Performance do Edifício: Produtos e Processo para Integração no Projeto Arquitetônico

Abstract

The paper presents a case study on BIM supported design processes and its intersections with discussions about sustainability and energy efficiency simulations. The objective of the study is to identify different levels of detail for BIM models that are compatible with sustainability and energy efficiency simulations. As a result an integrated design, model and simulation process is proposed and validated.

Supporting Tools for Early Stages of Architectural Design

“…Ideas shaped in paper externalize, through fuzzy or vague representations, the designer's intentions in the approach of ill-defined problems. In advanced stages, designs are digitally represented with technical drawings [15], using CAD tools, mainly Autodesk AutoCAD; 3D models, typically using Trimble SkekcthUp [16]; and performance simulations, using software such as Autodesk Ecotect [17]. Performance simulation software includes resources that temporarily change the appearance of the model in different ways, according to the simulated phenomena: airflow is represented by drawing vector fields; lighting simulations involve the discretization of models by sampling and coloring polygon meshes, according to the incident light.…”

“…Architects and the building industry will always be interested to perform simulations in the early stages of design, when design modifications are not as expensive as the intermediate and final design stages [35]. For this purpose, Autodesk introduced Ecotect for the analysis of the buildings environmental performance [36] and proposed Vasari to assist designers in the early stages of architectural design [17]. Paradoxically,Vasari was designed to work jointly with software to support advanced stages of design and construction (i.e., BIM).…”

“…Paradoxically,Vasari was designed to work jointly with software to support advanced stages of design and construction (i.e., BIM). In order to grant its BIM compatibility, Vasari requires the addressing of specific building attributes [17].This automatically drives the designer attention away from the conceptual problems, breaking the mental workflow of the early design stages.…”
