| Operation and Maintenance (O&M) Measures |
|
|
|
 |
| Building Envelope |
|
-
Replace worn and/or broken weather-stripping and caulking.
Insulation
- Replace water damaged insulation
|
|
|
| Space Cooling |
|
-
Repair insulation on cooling system pipes.
-
Isolate off-line chillers.
-
Adjust head and suction pressures
Controls
- Adjust controls to stage compressors
- Reset high/low pressure control differential settings
- Install locking thermostat covers
- Calibrate all sensors and gauges
- Reduce/eliminate simultaneous heating/cooling (check with engineer if this strategy applies to particular buildings
- Develop load vs. capacity matrix and match load with equipment capacities
Maintenance
-
Remove scale deposits from shell/tubes on water condensers
|
|
|
| Space Heating |
|
Controls
-
Calibrate all sensors and gauges.
-
Develop load vs. capacity matrix and match load with equipment capacities.
Boiler Issues
-
Tune up boiler by adjusting air-fuel ratio. Isolate off-line boilers.
-
Remove scale deposits, accumulation of sediment and
-
boiler compounds on water side surfaces (especially rear portion of boiler).
Maintenance
- Repair steam traps.
- Repair or replace broken or missing insulation on pipes.

.
|
|
|
| Ventilation/Distribution |
|
Re-wire restrooms' exhaust fans to operate only when lights are on.
Controls
-
Set controls to automatically close all outdoor air intake dampers when equipment is shut off and when building is unoccupied.
-
Adjust economizer for proper operation.
Repair
Maintenance
- Adjust dampers and damper actuators for proper function.
- Adjust dampers to ensure complete closure.
- Re-adjust position indicators to accurately indicate damper positions.
|
|
|
| Domestic Hot Water |
|
- Repair/replace pipe insulation.
- Schedule heater and recirculation pump to operate only during occupancy periods.
|
|
|
| Controls |
|
- Calibrate all sensors (e.g., temperature, pressure, CO2) per manufacturer's recommendations.
- Repair and/or calibrate thermostats.
- Prevent simultaneous heating and cooling within zones and within school building (Check with engineer if appropriate for particular buildings).
- Install locking thermostat covers.
- If BAS/DDC/EMS system exists,
- Set up warm up cycle (close outside air damper during unoccupied period).
- Set up discharge air temperature reset.
- Set up discharge water temperature reset.
- Set up economizer.
- Set up optimum start/stop (close outside air damper during unoccupied period).
Pneumatic
-
Repair excessive leaks in pneumatic controls
|
|
|
| Kitchen Equipment/Systems |
|
