Description of PD ISO/TS 21929-2:2015 2015

This part of ISO 21929 establishes a list of aspects and impacts which should be taken as the basis for the development of sustainability indicators for assessing the sustainability performance of new or existing civil engineering works, related to their design, construction, operation, maintenance, refurbishment and end-of-life. Together, the indicators developed from this list of aspects and impacts provide measures to express the contribution of a civil engineering works to sustainability and sustainable development. The developed indicators should represent aspects of civil engineering works that impact on issues of concern related to sustainability and sustainable development.

The object of consideration in this part of ISO 21929 is a civil engineering works, a part of the civil engineering works or a combination of several civil engineering works.

NOTE The aspects and impacts described in this part of ISO 21929 are intended to be used for all types of civil engineering works. Development of specific sets of indicators for different typologies of civil engineering works (industrial processes infrastructures; linear infrastructures; dams and other fluvial works; maritime works; public spaces; other civil engineering works-not contained in the previous typologies) will be the subject of future standardization work.

This part of ISO 21929

• adapts general sustainability principles for civil engineering works,

• includes a framework for developing sustainability indicators for use in the assessment of economic, environmental and social impacts of civil engineering works,

• establishes a core set of aspects and impacts, which should be taken into account, when developing systems of indicators for civil engineering works,

• describes how to use sustainability indicators with regard to civil engineering works, and

• gives rules for establishing a system of indicators.

This part of ISO 21929 follows the principles set out in ISO 15392 and, where appropriate, is intended to be used in conjunction with, and following the principles set out in, ISO 26000, ISO 14040 and the family of International Standards that includes ISO 14020, ISO 14021, ISO 14024 and ISO 14025. Where deviation occurs or where more specific requirements are stated, this part of ISO 21929 takes precedence.

This part of ISO 21929 does not give guidelines for the weighting of indicators or the aggregation of assessment results.
