Commissioning Plan
The commissioning plan must contain: Overview & goals Project information Systems to be commissioned Team’s roles & protocol Describe Deliverables List Key Milestones and schedule.
What Systems does LEED require Commission? Systems and Assemblies having to do with
operational efficiencies: HVAC Systems Building Automation Lighting Controls Domestic Heating Renewable Energy

1 Panel HCR2 8/9/2004 FIVThe electrical working clearance for Panel HCR2 is not per NEC 110. Panel LCR2 blocks the right portion of the panel width within the 42" reqmt.
CEC
2 Panel LCR2 8/9/2004 FIV
The electrical working clearance for Panel LCR2 is not per NEC 110. The conduits at the floor in front of the panel, penetrate the floor in front of the plane of the panel can.
CEC
3 Panel HN3 8/9/2004 FIV
The electrical working clearance for Panel HN3 may not be per NEC 110. The transformer and flexible conduits @ the floor must be 42" from the panel (exposed live parts).
CEC
4 Panel LCR5 8/9/2004 FIVThe electrical working clearance for Panel LCR5 is not per NEC 110. The adjacent panel can blocks the right portion of the panel width within the 36" reqmt.
CEC
5 AHU 1 8/9/2004 FIVThe chilled water coil pull is blocked by the header at the coil.
B&KFlanged connections have been provided in the piping above the coil for piping removal for coil pull.

7 RF 5A and B 8/9/2004 FIV
The FSDs at the floor entering the return (see sheet M406) are not accessible without dismantling a section of the fabricated return plenum. An access door is not shown to be installed.
B&KPCA
Removable access panels have been provided in the return plenum for access to FSDs.

Issues & Lessons Learned
General Commissioning is Part of the Design Team Contractors understand the commissioning TEAM’s
Role Energy Efficient Systems
Controls Become Complex and increase Risks Technology is beyond Contractor Experience Coordination of interposing systems is critical
Control Systems Integration is coordinated Schematic diagrams, Sequence of control and point
lists are necessary Details of BMS get input from owner
Owner Training Video tape or not? Meeting with Staff to discuss needs Detailed Description in Spec of O&M needs. Systems Manual training
