BLAST (Building Loads Analysis and System Thermodynamics) - FREE

Merged with DOE2 to Become Energy Plus

EnergyPlus merged two major building energy simulation programs: DOE-2 and Building Loads Analysis and System Thermodynamics (BLAST) in 2008. Development of both software tools began in the 1970s, when the U.S. Department of Defense began funding the software that became BLAST and the Department of Energy began funding the DOE-2 program.
