Building performance simulation as a design tool for refurbishment of buildings

This paper attempts to outline the current state-of-the-art regarding the use of building performance simulation as a design tool for refurbishment of buildings. This is illustrated by means of three recent studies for conversion of historical buildings (an early 20th century factory, and a water mill and a former church both dating back to the 14th century) into an office development, a museum gallery and a concert hall respectively. The paper elaborates the modeling and simulation work that was carried out to support the design teams of the three projects. This includes a discussion on how the simulation results were transformed in relevant design information. The paper finishes by indicating directions for future work that is needed to be better equipped in order to address design problems in the field of construction or restoration of buildings and their heating, ventilation and air-conditioning systems.
