With input from several Architectural practices in Denmark we are currently working on an application which models and evaluates alternative commercial tower typologies in real-time, giving instant performance feedback during the early design stages where the most important decisions are made but also when the least amount of time is available.
Evaluation criteria include solar gain, heat loss, structural performance, gross floor area, etc… as well as site specific impacts such as shadow casting of neighbouring buildings. This quantitative performance data (which can be numerically optimised) is then combined with the qualitative aspects of design such as aesthetics, social impact, iconography, etc. when making informed decisions in how to progress the design. Different modes of representation including physical models are also implemented to allow integration with existing tried and tested methods of working.
As the design space is so large at concept design stage, modelling variations in different tower ‘types’ has meant us going beyond traditional optimisation of numerical sliders in parametric models, and as a result this has opened up interesting avenues of research.
