Aplicação da certificação LEED: estudos de caso em Goiânia-GO

Abstract

Civil construction is one of the segments of the economy that generates the most waste and debris, resulting in damage and major impacts on the environment.Progressively, in order to minimize these effects, sustainable practices have been adopted, from the idealization of the project's functionality, from the way the project is conceived, to the choice of its construction methods and materials. A elesustainable construction aims to meet the needs of society in an economic, socially viable and environmentally correct way, making use of an efficient management of natural resources. In this context, sustainable certifications have been highlighted when evaluating the environmental performance of buildings, seeking to meet the currently more ecologically demanding market. This paper presents two case studies in projects in the city of Goiânia, related to LEED certification in the New Construction category of the LEED BD+C typology: Piracanjuba Administrative Headquarters, already certified, and Soluti Data Center, in the process of certification. The choice for such certification was due to its great relevance and wide adoption worldwide and nationally. The objective was to analyze how the sustainability criteria required by certification were and are being applied in the context of these buildings, raising the main sustainable actions adopted, along with improvements acquired through them and obstacles in their execution. Benefits include increased productivity, reduced risks and increased safety, health, physical and social well-being, reduced operating costs in the medium and long term, and mitigation of environmental impacts. It was concluded that there is a shortage of supply of ecologically certified materials and difficulties in matching design and execution criteria with the American standards, which demands the adaptation of the LEED Certification to the Brazilian Standards and reality. It was inferred that it is necessary to expand the market of suppliers and certified and environmentally tracked materials in Brazil, and that the use of LEED Certification on a larger scale will also result from the change in thinking of construction companies, professionals and society.
