Buildings are responsible for: 76% of total U.S. electricity consumption >60% of total U.S. primary energy use 30% of total U.S. greenhouse gas emissions 136 million tons of construction & demolition waste in U.S. [approx. 2.8 lbs/person/day] 12% of potable water in U.S. 40% [3 billion tons annually] of raw material use globally *commercial and residential why green
What is Sustainable Design ? Design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment and occupants in five broad areas: :: Sustainable site planning :: Safeguarding water and water efficiency :: Energy efficiency and renewable energy :: Conservation of materials and resources :: Indoor environmental quality Benefits of Green Buildings Environmental Benefits :: Reduce the impacts of natural resource consumption Economic Benefits :: Reduce Operating Costs Health and Safety Benefits :: Enhance occupant comfort and health Community Benefits :: Improve quality of educational experience why green
LEED (Leadership in Energy and Environmental Design) - internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings water efficiency CO2 emissions reduction improved indoor environmental quality stewardship of resources and sensitivity to their impacts Developed by the US Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. LEED is flexible enough to apply to all building types – commercial as well as residential. It works throughout the building lifecycle – design and construction, operations and maintenance, tenant fit-out, and significant retrofit. And LEED for Neighborhood Development extends the benefits of LEED beyond the building footprint into the neighborhood it serves. What is LEED ?
