Leadership in Energy and Environmental Design (LEED) standards make up a rating
system based on standards created by the United States Green Building Council USGBC(United States Green Building Coalition), a non-profit organization dedicated towards building a
greener environment). These LEED standards have been created to evaluate how a buildingperforms in terms of its impact on the environment. Criteria used to evaluate a building includesustainable construction, water efficiency, energy use and emissions, indoor environmentalquality, and location. Structures that meet these criteria are referred to as green buildings.Various measures can be taken, for both new construction and the renovation of existingstructures, to improve their LEED ratings.
LEED:
LEED rating systems represent international standards of certification that recognizeenvironmentally sustainable design, construction, operation, and maintenance of residential andcommercial buildings.LEED rating systems provide four certification levels for the environmental sustainabilityof the sites they measure:
� Certified� Silver � Gold� Platinum.These relate to the building ratings in the following categories:� Materials and resources� energy and atmosphere� sustainability
� water efficiency� indoor environmental quality.
LEED Rating Systems:
� Innovation and design.

LEED rating systems allow buildings to lower operational costs while potentially increasingasset value. This help reduce waste and increase conservation of energy and water. These
sites can provide more healthful and safe interaction with their human occupants.

LEED Cr edits:
(LEED) credits are a series of qualifications that were devised to rate the effectiveness
of green building.The LEED credits are given according to a 100 point scale. There are also additionalbonus points available in increments of 10, primarily for special regionalconsiderations.For the entity to r eceive cer tification, it must r eceive at least 26 points.There are several levels of certification, the attainment of which depends on thenumber of LEED credits given.� The basic certification level is from 26 to 32 points.
� In order to achieve the middle levels ² silver and gold ² the entity must receive33 to 38 and 39 to 51 points respectively.
� The top level is platinum which requires a minimum of 52 points.
And these credits are given according to the six categories mentioned before dealingby the LEED checklist.
