performance data to assess how systems are currently functioning. This enhances understanding and facilitates effective management and troubleshooting.

Cover all major building systems and associated controls, including the following:

• HVAC . Describe the project’s predominant HVAC system configuration for the plant, AHU(s), and terminal units as applicable. Include information on the type of system(s), equipment capacity ranges and total capacities, high-level summary of equipment efficiencies, and controls contributing to efficiency (such as Energy Recovery Ventilation, Demand Control Ventilation, or variable speed and flow configuration). Describe how the design achieves quality of life for the building occupants.

Further describe non-predominant HVAC system types, the spaces they serve, and any key factors affecting these spaces’ energy efficiency, indoor air quality, or thermal comfort. Provide greater detail for the systems that contribute more strongly to overall energy use, such as systems with high ventilation loads.

In the systems summary, provide detailed information on the ventilation system operation, including a description of the ventilation air delivery mechanism (such as a dedicated outside air system) and a description of minimum required flow rates at design conditions and, if adjusted using demand control ventilation, during periods of low occupancy.

• Service water heating . Provide a brief description of the service water heating for commercial applications with low service water heating loads and a more detailed description of the service water heating equipment types, capacity ranges, efficiency, and distribution type for projects with high service water heating loads, such as residential spaces or hospitals.

• Electrical power . Provide a summary description of the type(s) of interior and exterior lighting, estimated overall lighting power controls to reduce lighting energy use such as occupant sensor controls or daylight dimming controls, and key parameters pertaining to occupant well-being and energy efficiency.

Additionally, provide a summary of electrical submetering at the panels, on-site power generation and/or energy storage, and if applicable, delineate any major power losses in the electrical systems (for example, data centers with losses through the incoming electrical service segment, UPS, and the IT equipment distribution segment).
