Please correct me Environmental sustainability of a building When constructing the building it was highly cost. But reusing the building is a different thing. It’s reduce the construction energy rather than demolish old building. Energy used for construct the old building is also useful for the new purpose. Most adaptive reuse projects are low cost than a building new one. Because it’s save the materials and the construction energy lot. Adaptive reuse is a good option to reduce the cost of energy for a project.
