- Training for sustainable and healthy building for 2050: New methodologies for an integrated and transnational education approach targeting skills development for the transition toward ZEB and PEB buildingsPublication . Koukou, Maria; Lucas, Susana; Justino, Júlia; Rafael, Silviano; Livieratos, Antonios; Carriço, Nelson; Konstantaras, John; Vrachopoulos, Michail; Benedetti, Anna Chiara; Mazzoli, CeciliaThe development of existing technologies and the emergence of new technologies aiming at the total decarbonization of the buildings sector by 2050 requires and encourages upskilling and reskilling of existing professionals as well as the development of new subjects from higher education courses to be able to respond to the demands of these challenges. In responding to those challenges, the main objective of the research is to design, implement, and evaluate a novel, integrated, and transnational educational approach aimed at equipping professionals and students in the construction sector with the necessary skills to achieve sustainable and energy-efficient buildings. This study aligns with the European Union’s 2050 decarbonization goals by developing innovative methodologies that address the multidisciplinary challenges of sustainable building design, operation, and renovation. The proposed educational approach was developed in the framework of an Erasmus+ project entitled “Training for Sustainable and Healthy Building for 2050 (BUILD2050)”. Six higher education institutions from five European countries joined forces to create transversal skills in the building sector knowledge for emerging challenges through an integrated training composed of eight training courses for students and professionals of the construction area. In this work, the pedagogical approach used to develop the course contents, curricular development issues, technology, and infrastructure, as well as student support, the results obtained from the evaluation carried out after the pilot training of the eight training courses, and best practices and lessons learned, are presented and discussed. The courses’ learning objectives, the learning material, and the assessment activities were well-accomplished. However, based on the feedback of students and teachers, some improvements for future editions of the courses are required.
- An information system for infrastructure asset management tailored to portuguese water utilities: platform conceptualization and a prototype demonstrationPublication . Carriço, Nelson; Ferreira, Bruno; Antunes, André; Grueau, Cédric; Barreira, Raquel; Mendes, Ana; Covas, Dídia; Monteiro, Laura; Santos, João Filipe; Brito, Isabel SofiaThis paper describes a new information system developed as part of the Portuguese R&D project DECIdE. The project aimed at the development of a platform for infrastructure asset management tailored to Portuguese water utilities. The platform allows the integration of different data from several information systems of the water utilities and includes several tools for the performance assessment of the water supply systems in terms of water losses, energy efficiency and quality of service (i.e., water and energy balances and key performance indicators). The developed platform was tested with data from five small to medium size Portuguese water utilities with different maturity levels in terms of technological and human resources. The obtained results are very promising because the platform allows for periodic system performance assessment which constitutes an important part of the infrastructure asset management for small and medium-sized water utilities.
- Urban water infrastructure asset management plan: case studyPublication . Ferreira, Bruno; Carriço, NelsonThe current paper aims the application of the Portuguese infrastructure asset management (IAM) methodology to a case study. The inevitable degradation of urban water infrastructures creates new challenges forwater utilities engineers and manager, as they need to decide which components should be rehabilitated to efficiently match the public’s demand, while still providing a qualitative and efficient service that doesn’t compromise the financial integrity of water utilities. This methodology is based on a five-step structured sequence - (i) definition of objectives assessment criteria and metrics; (ii) diagnosis; (iii) plan production; (iv) plan implementation; and (v) monitoring and revision – being structured in three distinct levels of planning and decision (i.e., strategic, tactical and operational). The IAM methodology was applied to a sixty-year-old water supply system (WSS) located in Lisbon’s metropolitan area, Portugal, mainly focused on steps (i) to (iii) and to the tactical level of planning. Results obtained are discussed and the main conclusions are presented.
- Development of Hybrid Braided Composite Rods for Reinforcement and Health Monitoring of StructuresPublication . Rana, Sohel; Zdraveva, Emilija; Gonilho-Pereira, Cristiana; Fangueiro, Raul; Correia, A. Gomes
- Performance Assessment of Waste Fiber-Reinforced MortarPublication . Gonilho-Pereira, Cristiana; Faria, P.; Fangueiro, R.; Martins, A.; Vinagre, P.; Ratão, S.In this paper an experimental work is presented which main objective is the evaluation of the influence of different percentages of waste fibrous materials usage on the performance of fiberreinforced mortars. Moreover, the influence of binder type is evaluated. Therefore mortars were produced with two different binders – cement and powder hydrated lime. Mortars performance evaluation was carried out through flow table and plunger penetration consistency, dynamic modulus of elasticity, flexural and compressive strength, capillary absorption, drying index and adherence tests. The benefits revealed in some characteristics of both mortars by the use of waste fibers are discussed.
- Self-sensing Hybrid Composite Rod with Braided Reinforcement for Structural Health MonitoringPublication . Rosado, K.; Rana, S.; Gonilho-Pereira, Cristiana; Fangueiro, R.Enhancing the performance and lightness of different structures has already been achieved by the employment of fibre reinforced composite materials. Nowadays, a new challenging perspective is being given to these materials by the inclusion of non-metallic conductive components. This emerging technology will lead to multifunctional composites with possible applications in structural health monitoring and traffic monitoring. The aim is to avoid corrosion problems from metallic components, as well as to eliminate the need of expensive equipments used for the health monitoring of large infrastructures. In the present research, the strain-sensing capability of a core-reinforced hybrid carbon fibre/glass fibre braided composite has been investigated in order to develop continuous monitoring system. The characterization of sensing behaviour was performed with the help of an instrumental set-up capable of measuring the change in electrical resistance with mechanical stresses applied to the samples. The effect of core composition (carbon fibre/glass fibre weight ratio) on the strain sensitivity of the braided composites has been studied in order to find out the optimum composition for best sensing capability. Among the three compositions studied (23/77, 47/53 and 100/0), composites with lowest amount of carbon fibre showed the best strain sensitivity with gauge factors up to 23.4 at very low flexural strain (0.55%). Attempts have also been made in this research to develop a piezoresistive matrix for the braided composites in order to further enhance their strain sensitivity. For this purpose, the strain sensing capability of an unsaturated polyester matrix dispersed with chopped carbon fibres (1mm and 3 mm lengths) at various weight % (0.5, 0.75 and 1.25%) was evaluated in order to find out their optimum length and concentration. It was observed that chopped fibres with different lengths showed similar strain sensitivity, which however, improves with the decrease in their concentrations.
