Modern buildings are characterised by the use of glazed Multi-Skin Façade (MSF) that are aesthetically appealing; consider the re-development of the former CUB site, Swanston Street Melbourne. However, leading researchers in the School of Engineering, University of Melbourne have found that buildings with glazed façade systems could consume energy for heating and cooling up to 60-70% of operational costs. The challenge is to have energy efficient buildings that still look impressive.
