A shape grammar approach to climatically adaptable facade systems with real time performance evaluation.

New computational techniques have been introduced to assist the design of adaptable building facades and to help quantify relationships between the building envelope and the environment. Designers increasingly use generative design approach for form-generation of building envelopes, and the organisation of components over a predefined form. In this research an original shape grammar approach for façade systems generation is proposed, with a rule-based method for the creation and exploration of complex shape composites based upon a set of simple initial shapes and predefined rules of composition. This is in order to explore a form finding of set of different building façade configurations before merging generated data into a simulated process of real-time daylighting and heat gains performance evaluation. The developed models adapt via responding to the data-regulation protocols responsible for sensing and processing building performance data in real time. The research reports on the prototype system development and testing, allowing continuous evaluation of multiple solutions and presenting opportunity for further improvement via multi-objective optimisation, which would be very difficult to do, if not impossible, with conventional design methodsN/

Shape grammar and kinetic façade shading systems: a novel approach to climate adaptive building design with a real time performance evaluation.

The concept of a dynamic building enclosure is relatively radical and unexplored area in sustainable architectural design and engineering and as such could be considered a new paradigm. In this research, a novel application of shape grammar approach to design of kinetic façade shading systems has been discussed, inspired by vernacular Vietnamese architectural patterns and parametric generative design. The research reports on the system development and testing, exploring different façade shading configurations and evaluating their performance based on the real-time monitoring of daylight and heat gains, using wireless sensor technology. The strategy for BIM integrated sustainable design analysis (SDA) has also been deliberated, as a framework for exploring the integration of proposed building management system (BMS) into smart building environments (SBEs).N/
