“…It is also 0.4 • C higher than the comfort temperature calculated for summer in NV classrooms in India [62]. The comfort temperature of this study is 2.2 • C higher than the study conducted under a high metabolic rate of students during autumn and also found that female students had higher comfort temperatures than males [33]. The comfort temperature of the adults in university is estimated at 26.5 • C [64].…”

“…They also reported that adaptation to the thermal environment is influenced by factors such as age, climate, and mode of buildings operation. The comfort temperature of the university students under high metabolic rate during autumn was well fitted within the temperature limits of the ASHRAE standard [33]. A one-year study in university campuses in Portugal showed that clothing behaviour and clothing insulation are key issues in the estimation of comfort temperature [34].…”

“…Although studies on thermal comfort usually focus either on peak summer or peak winter, the present study was conducted not in peak summer, but in middle autumn. Some previous studies also focused on the middle season [14,19,33,38,47]. Therefore, even from a survey not in the summer peak, we considered that meaningful results could still be obtained.…”

A comfortable indoor environment is essential for students' health and academic performance in schools. As no major concerns were raised on the thermal comfort of students in Nepalese schools, we investigated the present condition of students' thermal comfort in school buildings in the temperate climatic region of Nepal. A survey was conducted on the indoor thermal environment and the associated thermal perception during the middle autumnal season in 2017. Altogether, 818 students participated in this survey; they voted three times: at the beginning, in the middle, and at the end of each 45-min lesson. Under the condition of natural ventilation, the indoor globe temperature was close to the outdoor air temperature. Approximately three quarters of the students felt comfortable at an average temperature of 27 • C. Private school students perceived a low estimated comfort temperature, which may be due to wearing more clothing insulation. Even though there is a dress code, students reduced their clothing to adapt to outdoor thermal environment, whose air temperature is above 30 • C. This study provides the adaptive thermal comfort system for Nepalese school students under natural ventilation during the middle autumnal season.

The Influence of Building Renovations on Indoor Comfort—A Field Test in an Apartment Building

2020

View full text Add to dashboard Cite

This article presents a field test of how deep renovation affects indoor climate quality. The studied apartment building was built in 1968 and is located in Finland, within the Nordic climate zone. The deep renovation included façade repair with extra insulation, new windows with trickle vents, new balcony glass and doors, and the installation of an exhaust air heat pump into the existing mechanical exhaust air ventilation. The indoor climate conditions and building envelope tightness were measured before and after the renovation. As a result of these energy renovation measures, the building envelope tightness improved by nearly 40% and the uncontrolled supply of air (draughts) decreased by approximately 24%. The overall energy consumption of the building decreased by 45%. Above all, the long testing period gives credibility to the study. The field test brought up the challenge of supplying an adequate amount of fresh air. This article highlights the fact that windows are part of a mechanical ventilation system if fresh air is not controlled by being led through inlet ducts. The supply air flow and volume must be ensured by correctly dimensioned valves, and therefore we stress the importance of the technical cooperation of technical designers.
