The E-PASS energy performance assessment tool is an easy-to-use tool for the assessment of various refurbishment measures into the residential buildings. The user is supported to configure the modelled building easily in its “as is”-state and quickly apply a set of selected refurbishment measures to the “after”-state. The key performance indicators (kWh/m2, kgCO2/m2, operational costs, payback time) and the impact of the selected measures can be viewed in the same interface.
