Medical, dental and surgical clinics, endoscopy and procedure rooms, sterilization/reprocessing areas and compounding pharmacies must be able to show how their ventilation actually performs: supply and exhaust airflow in every room, air changes per hour (ACH) and the pressure relationship between rooms (positive or negative). GreenTech Air Balancing measures each room on site, calculates ACH from the measured supply airflow and the room volume, observes pressure relationships and documents every deficiency, with reference to CSA Z317.2 healthcare HVAC principles and the design intent of the project engineer.
Typical situations: a new clinic fit-out or tenant improvement, a renovation or HVAC modification, preparation for an Out-of-Hospital Premises (OHP) inspection in Ontario, a landlord or engineer requesting verification, or comfort and odour complaints in treatment rooms. Most clinics are measured in a single site visit; the report follows shortly after. Final design and code compliance remains the responsibility of the design professional, owner and/or regulatory authority — our role is to provide accurate, independent field measurements and clear documentation.
Send us the floor plan and the mechanical drawings or the room list and we will prepare a quotation for the ventilation verification, usually within one business day.

We begin with a detailed review of the HVAC systems to understand design intent, current operating conditions, and performance gaps. Our team evaluates airflow, waterflow, static pressure, and control sequences to establish an accurate baseline before any adjustments are made.
Using industry-standard TAB instruments, we perform precise field measurements across the entire system — diffusers, grilles, VAV boxes, terminal units, hydronic loops, and mechanical equipment. Each measurement follows recognized balancing procedures to ensure repeatable and reliable results.
Once optimal performance is achieved, we compile a comprehensive report including measured data, compliance verification, system observations, and corrective recommendations. Our documentation is structured for engineers, consultants, and facility managers to support long-term building efficiency.
