Brick Schema

General

Brick is an open-source method to describe physical, logical and virtual things in a building and their relationships with one another.

Things that can be described by Brick schema include:

• Locations (e.g. building, level, room, zone, space)
• Equipment (e.g. chiller, pump, fan)
• Points (e.g. air temperature, water flow rate)

Relationships that can be described by Brick schema include:

• partOf (e.g. a room is part of a particular level)
• controls
• feeds
• serves
• locatedIn (e.g. a chiller is located in a particular room)

Currently, Senfi supports brick schema v1.2.0. Only Brick equipment and brick points are supported within Senfi. Brick locations support will be added later.

Brick Schema

Brick schema uses the Resource Description Framework (RDF) and Web Ontology Language (OWL) to describe locations, equipment and points in a building. It includes a dictionary of common location, equipment and point classes (types), as well as relationship types which are used as descriptors of assets.

Examples include:

• Location classes: brick:Building, brick:Level, brick:HVAC_Zone, brick:Electrical_Room
• Equipment classes: brick:AHU, brick:Damper, brick:Variable_Air_Volume_Box, brick:Thermostat
• Point classes: brick:Start_Stop_Command, brick:Motor_Speed_Sensor, brick:Effective_Air_Temperature_Setpoint
• Relationships: brick:hasPart, brick:controls, brick:feeds
