Resumo
This paper describes the construction of an information flow that
combines parametric modelling and genetic algorithms to optimise
both the total weight of a structured steel roof and the shape of its
surface to maximise the generation potential of photovoltaic energy.
Through the systematisation of a design process using genetic algorithms
integrated with generative design as an architectural design method, architects can
work with problem parameterisation, going one step further than the mere formal
proposition of solutions. As a result, we present a process in which there is a
dialogical relationship between the architect and project in a continuous flow of
information in the initial steps of the design process, guided by predefined
optimisation objectives. Therefore, it is relevant to note that the designer accepts a
reduced creative control over the final shape in favor of control over the core
principles that constitute the optimisation algorithms. An approach that involved
the designer in a process of post computational processing evaluations is also
highlighted, giving him better support to discuss and analyze the design options.
