What is the purpose of ASHRAE Guideline 1.1?

• A. To describe the commissioning process used for HVAC&R systems
• B. To describe the technical requirements for the application of the commissioning process described in Guideline 0 that will verify that the HVAC&R systems achieve the Owner's Project Requirements.
• C. To describe project budgets and timelines
• D. To provide safety guidelines for construction crews

Answer: (B)

Guideline 1.1 sets out the technical requirements for applying the commissioning process to HVAC&R projects so that the Owner’s Project Requirements are actually verified. It takes the general commissioning approach described in Guideline 0 and turns it into concrete criteria: what tests and verifications to perform, what data to collect, how results are documented, who is responsible, and what acceptance criteria must be met. This ensures the system performance is measured against the owner’s goals for comfort, energy use, reliability, and other requirements, making the commissioning effort objective and auditable rather than a series of informal checks.
