The revised European Standard will specify calculation methods, based on Life Cycle Costing (LCC) and other quantified economic information, to assess the economic performance of a building, and will provide requirements for reporting, communication and documentation of assumptions to support transparent and comparable application in practice.
The revised European Standard will remain applicable to new and existing buildings and refurbishment projects, and will maintain alignment with the TC 350 modular life-cycle structure and scenario-based approach across all life-cycle stages at building level.
The revision will include:
• an updated description of the object of assessment, including clarification of functional equivalence and reference study period;
• the system boundary at building level and the principles for consistent scenario definition across life-cycle modules (including replacement modelling and end-of-life pathways);
• the scope and procedure for the economic assessment, including parameterisation (e.g. discounting, escalation where relevant, and treatment of uncertainty/sensitivity as appropriate);
• the indicators and calculation procedures, including Life Cycle Costing as the mandatory indicator and Life Cycle Economic Balance as an optional indicator;
• clarified rules for documenting and reporting costs and, where applicable, incomes/negative costs, including exported energy and potential income streams related to reuse, recycling and recovery beyond the system boundary (Module D), ensuring consistency with scenarios in other life-cycle modules;
• requirements for presentation of results in reporting and communication, aiming to enhance usability for decision support and, where relevant, procurement contexts through consistent and auditable reporting;
• requirements for input data and data quality, including documentation of sources and key assumptions (e.g. service lives, replacement profiles, maintenance regimes, energy/water cost assumptions, and end-of-life scenarios).
The approach will continue to cover all stages of the building life cycle and include all building-related construction products, processes and services used over the life cycle. The interpretation of results and value judgements derived from the assessment remain outside the scope of this European Standard.
