0.2 SUMMARY
A. The project shall be constructed utilizing USGBC LEED NC version 2.2 Guidelines. As
part of the certification process the project shall be commissioned for both EA Pre-
requisite 1_ Fundamental Commissioning and EA Credit 3_ Enhanced Commissioning.
The purpose of commissioning is to verify that the buildings energy related systems are
installed, calibrated and perform according to the owners project requirements, basis ofdesign, and construction documents.
B. The Commissioning Authority (CxA) is TestMarcx and is contracted directly to theOwner. The CxA shall lead the commissioning team, review and oversee the
commissioning process. The process of commissioning as defined here-in for HVAC,
Plumbing and Electrical system installation, start-up, calibration and functional
performance both in detail of testing and in detail of documentation. The director of the
commissioning process is the Commissioning Authority.
C. The contractor shall be responsible to provide all aspects of the process of
commissioning not provided by the CxA under the direction of the CxA as described in
the specification under commissioning responsibilities.
D. Commissioning is a systematic process of ensuring that all building systems perform
interactively according to the design intent, basis of design, construction documents andOwners system operational needs. This is achieved by beginning in the design phase,
documenting design intent/basis of design and continuing through construction,
building acceptance and the warranty period with actual verification of performance.
The commissioning process shall coordinate what have traditionally been separate

PART 3 - EXECUTION
0.11 COMMISSIONING PROCEDURE
A. Sequence of testing: The contractor is responsible to commission all systems listed. The

COMMISIONING GENERAL REQUIREMENTS
01 91 13-16
7/31/2019 8117 SJSU Cx General Requirements
17/30
establish a level of quality. The CxA may or may not utilize sampling techniques on
multi-type non critical systems such as lighting and terminal units to verify the testing.
This does not relieve the contractor of his responsibility to functionally test 100% of the
commissioned systems.
B. Commissioning shall proceed from lower to higher levels of complexity. For each
discrete subsystem or system, testing at the lower level shall be completed prior tostarting the next higher level of tests. In general, the order of testing from lowest to
highest is:
2. Static tests (such as duct leakage and pipe pressure tests).
3. Component functional performance tests (of motors, actuators, sensors, etc.) and
start-up of major equipment.
4. Contractor Testing and Balancing.
5. System functional performance tests(see list of commissioned systems).
6. Intersystem functional performance tests, BAS graphics verification.
A. Re-testing: The Contractor shall repeat, at no additional cost to Owner, the complete
functional test procedure for each test for which acceptable results are not achieved.
Repeat tests until acceptable results are achieved. The CxA shall track commissioning
deficiencies until correction. Within each system, the CxA shall provide one re-
commissioning for any deficiencies. For systems with large quantities of identical
equipment, a statistical re-commissioning strategy shall be applied to retest 20% of the
deficiencies. The tested systems will not be witnessed by the Owner until acceptable
results are achieved, documented, reviewed and accepted. Additional testing beyond a
single failure may be subject to back-charges by the CxA.
B. Correction of deficiencies:
7. Correct functional performance test deficiencies promptly and schedule retest.
8. Corrections during functional performance tests are generally prohibited to avoid
consuming the time of personnel waiting for the test, but not involved in making
the correction. Exceptions will be allowed if the cause of the failure is obvious
and corrective action can be completed in less than five minutes. If corrections
are made under this exception, the failure shall be noted on the functional
performance test data form. A new functional performance test data form,marked retest, shall be initiated after the correction has been made. The entire
functional performance test procedure shall be repeated.
A. Delegated witnesses: Witnesses may be designated by the Owner or A/E to observe the
commissioning process. Witnesses shall provide no labor or materials in the
commissioning process. The only function of the witnesses shall be to observe and
comment on the progress and results of commissioning.

MECHANICALFUNCTIONAL TESTING PROCEDURE (Sample)
System: Chiller - Primary Chilled Water
Test No.: 114c
Title: Staging of Multiple Chillers - Automatic Control (4 or more chillers w/ pump sets)
Equipment Tag:
Testing Accepted: CxA: Date:
Contractor: Date:
Owner: Date:
Comment: Perform this test with at least one chiller already on. Loading of the chillers can be accomplished by openingHW valves at AHUs in the spaces (best method for observing a natural staging)), opening up the isolationvalves on the flat plate HX to false load the chiller (next best but does not cause a flow change). During the
staging tests, most likely there will be some chiller failures and if not, this is an opportune time to cause oneand simultaneously observe chiller failure sequencing. Review the chiller failure test #118a.
Sequence: Chiller Staging Control:1. The number of chillers and MODE of operation requested by the software shall be displayed on the
chiller graphic. These parameters shall be able to be manually adjusted by the operator toautomatically stage on or off chillers.
2. Stage Chiller On: When the Primary Chilled Water Return temperature rises 160F above the chilledwater supply setpoint for 5 continuous minutes and the previously staged on chillers have beenenabled for 20 minutes:a. The next in line LAG cooling tower isolation valves shall open.
b. Upon sensing that the cooling tower isolation valves are open, the next in line LAG chilledwater and condenser water pumps shall energize.
c. At the same time the pump energize command is given, the next in line LAG chiller chilled
water and condenser water motorized isolation valves shall open.d. Upon sensing that all chiller isolation valves are open the pumps are proven on, the next in line
LAG chiller shall be enabled.
Pass Fail Event# Description of Testing Event Expected Results
1 Initial Testing: With at least one chiller on,initiate a chiller staging response bymanipulating staging temperature and
timing setpoints.
This is primarily to confirm timing issues of devicesrelated to the chiller staging. This is best accomplishedone chiller at a time.
1a Observe the cooling tower isolation valveoperation.
The cooling tower valve on the next in line coolingtower opens and the open status is proven.
1b Observe Chilled water pump and chilledwater isolation valve operation.
The chilled water valve and chilled water pump will becommanded to open/start simultaneously. This isintended to prevent an evaporator flow switch trip.Some adjustment of the valve vs. pump timing may berequired. (i.e. the valve may need to be commanded a
few seconds before the pump).1c Observe condenser water pump andcondenser water isolation valve operation.
The condenser water valve and condenser water pumpwill be commanded to open/start simultaneously. Thisis intended to prevent a condenser flow switch trip.Some adjustment of the valve vs. pump timing may berequired. (i.e. the valve may need to be commanded a
few seconds before the pump).
1d Observe the enable of a chiller. The next in line chiller will show a remote start at thechiller LCP.
1e Observe the cooling tower fan operation. After the chiller stage is fully proven, the coolingtower control loops for the newly stage tower will beenabled.
1f Observe the rotation sequencing. Thistesting is specifically identified in test 115
1g Repeat steps 1 through 1f for eachchiller...one at a time for the initial testing
2 For final testing, load the chiller system ina more real life manner such as creatinga cooling load at the AHUs via the HWcoils.
The more air handling systems that are on-line duringthis test, the better the test will perform. Be cautious inthat some swings in space temperatures may occurdepending on how well the AHU controls respond.
2a STAGE ON: Stage up from 1 chiller to 2. Chiller will stage on naturally when the primarychilled water return temperature exceeds the chilledwater supply setpoint by 16 degrees (or as set).
2b STAGE OFF: Stage a chiller back off.
Observe rotation.
Chiller will stage off naturally when the primary
chilled water return temperature is within 9 degrees ofthe chilled water supply setpoint.
2c STAGE ON: Stage from 1 chiller to Stage
