Floor separating independent residential units. In accordance with the acoustical criteria, which are quantitative, are given in terms of the weighted values determined in accordance to ISO [2] and ISO [3]. Internal and external walls. Two requirements are recommended in accordance with Table 1: The introduction of the new standard is certainly a big step for the Brazilian market.

Slab floor, or another element, with ot without nbr 15575 floor covering, without acoustic insulation. If the floor is composed of different subsystems any subsystem can be assessed separately in laboratory and results can then be combined.

Sound Insulation 1575 external walls. Part 3 – Requirement for internal floors systems Regarding the requirements for the internal floors systems a large number of additional standards is referenced such as: This article aims to share the most important information contained in the standard published in Portuguese only, presenting a review of the parts of the standard that concern acoustics in terms of the requirements, the criteria and the nbr 15575 of evaluation by measurements in the laboratory or the field.

Residential dwellings up to five floors — Performance. Internal and external walls 1.

NBR 15575-1 – Edificações habitacionais – Desempenho – Requisitos gerais

It was verified that the system with higher air gaps number had a better performance on fire resistance, and that the acoustic performance was very similar between the two systems. For the first time in the Brazilian civil construction the standard NBR establishes requirements, criteria and evaluation methods for determining performance of residential buildings in order to provide acoustical, thermal and lighting comfort and acoustical privacy to its occupants.

Based on weighted values for sound insulation the acoustics performance of residential buildings can be classied nbr 15575 three levels of performance: Two requirements are recommended in accordance with Table 1: English pdf Article nbr 15575 xml format Article references How to cite this article Automatic translation Send this article by e-mail.

Part 6 – Limitation of hydrosanitary noise. The performance of a building is defined by requirements, criteria and evaluation methods for a certain nbr 15575, e. The introduction of the new standard is certainly a big step for the Brazilian market. No acoustical performance adressed. In order to be successful the Nbrr will require that adequately trained professionals are at hand and involved not only for in-situ or laboratory measurements but also in research and in activities that can transmit this knowledge to the Civil Engineering sector.

After the publication of NBR ABNT, standard, it became necessary that the constructive ngr used in residential buildings go through verification processes concerning the performance requirements.

A computer simulation was performed using the EnergyPlus programme. William D’Andrea Fonseca, Dr. Jaime Mosquera Sanchez, Dr.

The most important requirements, criteria and methods for assessment will be introduced subsequently, following the division proposed by the NBR [1]. Within the scope of habitability, the standard specifies that these systems must have an adequate acoustic performance.

This aim of this study is to evaluate the simulation procedure proposedby NBR ABNT, a to assess the thermal performance of dwellings.

The criteria to guarantee the maximum nbr 15575 pressure level in the residence can be determined as: Floor of residential nbr 15575, positioned under commum area mbr. The comparison of ngr indicatedthat the conditions of the ground slab contact conditions selected to simulate the thermal performance of the building strongly influenced the constructive system analysis.

Parte 4 – Nbr 15575 for the vertical internal and external systems. Internal and external walls. Acoustics — Rating of sound insulation in buildings and of building elements, International Organization for Standardization. The comparison between the two procedures showed a difference in the performance results of the dwelling, considering the same building component.

Additionally to the brief review some comments on the standard will be given.

Impact noise sound insulation of terrace floors accessible to the public. Airborne sound insulation of terrace floors. Structural systems No acoustical performance adressed.

Slab floor, or another element, with ot without the floor covering, with acoustic insulation.
