  2. More Housing Needed • In 2002, California had approximately 12.4 million housing units. • Between 1997 and 2020, approximately 5 million new households will be formed. • To meet that new housing demand approximately 220,000 housing units will need to be built annually between now and 2020. Source: California Department of Housing and Community Development

  3. Housing Production • Average valuation of new homes of all types for the five-year period of 1997-2001 was $20.3 billion per year • 167,761 housing permits were issued in 2002. • 123,865 single-family • 43,896 multi-family.

  4. Housing Facts • Of the units existing in 2000, 87% were built before 1990 and 70% were built before 1980 • The average area of a new house in 2002 was 2,350 ft2, up nearly 9 percent from 2160 ft2 in 1990 (western region of the US)

  5. Environmental Impacts • In 2000, the CA Residential sector consumed 80,615 million kWh of electricity, roughly 31% of the total. • In 2000, total applied Urban Residential water use was 5.6 million-acre feet (MAF), • Interior Use 3.3 MAF, 59% Residential use • Exterior Use, 2.3 MAF, 41% of Residential use

  6. Material Impacts • Average solid waste generated during the construction of a 2,000 ft2 home is nearly 3.5 tons1 • Average solid waste generated is estimated at 4.38-lbs/sq ft.2 • Waste generated during construction of a 2,350 ft2 house is about 5 tons Sources: 1.

  14. SBTF: Green Residential Action Program (GREAT) Vision achieved through… • Collaboration   • Guidelines • Incentives  • Recognition • Research  • Education
