Brick Distribution


The Brick ontology is distributed as a set of Turtle files. Turtle is a compact textual format that is understood by most Semantic Web tools.

Reference Brick Models


These five models are representative examples of how Brick can be used to model real buildings. For an in-depth discussion of the creation and evaluation of these Brick models, please refer to the BuildSys 2016 and Applied Energy 2018 papers.
