- Exploring indoor thermal comfort and its causes and consequences amid heatwaves in a Southern European city—An unsupervised learning approach(Elsevier Ltd., 2024) Arriazu-Ramos, A. (Ainhoa); Monge-Barrio, A. (Aurora); López-Hernández, D. (Dolores); Gamero-Salinas, J. (Juan); González-Martinez, P. (Purificación); Sánchez-Ostiz, A. (Ana)This study investigates indoor thermal comfort during heatwaves in dwellings of the Southern European city of Pamplona, Spain. Utilizing K-means and Hierarchical clustering, it explores clustering patterns from occupants’ survey responses (n = 189) to thermal comfort-related questions (i.e. day and night thermal sensation, thermal satisfaction and thermal preference) as well as causal links (i.e. indoor temperatures, building/occupant features) and consequences (i.e. sleep quality, heat-related symptoms) of such clusterings. Both unsupervised learning techniques coherently revealed two groups: the comfortable and uncomfortable clusters. Uncomfortable occupants coherently experience more sensation to heat, greater preference for cooler temperatures, and more thermal dissatisfaction, especially during daytime hours. Dwellings of comfortable occupants experience median indoor temperatures ranging 25.7–26 ◦C; dwellings of uncomfortable occupants 27.4 ◦C, with median temperatures above 28 ◦C during 15:00–23:00 and 23:00–07:00 periods. Discomfort or overheating—coherently expressed by the thermally uncomfortable cluster—is alleviated by multiple factors related to the presence of active cooling technologies in all rooms, and use of passive and low-energy cooling measures (e,g. fans); exacerbated by heatwave conditions. As coherently expressed by the uncomfortable cluster heat worsens the sleep quality of occupants (3 to 6-fold) and increases the likelihood of occupants to experience heat-related symptoms (10–19-fold). This study is particularly important to policymakers, as it sheds light, from dwellers’ first-hand experience in a Southern Europe city, on relevant factors that should be taken in consideration to allow them to cope better with heatwaves without compromising their comfort and health.
- From urban microclimate to indoor overheating: Analysis of residential typologies during typical climate series and extreme warm summer(Elsevier, 2023) Arriazu-Ramos, A. (Ainhoa); Pons-Izquierdo, J.J. (Juan José); Ramos-Ruiz, G. (Germán); Monge-Barrio, A. (Aurora); Sánchez-Ostiz, A. (Ana)Indoor overheating is a current problem due to increasingly higher external temperatures and more frequent and extreme heatwaves which specially impact naturally ventilated dwellings. This paper presents a methodology at neighbourhood-scale to analyse indoor overheating hours (IOH) of residential typologies and to investigate building parameters that most influence IOH. This study is based on energy simulations for two climate scenarios: typical meteorological year and extreme warm summer with heatwaves (2022), and the effect of urban microclimate is considered by using the Urban Weather Generator tool. Results with the typical meteorological year show 0% IOH for all dwellings, while those derived from simulation with summer 2022 show a significant increase in IOH with values above 30% IOH in the most overheated ones. The effect of microclimate is especially relevant in the extreme warm summer and increases the IOH by 7,5% on average. Among the building parameters studied, the number of orientations (related to potential of natural ventilation), orientation and the floor level of the dwellings have the highest influence on IOH. These results could help policy-makers and technicians detect the risk of overheating in cities and buildings and prevent it by improving the adaptation of the residential stock to current warming.
- Pedagogical prospection of the metaverse through curatorship. Case study of the 1964 IBM pavilion as an example of curatorial pedagogy(Elsevier, 2023) Antón-Sancho, J. (Javier) NO USAR; Reina-Uribe, T. (Teresa); Urpí-Guercia, C. (Carmen); Basanta-Vázquez, C. (Carmen)In an effort to explore the potential of the metaverse in the field of curatorship, as a space of convergence between education and communication, this article presents a descriptive case study of the IBM Pavilion designed by Eames and Saarinen for the 1964 New York World Fair. As an exhibition project that anticipated the possibilities of computers through an immersive experience in a changing historical moment, it opens up for the present new scenarios for imagining how to approach the metaverse. Conclusions are drawn according to the initial theoretical framework with an interdisciplinary focus on the context of uncertainty in the emergence of the metaverse and its pedagogical possibilities through the development of crosscutting capabilities in citizens.
- Encouraging natural ventilation to improve indoor environmental conditions at schools. Case studies in the north of Spain before and during COVID(Elsevier, 2022) Dorregaray-Oyaregui, S. (Sara); Arriazu-Ramos, A. (Ainhoa); Martin-Calvo, N. (Nerea); Bes-Rastrollo, M. (Maira); Monge-Barrio, A. (Aurora); López-Hernández, D. (Dolores); González-Martinez, P. (Purificación); Sánchez-Ostiz, A. (Ana)The COVID pandemic has strongly affected daily life both in Spanish schools and worldwide. Providing the best environmental conditions for children allowing face-to-face learning with healthy and safe indoor spaces is a challenge. In the present study, empirical research about how these environmental conditions change with COVID is presented comparing the situation from March 2020 to January 2021. The methodology combines surveys conducted in nine schools with a case study in a selected school where a detailed monitoring of the building was developed during both heating seasons. This data ana- lyzes the impact of the new COVID prevention protocols on indoor environmental conditions (especially those related to natural ventilation). Results show a mean CO2 reduction of 1,400 ppm, having in the sec- ond term values around 1,000 ppm, although temperatures diminished nearly 2 °C to mean values of 18 °C. Evolution of temperature and CO2 concentration throughout the day was also analyzed, being these indoor conditions especially important for the children with poorer health. Mechanical ventilation with heating recovery should complement natural ventilation, at least during the coldest months or hours of the day, although systems have to be carefully designed and installed to work effectively.
