Ventilation & Exhaust Engineering

Engineering for fresh-air supply, exhaust and the balance between air entering and leaving a space.

What this covers

Understanding Ventilation & Exhaust Engineering

Ventilation work starts with what the space is used for and what needs to be removed or controlled. Equipment, duct routes and replacement air must be considered together with the rest of the mechanical system.

When engineering may be required

When to involve an engineer

An engineer may be needed for commercial kitchens, enclosed work areas, equipment exhaust or ventilation changes associated with a new use.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Engineering tasks

What the engineer may review

Topics that may be relevant to the review: HVAC, air handler, chiller, condensing unit, ductwork and heat pump.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.
