Building/Control System Verification

Building Annual Verification

In sensitive environments such as hospitals, laboratories, and clean facilities, maintaining proper pressure relationships is essential for safety, compliance, and performance. At Provision Environmental Systems & Testing, we provide annual verification testing to ensure your building systems continue to operate exactly as designed.

Why Annual Verification is Critical

Over time, system performance can drift due to equipment wear, control changes, or facility modifications. Annual testing provides peace of mind by verifying that:

Air Changes per Room – Each space maintains the required positive or negative air changes.
Pressure Relationships – Critical pressurization between adjacent rooms is confirmed.
Compliance Standards – Facilities remain aligned with healthcare, laboratory, and NBC requirements.
Comfort & Safety – Patients, staff, and occupants are protected with stable, healthy environments.

Our Verification Process

Measure & Document – We establish the actual total air changes per room and verify pressurization relationships.
Identify Deficiencies – If requirements are not met, our specialists perform a thorough investigation to determine root causes.
Implement Solutions – Corrective measures are provided and adjustments made to achieve compliance.
Retest & Certify – A complete HVAC Testing, Adjusting, and Balancing (TAB) report is submitted for records and compliance review.

At Provision, our goal is simple: to ensure your facility maintains optimal performance year after year—providing a safe, efficient, and compliant environment for those who rely on it most.

Control System Verification

A building’s control system is the brain of the HVAC operation—responsible for ensuring comfort, efficiency, and reliability across every space. At Provision Environmental Systems & Testing, we perform Control System Verification as part of the Total System Balance (TSB) process, confirming that your systems operate exactly as the design team intended.

Why Control Verification is Essential

Even the most advanced mechanical systems cannot function as designed if controls are miscalibrated, misprogrammed, or not fully integrated. Our verification process ensures:

Design Compliance – Systems follow the specified sequence of operations across all modes.
Accurate Inputs & Outputs – Controllers and sensors are properly calibrated and functioning as intended.
Reliable Performance – HVAC systems operate seamlessly in real-world conditions.
Collaborative Assurance – Coordination with control contractors ensures a shared understanding of performance expectations.

Our Verification Process

Contractor Coordination – We work directly with the control contractor to align expectations and performance goals.
Calibration & Function Testing – Every sensor, controller, and device is verified for accuracy and responsiveness.
Sequence Validation – Each sequence of operation is tested against design documents for full compliance.
Mode Testing – Systems are evaluated under all modes of operation (heating, cooling, economizer, emergency, etc.) to ensure reliability.

At Provision, our role is to provide owners, engineers, and contractors with confidence that their control systems deliver precision, efficiency, and performance—exactly as designed.
