| Résumé: | In many countries, the design begins by the performance definition of the building parts. The data are then used as a reference to select the viable construction technologies. In Brazil, this practice is still uncommon, mostly in residential projects, because, first, it is defined the architectural characteristics, technological solutions and cost for after consider the technical performance requirements. However, this scenario tends to change due to the publication of the Brazilian performance standard ABNT NBR 15575 (2008) that establishes requirements and quantitative parameters to the five main residential building subsystems (structure, floors, wall partition, envelope and covering, and hydraulic installations), besides to the general requirements for all building. The current version contains requirements for structural performance, fire safety, watertightness, thermal and acoustic performances, functionality, accessibility, environmental impact, durability and maintenance. This standard also considers the concepts of Service Life, Design Life and guaranties periods. The aim of this paper is to present some considerations which must be included to the design process of wall partition for the accomplishment of the performance requirements of ABNT NBR 15575-4 (2008). The considerations are designed to wall partitions, but they can be used as an example to the others building subsystems. This paper was developed based on the bibliographical research and on four case studies, which illustrate how the design process of the wall partition needs to change and what needs to be worked on in order to attend the performance concept and requirements of NBR 15575 (2008). |
