Problem definition The use of Building Performance Simulation(BPS)to support building design has long been the‘holy grail’of building science *** can also be used during construction and operation of buildings,for instance supporting rating and certification,optimal control,or fault emulation,but design support is particularly interesting as this is where the foundations for future building performance are *** underlying premise is that good predictions of future building performance can inform and improve design decision-making,and thus help to create buildings that are more energy efficient,more comfortable,and overall perform better than buildings that are designed without such *** on BPS for.design support has been carried out since the emergence of building science as a separate area of research in the 1960s(Markus et al.1972;Clarke 2001;Maver 2002;Augenbroe et al.2004).
