Dear All, Do stand-by electricity generators need to be commissioned as part of this prerequisite? Note that these aren't modeled in the Energy Model of EAprerequisite2 since they are not the principal source of electricity. Thanks!

Only systems that are working or would work under NORMAL OPERATION are required to be commissioned. Though if any equipment (HVAC or other-wise) is required to operate under emergency power it should be under the functional testing as so (i.e. stairwell pressurization fans, smoke evacuation fans, etc.)

Just to put a finer point on this, if there is a system that ONLY runs during an emergency situation, then LEED would not require it to be testing. Frankly these systems must be commissioned, normally as a requirement of the AHJ, and we always tell our clients this is the one system that you do not drop out of a scope of work! If a system or unit is required to have a mode of operation during emergency, then that mode must be tested as part of the FPT.
