Massing Optimisation with Daylight


This study proposes an algorithm-aided design approach for using daylight in the early phases of architectural design. The main idea is to show how a decision support method can be used effectively to support a massing study with algorithm-aided design tools that use daylight calculation in Building Information Modeling (BIM) environment. To demonstrate the potential use of the algorithm, a mass study design problem is defined for the project area. An interactive session with a designer is then simulated, to show how feedback from the algorithm is used to generate, evaluate and evolve a massing study.

The investigations focus on the development of the use of daylight in architecture using the advantages of computational design tools. For this purpose, performancebased design approaches in daylighting and methods of daylight calculations were examined. An approach has been planned that can propose design solutions by optimizing with Genetic Algorithm that evaluates the results obtained from daylight calculation. In the research, an Algorithm-Aided Design approach was developed by using the visual programming application named Dynamo, which interoperates with Object-Oriented Design based BIM Software Autodesk Revit.



The primary purpose of the method research is to be able to use the quantitative methods in the easiest way possible for users and to seek for maximising the potential of the tools. Correspondingly, basically three main methods have been examined. The first is Algorithm-Aided Design, the second is the Performance-Driven Design approach and finally the Genetic Algorithms to be used for optimisation.

Strategic Variations

Another feature of the system created for the integration of the three main design approaches examined separately during the formation phase of this thesis is the flexibility provided by this appendable integration.This appendable integration system is conceived as an optional removable/appendable system. There are three different combinations of the system which can be operated in various versions. Version 1 provides a complete AAD system, where all three approaches work together. Version 2 includes a version that can be optimized by partial intervention with evolutionary algorithms after evaluating the designer's traditionally designed proposal through daylight calculation. In version 3, there is a version where the form production and then the daylight calculation is performed and the evaluation is left to the designer's choice. These design approaches are designed as a system that can be articulated and can be removed as arbitrary according to design priority.
