CEN/TC 350/WG 4 - Economic performance assessment of buildings

This European Standard specifies the calculation methods, based on Life Cycle Costing (LCC) and other quantified economic information, to assess the economic performance of a building, and gives the means for the reporting and communication of the outcome of the assessment. This European Standard is applicable to new and existing buildings and refurbishment projects.
This European Standard gives:
-   the description of the object of assessment;
-   the system boundary that applies at the building level;
-   the scope and procedure to be used for the analysis;
-   the list of indicators and procedures for the calculations of these indicators;
-   the requirements for presentation of the results in reporting and communication;
-   and the requirements for the data necessary for the calculation.
The approach to the assessment covers all stages of the building life cycle and includes all building related construction products, processes and services, used over the life cycle of the building.
The interpretation and value judgments of the results of the assessment are not within the scope of this European Standard.

This European Standard forms one part of a series of European Standards for the assessment of buildings and provides specific principles and requirements for the assessment of economic performance of buildings taking into account technical characteristics and functionality of a building. Assessment of economical performance is one aspect of sustainability assessment of buildings under the general framework of EN 15643-1.
The framework applies to all types of buildings and it is relevant for the assessment of the economic performance of new buildings over their life cycle, and of existing buildings over their remaining service life and end of life stage.
The economic performance assessment of a building addresses the life cycle costs and other economic aspects, all expressed through quantitative indicators. It excludes the economic risk assessment of a building and return on investment calculations
It includes economic aspects of a building relating to the built environment within the area of the building site, it does not include economic aspects beyond the area of the building site, e.g. such as economic impacts of construction of local infrastructure or economic impacts resulting from transportation of the users of the building or economic impacts of a construction project on local community.
The 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, classes or benchmarks for measuring performance.
NOTE   Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for economic performance in the client’s brief, building regulations, national standards, national codes of practice, building assessment and certification schemes, etc.
The rules for assessment of economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the economic performance of the object of assessment are taken into account.
