Software

The Windows and Daylighting Group at Lawrence Berkeley National Laboratory (LBNL) has developed a variety of software tools for analyzing energy performance of windows. Many of these are available to the public free of charge

Subpages to this page describe lesser known programs and program components and macros that relate most directly to optical properties of windows. These are not all officially supported and distributed but providers of data to our databases and users of our main programs may find them useful.
