Ventilation and exhaust
Fresh air and exhaust that match how each room is used
Break rooms, restrooms, exam rooms and conference rooms each need their own fresh air and exhaust. We size it to code and test it before you move in.
A suite that feels stuffy is often short on outside air, or the exhaust is pulling it the wrong way. We measure both before and after.
Typical scope
Outside air amounts by room type
Restroom and break-room exhaust
Heat or energy recovery where the code or the building calls for it
Dampers and fire-rated penetrations coordinated with your contractor
A written test of airflow at turnover
What drives the scope
What changes a ventilation scope
The use of the room decides more than its size.
Room use
Exam rooms, kitchens and restrooms each have their own requirement.
Occupancy
More people in the room means more outside air.
Where air can enter and leave
Roof, wall or shaft, and what is near the intake.
Recovery
Energy recovery adds equipment, and may be required by the energy code.
Fire and smoke
Rated walls and dampers need coordination with your contractor.
Controls
Schedules and sensors that shut off outside air when the suite is empty.
Questions about ventilation
Why does the suite feel stuffy after the build-out?
New walls can leave a room with no supply or no return. A balance report shows which rooms are short, and the fix is usually a duct or damper change.
Do you add exhaust for a new break room?
Yes, with the duct to the outside and the makeup air it needs. It is on the permit with the rest of the mechanical work.
Can you measure the air in a suite we already occupy?
We can measure airflow and tell you what we find. We don't test or promise air quality outcomes.
