scope:

This Technical Specification is a framework document that provides the general principles and requirements for development of the methodologies, expressed through a suite of standards, for the assessment of aspects of sustainability of buildings in terms of environmental performance, health and comfort performance and life cycle cost performance taking into account the technical description and functionality of a building.
The framework applies to all types of buildings, both new and existing, and it is relevant for the assessment of the performance of new buildings over their entire life cycle, and of existing buildings undergoing refurbishment, renewal or extension, to the end of their life.
The framework defines the boundaries for the assessment, provides the assessment categories and describes how the assessment results are to be treated and communicated.
The environmental dimension of sustainability is limited to the assessment of environmental impacts of a building on local, regional and global environment on the basis of Life Cycle Assessment expressed with the quantitative assessment categories. It excludes the environmental risk assessment of a building on the local environment and it excludes environmental aspects of a building relating to the built environment that extend beyond the area of the building site, e.g. environmental impacts of construction of local infrastructure or environmental impacts resulting from transportation of the users of the building. Other means for measurement of environmental performance of buildings, which are not based on the Life Cycle Assessment methodology, are not considered within this framework.
The social dimension of sustainability is limited to the assessment of health and comfort impacts of a building to its occupants and other users expressed with the quantitative assessment categories. It excludes health and safety aspects related to construction workers. It also excludes the social aspects of a building relati
