“…Hallowell et al [30] suggested that in the construction industry, expert identification could be conducted through the membership of nationally recognized committees or by participation in similar studies. The expert should meet at least four of the following requirements: (1) at least five years of professional experience in the construction industry; (2) tertiary education degree in the field of civil engineering or other related fields; (3) professional registration in the field of construction; (4) member or chair of a nationally recognized committee for the ETICS; (5) writer or editor of a book or book chapter on the topic; (6) faculty member at an accredited institution of higher learning; (7) invited to present at a conference on the topic; and (8) primary or secondary writer of at least three peer-reviewed journal articles.…”

The European climate strategy has encouraged the usage of the External Thermal Insulation Composite System (ETICS) to increase the energy efficiency of external building envelopes. This externally and relatively easily applicable façade solution must meet various technical requirements. This paper develops a technical severity evaluation model of on-site construction activities of ETICS to prioritize the risks of the construction process. The model can be used independently by any stakeholder of the construction process. The relevance of the activities is assessed with the Failure Mode Effects Analysis method. The model weights the impact of the essential technical requirements and simulates an integrated weighted technical severity value, which is derived from the analysis of experts’ judgments validated with the non-parametric Friedman’s test. The data collection for probability of occurrence and difficulty of detectability follows the Delphi technique to quantify the opinions of a group. The simulation, conducted on 103 degradation factors, shows that the on-site construction activities of ETICS strongly influence the decrease in the technical resilience of long-term durability, mechanical resistance, and stability, as well as the ability to bypass tensions. The highest risk is detected by the shortcomings in the layers of substrate, reinforcement, adhesive, and additional details.

“…The list of shortcomings was formulated from descriptive instructions, recommendations, harmonized standards and set requirements [9,[22][23][24][25][26], research regarding simulations or material studies conducted in laboratory conditions [12][13][14], field research [3][4][5]34,[52][53][54][55][56][57][58][59][60][61][62][63][64], and books on the topic [6,10,11]. The selected factors were verified by two experts, who had more than 12 years' experience with ETICS.…”

“…The study found that the construction process activities are responsible for 66% of the cases of failure. Neumann [6], on the other hand, assumes that three-quarters of the failures due to on-site construction activities are avoidable. Defects caused during the construction process affect the performance of the system and incur financial consequences.…”

“…Much research in the field of ETICS observes the quality aspects in isolation, making a rational relevance comparison impossible. The case studies of deteriorations have been diagnosed in several books [6,10,11], as well as studied in the controlled environment laboratory [12][13][14]. These and many other studies reveal a number of possible causes which should be compared to a single system.…”

Modelling the Technical–Economic Relevance of the ETICS Construction Process

The increased number of energy efficiency requirements of the European Union has increased the renovation rate of apartment buildings. The external thermal insulation composite system (ETICS) is often used to upgrade the façade. However, the construction process shortcomings very often cause defects shortly after completion. This paper develops a technical-economic relevance assessment model of the onsite degradation factors for better quality assurance in an SME. The model quantifies the technical significance of the degradation factors along with the future repair costs. The technical severity of 103 factors is evaluated by 12 experts, and the data is validated with the Friedman's test. The occurrence ratio, detectability, and latency period are foreseen by five experts and validated with the Delphi technique. The results of the three sample simulations emphasize the activities during substrate preparation and application of adhesive as well as a base coat with reinforcement mesh. The application of a finishing coat and installation of insulation plates have less relevance. It is recommended to upskill the craftsmen in regard to working with mixtures as the shortcomings are covered simultaneously and the failure detection period is short. The measures to protect against external weather effects are recommended due to their relatively high impact. Half of the shortcomings appear during the first two years.
