Call for Members: Building Data Exchange (BDE) Committee

The industry is in the process of making a steady shift towards connected databases and web technologies for the design, analysis, and operation of built environments. Consequently, the end-user must work with a multitude of unrelated data dictionaries, schemas, and file formats to represent building information for simulation. Although some efforts have been made in the recent past to standardize data models, most practitioners (and programmers), developers, vendors, manufacturers, and performance testing organizations have their own data structures resulting in a high degree of market fragmentation. This fragmentation is detrimental to overall productivity because tools and workflows become incompatible, thus resulting in duplication of effort and inefficient use of project funding.

In the larger interest of the industry and to truly bridge the gap between owners, architects, engineers, modelers, software vendors, Authorities Having Jurisdiction (AHJ), rating agencies, and other related stakeholders, it is recommended that a consensus-based engine-neutral data dictionary and schema be developed to enable building data exchange. 

Identifying current barriers to data exchange, and if necessary, facilitating the development of standard data models will help overcome some of the key barriers to greater adoption of building performance modeling outlined in USDOE BTO’s Emerging Technologies Draft Research and Development document, namely – improving value proposition, increasing accuracy, making time available to develop core modeling capabilities, and facilitating end-to-end workflow automation. 

Therefore, the IBPSA-USA Building Data Exchange (BDE) Committee has been set up to convene the many stakeholders to help alleviate pain-points in everyday data exchange for building performance modeling. 

In order to provide balanced representation and to prevent a single Interest Category from dominating committee activities the following groups have been identified for stakeholder representation:

  • Building Performance Simulation (BPS) Software Developer – individuals that represent the interests of a BPS software program

  • Schema Developer – individuals that represent a specific data schema used for building data exchange

  • Government/AHJ/Rating Authority – individuals that represent an organization that uses the output from BPS software for compliance and certification purposes

  • BIM Software – individuals that represent the interests of a BIM software program

  • Practitioner – individuals that use BIM and BPS software for building design, analysis, and compliance 

  • Data Vendor – individuals that represent the production of data for BPS

  • Standards – individuals that represent other standards that cover data dictionaries, data schemas, and/or data formats

The following table provides a breakdown of the number of voting members available to each Interest Category to ensure balanced representation:
