Abstract

Building renovation plays a huge role in reducing CO2 emissions and energy demand. To understand the effects of different renovation strategies, expert users and decision makers need to explore renovation scenarios both spatially and temporally. The ongoing GEWISS project aims to do this by providing a GIS (Geographical Information System) to visualize energy demand per building as well as an interface to simulate possible renovation paths to its users. This white paper presents a novel proposal to simulate future renovation paths by utilizing different user scenarios containing multiple selection criteria to rank current building stock and consequently use optimization to pass them through the user selected renovation strategy in the most optimal way.
