Factors Influencing Green Roof Development in Recife, Brazil

In Recife, Brazil, population growth and development of buildings in the Central region generated an increase of almost 70% in the last 20 years due to the large number of companies that have been allocated in the city generating an increase in the local economy and the significant population increase, creating huge heat islands. Due to this, a new technology has been implemented in the real estate market: The green roofs, a technology of sustainable coverage that allows implantation of soil and vegetation in a waterproofed layer on the constructions. The benefits of this technology include the reduction of temperature by consumption of CO₂, a good option for storing rainwater for nonpotable purposes and the possibility of growing organic vegetable gardens for own consumption or sale, generating a new form of income. The aim of the research is to evaluate the factors that interfere with the introduction of sustainable coverage technology of green roofs in the present siting of the city. In this article, the factors that interfere with the implementation of green roof technology in the present siting of the city will be evaluated, focusing on the analysis of internal and external influencing factor. Comparison, historical, statistical data analysis, induction, logical access methods and external and internal influencing factor analysis were used in the research besides the practical development of arguments and graphical representation of research results.
