Component models

A detailed specification of available component data models and their application.

Overview¶

Component data models are utilized to create virtual twins of building equipment. They are templates representing the correlation between data points and metadata of building equipment. To create such a virtual twin, a component data model gets added to a specific project, and data points and metadata get mapped to its pins (placeholders for data points) and attributes (placeholders for metadata).

This page offers specifications on the available component data models and available analytics functions for each component.

Alphanumeric IDs¶

Alphanumeric IDs are used to access component pins and attributes via the API. Each ID is unique and contains information about the pin/attribute and corresponding component. See component data models for more information on alphanumeric IDs of all pins, components, and attributes.

Application notes¶

Hints for a smooth application of component data models and their mapping.

• 1-to-n mapping: One datapoint can be mapped to several instantiated components to allow data models of different granularity.
• Unit sensitivity: To this state, our algorithms are unit sensitive. Every pin and attribute is specified with a unit. Mind the specifications.

• Incomplete mapping: Pins and attributes, are placeholders which might or might not be mapped to data. Algorithms will work on incomplete mapped components, they require mapping for specific placeholders though. Check the algorithm documentation for the required mappings.
