CCP Owner Training, O&M Manuals & Warranty Period Cx 3

Question 1

The primary purpose of seasonal or deferred testing during the commissioning warranty period is to:

Accepted Answer

Verify system performance under operating conditions not present during initial acceptance testing

Answer

Seasonal testing captures performance data under conditions (peak heating, peak cooling, extreme humidity) that could not be evaluated when the building was initially commissioned in a different season.

Question 2

Per ASHRAE Guideline 0, who is typically responsible for scheduling and coordinating seasonal testing during the warranty period?

Accepted Answer

Commissioning Authority (CxA)

Answer

The CxA retains responsibility for commissioning activities through final completion, including scheduling seasonal tests to coincide with the correct operational conditions.

Question 3

A '10-month warranty review' in commissioning practice refers to:

Accepted Answer

A site visit and systems review conducted before the typical one-year contractor warranty expires

Answer

A 10-month review allows the CxA and owner to identify and document warranty-eligible deficiencies while the contractor warranty is still active, preserving the owner's right to remedy at no cost.

Question 4

Issues and deficiencies discovered during warranty period commissioning activities should be formally tracked in the:

Accepted Answer

Issues Log (or Deficiency Log) maintained by the CxA

Answer

The CxA's Issues Log is the central tracking tool for all commissioning deficiencies throughout the project lifecycle, including the warranty period, ensuring accountability and resolution.

Question 5

Which of the following is the most common example of a system requiring seasonal deferred testing in a heating-dominated climate?

Accepted Answer

Chiller and cooling coil performance at peak summer design conditions

Answer

In a heating-dominated climate, buildings are often commissioned in winter, so chiller and cooling systems cannot be fully load-tested until summer conditions arrive, requiring deferred seasonal testing.
