LEED: Leadership in Energy and Environmental Design
The U.S. Green Building Council (USGBC) is a nonprofit organization committed to the sustainable future for our built environment through cost-efficient and energy-saving buildings.
The LEED green building certification program is a national rating system for buildings designed, constructed and operated for improved environmental and human health performance. LEED promotes green building strategies in five areas: sustainable site development, water savings, energy efficiency, materials and resources selection, indoor environmental quality, and innovation & design process.
The rating system has four levels of certification defined by a point system based on a system of green building requirements. There are 69 possible points of green building features, in addition to pre-requisites required. The levels of certification are as follows:
Certified: 23-27 points
Silver: 28-33 points
Gold: 34-44 points
Platinum: 45-61 points.
Statistics:
In the United States alone, buildings account for:
72% of electricity consumption,
39% of energy use,
38% of all carbon dioxide (CO2) emissions,
40% of raw materials use,
30% of waste output (136 million tons annually), and
14% of potable water consumption.
Benefits of Green Building:
Environmental benefits:
Enhance and protect ecosystems and biodiversity
Improve air and water quality
Reduce solid waste
Conserve natural resources
Economic benefits:
Reduce operating costs
Enhance asset value and profits
Improve employee productivity and satisfaction
Optimize life-cycle economic performance
Health and community benefits:
Improve air, thermal, and acoustic environments
Enhance occupant comfort and health
Minimize strain on local infrastructure
Contribute to overall quality of life
