“…They also found that, with appropriate use of greenery on buildings, the micro-climate can improve noticeably. Perini et al [34] have also measured the ambient air temperature differences in the vicinity of three vertical greening systems (direct, indirect and LW). The results show no remarkable air temperature differences for all of the greening systems at the distance of 10 cm to one meter away from the façade.…”

“…Perini et al [34] have also investigated the correlation of air cavity thickness with thermal insulation properties provided by green walls. They found that direct façade greening and living wall (with 4 cm air cavity) are more effective on reducing the wind speed around the building façade than indirect green wall (with 20 cm air cavity) due to shorter vegetation-wall distances.…”

“…Perini et al [34] conducted a field measurement in the Netherlands, a temperate climate, and compared the surface temperature differences between a bare wall and three different vertical greening systems. Small temperature differences were obtained for indirect (20 cm air cavity) and direct (attached) green walls.…”

“…Anderson et al [6] investigated and compared 21 algorithms that calculate heat index as a function of temperature and relative humidity, or dew point temperature. These authors pointed out that NWS algorithm [12], presented in the flowchart below (Fig.2), had the best fit Steadman's table [11], and as a result it was chosen to calculate heat index in the present work.…”

“…However it is important to highlight that due to the common tall characteristics of buildings, facade areas are substantially larger than those from rooftops. Thus, it is expected a more pronounced effect of green walls in attenuating housing temperatures [6]. However the combination of green roof and green walls is likely to provide a better thermal performance in the building envelope.…”

Abstract. Increased urbanization has led to a worsening in the quality of life for many people living in large cities in respect of the urban heat island effect and increases of indoor temperatures in housing and other buildings. A solution may be to retrofit existing environments to their former conditions, with a combination of green infrastructures applied to existing walls and rooftops. Retrofitted green roofs may attenuate housing temperature. However, with tall buildings, facade areas are much larger compared to rooftop areas, the role of green walls in mitigating extreme temperatures is more pronounced. Thus, the combination of green roofs and green walls is expected to promote a better thermal performance in the building envelope. For this purpose, a modular vegetated system is adopted for covering both walls and rooftops. Rather than temperature itself, the heat index, which comprises the combined effect of temperature and relative humidity is used in the evaluation of thermal comfort in small scale experiments performed in SydneyAustralia, where identical timber framed structures prototypes (vegetated and non-vegetated) are compared. The results have shown a different understanding of thermal comfort improvement regarding heat index rather than temperature itself. The combination of green roof and walls has a valid role to play in heat index attenuation.

Vertikale Begrünung kann einen wesentlichen Beitrag zu einer nachhaltigen Stadtentwicklung leisten. Denn Begrünung kann nicht nur die bauphysikalischen Eigenschaften von Gebäuden verbessern und als Schadstofffilter zur Verbesserung der Luftqualität beitragen, sondern auch großen Einfluss auf die betroffenen Menschen haben. Eine Begrünungsmaßnahme im Rahmen einer Bestandssanierung oder bei einem Neubau durchzuführen, ist nicht zuletzt von den entstehenden Kosten und den möglichen Nutzen abhängig. Das Ziel der durchgeführten Forschung besteht darin, ein Basismodell zu entwickeln, mit dem in weiterer Folge objektbezogen die Kosten und Nutzen für wandgebundene Begrünungssysteme abgeschätzt werden können. Hierzu wird für jedes System ein gesamter Lebenszyklus von der Errichtung über die Nutzung bis zur schlussendlichen Entsorgung betrachtet. Aufgrund der fehlenden Messbarkeit und quantitativen Bewertbarkeit vieler positiver Auswirkungen von Gebäudebegrünung kann derzeit kein ganzheitliches Modell vorgezeigt werden, sondern lediglich der entwickelte, leicht erweiterbare Ansatz zur ökonomischen Bewertung präsentiert werden. Dank dieses Modells konnten bereits wertvolle Erkenntnisse zur Systemoptimierung erlangt werden und Anknüpfungspunkte für weitere Bewertungsmöglichkeiten definiert werden.
