Abstract

While BIM is usually associated with new buildings, HBIM is associated with historic buildings, many of which are still in use, particularly those that are less than hundred years old, which constitute a significant portion of the building stock in many European and Middle-Eastern cities. The majority of such buildings have low energy performance; green retrofitting of which can considerably reduce energy consumption and increase their market value. Promising benefits of HBIM include modeling of thermal properties of different building components, thus facilitating environmental simulation of different alternatives, making the success of green retrofitting more likely. Challenges include adapting BIM to model historic building, high modeling effort and cost, and the uncertainty associated with existing condition of historic buildings. A review of the state of ongoing research to overcome such challenges is introduced.
