Urban Village Regeneration: Improved Outdoor Thermal Comfort Using a Productive Facade

The urban village's vernacular physical landscape and social problems were associated with the right to enjoy high physical and mental health standards and adequate food. The environmental conditions of urban kampong today are precarious due to high-density buildings and limited green space. The Productive Facade (PF), as a form of the Vertical Greenery System, is an approach to developing green space in limited space, considering that green space has the potential to drive urban regeneration and development. This research aims to evaluate whether PF could improve outdoor thermal comfort (OTC) and its impact on the rights of those affected by conducting actual climate tests using building models in an open field. The PF was placed in an east and west orientation using the pumpkin and sweet potato plant. We recorded the diurnal air temperature, humidity, wind velocity, and solar radiation to evaluate the wet bulk globe temperature (WBGT) and the thermal humidity index (THI). This research found that PF positively reduced both the WBGT and THI values and the duration of exposure to the high value of WBGT and THI on the west and east sides. It concludes that PF is a promising urban regeneration strategy through green space access, improved microclimate of urban villages, enhanced social cohesion, and food provision.
