“…A state-of-the-art work on the use of FMEA in building construction was prepared by Talon et al (2006) in which several examples on the use of FMEA are presented, and in Talon (2006), the FMEA for an insulated brick cavity wall is presented. According to Mao et al (2011), moisture is the most crucial factor causing deterioration of the building envelope.…”

The preponderant number of multi-story buildings constructed in Denmark (Northern Europe) in the period between 1850-1930 were built with masonry walls incorporating wooden floor beams. Given the nature of this construction, it is supposed that significant energy savings could be achieved by simply insulating the facades of such buildings. To maintain the exterior appearance of the facade the only possible means of installing the required insulation is placing it on the interior of the wall. However, the installation of insulation on the interior of the wall assembly reduces the overall drying potential of the wall, and this in turn may lead to moisture problems at the beam ends embedded in the masonry, when the masonry facade is subjected to driving rain. This paper presents a method to investigate retrofit measures of interior insulated masonry walls having wooden floor beams based on Failure Mode and Effect Analysis combined with hygrothermal simulations. The method was first used to determine the potential for failure in retrofitted walls, their effects and causes, and thereafter, the expected hygrothermal performance of the retrofit measures were further investigated using both thermal and hygrothermal simulation software. The results show that the risk to incurring moisture problems at wooden beam ends can be resolve by not insulating that portion of the wall directly above and below the floor division.Additionally, this proposed retrofit measure would reduce the heat loss of the original wall structure by half.

“…The context of the building domain, as detailed in Talon (2006b), implies some difficulties to obtain the assessment of long-term performances of building components in-service. Indeed: (i) there are numerous types of building components and numerous building actors who influence design and implementation qualities; (ii) building components are subjected to random environment and have to ensure several performance requirements; (iii) instrumentation of a large sample of building component could allow service life to be assessed but should be economically unrealistic.…”

“…The system analysis and the FMEA of this specific window unit were undertaken together with a selected group of experts in materials and insulated glass units for which a significant list of degradation scenarios were developed as detailed in Talon (2006b). The emphasis here is not placed on the results of the FMEA but on the way to assess the window service life based on the knowledge of the degradation scenarios and also based on the availability of service life data.…”

Service-life assessment of building components: application of evidence theory

This paper deals with the assessment of the service life of in-service building components subjected to known environmental and usage conditions. This assessment is complex because of two primary features. First, the assessment has to be carried within a multiscale context: a geometric scale that ranges from the material or elemental to building scale; a range in the complexity of the degradation (phenomena that varies from a single phenomenon to the consideration of several degradation scenarios); a range of possible performance requirements, from one function to several; and consideration, as well, to the time over which the process is carried out that may span from the design stage to that of management and repair. Second, this assessment must also take into consideration the availability and features of service-life data that by nature is heterogeneous, imprecise, uncertain, and incomplete. In this context, a comprehensive methodology is developed using all available data on service life derived from existing methods of service-life assessment of materials, elements or building components. Such data may, for example, be extracted from fundamental studies on durability, accelerated short-term exposure tests, statistical methods, factorial methods, feedback from practice, or expert opinion or other sources. The main stages of this methodology are: (i) identification of all possible degradation scenarios provided by failure mode and effects analysis (FMEA); (ii) collection of all available service-life data (SL-data) associated with these degradation scenarios, transformation of this data into a fuzzy-set format, and assessment of its quality; (iii) processing of unification of data and aggregation of data; and (iv) assessment of the service life of building components. The case study of a window unit allows for: (i) service-life assessment of a building component to be processed by unification of data and aggregation of data and (ii) a conclusion to be deduced.
