Abstract

There are increasing numbers of building modelling and simulation tools available for green building design and analysis. Proper selection of the tools determines the effectiveness and reliability of the simulation. This article reviews some state-of-the-art simulation tools in relation to project stages and performance outputs. Then, an on-going University-Industry collaborative research on developing a Green Mosque in Johor Bahru, Malaysia using building modelling and simulation is discussed. The original building design as proposed by the architect was modelled for building performance simulation. Shadow casting and surface solar insolation were simulated using Autodesk Ecotect Analysis to determine the area exposed critically to direct sunlight radiation. Then, daylighting simulation was performed in IES Radiance. The same building model was also employed for CFD simulation by IES Macroflo and IES Microflo. The natural ventilation air flow in the Main Prayer Hall was investigated. Several independent design variables were identified and tested to improve the building performances. Eventually, review of the building design was made to achieve green design. The findings indicated that prior to the simulation experiment; some of the initial green design concept was actually not performing as expected. Therefore, building modelling and simulation during the early or pre-design stage is very crucial to prove and improve the building performances in order to develop evidence-based building design.
