| 总结: | Considering the need for designers to develop useful life specifications of the constructive systems that make up a residential building, this study seeks to analyze the specs that are being developed by designers. The research method consisted of a field study. In the first stage, a survey was carried out with design professionals through an online questionnaire divided into direct and indirect questions. Subsequently, designs and project specifications were evaluated to verify the current specification level. Finally, the material specifications of the manufacturers were assessed through searches on the websites of manufacturers and contacts via e-mail about the subsystems: floors, internal and external coatings and waterproofing systems. The selected subsystems are considered essential and of great visual influence on a building, based on Annex C of NBR 15575-1. Among the results, a lack of information provided by the manufacturers about the materials to be specified in the design phase could be observed. That is, most material manufacturers selected for this study didn’t provide data related to durability and useful life, which makes it impossible for designers to comply with the assumptions of the performance standard. |
