BDA 3.1 Download

Welcome to the download site for the 3.1 version of the Building Design Advisor (BDA) software!  To get familiar with the BDA software quickly we recommend  that you go through the  mini tutorial that is available on this site, as well as the tutorial in the BDA on-line help.  We also recommend that you review the list of known problems and review the BDA Manual.

Before installing the BDA 3.1 software, you may wish to uninstall previous  versions of the BDA software, using the "Install/Remove Programs" application in the "Control Panel" folder, which can be accessed through the "Settings" menu item of the "Start" menu at the Taskbar.  (However, this is not necessary. You can simultaneously use different versions of BDA.) After the "uninstall" process is complete, please delete the BDA directory with all its contents. You may choose to keep the project directories, however, the old projects may not work with newer versions of BDA. In future versions of BDA, we are looking into providing backward-compatibility with older versions of BDA.

The BDA software comes with TMY2 weather files for several US cities.  You can get additional TMY2 weather files from here.  Please read the BDA Manual for instructions on importing them into the BDA environment. You can also get weather files from other sources. These files, however, may need to be converted into TMY2 format before they can be used. A description of the TMY2 format is given here.

The minimum and recommended system requirements to run the BDA software are as follows:

Minimum / Recommended:

  • Pentium 75 / 200 or better.
  • Windows 95, 98, NT  4.0, 2000.
