“…This parameter is of particular importance if a building under construction is not insulated in the same year, then one should choose materials, resistant to temperature change. The facade wall material and wall structure durability have the heavy reliance on the number of freeze-thaw cycles in a year (Toni et al, 2014). The roof durability and excellent thermal properties depend not only on the humidity and air movement in roof construction but also on the coating material, colour and shape (Alchapar and Correa, 2016).…”

This article aims to create a theoretical evaluation model based on decision support methods for the residential house construction materials and elements selection. The research and analyses of most of the scientists are invoked on individual elements and materials of the building, which have an impact on different aspects of sustainability. Meanwhile, the integrated model covering all the key elements and materials of the single-family residential house has not been implemented. Thus, the problem of development of the general composite model of the element and material selection of single-family buildings is acute in many countries around the world. Our study assessed the specific technical parameters related to building materials: cost, thermal bridging, and load-bearing capacity, the outer material selection according to localisation, environmental performance, durability, weight. SWARA (Step-wise Weight Assessment Ratio Analysis) approach is applied to decision making to calculate the relative importance of the criteria. A single-valued neutrosophic set governs the proposed new extension of MULTIMOORA (Multiobjective Optimisation by Ratio Analysis Plus Full Multiplicative Form) method and allows to deal explicitly with the indeterminacy of the initial information. Our proposed new theoretical composite model for selection of elements, materials and other aspects of sustainability can be practically applied in creating the decision support system for the selection of single-family house elements and materials.

“…Previous studies [1][2][3] have shown that the deterioration rate of outdoor exposed concrete structures in Finland is highly dependent on geographical location and the direction in which the structure faces. Pakkala et al [2] presented that the severity of the freeze-thaw attack is heavier in coastal areas, leading to faster freeze-thaw damage. In a recent study, Pakkala et al [3] presented that the corrosion rate in carbonated concrete is significantly higher in coastal areas than in other locations and for south-west-, south-and south-east-facing structures.…”

“…If one of them is excluded, there will be no deterioration. The Finnish climate is quite harsh for porous building materials such as concrete and masonry because of quite high winddriven rain (WDR) amounts with almost perennial potential for freeze-thaw cycles while, especially during autumn, the possibilities for structures to dry are poor [2,3]. In addition, the existing concrete building stock has been shown to have large variation in quality because of lack of knowledge and regulation during its construction [1].…”

It has been shown in previous studies that the existing precast concrete element building stock in Finland has quality issues, especially with freeze-thaw durability and reinforcement corrosion. In addition, it has been presented that deterioration rate is the fastest in coastal area and decreases towards north which has been supposed to be a reason of lower amount of wind-driven rain (WDR). The aim of this study was to examine the connection between the amount of WDR on structures and the freeze-thaw damage more comprehensively. Condition investigation reports of 472 precast concrete element buildings were reanalysed to study the relation and the results were compared to climate data of the same time period to study the correlation between condition investigation observations and the amount of WDR. In addition, the observations made in a condition investigations and their relation to climate load at the same building were studied as a case study. The results show that there is a significant connection between the WDR related climate load and the freeze-thaw damage occurrence. The results can be used to plan protective methods and be a base for service life estimations.
