Welcome to the home page for the Building Design Advisor (BDA) project!  The BDA is a Windows computer program that addresses the needs of building decision-makers from the initial, schematic phases of building design through the detailed specification of building components and systems. The BDA is built around an object-oriented representation of the building and its context, which is mapped onto the corresponding representations of multiple tools and databases. It then acts as a data manager and process controller, automatically preparing input to simulation tools and integrating their output in ways that support multi-criterion decision making.

The BDA software is developed by the Building Technologies Department of the Environmental Energy Technologies Division at Ernest Orlando Lawrence Berkeley National Laboratory.

The project is funded, in part, by the California Institute for Energy Efficiency (CIEE), a research unit of the University of California. Publication of research results does not imply CIEE endorsement of or agreement with these findings, nor that of any CIEE sponsor. This work was also supported by the Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Building Technology, State and Community Programs, Office of Buildings Systems of the U.S. Department of Energy under Contract No. DE-AC03-76SF00098.
