Influence of Climate Conditions on Deficiencies of Building Roofs

Abstract

Climate conditions affect buildings’ performance and durability. The purpose of this paper is to examine the influence of climate conditions on roof deficiencies. 763 cases of such deficiencies were analyzed in this regard. Once the construction deficiencies were quantified, they were characterized from a climatological point of view and their ‘climate location segments’ were studied to obtain ‘ranges of concentration of anomalies’ according to the obtained percentage. A direct relation is shown to exist between the location of the building (latitude, situation, type of climate, precipitation, thermal demands, and average wind speed) and a greater or smaller concentration of deficiencies found in both flat and pitched buildings. It was also found that an annual average wind speed greater than 3 m/s increases the appearance of deficiencies in roofs. A higher prevalence of deficiencies was also found in those geographical zones with a thermal demand of 1800–2800 heating degree days or 450–700 cooling degree days. It was found that a higher percentage of construction deficiencies are concentrated in buildings located in the northern coastal climate segments of Spain. With these results, technicians will be able to take more appropriate precautions during both the building process and the use and maintenance phase.

Impact of Environmental Exposure Conditions on the Maintenance of Facades’ Claddings

“…These parameters can include budget limitations, aesthetic appearance, desired condition level, local constraints, environmental exposure conditions, and the social and economic contexts of the building. Furthermore, based on the identified common relation between maintenance needs and design errors, the components' maintainability requirements and degradation performance are not always known to the building designers [23]. Frequently, the maintainability of the material is not a priority, which compromises the future maintenance activities and the costs throughout the service life [19].…”

Sustainable building repair: A K-means approach to addressing fissures in ceramic brick partition walls

“…Those judicial files were selected due to the filing of demands by building users against agents participating in the construction process, as a result of failures existing in construction elements in the buildings -namely, in this case, in internal partition walls. The failures detected between the years 2008 and 2017 and which resulted in subsequent demands were considered in this study [50]. In order to be able to include cases in the research, an additional condition was set, that the demands in question were already concluded and unappealable (their sentence was final and could not be appealed/sent to higher courts).…”
