7. Building Level Testing

7.1. Purpose

Successful performance at this level is the ultimate goal of power failure and recovery testing.  In some situations, this is the only level at which testing will occur.  Generally, the more complex the building or system and the higher the likelihood of damage as the result of a failure, the more desirable it will be to do testing at the system or component level prior to proceeding with a building level test.

The purpose of testing at this level is targeted at verification of the response of the entire building to a loss of and  ensures that the integrated response of the entire building will be satisfactory.

7.2. Special Instructions

Requirements are similar to those sited previously for component level testing.

7.3. Special Equipment Required

Requirements are similar to those sited previously for component level testing.

7.4. Acceptance Criteria

Acceptance criteria at this level generally involve a stable, predictable, and safe response of the entire building to the loss and reapplication of power, including transfers to and from alternative power sources.

7.5. Precautions

Requirements are similar to those sited previously for system  level testing.

7.6. Prerequisites

Power failure and recovery testing at this level is generally one of the last tests performed.  This is because it is necessary for all of the systems and subsystems in the building to be fully operation.  In addition it is highly desirable that the building envelope represents the final configuration and that the building use patterns are approaching what will normally be seen.

7.7. Preparation

Requirements are similar to those sited previously for system  level testing.

 

7.8. Procedure

7.9. Items to Test, Acceptance Criteria, and Method of Test

Testing at this level will focus on the integrated response of all of the components and systems listed in the preceding sections, including the response to recovery from a power failure on an alternative power source.  The item under test is the building as an integrated assembly.  Generally, the method of test is to simulate simultaneous a loss of power to the building and observe the response.

7.10. Return to Normal

Requirements are similar to those sited previously for component level testing.
