Our proposal is to enhance information on the actual building stock and on barriers and drivers that influence the decision of public or private buildings ‘owners toward renovation. With this information and with dedicated services, local authorities could persuade owners to undergone renovations on their buildings. We developed a methodology that allows to create a GIS model and tools quickly for virtually every Italian municipality and already tested in an Italian medium size municipality. With these tools it is possible to select buildings that need most the renovation and buildings that could be more easily renovated, considering barriers and drivers.
