CALGreen Section: 5.410.2.4 Functional performance testing. Functional performance tests shall demonstrate the correct installation and operation of each component, system, and system-to-system interface in accordance with the approved plans and specifications. Functional performance testing reports shall contain information addressing each of the building components tested, the testing methods utilized, and include any readings and adjustments made.
Intent:
Develop and implement the functional performance tests to document, as set forth in the
Commissioning Plan that all components, equipment, systems and system-to-system interfaces were installed as specified, and operate according to the Owner’s Project Requirements, Basis of Design, and plans and specifications.
The following systems to be functionally tested are listed in the Basis of Design (5.410.2.2 of the Code):
1. Heating, Ventilation, Air Conditioning (HVAC) Systems and Controls
2. Indoor Lighting System and Controls
3. Water Heating System
4. Renewable Energy Systems
5. Landscape Irrigation Systems
6. Water Reuse Systems
Existing Law or Regulation:
Title 24 Acceptance Testing requirements call for functional testing of some systems and equipment required to be commissioned by CALGreen. Refer to Title 24 and Nonresidential Compliance Manual ForCalifornia’s 2008 Energy Efficiency Standards.
http://www.energy.ca.gov/title24/2008standards/nonresidential_manual.html
Note: CALGreen Functional Performance Tests are not intended to replace the Title 24
Section 6 Acceptance Tests. Instead, the T24 acceptance tests, which focus on energy efficiency, can be part of the broader scope of testing forms and procedures required for CALGreen compliance.
Review local ordinances for any applicable requirements.
Compliance Method:
Compliance is demonstrated by developing and implementing test procedures for each piece of commissioned equipment and interfaces between equipment and systems according to the
building-specific Commissioning Plan. Tests should include verification of proper operation of all equipment features, each part of the sequence of operation, overrides, lockouts, safeties,
alarms, occupied and unoccupied modes, loss of normal power, exercising a shutdown,
startup, low load through full load (as much as is possible) and back, staging and standby functions, scheduling, energy efficiency strategies and loop tuning.
Elements of acceptable test procedures include:
1. Date and Party — Identification of the date of the test and the party conducting the test.
2. Signature Block — Signature of the designated commissioning lead and the equipment installing contractor attesting that the recorded test results are accurate.
3. Prerequisites — Any conditions or related equipment checkout or testing that needs to be completed before conducting this test.
4. Precautions — Identification of the risks involved to the test team members and the equipment and how to mitigate them.
5. Instrumentation — Listing of the instrumentation and tools necessary to complete the test.
6. Reference – In each procedure item, identify the source for what is being confirmed (e.g., sequence of operation ID, operating feature, specification requirement, etc.).
7. Test Instructions — Step-by-step instructions of how to complete the test, including functions to test and the conditions under which the tests should performed.
8. Acceptance Criteria — Measurable pass / fail criteria for each step of the test, as applicable.
9. Results — Expected system response and space to document the actual response, readings, results and adjustments.
10. Return to Normal — Instructions that all systems and equipment are to be returned to their
as-found state at the conclusion of the tests.
11. Deficiencies — A list of deficiencies and how they were mitigated.
See (Part 4) for forms and templates.
Enforcement:
At their discretion, the building official confirms demonstrated compliance during Onsite
Enforcement by:
a)Receipt of a copy of completed and signed Functional Performance Tests and corrected deficiencies, or
b)Receipt of a form signed by the owner, owner representative or commissioning coordinator attesting that the Functional Performance Tests have been completed and any deficiencies corrected.
See (Part 4) for forms and templates.
CALGreen Section: 5.713.10.4 Testing and adjusting. Testing and adjusting of new systems installed to serve an addition or alteration subject to Section 5.701.1 shall be required.
[Balance of subsections are unchanged from those in Division 5.4]
Intent:
These provisions for means of achieving quality control for building systems are being proposed additions and alterations where a new system is installed or an existing one upgraded to serve a
new or renovated space. This promotes energy and water savings as systems are installed, tested, and adjusted for maximum efficiency when the project is turned over to the owner.
Operation and maintenance information is to be provided to the owner to assist with continued
efficiency beyond certificate of occupancy.
Compliance and Enforcement: See § 5.410.4 and subsections of this guide
