Building construction accounts for nearly half of all copper use. Residential construction is about two-thirds of the building construction market.
The following figures are based on a single-family home of about 2,100 sq.ft. and a multifamily unit of about 1,000 sq.ft.
An average single-family home uses 439 pounds of copper.
In an average single-family home, you will find about:
195 pounds - building wire
151 pounds - plumbing tube, fittings, valves

10 pounds - other wire and tube
An average multifamily unit uses 278 pounds of copper:

82 pounds - plumbing tube, fittings, valves
20 pounds - plumbers' brass goods
38 pounds - built-in appliances
