Understanding Green Building Practices
Exploring green building practices unveils a modern approach towards creating structures that are not only beneficial for humans but also for the environment. These practices emphasise sustainability and environmental protection, embedding them into the very fabric of construction and building management.
What Are Green Building Practices?
Green Building Practices refer to the planning, design, construction, operation, and maintenance of buildings with key considerations for energy use, water use, indoor environmental quality, material selection and the building's effects on its surroundings.
