They teach subjects related to these areas, in addition to mathematics and digitalization. They also collaborate with researchers from the University of the Basque Country in the field of teaching innovation. They have been progressively implementing a teaching method based on problembased learning (PBL), which moves away from the traditional approach of theoretical teaching, obtaining greater student involvement and better academic results. In addition, they participate in two International Cooperation Agreements with the Chouaib Doukkali University (El Jadida) and with the Abdelmalek Essaádi University (Tétouan), both located in Morocco, and a Memorandum of Understanding with the Pusan National University, in South Korea. Thanks to them, it has been possible to develop actions such as the exchange of students and researchers, postgraduate training in Master and Doctorate, joint participation in research and technological development projects, the dissemination of the obtained research results, and the promotion of the transition from the laboratory to open digital educational resources in engineering. In addition, it has made it easier for postgraduate students from Morocco to carry out the experimental part of their research in the facilities of the University of Burgos.

A case study for a tertiary building Briones Llorente, Raúl; Montero García, Eduardo Achieving a reasonable level of airtightness is important for the energy efficiency of living spaces and the comfort of occupants. The benefits of improved insulation levels and more energy efficient heating systems are lost if warm air can leak out of a building and cold air can leak in. Poor airtightness can be responsible for up to 40% of heat loss from buildings. Airtight buildings require airtight windows. Airtightness of windows is often evaluated in lab conditions in the context of initial type testing. Testing methods can be found in several international standards, leading to airtightness classifications of windows for building codes. The level of airtightness achieved is measured as air permeability, as the quantity of air that leaks into or out of the window per hour. Airtightness of windows is typically expressed per meter opening joint or per square meter. Nevertheless, airtightness of window is highly sensitive with respect to wind conditions, mostly speed and direction. Increased attention to energy efficiency and airtightness of buildings has led to more research on the performance of windows, and can be estimated by appropriate simulation. This work presents a case study of the influence of wind speed and direction on the thermal load of a tertiary building due to leakage through windows. Transient simulation by means of Transient System Simulation (TRNSYS) package is presented. Results are analyzed as a function of standardized window type. Besides, relative influence of the internal layers of the façade on the thermal load of the building is studied. Three alternative cases of high thermal inertia are compared with the existing one with low thermal inertia.
