1、Designation: E 2432 05Standard Guide forGeneral Principles of Sustainability Relative to Buildings1This standard is issued under the fixed designation E 2432; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisio
2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 Sustainabilty has three types of general principles:environmental, economic, and social. This guide covers thefundamental concept
3、s and associated building characteristicsfor each of the general principles of sustainability.1.2 This guide distinguishes between ideal sustainabilityand applied sustainability. Ideally, human activities would notrequire making trade-offs among environmental, economic,and social goals. However, thi
4、s guide recognizes that, inapplying sustainability principles to buildings, decision makersmust often balance opportunities and challenges associatedwith each of the general principles.1.3 This guide identifies general methodologies associatedwith the decision-making process used in pursuing sustain

6、se.1.4.2 The general principles identified in this guide areapplicable to all life-cycle stages of a building and its compo-nents, including: material extraction, product manufacturing,product transportation, planning, siting, design, specification,construction, operation, maintenance, renovation, r
7、etrofit, re-use, deconstruction, and waste disposal of buildings.1.5 A variety of tools and standards exist that qualify andquantify impacts of buildings, building materials, and buildingmethods in terms of one or more of the general principles ofsustainability. It is not within the scope of this st
8、andard torecreate or replace these tools.1.6 This guide does not provide direction as to the specificimplementation of the general principles; nor does it providedirection as to the specific weighting of principles necessaryfor achieving balance.1.7 Implementation of this guide will require professi

These impacts occur at alllife-cycle stages in multiple ways and on local, regional, andglobal scales. It
34、 is imperative to understand the nature of theseimpacts and their relationship to the general principles ofsustainability in order to address the opportunities and chal-lenges they present in buildings.4.1.1 Buildings impact the environment. In order to advancesustainability, it is necessary to iden
35、tify environmental impacts,mitigate negative environmental impacts, and promote positiveenvironmental impacts.E24320524.1.2 Buildings have economic impacts. In order to advancesustainability, it is necessary to quantify and optimize life-cycle costs/benefits and external costs/benefits to the greate
36、stextent possible.4.1.3 Buildings impact society. In order to advance sustain-ability, it is necessary to identify the health, safety, and welfareimpacts, and to contribute to a positive quality of life forcurrent and future generations.4.2 The general principles of sustainabilityenvironmental, econ
37、omic, and socialare interrelated. Deci-sions founded on the opportunities and challenges of any of theprinciples will have impacts relative to all of the principles.However, to facilitate clarity in the presentation of the generalprinciples of sustainability relative to buildings, they arediscussed
38、individually in Section 5.4.3 Sustainability is an ideal. The practical application ofthe general principles of sustainability relies upon balancingenvironmental, economic, and social impacts and committingto continual improvement to approach this ideal. Section 6discusses this balancing of environm
39、ental, economic, andsocial impacts in pursuit of sustainability.4.4 The marketplace is evolving as technology, economics,and society become globalized. The range of topics andapproaches to standards development has evolved in tandemwith the changes in the marketplace. This guide addresses oneof the
40、primary issues of todays global marketplacesustainability. It provides an overview of sustainability, as it isapplicable to buildings. It provides general guidance but doesnot prescribe a specific course of action.4.5 This guide is intended to inform professionals associ-ated with the building indus
41、try, including specifiers, planners,developers, architects, landscapers, engineers, general contrac-tors, subcontractors, owners, facility managers, financial orga-nizations related to the building industry, product manufactur-ers, and government agencies including building officials, andother build
42、ing professionals.4.5.1 The general principles identified in this guide areintended to assist users in making decisions that advancesustainability.4.5.2 The general principles identified in this guide areintended to inform the development and refinement of toolsand standards to qualify and quantify
43、impacts of buildings,building materials, and building methods.5. Principles of Ideal Sustainability Relative to Buildings5.1 Environmental PrinciplesBuildings impact the envi-ronment. From gathering raw materials, production of compo-nents, assembly into structures, day-to-day operations, periodicma
44、intenance, to the final disposition of the components, thereare impacts on the environment. Environmental impacts affectecosystems, biodiversity, and natural resources. In order toadvance sustainability, it is necessary to identify environmentalimpacts, mitigate negative environmental impacts, and p
45、ro-mote positive environmental impacts.5.1.1 Fundamental Concepts:5.1.1.1 EcosystemsEcosystems provide critical servicesthat support life on the earth and the continued viability of alarge range of flora and fauna. Sustainability protects existingecosystems and strives to restore damaged ecosystems.
46、5.1.1.2 BiodiversityBiodiversity provides environmentaloptions, both known and unknown, that contribute to thegenetic resilience of the earths flora and fauna. Sustainabilityprotects or enhances the biodiversity and interdependencies ofspecies.5.1.1.3 Natural ResourcesNatural resources provide theba
47、sic requirements of life and the material/energy from whichall human-made material/energy is derived. Sustainabilitybalances the use of earths renewable, non-renewable, andperpetual resources in order to preserve these resources forfuture generations.5.1.2 Associated Building Characteristics:5.1.2.1
48、 EcosystemsSustainable buildings contain featuresthat protect or enhance local, regional, and global ecosystems.For example, energy efficiency features, both active andpassive, can reduce the amount of energy used by the building.This approach can reduce the regional impacts associated withair emiss
49、ions from electric power generation facilities andreduce the local impacts of the heat island effect.5.1.2.2 BiodiversitySustainable buildings contain featuresthat protect or enhance species habitats. For example, a greenroof system can retain and utilize stormwater through the useof climate-appropriate plants. This approach can reduce theamount of polluted stormwater runoff and creates new habitatswithin the built environment.5.1.2.3 Natural ResourcesSustainable buildings maxi-mize the effective use of resources.
