The new ISO 21931-1:2010 standard is aimed at improving the environmental performance of buildings by providing an internationally agreed framework for methods used in assessing their environmental stewardship.
Over their life cycle, buildings absorb considerable resources and contribute to the transformation of the environment. As a result, they can have considerable consequences and impacts on the environment. In order to measure and understand this impact, methods of assessment are used to determine the environmental performance of buildings and their related external works.
