Copper Facts
Copper In The Home
Building construction accounts for more than 40% of all copper use. Residential construction is about two-thirds of the building construction market. The average single-family home is about 2,100 sq .ft.; a multifamily unit averages 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, fillings, valves
24 pounds - plumbers' brass goods
47 pounds - built-in appliances
12 pounds - builders hardware
10 pounds - other wire and tube - An average multifamily unit uses 278 pounds of copper:
125 pounds - building wire
82 pounds - plumbing tube, fittings, valves
20 pounds - plumbers' brass goods
38 pounds - built-in appliances
6 pounds - builders hardware
7 pounds - other wire and tube - General levels of copper use in major appliances:
52 pounds - unitary air conditioner
48 pounds - unitary heat pump
5.0 pounds - dishwasher
4.8 pounds - refrigerator/freezer
4.4 pounds - clothes washer
2.7 pounds - dehumidifier
2.3 pounds - disposer
