Panorama de uma construtora do município de Russas – CE acerca da implementação da Norma de Desempenho - NBR 15575

Abstract

Building performance-focused housing is still a challenge for some building companies. The Performance Standard sets out requirements and criteria that must be met by all housing buildings to meet user requirements. In this context, the present work has the objective of knowing the current scenario and main challenges regarding the attendance to NBR 15575/2013 in a construction company operating in Russas - CE. For this, were interviewed, in addition to the company, users of real estate, which are the main interested in the quality of housing delivered by the construction company. The interview with the company sought to identify the adequacy to the requirements that the standard establishes and to understand the difficulties that still exist after six years of NBR validity, besides discussing the advantages and disadvantages that can be highlighted by the company, regarding the publication. With regard to users, the interest was to know their main dissatisfaction about the quality of housing, to, after identifying them, verify if the systems meet the minimum requirement required by the Performance Standard. The main challenges to highlight the service, alleged by the construction company are: lack of in-depth knowledge of all criteria and requirements required by the NBR, shortage of specialized laboratories and specific equipment in the region and increased costs in the construction process. Nevertheless, the company recognizes the advantages that the NBR publication brought to the sector, summarized in establishing parameters to be followed, enabling the delivery of housing with a certain quality standard. Regarding the users of real estate, dissatisfaction was expressed mainly about the thermal comfort provided by the dwellings they occupy. In possession of the information it was found that, although the company does not have proof of performance, the houses analyzed in the sample, built by the company, meet the minimum requirements required by the Performance Standard with respect to the thermal comfort of properties, obtaining satisfactory values for the thermal transmittance of the external vertical sealing system and roof, thermal capacity of the external walls and openings areas for ventilation of long-term environments, also proven by computer simulation
