Evaluation of a residential project in light steel framing according to leed for homes

Abstract

The construction industry is responsible for high energy consumption, high carbon dioxide emissions, high extraction of non-renewable materials, and large generation of solid waste in the world. The use of prefabricated, industrialized, and technological construction methods can reduce environmental impacts generated. Aiming to confirm its environmental benefits, the research proposal was to analyze the sustainability of a residential project in Light Steel Framing (LSF), according to the requirements of the environmental certification Leadership in Energy and Environmental Design (LEED) for Homes of the Green Building Council (GBC) Brazil Homes. For this, it was necessary to apply the Technical Quality Regulation for the Energy Efficiency Level for Homes, achieving the A-level classification in this analysis, with 5.06 final points. Therefore, it was considered the constitution of the building wrap in LSF, the energy efficiency of the materials used, the water heating and lighting systems. In order to obtain the highest level of LEED certification, the project has received suggestions for improvements. The project obtained 60 final points in the analysis, which would allow the achievement of the gold certification seal. The total score in the Materials and Resources topic demonstrates the great benefit of the system in LSF in environmental preservation.
