iRet Software

The EcRoFit project is developing a precision software tool for Building Energy Assessments and Retrofit Recommendations called iRet, which is easy to use, visual and accurate.  iRet will provide additional functionality to the industry-used standard assessment procedure (SAP).  The iRet software application will comprise a building simulation tool with a recommendation system, linked to a database of product and building specifications.

The iRet solution will be available free of charge to companies that participate in either the CPD course or the R&D collaborations.
