| Riassunto: | In order to improve buildings performance, following a worldwide trend, NBR no. 15,575/2013, known as Performance Standard (PS), is composed of six parts and defines minimum, intermediate and superior criteria and methods for evaluating residential buildings efficiency. Due to the complexity involved in meeting the standard, this article presents results of a case study carried out during the production stage of a multi-floor residential project that sought to meet PS at the upper level. This research aimed to analyze quanti-qualitatively the standard requirements and criteria of performance and to identify the main changes made in the building studied, in relation to works traditionally carried out by the construction company. The research method involved document analysis (PS, designs, manuals, memorials), interviews with designers and builders, and observations of the construction site. The results indicate that out of 155 criteria, only 26 established the three levels of attendance: lower, intermediate and upper. The quantitative analysis, in terms of attendance complexity, indicates that the most complex part consists on general requirements, followed by: structural systems, floor systems and sealing systems. Although the number of criteria with three levels is not very representative (16%), the performance difference between lower and upper levels is expressive and can represent a great differential for a better service. The main changes and challenges for the implementation of PS consisted on significant number of laboratory experiments, the relevant role of Technological Evaluation Institutes, and the adoption of new technologies or materials not used previously by the construction company. |
