SEASONAL AND TIME=BASED ADJUSTMENTS

The CFR must also include seasonal and time-based adjustments to operational settings. For example, in the summer, a building may adjust its HVAC settings to maintain a cooler indoor temperature during peak occupancy hours while allowing the temperature to rise slightly during unoccupied periods. This aligns operational settings with seasonal and time-based changes and optimizes energy use while creating a more comfortable indoor environment for occupants.

• Required temperature setpoints and, if applicable, humidity setpoints

• Setpoints for lighting levels

If the project participates in a demand response program or has automated demand side management consistent with EAc6: Peak Load Management, Option 1, list the adjusted setpoints, lighting levels, and enabled equipment associated with a demand response event in the Current Facilities Requirements.

OPTIONAL APPENDIX: BUILDING PLANS

To maximize utilization of the CFR for its intended purpose, project teams can append available building drawings for mechanical/electrical/plumbing systems to the CFR. However, this is not required for prerequisite compliance.

O+M Plan

The operations and maintenance (O+M) plan outlines major system operating parameters and limits, maintenance procedures, schedules, and documentation methods that are necessary to demonstrate proper operation and maintenance of the project’s HVAC, service water heating, electrical, and process energy systems.

Establishing preventive maintenance procedures and frequency for the building systems is crucial for ensuring efficient operation. For example, monthly air filter inspections and quarterly thermostat calibrations help prevent system failures, extend equipment lifespan, and promote overall reliability and energy efficiency.

The O+M Plan includes the following elements:

SYSTEMS NARRATIVE

Provide an overview of the project’s mechanical and electrical systems and equipment, summarize the types of systems, provide an overview of controls, and address key system parameters. Information may be collected through auditing, direct workers’ feedback, and
