Extracted Content

• Building automation system and/or energy information system . If the project has a building automation system (BAS) with or without fault detection diagnostics and/or an energy information system (EIS), describe the system’s key functions.

  • Process equipment including process heating and cooling . Describe any process equipment contributing significantly to project energy use, including controls and key operating parameters.

Current Sequence of Operations for the Building

Provide the current sequence of operations detailing how the building systems interact to ensure seamless integration and optimal performance.

PREVENTATIVE MAINTENANCE PLAN

A key element of the O+M plan is a preventive maintenance plan for mechanical, electrical, and envelope systems and equipment within the project. This proactive approach identifies and addresses inefficiencies or potential failures through regular checks and routine maintenance, ultimately improving operational efficiency, enhancing indoor environment quality, and prolonging the lifespan of building systems. Equipment downtime, controllability, and thermal comfort may improve as a result of improvements made during preventive maintenance, enhancing the occupant’s experience. [17]

The plan must provide detail regarding the tasks associated with each activity and specified frequencies for each task. Alternatively, the plan may reference where this detail is provided, such as a preventative maintenance tracker in the BAS system:

• Include daily, weekly, monthly, quarterly, and annual tasks, based on manufacturers’ specifications, vendor requirements, industry knowledge, or an automated work order system.

• Address commonly overlooked systems like tenant lighting, domestic hot water, and building automation systems.

• Describe building systems that are maintained by a third party and the current status of the maintenance contracts.
