BEDES, the Building Energy Data Exchange Specification, has been created by Lawrence Berkeley National Laboratory (LBNL), with the help of the many stakeholders of the BEDES Technical and Strategic Working Groups, and funded by the U.S. Department of Energy (DOE), to help facilitate the exchange of information on building characteristics and energy use. It is intended to be used in tools and activities that help stakeholders make energy efficiency investment decisions, track building performance, and implement energy efficiency policies and programs.
This spreadsheet represents the BEDES Dictionary Version 1.0 which will be used to support the analysis of the performance of buildings by providing a common set of terms and definitions for building characteristics, efficiency measures, and energy use.
The terms and definitions in this BEDES Dictionary were taken from a variety of sources in order to be as complete as possible as well as being inclusive of the existing implementations that characterize the energy use in buildings.
In order for the standardized terms and definitions of the BEDES Dictionary to be incorporated into different implementations, schemas and import/export formats will need to be developed for specific use cases by the appropriate stakeholders. This will allow "compliance" with BEDES, as shown in the BEDES Compliance tab in this spreadsheet.
The BEDES Community is a diverse group of stakeholders, including software developers, government entities (such as cities and states), energy consultants, and energy providers (such as utilities). A strong BEDES Community will be crucial to the success of BEDES for standardizing data exchange, both from a technical and implementation standpoint.
In Fiscal Year 2015 (FY 2015), LBL and DOE are planning to participate in several pilot programs of BEDES, some in conjunction with the SEED Platform. These pilot programs will help us discover how BEDES can be improved, and based on feedback from these programs, as well as stakeholders in general, we plan to release two updates to the dictionary during the year. We are also planning to develop an interactive website which will contain the BEDES Dictionary in a searchable format. The website will include links to the BEDES Technical and Strategic Working Groups Forums, as well as links to the use case schemas and import/export formats for compliant implementations. We also plan to help individual implementations develop the schemas, field mappings and import/export formats. And lastly, we will work toward the transition of BEDES support to a non-profit organization.
We encourage all stakeholders to participate in this process, and to provide feedback to LBNL as BEDES 1.0 is implemented. We also encourage all stakeholders to become members of the BEDES Technical Working Group Forum and/or the BEDES Strategic Working Group Forum. You can request to become a member, or send general feedback about BEDES, by emailing
