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...

This study investigates indoor thermal comfort during heatwaves in dwellings of the Southern European city of Pamplona, Spain.

The rise in outdoor temperatures and heatwaves highlights the limitations of buildings in adapting to warming conditions, even in temperate climates. This paper analyses the indoor overheating of residential dwellings in Pamplona (a city in northern Spain, with a Cfb climate) using an urban-scale diagnostic methodology and presents different envelo...

This study examines the impact of heatwaves on indoor operative temperatures of dwellings in Pamplona (north of Spain) and presents a comparative analysis of a typical summer and two extreme summers with heatwaves in 2003 and 2022. The assessment was conducted in two neighbourhoods with different urban morphologies and built periods related to diff...

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 th...

Heat waves are expected to increase the use of air conditioning (AC), deriving in higher energy consumption. This research aims to determine whether thermal insulation is an effective retrofit strategy for tackling overheating. Four occupied dwellings in southern Spain were monitored: two houses built prior to any thermal criteria and two with curr...

Overheating in dwellings is a global concern that is increasing due to global warming and more frequent and extreme heatwaves. This study assesses the relationship between different building parameters (built period, floor level, orientation, window area and solar shading) and compares indoor overheating hours during summer in twelve apartments mon...

This paper investigates the relationship between indoor air quality (IAQ) and overheating in a temperate climate in Spain (Cfb attending to Koppen-Ggeiger classification), in dwellings located in residential buildings and without cooling systems. Twelve dwellings were selected among different Spanish building regulatory periods and quality of const...

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 compar...

Students spend at least 6 hours per day in a classroom so it is important to ensure adequate indoor environmental conditions in these spaces. This is especially relevant due to the proven relationship of indoor temperature and air quality with the feeling of tiredness, school performance and health of students. Currently, interest in this topic has...

Renovation at district scale is a key strategy to reduce CO2 emissions and energy consumptions by optimising the implementation of renewable energy sources and taking advantage of economies of scale. In this context, this paper focuses on assessing the positive impacts and difficulties after the energy rehabilitation of thermal envelopes in two bui...

In Spain and other Mediterranean countries, some museums lack of cooling and ventilation systems. They usually are located in historical buildings with heritage protection requirements. This is particularly complex in a building with a use that has to attend to comfort conditions for visitors and workers, and to very specific and demanding indoor t...
