Factsheet: Data-Driven Smart Buildings
Survey of metadata schemas for data-driven smart buildings
Author(s): Gabe Fierro and Pieter Pauwels
A survey of metadata schemas for data-driven buildings is presented. The aim of this document is to provide insight and clarity into the overall structure, as well as trade-offs and arguments behind each of the major metadata schemas available for data-driven smart buildings. This includes context relating to how those metadata schemas are applied in practice.
Annotating sensor, meter, IoT and other building device data, so that it can be re-used as effectively and meaningfully as possible (regardless of the building typology, location or fabric), is a task best achieved by a common/standardised metadata schema. Creating portable applications that use metadata, to mask the inherent complexities of each building, allows the proliferation of value-adding applications and services.
The intended audience of this paper includes building owners, commissioning agents, system integrators and software developers, who are in a decision-making position for choosing or requiring a metadata standard for enabling analytics.
