Layout Synthesis for Symmetrical Facades

“…Within the project, a greedy solution have been proposed [2] but it is able to generate only one solution without applying any notion of optimality. We have presented our first approximation for solving the layout synthesis of symmetrical facades using a declarative approach that includes:…”

“…The problem includes three characteristics never considered simultaneously: It deals with the allocation of an unfixed number of rectangular parameterizable panels that must not overlap, frames (existing windows and doors) must be overlapped by one and only one panel, and facades have specific areas providing certain load-bearing capabilities that allow to attach panels. As far as we know, only a previous work by the authors that uses a greedy approach [2] have been proposed to address this problem. That solution, however, generates only one valid solution for a given facade specification and does not involve optimality criteria.…”

Thermal estimations to support buildings retrofit: Which envelope to manufacture?

“…In this section we present some estimations of energetic performance using a constraint-based prototype [13] implemented on Java that uses a greedy approach to generate compliant layout plans as explained in [12]. Each case is part of the site La Pince in the commune Saint Paul-les-Dax in the area of Landes, France.…”

“…Instead, we focus our attention on how to discriminate between good and not so good solutions given their heat transfer between the interior and exterior of the building and their associated cost, and let the aesthetic aspects to the final user. Further information on how to generate these envelopes is found in [12] and information on layout synthesis may be found in [10].…”

External buildings retrofit: Employing guillotine cuts for aesthetic envelopes

“…In two previous works, we have already developed consistent algorithmic solutions to the problem: the first using a greedy approach [2] and the second using a constraint-based approach [3]. However, the generated envelopes solutions from these algorithms do not count with aesthetic aspects needed for the retrofit (such as symmetry).…”
