Análise das causas raízes que dificultam a adoção de telhados verdes nas edificações brasileiras com utilização da metodologia Delphi

Abstract

Green roof systems are considered a sustainable practice to mitigate the adverse effects of urbanization in densely populated areas. Green roofs mitigate urban heat islands, retain rainwater and generate peak flow and runoff, improve urban air quality, absorb noise losses, increase the thermal efficiency of buildings and provide a pleasing aesthetic effect as buildings. Germany, France, UK, Hong Kong, USA, Canada, Australia, Singapore, Japan and other countries are encouraging the installation of green roofs during the construction of new buildings and adapting the old ones so that this technique becomes a reality in the near future. However, the use of this type of coverage in developing countries and regions is still not widespread. The objective of this research is to identify root causes that hinder the adoption of green roofs in Brazilian buildings. Understanding the deep barriers is important to promote the implementation of green roofs on a large scale and consequently, to achieve the benefits of their installation. This research was developed through a review of technical literature and field research (questionnaire) with experts using the Delphi Methodology approach. The essential results are that the main barriers to the adoption of green roofs in Brazilian buildings are associated with problems of knowledge and knowledge of the technology and that there are barriers associated with all stages of the building's life cycle, including the planning phases and design, construction and operation and management.The abstract should contain similar information than in "resumo" and must be written in english.
