Acoustics and architecture in office buildings: how the site plan and the shape of the building affect the levels of incident noise on façades

Abstract:
 
The lack of soundscape analysis in the early stages of the building construction process is a common practice in real estate developments in Brazil. Acoustical consulting begins after the location and the shape of the building has already been defined, limiting the possibilities of solutions that may reduce the acoustic demands for façades. With the increase in noise pollution in Brazilian urban areas, it is important to emphasize that the acoustic consulting should be initiated during the land prospecting phase in order to improve the possibilities of achieving a more effective acoustical performance of the building. This article aims to evaluate how noise mapping can be used as a tool for decision making about façade design and building location. Therefore, this paper presents a case study in which computer noise simulations were carried out considering the incident noise on a real building, with two alternative proposals for the architectural design which enable lower values of noise incident on the facades and costs reduction.
