Estudo de modelos de cobertura verde em edificações residenciais de diferentes padrões construtivos no município de Belo Horizonte – implantação e custo

Abstract

The present dissertation presents a study of the implantation of models of green roofs in multifamily residential buildings, of different construction standards, located in the city of Belo Horizonte, Minas Gerais. These files were compatibilized and grouped by means of their characteristics, such as coverage area and constructive standard, thus generating the six standard projects used in this study. The green cover is a constructive system known in the international scope, and in the last decades it has also gained national prominence, this fact has brought about the increase of the studies on this system. For the development of the work, a technical visit was made to the existing green cover in a building of the Unimed Health Promotion Center, located in Belo Horizonte. The visit assisted in the definition of the three models of green roofing to be implanted in the standard projects mentioned herein and in the survey of the engineering services necessary to realize the coverage. From the definition of these services, the implementation costs of the green cover models were calculated, in which the typology of the project, the social charge discharged and the hourly values were considered. The results indicated that despite the high cost of implementation of the green hedging models adopted, model 1 is feasible for the types of buildings adopted, and models 2 and 3 require a larger study on the impact generated by the model on the structure of the building and also a specific study regarding the cost required to maintain the system.
