Green development of Greater Kuala Lumpur, the urban

Green development in architecture can provide environmental benefits in urban cities. One of the green development is to apply green wall on the tall building which always have large building surface exposed. Tall building provide many surfaces for the reflection and absorption of sunlight give impact on environmental issue. Tall building also block more wind than shorter ones, leading to less natural cooling. The absent of natural ventilation leads to heavy reliance on air conditioning, producing significant amounts of waste heat. “Due to the increased development of Greater Kuala Lumpur, the urban heat island or hot areas are growing,” climate expert Prof Datuk Dr Azizan Abu Samah (University Malaya) said. Dr Azizan also mentioned that green- areas in cities should be protected to help reduce the urban heat island effect.

In facts, urban heat island (UHI) effect the tendency for metropolitan areas to be several degrees warmer than their surrounding suburbs. UHI are often seen in urban area due to fast urbanization development, it is cause by nature of man-made surfaces in cities buildings created large wall surface, paved areas, and dark roofs absorb far more sunlight and reemit more heat than natural vegetation.

Therefore a soil and vegetation layer facade is the solution to introduce in Kuala Lumpur city.

1.2 Objective

The objective of this study presented is to investigate the impact of greenery façade on UHI caused by tall buildings in Kuala Lumpur. By doing a comparison study on the different between constructing conventional wall with bare facade and a green wall façade on tall building in term of reduce outdoor exclusive heat caused by tall building. The purpose of this research is to investigate the feasibility and plausibility of the vertical green wall concept from resources data collect from literatures wrote by researchers in specific and interrelated research domains. The research domain is to find out the way to cool down external of a building heat. Solution Green façade possible uptake of the technology. In the rest of this paper, the (1) literature review, (2) analysis and discussion of results, (3) suggestion and recommendation, and (4) conclusion will be presented.

 

1.3 Research Question: Installing the building external green facade to enhance comfort outdoor environment to the users in Kuala Lumpur.
