Proposição de soluções bioclimáticas visando melhoria do desempenho térmico nas edificações da UTFPR-Dois Vizinhos

Abstract

The accelerated development in large urban cities, coupled with other factors, influence the quality of life. Vegetation is one of the main options to reduce the impact on these urban centers, serving as a second skin for these buildings, generating a great thermal benefit. These green surfaces, known as Vertical Gardens, are being applied as one of the ways to mitigate the effects of the climate, absorbing part of the heat that reaches the buildings (in high temperatures) or providing protection in the form of thermal comfort forming a layer insulation under low temperature conditions. Therefore, the present work aims to propose bioclimatic solutions aimed at improving the thermal performance in the buildings of the Federal Technological University of Paraná, on the Dois Vizinhos campus, bringing diferente types of vertical gardens. For the development of the study, data on the surface temperature of the walls was initially collected to determine the solar incidence of the buildings selected for the implementation of the project at UTFPR - Campus Dois Vizinhos, then, based on the climatic characteristics, aiming at the cost benefit was defined. the type of vertical garden that would be used and defined the best species to use using a table of characteristics, such as growth rate, foliage characteristics, leaf density, presence of flowers, climate it supports and maintenance needs. The last step was the elaboration of 3D models to illustrate how the facades would look after the implementation of the green walls. The proposition was reached that two types of vertical gardens would be used, the Extensive with an indirect Green Facade and the Intensive with Continuous Living Wall, as they demonstrate a better costbenefit ratio. The first type was proposed for the G10 and for the library with the species Thunbergia grandiflora (Tumbergia-azul) and Jasminum azoricum (Jasmineof-the-Azores), and the second for the amphitheater, with the species Dypsis lutescens (Areca bamboo), Calathea makoyana (Peacock Calathea), Chlorophytum comosum (Shadow Chlorophyte) and Philodendron bipinnatifidum (Guaimbê).
