Building performance modelling for sustainable building design

Sustainability has become a significant aspect of real estate and has been integrated into the design, construction and operation of buildings. Now, emerging from the various initiatives around the world, the building information modelling (BIM) approach has been seen as a method that might deliver substantial gains in terms of designing and assessing the environmental cost of buildings. Various research methodologies have been adopted, including a literature review exploring the benefits and challenges of BIM and of using a building performance modelling software (BPM) called Ecotect for sustainable building design. Finally, it introduces a design tool analysis of a case study using Ecotect to evaluate various what if scenarios on a proposed multi-use building. The output revealed that BPM delivers information needed for enhanced design and building performance. Recommendations such as the establishment of proper mechanisms to monitor the performance of BPM related construction are suggested to allow for its continuous implementation. This research consolidates collective movements towards wider implementation of BPM and forms a base for developing a sound BIM strategy and guidance
