SuperHeat was building-related software developed by Greentram Software. The .h5b format was used by SuperHeat version 5 for its building files.
Greentram Software's SuperHeat product was acquired by Elmhurst Energy Systems. SuperHeat is now an obsolete product, and the format is no longer actively supported by its developer.
Open an .h5b file with SuperHeat 5, if that software is available. The file may not open correctly in current software because SuperHeat is obsolete and is no longer supported by its developer.
If SuperHeat 5 can open the file, use any save or export function provided by the software to create a file in a supported format.
If the original software cannot open the file, conversion may not be possible without access to a compatible version of SuperHeat.
