“…Scenarios for climate, building type, building age, and green roof plant coverage Thermal performance of green roof assemblies depends on the local climate because the green roof material properties are highly dependent on outdoor environmental conditions [19,27]. A study of the green roof thermal performance showed that the material selection for green roof assemblies is more important in climate zones 4 and 5 than the material selection for buildings located in climate zones 2 and 3 [27].…”

a b s t r a c tThis study quantifies the influence of green roof plant coverage on the building energy consumption and the substrate energy balance components. The analysis started with the implementation of a green roof model that accounts for the effects of plant coverage into the U.S. Department of Energy (DOE) building energy simulation program, EnergyPlus. Using the DOE reference building models, thirty different cases were simulated considering different green roof plant coverage, building type, and building age for two different climates. The results indicated that the green roof substrate surface temperature decreases with increasing plant coverage. This temperature decrease is primarily due to the decrease in the amount of absorbed solar radiation on the substrate surface and also an increase in the substrate surface evaporation. For the base-case simulation, due to the plant shading effects, the total daily received radiation at the bare-soil surface is 32% (6.2 kWh m −2 ) higher than that at the fully-covered green roof substrate surface. Furthermore, the annual cooling (heating) load decreases (increases) with the rate of 13 (0.88) kWh m −2 of plant coverage area. The aim of this study is to show the importance of considering plant coverage in green roof simulations and building energy demand predictions.

“…A study evaluated the green roof performance under mild winter conditions, and concluded that the influence of green roof assemblies is unimportant when focusing specifically on the heating loads [6]. However, the thermal performance of green roof assemblies may vary for different climate zones [5], so the results from regions with mild winters may not properly represent regions with cold winters. Another study, conducted in a cold climate, measured the thermal performance of a green roof versus a gravel roof.…”

“…Os estudos de simulações com modelagem são comparados com experimentos e coleta de dados observados e referem-se tanto para avaliação da capacidade de retenção do escoamento (LOCATELLI et al, 2014), como para predizer o desempenho do arrefecimento por perda de calor latente, que está condicionada a espessura do substrato (METSELLAR, 2012). Independentemente das zonas climáticas, o resultado das simulações mostrou que o tipo de vegetação influencia significativamente no saldo de radiação (ZHAO et al, 2014).…”

GLOBAL EFFECTS OF TEMPERATURE AND PRECIPITATION IN GREEN ROOFSABSTRACT: The effect of temperature, solar radiation and rainfall directly affects the cities, especially densely occupied areas, with impacts on the formation of heat islands and urban flooding. The purpose of this article is to evaluate the influence of factors and meteorological elements in the behavior of green roofs installed in more than 100 countries from the climatic classification of Köppen-Geiger. They were mapped more than 170 scientific papers published in national and international journals with experimental and modeling studies applied on green roofs. The results indicate a predominance of 70% of studies with green roofs in temperate areas, 65% of research related to thermal comfort and the quantity and quality of runoff retention. The researches reveal a relative influence of geographic factors that condition the climatic elements of temperature and precipitation in the capacity of runoff retention in green roofs, however, they are able to condition cooling systems as they delimit thermal effects caused by temperature variations present in surfaces green roof.
