VERTICAL GREENING SYSTEM FOR ENVIRONMENT RESPONSIVE ARCHITECTURE : the Case of Multistory Residential Buildings in Addis Ababa

Vertical greening systems can help mitigate the urban heat islands, increase the thermal efficiency of the buildings, save cooling energy and enhance air quality by using the vegetation's natural processes. However, since vertical greening schemes need materials and energy to be built, there are questions about whether they actually deserve to be adopted and how their environmental efficiency can be improved. The study aims to evaluate verticalgreening systems' environmental efficiency and to study essential factors for efficient and sustainable building construction.
