A typical North American Commercial construction project generates up to 2.5 pounds of solid waste per square foot of completed floor space.
Construction and demolition wastes constitute about 40% total solid waste stream in the U.S.
20% of America goes to school every day. Far too often our nation's schools are only built to code and we send our children to spend six hours a day to facilitites that just barely meet health and safety standards.
Vehicles are responsible for approximately 20% of U.S. greenhouse gas emissions annually. (NRDC)
Americans spend on average 90% of their times indoors where the U.S. Environmental Protection Agency reports that levels of pollutants may run two to five times higher than outdoor levels.
Each day five billion gallons of potable water is used to flush toilets.
Regional recycling facitlities accepting comminged waste are achieving waste diversion rates of 80% or greater in many areas.
On average, according to Capital E's "Greening America's Schools" study, green schools use 30-50% less energy ad 30% less water.
If a green school saved $100,000 per year in operation costs, that's roughly enough to hire two new teachers, buy 200 neww computers or purchase 5000 new textbooks.
In the U.S. approximately 340 billion gallons of fresh water are withdrawn per day from rivers, streams and reserviors to support residential, commercial, industrial, agricultural and recreational activities.
Buildings annually consume more than 30% of the total energy and more than 60% of the electricity used in the U.S.
In a case study included in the 1994 publication "Greening the Building and the Bottom Line," the Rocky Mountain Institute cites how improved indoor environmental quality improved worker productivity by 16%, netting a rapid payback on the increased capital investment.
