Each release of the schema includes several supporting documents, the Schema, a Data Dictionary, List of Measures. More information regarding each of the supporting documents is described below and the various versions of schemas are found here.


The BuildingSync schema can be used to create and validate XML files. There have been multiple releases of the schema and they can be found here.

Data Dictionary

The data field “dictionary” includes field names, definitions, units, and other attributes for the enumerated fields. The data dictionary is aligned with BEDES, but includes only the subset of data fields that are relevant for energy audits. This page can be referenced to help standardize the terminology used in energy audits, but it does not provide a structure that allows data to be exchanged across different applications.

List of Measures

The list of measures defined in the BuildingSync Schema contain a TechnologyCategory and a list of valid enumerations.

Other Supporting Documents

There are several supporting documents that are independent of the version of the schema. The supporting documents include Example Files, a Geometry Reference Sheet, and an Implementation Guide. More information can be found below.

Example Files

These example files aid in applying the schema to a particular energy auditing software. This collection is not exhaustive, but should still be helpful.

Geometry Reference Sheet

The BuildingSync Geometry Reference Sheet illustrates how most of the simplified geometric terms (shapes, side names, vertices, orientations) are defined in the context of BuildingSync.

Implementation Guide

The Implementation Guide is a comprehensive guide illustrating the process needed to adopt the BuildingSync schema. The Guide also provides context for BuildingSync and discusses how it has been developed in close coordination with the energy auditing industry.
