The composition of the committee was diversenull it included architects, real estate agents, a building owner, a law
13、yer, an environmentalist, and industry representatives. This cross section of people and professions added a richness and depth both to the process and to the ultimate product.

21、c.org.Features of leeDThe LEED nulleen Building nullating nullstems are voluntary, consensusnullased, and marketnullriven. Based on existing and proven technology, they evaluate environmental performance from a wholenullbuilding perspective over a buildingnull life cycle, providing a definitive stan
22、dard for what constitutes a green building in design, construction, and operation. The LEED rating systems are designed for rating new and existing commercial, institutional, and residential buildings. They are based on accepted energy and environmental principles and strike a balance between known,
23、 established practices and emerging concepts. Each rating system is organized into null environmental categoriesnull nullstainable nulltes, nullater Efficiency, Energy and nullmosphere, nullaterials and nullesources, and nullndoor Environmental nulluality. null additional category, nullnnovation in
24、Design, addresses sustainable building expertise as well as design measures not covered under the nullenvironmental categories. nullegional bonus points are another feature of LEED and acknowledge the importance of local conditions in determining best environmental design and construction practices.
25、the leeD Credit weightingsnulln LEED nullnull, the allocation of points between credits is based on the potential environmental impacts and human benefits of each credit with respect to a set of impact categories. The impacts are defined as the environmental or human effect of the design, constructi
26、on, operation, and maintenance of the building, such as greenhouse gas emissions, fossil fuel use, toxins and carcinogens, air and water pollutants, indoor environmental conditions. nullcombination of approaches, including energy modeling, lifenullycle assessment, and transportation analysis, is use
27、d to nullantify each type of impact. The resulting allocation of points among credits is called credit weighting.LEED nullnull uses the null.null Environmental nullrotection nullencynull Tnullnullnullenvironmental impact categories as the basis for weighting each credit. Tnullnull was developed to a
28、ssist with impact evaluation for lifenullycle assessment, industrial ecology, process design, and pollution prevention. xiiiLEED REfEREncE GuiDE foR GREEn intERioR DEsiGn anD constRuction2009 EDitionLEED nullnull also takes into consideration the weightings developed by the nullational nullnstitute
29、of nullandards and Technology nullnullTnull these compare impact categories with one another and assign a relative weight to each. Together, the nullapproaches provide a solid foundation for determining the point value of each credit in LEED nullnull. The LEED nullnull credit weightings process is b

32、 criteria, the LEED nullnull credit weightings process involves nullstepsnullnull nullreference building is used to estimate the environmental impacts in null categories associated with a typical building pursuing LEED certification.null The relative importance of building impacts in each category a
33、re set to reflect values based on the nullnull weightings.nullnull Data that nullantify building impacts on environmental and human health are used to assign points to individual credits. Each credit is allocated points based on the relative importance of the buildingnullelated impacts that it addre
34、sses. The result is a weighted average that combines building impacts and the relative value of the impact categories. nulledits that most directly address the most important impacts are given the greatest weight, subnullct to the system design parameters described above. nulledit weights also refle
35、ct a decision by LEED to recognize the market implications of point allocation. The result is a significant change in allocation of points compared with previous LEED rating systems. nullverall, the changes increase the relative emphasis on the reduction of energy consumption and greenhouse gas emis
36、sions associated with building systems, transportation, the embodied energy of water, the embodied energy of materials, and where applicable, solid waste. The details of the weightings process vary slightly among individual rating systems. nullor example, LEED for Existing Buildingsnullnullnullinclu
37、des credits related to solid waste management but LEED for nullew nullnstruction does not. This results in a difference in the portion of the environmental footprint addressed by each rating system and the relative allocation of points. The weightings process for each rating system is fully document
38、ed in a weightings workbook. The credit weightings process will be reevaluated over time to incorporate changes in values ascribed to different building impacts and building types, based on both market reality and evolving scientific knowledge related to buildings. nullcomplete explanation of the LE
