For Barcelona we decided to add higher obstructing structures surrounding the building. We also included buidling rotation and height into the genome or the solver. We set the solver to minimize radiation on the building envelope. COMPARISON BETWEEN GALAPAGOS – GOAT – OCTOPUS – The result obtained through galapagos and goat is very similar,while for octopus is also taken into account the surface of the various floors of the tower. The final result is obtained through the minimization of the useful surface and of the solar radiation We chose Fargo, North Dakota for its cold weather all year long. We set up the building rotation and height for our genome. Moreover we included a segmented line in the equation that Galapagos was controlling to cull out certain parts of the building in order to achieve highest radiation levels on the building facade. COMPARISION BETWEEN GALAPAGOS – GOAT – OCTOPUS – The result obtained through galapagos and goat is very similar, the main difference is the way in which is arranged the upper part of the tower and the central void that is perforated in a very different manner. Regarding octopus the goals is to maximize both the solar radiation and the floor area of the various floors and in this way the tower is appears different than previously found. In the solver set up for Beiut, we obtained an atrium in the center of the building oriented away from the direction of the sun, thus reducing overall radiation on the building and acting as a vent leading hot air out of the building core. COMPARISION BETWEEN GALAPAGOS – GOAT – OCTOPUS – The result obtained through galapagos and goat is very similar, while in octopus it appears different for the fact that we try to minimize the surface of the various plans and solar radiation. The tower produced by octopus has a central void while the galapagos and goat have a void outsid e more carved on the facade.
