Thermal behaviour of indoor spaces under the influence of green envelopes

Green envelopes are a means for vegetation to become an integral part of the building and its systems such as the passive cooling. However, the dynamics that sustain a good thermal performance of these envelopes depend on many variables. This article aimed to identify, through the systematic review...

description	Green envelopes are a means for vegetation to become an integral part of the building and its systems such as the passive cooling. However, the dynamics that sustain a good thermal performance of these envelopes depend on many variables. This article aimed to identify, through the systematic review of recent literature about the topic, the thermal behavior of internal built environments under the influence of green envelopes and which are the possible performance variables according to its features. The analyzed papers show that the temperature reduction of indoor spaces is significant, being more pronounced in the case of green walls. The thermal performance of green envelopes depends on variables such as the vegetation type, leaf density, substrate’s composition, etc., highlighting the climatic features despite the fact that most studies focus on results from other variables. It was also possible to verify weak spots of the current knowledge, like the gaps regarding the weight of the substrate’s humidity in green roofs’ cooling and the lack of investigations that compare the green roof’s performance with ceramic tile or fibro cement roofs. The analysis of the variables identified that these exert multifaceted relations between themselves, which made evident that settling hierarchies between these are neither possible nor prudent. The study of the coherence between the variables is more important than determining its hierarchy, as well as this action, must precede the definition of characteristics of a given green envelope to be installed in a specific place.

As envoltórias verdes são um meio de tornar a vegetação parte integrante da edificação e de seus sistemas, tais como o de resfriamento passivo. No entanto, as dinâmicas que sustentam o bom desempenho térmico destas envoltórias dependem de diversas variáveis. O objetivo deste artigo foi identificar, através de revisão sistemática da literatura recente sobre o tema, o comportamento térmico de ambientes construídos internos sob a influência das envoltórias verdes e verificar quais são as possíveis variáveis de desempenho térmico, conforme suas características. Os trabalhos analisados mostram que a redução de temperatura do ambiente interno é significativa, sendo mais acentuada no caso de paredes verdes. O desempenho térmico das envoltórias verdes depende de variáveis como o tipo de vegetação, densidade de folhagem, composição do substrato, etc., destacando as características climáticas, apesar da maioria das pesquisas focar em resultados de outras variáveis. Foi possível, também, verificar pontos frágeis do conhecimento atual, como as lacunas a respeito do peso da umidade do substrato no resfriamento de coberturas verdes e da falta de estudos que comparem o desempenho de coberturas verdes com coberturas de telhas cerâmicas ou de fibrocimento. A análise das variáveis identificou que estas exercem entre si relações multifacetadas, o que tornou evidente que determinar hierarquias entre estas não é possível e nem prudente. A análise da coerência entre as variáveis é mais importante do que a determinação de hierarquia entre as mesmas, bem como esta ação deve preceder a definição das características de uma determinada envoltória verde a ser implantada em dado lugar.
