This paper comments on the formulation and evaluation of facade elements that use the characteristics of the fractal geometry, and has the objective to investigate if these elements improve the use of daylight. Thus, ten elements of facades were developed from linear fractals rules, using three-dimensional modeling tools, parametric and plug-ins, that allowed to recreate some of the composition rules of the fractals.

Este trabalho aborda a confecção e avaliação de elementos de fachada que utilizam as características da geometria fractal, e tem como objetivo averiguar se estes elementos potencializam a utilização da luz natural. Desta forma, dez elementos de fachadas foram desenvolvidos a partir de regras de fractais lineares, utilizando ferramentas de modelagem tridimensional, paramétricas e plug-ins, que permitissem recriar algumas das regras de composição dos fractais. Esses elementos foram submetidos em uma composição homogênea em um ambiente virtual construído para simulações dinâmicas, sendo avaliados nas orientações Norte e Sul. Seus resultados foram agrupados em planilhas e gráficos, possibilitando uma avaliação individual de cada composição presente nos diferentes elementos. Os resultados encontrados mostraram que os elementos desenvolvidos com as características fractais apresentam respostas diferenciadas para cada elemento e iterações, demonstrando que a utilização desta geometria como uma forma de controle solar, pode potencializar as condições lumínicas do ambiente interno, além de ampliar o leque de alternativas para o design de componentes compositivos para fachadas. Com o algoritmo desenvolvido, também pode-se selecionar os componentes com mais potencialidades para a determinada localidade simulada, permitindo que em futuros estudos ele possa ser alterado em diferentes parâmetros, potencializando suas atribuições como elemento de fachada.
