Dennis Yarmouth Intermediate Middle School January 19, 2021 Dennis Yarmouth Regional School District 100% Construction Documents Perkins Eastman DPC, project #71011 01 9113 General Commissioning Requirements 2 of 2 1.5 DESCRIPTION OF WORK A. The objective of commissioning is to provide documented confirmation that a facility fulfills the functional and performance requirements of the building owner, occupants, and operators. To reach this goal, it is necessary for the commissioning process to establish and review the owner’s criteria for system function, performance, and maintainability (Design Intent); and to also verify and document compliance with these criteria at start- up, and the initial period of operation. In addition, complete operation and maintenance (O&M) manuals, as well as training on system operation, should be provided to the building operators to ensure the building continues to operate as intended. B. The Commissioning Agent (CA) shall be involved throughout the warranty phase. During construction, the CA develops and coordinates the execution of a testing plan, which includes observing and documenting all systems’ performance to ensure that the systems are functioning in accordance with the owner’s Design Intent (DI) requirements and the contract documents. The CA is not responsible for design or general construction scheduling, cost estimating, or construction management, but may assist with problem- solving or resolving non-conformance issues or deficiencies. The installing Contractors, TAB Sub and ATC Sub shall be required to provide support of the commissioning under their base Contracts. C. The following is a summary of services provided for commissioning: 1. Develop commissioning plan 2. Develop pre-functional and functional test procedures 3. On-site reviews to confirm that systems are ready for commissioning 4. Witness piping and ductwork tests 5. Witness system flushing 6. Review system start-up reports 7. Maintain master deficiency and resolution log 8. Perform prefunctional and functional testing 9. Ensure O&M and commissioning documentation requirements are complete. 10. Coordinate Owner staff training 11. Final report and presentation to Owner 12. Follow up visits after occupancy to review building operations D. Commissioning does not reduce responsibility of installing contractors to provide a finished and fully functioning product. E. This section shall in no way diminish the responsibility of the Divisions 07, 08 21, 22, 23, 26, 27, 28 Contractors, Sub-contractors and Suppliers in performing all aspects of work and testing as outlined in the Contract Documents. Any requirements outlined in this section are in addition to requirements outlined in those divisions. 1.6 ABBREVIATIONS A. The following are common abbreviations used in the Specifications.

Functional Testing Record Air Handling Units Test # Mode ID Test Procedure Expected Response Pass Y/N Note 1 Unoccupied Mode Using BMS put unit into unoccupied mode. Using the trend log features ensure the following occurs OA temp is above 40ºF. - Verify Outside Air and Exhaust Dampers are Closed and return air damper is open, HW/CHW coil valves are closed OA temp is below 40ºF – The HW heating coil valve is 25% open subject to safeties. Unit in unoccupied with a call for heat – If Average temperature drops 2 degrees below the unoccupied heating setpoint of 60ºF (adj) OA damper shall remain closed. Subject to safeties, supply fan shall cycle and 3-way valve shall open based on call for heat from space sensor. Once space temp is 1ºF above unoccupied setpoint, the supply fan shuts down. Ensure areas with perimeter radiation use radiant heat as 1st stage if applicable 2 Morning Warm-up Set up trends for morning warm up status, heating control valve temperature, discharge air temperature and supply fan status Check trending to verify that the warm up cycle is occurring prior to the occupied mode enable. OA dampers remain closed, SF starts, and HW valve opens 100%. The supply fan VFD shall modulate to maintain static pressure setpoint. 3 Occupied, Fan On Return unit to occupied mode using BMS. Outside, return and relief damper opens to minimum position, supply fan and return fan start (once OA damper is proven open), RA damper modulates inverse of OA damper. 4 Supply Fan and Return Fan Control Using BMS set unit to occupied mode Supply fan starts and runs continuously during occupied times. Return fan VFD shall track the supply fan by an adjustable offset as determined by the balancer. Manually fail the supply fan and return fan Verify an alarm is generated at the BMS 5 Economizer Control Simulate a situation, using the BMS controls where the unit is looking for cooling and the OA enthalpy is less than 22 btu/lb. HW valve closed, OA damper modulates to 100% open.

Cool air shall be delivered. 7 Hot Water Heating Coil In occupied mode, with fan running, raise the space temperature setpoint Verify the hot water coil valve modulates to satisfy the heating requirement. (Ensure the system resets Supply air temperature to maintain space temp (adj.)) 8 Smoke Control Simulate a smoke condition Verify the duct smoke detectors will send a signal to stop the fans and close the OA dampers 9 Freeze Condition Manually simulate a freeze condition at the low limit duct thermostat Verify the supply fan stops, OA dampers close, heating coil valve opens (when temp falls below 40ºF) and an alarm is sent to the BMS Manually reset the alarm The alarm shall be cleared and the units shall be capable of restarting 10 Filter Switch Simulate a dirty filter condition Ensure that the BMS reports an alarm 11 Demand Control Ventilation (C02 Override) Simulate a CO2 level beyond the adjustable setpoint The outside air damper shall be allowed to modulate past minimum position until the CO2 concentration has fallen below setpoint
