Abstract: This paper presents a workflow to support the decision making for identifying building energy efficiency measures for multiple buildings in a neighborhood. The workflow consists of a method to extract geo-spatial information, compute renewable potentials and energy demands and an optimization model to evaluate the most suitable retrofitting scenario in terms of envelope and system update based on multi-criteria decission making. The developed method is applied on a case study pertaining to an existing rural area. Modelling results include best performing options in terms of CO2 emissions while minimizing the resulting costs of the possible energy system solutions are derived.
