The shape of the building has a major impact on the energy consumption. In the last decades, an increasing number of computing tools are being developed and used by Architects to optimize the shape of buildings and save energy.
This research examines whether the use of a Genetic Algorithm can provide solutions that are functional and aesthetically acceptable.
Reference is made to the software used (Grasshopper, Ladybug Tools, Galapagos) and description of how they work. Some relevant architectural studies are mentioned and finally an experiment is conducted: optimum parameter values related with the shape of a house with total area 100m2 are searched (length-width ratio, orientation, ratio of transparent surfaces on each facade, wall insulation thickness, dimensions of cantilever) with the criterion of minimum energy demand of heating and cooling. Four studies are being carried out in two different locations (Athens, Thessaloniki) and with a total percentage of transparent surfaces of 10%, 20%.
Can the future of Architecture rely on the use of Genetic Algorithms, and if so, what is the role of the Architect in this process?
