DIN EN 15331:2011-11

A building presents a challenging set of maintenance-related requirements which, although not unique, are not often found together: - the need to maintain property value of the building over time; - the possibility that the property may undergo a significant change in its intended use during its service life; - the number of persons responsible for maintenance and the different type of responsibility (owner, administrator, tenant, user, ...); - its long service life (decades). Under these conditions, it is difficult to predict with any degree of precision the service life of each component. Budgeting for maintenance, and specifically the scheduling of maintenance interventions, requires the availability and the analysis of feedback data obtained from maintenance activities. The purpose of building maintenance is to ensure utilisation of the asset by maintaining its value and initial performance within acceptable limits for its whole service life, as well as promoting technical and regulatory modifications to initial or new technical requirements as selected by the operator or demanded by law. To achieve this goal, a definition of general criteria to collect data that is essential for maintenance activities and the use of suitable information systems may be used to develop database and management tools to improve the profitability of buildings. DIN EN 15331 specifies the criteria and the general methods that can be used in the planning, management and control of maintenance in buildings and their surrounding area according to the applicable legal requirements, objectives of the owners and users and the required quality of maintenance. The European document (DIN EN 15331:2011) has been prepared by CEN/TC 319 "Maintenance". On the national level, the Committee responsible for the preparation of this standard is Working Committee NA 152-06-07 AA "Instandhaltung" ("Maintenance") of the Fundamental Technical Standards Committee (NATG). DIN EN 15331 supersedes DIN CEN/TS 15331:2006-02.
