“…The green wall (green envelope) using elements of vegetation on the building wall that function to reduce heat gain and cooling loads through shading, cooling transpiration and thermal insulation [34] with potential usage on the west side of the building [35]. The green roof is roof element which using the vegetation on the roof layer that function to reduce the heat gain to surrounding and heating effect to the building [36].…”

“…Green walls as well can regulate the total energy consumption and reduce cooling load also improve indoor thermal comfort [31][32][33][34][35]. In addition, green walls are more effective in moderating outdoor urban climate than green roofs, studies shown street temperature are lower when a green wall is implemented on a near building [36,37]; their impact on a city's climate and indoor comfort however has not been widely investigated.…”

Increased urbanization have many negative effects on human well-being, city infrastructure, electricity usage and the increase of indoor temperatures. A solution may be to retrofit existing buildings, with implementing a vegetated layer to roofs and walls, this may enhance building performance, reduce consumption and improve indoor comfort. Cities with tall buildings may be more adequate to implement a green-wall as it have more area to make impact. This paper examines the energy reduction advantages of adding greenery on buildings in the hot arid climate of Egypt by considering three typical types of residential buildings in the city of Cairo as a case study. Designbuilder software was selected to stimulate the buildings chosen in this research. The results shows that an extensive soil thickness of 15cm performs better in the arid climates. electricity consumption for the base case is 52 kWh/m2 annually when used a traditional external envelop and dropped to 43 kWh/m2 when a vegetated layer added to the whole building (roof & wall), annual electricity consumption reduced by 17% to 25% per annum when added a vegetated layer. In addition to enhancing the indoor thermal comfort by 3 PMV values and indoor air temperature by 5°C.

“…This study consists on modeling this specific green wall type by performing numerical simulations. The calculations are based on a thermohydric model established previously to simulate thermal indoor and outdoor thermal effects of vegetated envelopes [22][23][24]. This model considers heat and water balances on vegetated walls, it has been embedded into a building energy simulation program in a manner to evaluate vegetated buildings energy performance.…”

Green walls and green roofs are innovative construction technologies involving the use environmentally friendly materials. In addition to their aesthetical and environmental benefits, green walls have significant thermal effects on buildings and heat islands within high-density urban areas. In this paper, we study the impact of an innovative green wall system on building energy performance. These green walls have specific composition and particular geometry that can lead to higher thermal performances and therefore more significant impact on building energy performance. The development, validation and prior integration of a hygrothermal green wall model in a transient building simulation tool make possible the assessment of the energy performance of buildings when covered by green walls. The used model was adapted to be the particular forms and composition of the studied green walls. In parallel, this type of green walls has been installed on a one tenth building mockup to be experimented. The aim of the experiment is to measure the thermal effects and to calibrate some parameters of the numerical model. The results highlight the thermal benefits of this kind of green walls in summer condition. They reduce annual energy demand of building up to 37% for hot climates.
