A conceptual model for the design process of interventions in healthcare buildings: a method to improve design

The fast advance of medical technology and changes in the users profiles require new configurations of delivering care and new spaces to support and contribute to the implementation of new activities. To encourage and facilitate the continuous upgrade of existing healthcare buildings through interventions, it is important to establish methods to improve the design process, due to the great complexity involved in the healthcare architecture. This paper reports a conceptual model of the design process for interventions in healthcare buildings, to help the education of architects and also to assist inexperienced designers in managing the process and improving it. Data were collected through a literature review and a case study in a design office skilled in healthcare architecture. The model consists of five macrophases, divided into phases and subphases, and includes the various relationships between them, characterizing the process as generally cyclical, but with chances of break and retreat. It serves as a basis for the development of projects in this sector and can be suitable for the peculiarities of each case.

Life cycle assessment and environmental-based choices at the early design stages: an application using building information modelling

ABSTRACT Despite the apparent simplicity of existing BIM-LCA tools, there is a lack of integration with the main BIM software, and the double-effort of design development and parallel simulations is a barrier to their implementation in the design process. Moreover, simplifications on these tools may provide misleading results to the designer. The main aim of this research is to develop an integration interface of manufacturer-based LCA data into a BIM platform by combining applications of existing and consolidated tools (namely, Autodesk Revit and Dynamo, and Microsoft Excel), in order to obtain environmental profiles for decision-making in the initial design stages, requiring less time, effort and ad hoc experts. The methodological procedures were aggregated into the following system development and testing phases: (a) input data organization, (b) creating new parameters on BIM software, (c) visual programming, (d) results analysis for decision-making and (e) simulation of social housing. The results of the developed tool provided complete results automatically, not requiring the designer to make changes in the software or interfaces. Some limitations were identified during development and application, due to the lack of LCA data availability by manufacturers, the complexity of data programming importation and extraction on BIM software for different construction subsystems, and the complexity of LCA results analysis and understanding encountered by non-experts. Regarding the latter, the research concluded that broad knowledge dissemination is still necessary to improve awareness regarding this environmental assessment methodology, in addition to determining the most advantageous environmental performance parameters, as a reference point for comparison.

METHODOLOGICAL DISCUSSION OF INSERTION AND EXPORTATION OF LCA DATA EMBEDDED IN BIM ELEMENTS

The Life Cycle Assessment (LCA) methodology can be used to quantify, in the design phase, the impacts of a product throughout its life cycle and to determine which building components have the highest potential impacts. However, such a method has often been avoided due to the need for detailed input data and the complexity of the available tools. For that reason, although LCA is increasingly present in the construction sector demands, professionals continuously pursue new ways to incorporate such methodology to the building design and construction processes, as simple and uncomplicated as possible. A promising possibility is the incorporation of building systems LCA data in the BIM software tools. Numerous limitations of BIM-based LCA have been identified over the years. For instance, the complexity of LCA software tools, particularly as regards the data input and interpretation of results, and the interoperability issues, all need to be overcome. Once BIM models are composed of smart objects, which represent construction elements with encapsulated intelligence, they are expected to be where LCA data could be applied. In this paper a conceptual and methodological discussion will be developed on the practical possibilities of inclusion and export of LCA data embedded in BIM elements, focusing on Autodesk Revit software and its features. Such a discussion will take place by exploiting technological possibilities of such software and evaluating the possibilities of development and modification of parametric elements and families, as well as the further export potential of such embedded LCA information. The main goal is the construction of a robust theoretical framework that will precede the future development of a methodological BIM-LCA integration tool by the exploitation of the features available in the existing software.

Arquitectura e industrialización de la construcción en la obra de João Filgueiras Lima – Lelé

The results of a scan modeling are shown in addition to the study, review and discussion of architectural form. The basis for the expansion of an exploration into new morphological developments, such as the study of gradients and fragmentation processes scale in tissue formation and modular landscapes (and not just growth with relatively developed modules usually fixed sizes) are considered. They stand out as relevant and complementary notions of fragmentation and modular assembly based on units of different size and shape, in a minimalist framework of assimilation. Along with the above, cases are shown which were generated from exploring these principles applied to proposals developed by the author and students from commissions in the area of fractal geometry and Module Form Workshop City shown, related to the theme of vernacular architecture and urban fabric
