EQUIPMENT RUN-TIME SCHEDULES

Provide the weekly and daily schedules for equipment, such as HVAC, lighting, and process equipment, contributing substantially to overall building energy use. For HVAC equipment, this generally corresponds to the occupancy schedules, extending some time before and after occupied operation. By tracking these schedules in the CFR, facilities managers can ensure that equipment operates only when necessary, in alignment with the occupancy schedules. This reduces operational costs, minimizes wear and tear on equipment, and maintains comfortable indoor conditions. Proactively managing these schedules contributes to improved operational performance and supports sustainability efforts.

• Address the major HVAC and service water heating equipment serving the project and any significant variances in runtime for equipment serving different areas. For projects that do not operate continuously, identify the subset of equipment operating hours when ventilation is supplied to the project or spaces.

• Identify indoor and outdoor lighting schedules and separately summarize lighting addressed by centralized building controls versus lighting addressed with localized controls. If the project has decorative or display lighting with operating hours that differ from the general lighting, differentiate between these lighting schedules in the CFR.

• Summarize equipment runtime for other systems that contribute significantly toward overall building energy use, such as commercial kitchen equipment or other process energy-using systems.

• Briefly summarize HVAC and lighting operation during unoccupied periods, including HVAC load cycling, HVAC start/stop controls that adjust equipment start time to optimize energy efficiency, and lighting overrides for centrally controlled lighting systems.

SETPOINTS FOR HVAC EQUIPMENT

Delineate the temperature and humidity setpoints for HVAC equipment, including any significant differences between HVAC systems, property types, or space types. This helps facilities managers ensure occupant comfort while limiting overheating or overcooling that wastes energy.

LIGHTING LEVELS

Tracking required lighting levels empowers facilities managers to improve energy efficiency and occupant satisfaction by maintaining the controls to achieve these levels. This is particularly effective for lighting with stepped or continuous dimming controls for daylit spaces or new lighting with initial full-load illumination exceeding occupant needs.
