- Teaching Fire Safety in Schools of Architecture: The Spanish Case(2023) Echeverría-Trueba, J. B. (Juan B.); Fernández-Vigil, M. (María)Fire safety teaching in schools of architecture has become more relevant over the last years in Spain due to the influence that it has in the professional architectural project. The introduction of fire safety knowledge in the intermediate courses of architectural studies has important advantages for the student, who quickly perceives the project as a normative discipline. However, fire safety regulations are complex and difficult to understand for the students. The experience along the last years has progressively evolved from an analysis of the legal documents to a more frequent use of graphical representations. A combination of symbols, diagrams, and simple drawings has proven to be quite effective: Symbols act as anchor repeated throughout the learning process. Diagrams are a first approach to the characteristics of the building. And the simple drawings complete the information so the students can work on the proposed exercise.
- Elderly at Home: A Case for the Systematic Collection and Analysis of Fire Statistics in Spain(2019) Echeverría-Trueba, J. B. (Juan B.); Fernández-Vigil, M. (María)At the present time, there is no nation-wide, systematic approach to collecting, analyzing and presenting fire loss data in Spain. This makes it very difficult to understand the fire problem in general, and more specifically with respect to vulnerable populations, such as the elderly. As first steps to overcome the lack of a nationally populated and managed fire incident database, a methodology for collecting fire data, based on information extracted from the media, was developed. This approach is modeled in part on the Fire Incident Data Organization system from the National Fire Protection Association in the United States, which identifies significant fires through a clipping service, the Internet and other sources. For the initial Spanish database, selected variables were chosen from similar statistics gathered in other countries. The variables are related to the place and moment of the fire, its causes and consequences, the building typology and state, and the fatal and non-fatal victims involved, among other factors. In the initial data set, data concerning residential fires occurred between January 2016 and December 2016 was collected, and variables were analyzed. An initial focus was to identify the risk factors for one of the most vulnerable groups in case of fire, the elderly people. The development of this first-ever nationally-representative database of fire incidents in Spain is overviewed, and analysis of elderly population in dwelling fires is presented as a study case that represents the value and need of such a national database in Spain.
- Architectural Fire Protection Learning: the ETSAUN Case(Politecnico di Milano, Italia, 2013-09-17) Echeverría-Trueba, J. B. (Juan B.); Zapata-Martínez, O. (Omayra); Martín-Gómez, C. (César); Villanueva, S. (Sonia); Mambrilla-Herrero, N. (Natalia)Fire protection is a main parameter in the design of buildings, although it is often neglected in the Schools of Architecture because is being considered an “engineering thing”. In Spain, the education system provides a minimum dedication for this matter, but in the case that will be presented in the paper, it has been taken to a higher level. This is because fire protection is provided in three courses as we described in the article. This article will show the teaching itinerary in Architecture Studies Degrees explaining the dynamics of each of the three courses in which students are trained in fire protection, illustrated with real examples of work from the students themselves. We anticipate here that in the first year, students learn the theory, its impact on the Project; in the second year of learning, they relate it to the project at hand; and in the third, this time independently, consolidate learning in a complex project that takes place over two semesters. This teaching experience includes also the description from developing apps for smartphones, to the students practices of fire protection in the Laboratory. Far away from the opportunity of research and specialization that Fire Safety provides for future architects and construction engineers, it must be taken into account that Fire Safety it is not a limitation, Fire Safety becomes more real the architectural project.
- Empirical evaluation of EnergyPlus infiltration model for a case study in a high-rise residential building(Elsevier, 2023) Echeverría-Trueba, J. B. (Juan B.); Casquero-Modrego, N. (Nuria); Fernández-Bandera, C. (Carlos); Bastos-Porsani, G. (Gabriela)The European Council has proposed reducing buildings’ energy consumption as one way to decarbonization by 2050. Currently, digital twins are used for real-time energy management, but there are discrepancies between predicted and measured energy performance due to uncertainties in building energy models (BEMs). Air leakage is a key parameter that is difficult to obtain and EnergyPlus users often employ a constant value or apply air leakage equations with pre-determined coefficients. This research is a preliminary step in reducing this uncertainty in the author’s methodology of BEMs calibration, using EnergyPlus and measured data. The study empirically verifies the ability of the EnergyPlus model’s design flow rate to accurately replicate dynamic infiltration values within a zone of a high-rise residential building, where a tracer gas test using CO2 and a blower door test were conducted. Three new methods for calculating Idesign were developed and evaluated. The results were assessed based on the American Society for Testing Material D5157 (Standard Guide for Statistical Evaluation of Indoor Air Quality Models). The models generated with ad-hoc coefficients were compared to those from the literature (EnergyPlus, DOE-2, and BLAST). Among the models with off-the-shelf coefficients, the one with Idesign calculated with in situ data and DOE-2 coefficients demonstrates an accuracy that is only 26% lower than the best model with regression coefficients, which has an R2 value of 0.94 and an NMSE value of 0.02 in the training period.
- Industrialized Sunspace Prototype with Solar Heat Storage. Assessment of Post-Occupational Behaviour in Adaptive Facades.(TU Delft Open, 2015) Echeverría-Trueba, J. B. (Juan B.); Ramos-Ruiz, G. (Germán); Domingo-Irigoyen, S. (Silvia); Monge-Barrio, A. (Aurora); Fernández-Bandera, C. (Carlos); González-Martinez, P. (Purificación); Sánchez-Ostiz, A. (Ana); Torres-Ramo, J. (Joaquín)The thermal performance of two passive solar components has been investigated. An attached sunspace with horizontal heat storage and another one with vertical thermal storage were designed in order to optimize the use of solar gains and its storage and distribution in an industrialized component. These sunspaces have been tested under real conditions, comparing their thermal performance with two commonly used components in residential buildings in Spain: a window and a double window making up an attached sunspace. Different series of experimental measurements were conducted in two test-cells exposed to outdoor conditions in Pamplona (Northern Spain). As a result, nine scenarios during winter 2011 and six during summer 2012 have been carried out, comparing all of the prototypes two by two with different use modes. Results show that a sunspace with heat storage takes advantage of the solar energy and improves the indoor thermal performance of the adjacent room during winter in a better way than a window or a simple sunspace, and that it also offers better performance in summer. The best results in winter and summer were obtained when an appropriate use of the component was performed, in concordance with outdoor conditions. Several thermal control keys for the use of these components are suggested.
