description Although the benefits of vegetation are widely known, its use as a facade element remains a very incipient practice. This strategy has become popular due to the promise of improvement on the thermal performance of buildings, in addition to representing an alternative for expanding biodiversity in the urban environment. This paper investigates the influence of green walls, within the Brazilian climate context, on the thermal performance of social housing buildings. The methodology consists of the simulation of the thermal and energy behavior of a multifamily housing building. The simulation is performed with the EnergyPlus® program, including the HAMT model, that takes into account the moisture transfer process through the envelope for three bioclimatic zones provided by the Brazilian standard NBR 15520-2005: extreme winter climate (ZB1), extreme summer climate (ZB8), and a climate considered as the intermediary (ZB3). The results obtained demonstrate a difference in the environments' indoor temperature caused by the two facade arrangements: with and without vegetation. The green wall's use provided a reduction in the indoor temperature of up to 2.8 °C in summer and an increase of up to 1.4 °C in winter. The facade's vegetation worked as a layer of thermal insulation, helping to keep the indoor temperature lower during the day and mild during the night. Therefore, green walls can represent a sustainable and low-cost solution to be implemented in buildings, aiming to improve their thermal performance.

A utilização da vegetação como elemento de fachada ainda compreende uma prática bastante incipiente, mas tem se popularizado devido à promessa de melhoria no desempenho térmico das edificações, além de representar uma alternativa de ampliação da biodiversidade no ambiente urbano. Neste trabalho investiga-se a influência das paredes verdes, no contexto climático brasileiro, sobre o desempenho térmico de edifícios habitacionais de interesse social. Como metodologia, utiliza-se a simulação do comportamento termoenergético de um edifício habitacional multifamiliar, por meio d­o programa EnergyPlus, incluindo-se o modelo HAMT que leva em conta o processo de transferência de umidade através da envoltória, para três zonas bioclimáticas previstas na norma NBR 15.220-2005, clima extremo para inverno (ZB1), clima extremo de verão (ZB8) e para um clima considerado como intermediário (ZB3). Os resultados obtidos demonstram uma diferença na temperatura interna dos ambientes, decorrente dos dois arranjos de fachada analisados: com e sem vegetação. O uso da parede verde proporcionou uma redução na temperatura interna de até 2,8 °C no verão e um aumento de até 1,4 °C no inverno. Observa-se que a vegetação na fachada ajudou a manter a temperatura interna mais baixa durante o dia e amena durante a noite. Logo, as paredes verdes podem representar uma solução sustentável e de baixo custo a ser implantada às edificações, visando melhorar seu desempenho térmico.
