This document specifies requirements for, and gives guidance on, the application of life cycle costing for the development activities and operations associated with drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers facilities and associated activities within different business categories (upstream, midstream, downstream and petrochemical).

The life cycle costing process as described in this document is applicable when making decisions between competing options that are differentiated by cost and/or economic value implications. This document is not concerned with decision making related to the economic performance of individual options or options differentiated by factors other than cost or economic value.

Guidance is provided on the management methodology and application of life cycle costing in support of decision making across life cycle phases. The extent of planning and management depends on the magnitude of the costs involved, the potential value that can be created and the life cycle phase. It also provides the means of identifying cost drivers and provides a cost-control framework for these cost drivers, allowing effective cost control and optimization over the entire life of an asset.

This document provides principles and requirements for the assessment of environmental, social and economic performance of buildings and civil engineering works taking into account their technical characteristics and functionality. Assessments of environmental, social and economic performance are the three aspects of sustainability assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction works”).
The framework applies to all types of construction works, both new and existing, and it is relevant for the assessment of the environmental, social and economic performance of new construction works over their entire life cycle, and of existing construction works over their remaining service life and end of life stage.
The sustainability assessment of construction works concentrates on the assessment of environmental, social and economic aspects and impacts of construction works expressed with quantifiable indicators. It includes the assessment of a construction works’ influence on the environmental, social and economic aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the curtilage of the building and the civil engineering works. It excludes environmental, social and economic risk assessment.
The European Standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods; nor do they prescribe levels orclasses for measuring performance.
NOTE Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for environmental, social and economic performance in the client’s brief, construction regulations, national standards, national codes of practice, construction works assessment and certification schemes, etc.
The rules for assessment of environmental, social and economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the environmental, social and economic performance of the object of assessment are taken into account.
