Building Equipment

Find comprehensive guidance on the plants, systems, and components that drive energy consumption in buildings.

Plants

Centralized equipment that works together to maintain occupant comfort and provide essential functions in a facility such as air, water, and electricity distribution. Plants comprise various systems and components that serve different functions.

Systems

Interconnected equipment within a facility that support the operation of a plant. Systems fulfill essential functions such as supplying conditioned air, electricity, and hot and cold water, ensuring the building operates efficiently and meets occupant needs.

Components

Individual equipment that constitutes a system and serves as the primary source of energy-consumption. Explore measurement strategies, calculators, equipment lists, and step-by-step setup guides for each component.

help How do I assess the energy consumption or performance of building equipment?
  • For guidance on quantifying the energy use and assessing the performance of plants, systems, and components, see Measurement and Analysis.
  • For guidance on assessing and diagnosing the operation of major systems with or without a BAS, using data loggers and sensors, see Building Re-tuning.
