System Audit
A system audit (air flow or water flow measurements) or an existing system survey is a set of measurements used to determine the ventilation rates or hydronic system's performance and recommend steps in improving performance.
Key benefits for having a Systems Audit done:
- When ongoing issues become more complex, a system audit is required to collect information in solving these issues.
- A system audit can also help building owners or mechanical consultants to get a snap shot of the HVAC system's performance.
- For example periodically in healthcare facilities is required to determine the number of air changes. The air changes rates are compared to ASHRAE Standards or CSA Guidelines.
