L20 ENERGY & PROCESS ASSESSMENT PROTOCOL
7.13 Photo and X-ray Processing
7.13.1 Install temperature control valve to reduce fl ow when not developing.
7.13.2 Reduce fl ow to manufacturer’s specifi cations for actual operating conditions.
7.13.3 Install solenoid valve to shut off rinse and cooling fl ows when product is not being de-
veloped.
7.14 Process Control
7.14.1 Install, replace, or alter energy management control systems (EMCSs).
7.14.2 Install demand-limiting control system.
7.14.3 Install duty-cycling control system.
7.14.4 Install economizer cooling control system.
7.14.5 Install hot/chilled water supply temperature reset control systems.
7.14.6 Install supply air temperature reset control system.
7.14.7 Install temperature setup/setback control system.
7.14.8 Install time-of-day control system.
7.14.9 Install ventilation-purging control system.
7.14.10 Install single-building controllers (DDC).
7.14.11 On/off controls (electronic time clocks).
7.14.12 Install temperature control valve to reduce fl ow when not developing.
7.14.13 Reduce fl ow to manufacturer’s specifi cations for actual operating conditions.
7.14.14 Install solenoid valve to shut off rinse and cooling fl ows when product is not being de-
veloped.
8 Regular Maintenance Plan
8.1 General
8.1.1 Inspect to ensure dampers are sealed tightly.
8.1.2 Clean coil surfaces.
8.1.3 Ensure doors and windows have tight seals.
8.1.4 Check fans for lint, dirt, and other causes of reduced fl ow.
8.1.5 Schedule HVAC tuneups (the typical energy savings generated by tuneup is 10%).
8.1.6 Check and calibrate thermostat regularly.
8.1.7 Replace air fi lters regularly.
8.1.8 Adjust fan speed and belt drives.
8.1.9 Check valves, dampers, linkages, and motors.
8.1.10 Check/maintain steam traps, vacuum systems, and vents in one-pipe steam systems.
8.1.11 Repair, calibrate, or replace controls.
8.2 Cooling System Maintenance
8.2.1 Clean the surfaces on the coiling coils, heat exchangers, evaporators, and condensing
units regularly so that they are clear of obstructions.
