How Green Walls Help Reduce Heat & Energy Consumption in Malaysia
As Malaysia continues its rapid urbanisation and development, increasing concerns over energy consumption, rising temperatures and environmental sustainability have emerged. Cities such as Kuala Lumpur, Johor Bahru and Penang are experiencing intensified urban heat island effects, where built‑up areas become significantly hotter than their rural surroundings. One sustainable solution gaining traction to combat heat and reduce energy usage is the implementation of green walls — vertical gardens attached to building exteriors and interiors. In the Malaysian context, green walls not only provide aesthetic value but also deliver measurable benefits in cooling and energy efficiency.
Understanding Green Walls
Green walls, also known as vertical gardens or living walls, consist of plants grown on structures mounted to walls. These systems can be hydroponic (soil‑free) or soil‑based and often include irrigation and fertilisation systems. In tropical Malaysia — where temperatures average 27°C to 32°C throughout the year — green walls offer a natural …
