commercial kitchen ventilation (CKV) has been a challenge to mechanical engineers for years. Part of the challenge comes from the fact that the mechanical engineer is normally not the “kitchen consultant.
