Avalia??o p?s-ocupa??o de edifica??es constru?das no sistema light steel framing.

O sistema Light Steel Framing (LSF), uma alternativa industrializada e racionalizada de constru??o de estruturas, vem ganhando lentamente espa?o no Brasil em edifica??es para diversos usos. No entanto, ainda s?o necess?rias algumas adequa??es dos projetos para a melhoria de sua efic?cia e para a aceita??o por parte dos usu?rios, porque a concep??o do sistema teve origem nos EUA, e preserva a linguagem arquitet?nica t?pica daquele pa?s. Neste trabalho avaliam-se a percep??o e a absor??o do sistema construtivo LSF por parte do usu?rio, tendo por crit?rio seu n?vel de conhecimento e satisfa??o em rela??o ao novo sistema e sua familiaridade com o uso e a manuten??o desta nova tecnologia, comparados com a sua experi?ncia em edifica??es que usam as tecnologias tradicionais, culturalmente j? assimiladas; e o estado de conserva??o e as transforma??es pelas quais a edifica??o passou em fun??o das necessidades surgidas com o tempo. A metodologia utilizada na pesquisa envolveu a Avalia??o P?s-Ocupa??o, com visitas ao ambiente constru?do, avalia??o in loco e entrevistas com usu?rios utilizando-se question?rios como instrumento de coleta de dados. Neste artigo tamb?m se sistematizam recomenda??es que servem de refer?ncia para opera??o, uso e manuten??o das edifica??es e, principalmente, para basear decis?es de projeto de edifica??es com LSF e, dessa forma, garantir a qualidade e ampliar a aceita??o das constru??es com este sistema no mercado nacional. Faz-se ainda uma avalia??o t?cnica do comportamento de edifica??es constru?das com o LSF incluindo itens como seguran?a, qualidade, durabilidade, necessidade e periodicidade de manuten??o, conforto, adapta??o ?s fun??es e o porqu? das patologias. Comprova-se que existem ainda algumas adapta??es a serem feitas para adequar a t?cnica de constru??o com LSF ?s condi??es clim?ticas, econ?micas e sociais, aos costumes e ? cultura brasileira da constru??o. A retroalimenta??o de informa??es por parte do usu?rio foi essencial nesse processo de avalia??es por ser um agente capaz de n?o somente detectar eventuais problemas no uso e na manuten??o da edifica??o, mas tamb?m por apontar qualidades essenciais do sistema de constru??o.The system Light Steel Framing (LSF), an industrialized and rationalized alternative for the construction of structures, has been slowly gaining space in Brazil in the construction industry for several purposes. Notwithstanding, the building designs still need some adjustments in order to improve their effectiveness and to achieve the users? acceptance because the system?s conception came from USA, and maintains that country?s typical architectonic language. In this article the users? perception and absorption of the constructive system LSF are evaluated, using as a criterion their level of satisfaction and awareness about the new system and their nearness to the use and maintenance of this new technology, as compared to their experience in using the traditional construction technologies, which have already been culturally assimilated; and the buildings? conservation condition and the transformations they had to go through along the time. The investigation methodology involved the Post-Occupancy evaluation with visits to the construction environment, and in-loco evaluation, and interviews with the users to collect data, by using questionnaires. In this article it is also systematized recommendations that can be used as references when using and maintaining the construction, and specially to serve as a base to decisions when designing constructions with LSF and so guaranteeing the quality as well as raising the acceptance of constructions with this system in the Brazilian market. A technical evaluation of buildings constructed using LSF was made, including features like safety, quality, durability, maintenance necessities and periodicity, comfort, adaptation to the functions and the causes of pathologies. It is verified that there are still some adjustments that need be done in order to fit the LSF construction technique to the Brazilian climatic, economical, and social conditions as well as to its construction culture and practice. The information feedback from the users was essential in the evaluation process because it is an instrument able to not only detect possible problems during the use and the maintenance of the edification but also able to point out essential qualities of the construction system
