Quantifying Fenestration Effect on Thermal Comfort in Naturally Ventilated Classrooms [PDF]

open access: yesSustainability, 2021
This study seeks to evaluate thermal comfort in naturally ventilated classrooms to draw sustainable solutions that reduce the dramatic energy consumed in mechanically ventilated spaces. Passive ventilation scenarios are generated using alternations of openings on the windward and leeward sides to evaluate their effects on thermal comfort.

Control of CO2 in a Naturally Ventilated Classroom

Energy and Buildings, 2008
Abstract The ventilation performance of a naturally ventilated classroom was investigated to monitor the CO 2 levels and compare compliance with new guidelines. Measurements of CO 2 levels were taken for 1 week during the heating season while different ventilation modes were investigated.

Effect of natural ventilation and manual airing on indoor air quality in naturally ventilated Italian classrooms

Building and Environment, 2016
Abstract The present work aimed to evaluate the effect of the ventilation on indoor air quality in Italian classrooms. To this end, schools located in the Central Italy were considered in the survey. The results of two experimental analyses are presented: a) data on classrooms' permeability and resultant air exchange rate, b) trends of indoor air ...

Modeling of Occupant-Generated CO2Dynamics in Naturally Ventilated Classrooms

Journal of Occupational and Environmental Hygiene, 2004
A numerical method is presented to estimate the concentration of occupant-generated CO(2) for the (time-varying) occupancy typically found in nonforced ventilated elementary school classrooms. Here, the governing mass balance was solved numerically and compared to experimental measurements in order to estimate the respiration and (time-varying ...

Natural ventilation performance of classroom with solar chimney system

Energy and Buildings, 2012
Abstract The considered Zero Energy Building is a three-story building located in Singapore which was recently retrofitted in 2009 with a range of green features. A solar chimney system was constructed to enhance the air ventilation within the interior spaces using a series of solar assisted ducts that linked the lower floor classrooms and upper ...

A Comparison of Student Performance Between Conditioned and Naturally Ventilated Classrooms

Building and Environment, 2015
Abstract This study presents a comparison of classroom learning performance between courses taught in naturally ventilated (NV) rooms and air-conditioned (AC) rooms. This is done to examine effect of thermal comfort standard followed — PMV based or adaptive thermal comfort — on learning.
