GreenBuildings.com recently released the 2009 Green Building Market & Impact Report, which examines Leadership in Energy and Environmental Design (LEED®)-certified buildings' effects on energy, water, waste and employee productivity, according to www.greenerdesign.com. The report also projects the effects for the next 20 years.

Some of the report's highlights include:
  • An estimated 15 billion gallons of total water savings from LEED during 2009, which is about 0.5 percent of annual nonresidential water use. The report projects that by 2030, almost 1.3 trillion gallons of water will be saved by LEED, which is about 30 percent of current annual nonresidential water use.

  • The estimate of reduced vehicle miles traveled has increased from 400 million in 2008 to 780 million in 2009. By 2030, annual gas savings are expected to be equivalent to current U.S. imports from the Middle East.

  • Green building materials represented about $7 billion in cumulative spending during 2009; that number is expected to reach $230 billion by 2030.

  • An average of more than 60 percent of construction and demolition waste was diverted from LEED projects, totaling about 25 million tons.

  • Annual carbon dioxide savings from LEED-certified buildings is about 2.9 million tons, which is expected to reach 130 million tons by 2020 and 320 million tons by 2030.

  • Productivity benefits from LEED buildings currently range from $230 million to $450 million.

  • The green building work force is expected to reach 29 million by 2020 and almost 64 million by 2030.

  • Floor area registered and certified by LEED in 2009 is estimated to increase by more than 40 percent compared with 2008, reaching a total of 7 billion square feet worldwide since LEED launched in 2000.
