Definition
  Integrate- join two or more objects or make
   something part of a larger whole, or be made part of
   a larger whole.
  For commissioning an integrated system test can be
   defined as: a test that brings previously functionally
   tested systems together and simultaneously will test
   the designed control sequence for all associated
   systems as a whole in various modes.

Examples of Integrated System Test
  I have included 3 examples of types of integrated
     system test.
       Stair pressurization system which could be in most
        buildings
       Hospital considerations that could work for a
        multitude of systems
       Laboratory and/or vivarium considerations that
        become more complex

Examples of Integrated System Test
  This discussion is for only HVAC systems but the
     same type of testing should be considered for life
     safety, security, lighting, plumbing, elevators, and
     any kind of special process systems.

Examples of Integrated System Test
Stairwell Pressurization
  Emergency power system with stair well
   pressurization system.
  In buildings that have floors 75 feet above grade a
   stair pressurization is required. The system will be
   tested under normal power when originally tested.
   When the building looses power and the power is
   transferred to the emergency generator the stair
   pressurization system will be retested, which is an
   integration of the emergency power system with the
   stair pressurization system.

Examples of Integrated System Test
Stairwell Pressurizati
        This test will determine the stairwell pressurization
         fans start after emergency power has been
         established and they are operating with the correct
         rotation.
        This test will also establish the dampers, alarms and
         smoke detectors are operational under emergency
         power.
        The last part of this test will be to verify everything is
         operational after returning to normal power.

             the control system has UPS power the control

                and how long it takes to establish all room pressures
                 Review the transfer switch time and which
                  systems are assigned to each transfer switch
                 Be careful with rooms that are to be positive, when
                  the sequence requires the exhaust system to be
                  operational before the supply systems are allowed
                  to start
                 On large manifold systems (both supply and
                  exhaust) trending may be required on all AHUs,

        Smoke Control Systems in Labs and Vivariums are
         usually passive, if an AHU goes down because of an
         internal smoke detector the exhaust will remain
         operational but this test should consider the negative
         pressures created in the building

               shown on the smoke control matrix
