The EINSTEIN Expert-System Software Tool

The EINSTEIN methodology is supported by an expert system software tool that guides the user through the whole auditing procedure spanning from data acquisition, processing and estimation to the design and quantitative (energetic and economic) evaluation of alternative solutions.
