Yes indeed, Green building is not always a sustainable building. Saya sangat menyokong hujah tuan.
Green building is more to the use of renewable energy sources such as wind, water, or solar in creating a healthy building environment by minimizing the mechanical and electrical use to reduce the impact on the natural environment.
Sustainable building is more to the use of renewable building material sources naturally by using construction method or techniques that can protect the environment and overall community to sustain the supplies for future generation.
Therefore, a green building is not always a sustainable building.
Only building that meets zero energy standards with zero net energy consumption and zero carbon emissions can be considered sustainable. Buildings that contribute to urban sprawl that consume high energy and resources can not be considered as sustainable.
