As a durable and sustainable metal with a long service life and full recyclability, copper plays a crucial role in the heating and cooling, plumbing, wiring, lighting and roofing of buildings. When it comes to making buildings more ‘green’ – i.e. with design, construction and operation that minimises negative impacts on the environment, or even offers positive contributions - key components such as energy efficiency and smarter resource usage depend on copper. The greener the building, the more copper is needed.
