A windcatcher (wind tower, wind scoop) (Persian: بادگیر, Arabic: برجيل) is a traditional architectural element used to create cross ventilation and passive cooling in buildings. Windcatchers come in various designs: unidirectional, bidirectional, and multidirectional. Windcatchers are widely used in North Africa and in the West Asian countries around the Persian Gulf, and have been for the past three thousand years.Neglected by modern architects in the latter half of the 20th century, the...

Thermal comfort varies significantly between individuals and regions depending on factors such as activity level, clothing, space temperature and relative humidity. This study considers the estimation of thermal comfort parameters such as air temperature, mean radiant temperature, air velocity, emissivity of space, metabolic rates, and heat transfer coefficients to determine comfort index, predicted mean vote, and predicted percent of dissatisfied people. Several equipment were employed to...

There is good evidence supporting the airborne transmission of many respiratory viruses (measles, influenza A, human rhinovirus and the novel SARS-CoV-2). Relative humidity (RH) is an important factor in understanding airborne transmission as it may impact both airborne survival, inactivation by biological decay, and the gravitational settling of the virusladen droplets. This study aimed to estimate and compare the impact of indoor relative humidity on the airborne infection risk caused by...

High temperature makes the children uneasy during classroom activities. This study examines the effect of air temperature to children‟s cognitive performance. The school profile was determined such as: the total number of teachers, number of enrollees, land area (sq.m.), number of buildings and number of trees was determined to support the analysis of the data collected. The respondents were the Top thirty (30) Grade V pupils from public city elementary school in the Bicol Region. The...

Monitoring the thermal comfort of building occupants is crucial for ensuring sustainable and efficient energy consumption in residential buildings. Existing studies have addressed the monitoring of thermal comfort through questionnaires and activities involving occupants. However, few studies have considered disabled people in the monitoring of thermal comfort, despite the potential for impairments to present thermal requirements that are significantly different from those of an occupant...
