- 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.
- 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.
