From Macro to Micro - An integrated algorithmic approach towards sustainable cities

Abstract

As urbanization rapidly increases towards concerning levels, new methodologies and approaches are required to shape future cities. This research combines passive design approaches with building performance simulation in the same algorithmic description, to highlight the bidirectional impact of the building and the urban context in which it is inserted. To that end, the proposed workflow employs an algorithmic design tool along with validated analysis engines, to assess incident solar radiation and comfort metrics. We apply this methodology in a case study, exploring alternative building geometries to mitigate the consequences of uninformed design decisions in the environment. Results show that the application of passive design strategies can be done within early design stages, allowing a continuous workflow from project to construction while minimizing time and labour requirements regarding building efficiency.
