Evaluation of thermal comfort conditions in a classroom with three ventilation methods

Abstract

The confirmation of the significantly elevated thermal neutral temperature can have a number of implications for both thermal comfort in an air-conditioned room and energy consumption of the associate air-conditioning system. With respect to the former, it provides scientific basis for the feasibility of elevated room temperatures, and with respect to the latter, it reveals considerable potentials for energy saving.

Building characteristics, indoor environmental quality, and mathematics achievement in Finnish elementary schools

“…It appears that low ventilation is related to both perceived poor air quality and high indoor temperature, which has also been reported in other studies [17,26,40].…”

“…Recent studies have also reported associations between inadequate ventilation and learning outcomes [13][14][15][16]. In addition to improved IAQ, proper classroom ventilation could also improve thermal comfort [17,18].…”

Effects of temperature and supply airflow rate on thermal comfort in a stratum-ventilated room

“…4). This finding is in good agreement with the previous result [35], where the neutral temperature of about 27 C was obtained. Especially, under 10 ACH and the room temperature of 27 C, the subjects sat at Seat No.…”

Prediction of thermal comfort, IAQ, and energy consumption in a dense occupancy environment with the under floor air distribution system

“…Although Zhang et al [13] and Fong et al [14] concluded that having an acceptable thermal environment from a well-designed UFAD system is possible.…”
