ARCHITECTURAL MEASURES FOR FACILITATION OF INDOOR AIR QUALITY IN BUILDINGS

Indoor Air Quality of Office Buildings in the Helsinki Area

Indoor air quality (IAQ) was investigated in 19 open-plan offices and 30 office rooms in order to compare the differences in these two different types of office environments. No moisture or mold problems had been reported from the present buildings, but the employees had complained about the IAQ. The results revealed only slight differences in the IAQ of the two different types of office enviro...

Indoor Air Quality and Severity of COVID-19: Where Communicable and Non-communicable Preventive Measures Meet

Study of Dioxide Carbon Concentration and Indoor Air Quality in Some Buildings in the Equatorial Region of Cameroon (Yaounde)

Background and purpose: Elevated CO2 rate in a building affect the health of occupant. This document presents results of an experimental analysis conducted in 50 offices located in 12 buildings with different layer in Cameroon (Yaounde). This study took place in 2012, during the dry and the rainy seasons. The main goal is to show the influence of the building structure, the ventilation and the ...

Air Quality and Thermal Comfort in Office Buildings: Results of a Large Indoor Environmental Quality Survey

This paper presents results of over 34,000 survey responses to air quality and thermal comfort questions in 215 buildings in US, Canada, and Finland. Results show that 80% or more of the occupants expressed satisfaction with their thermal comfort in only 11% of the buildings surveyed. Air quality scores were somewhat higher, with 26% of buildings having 80% or occupant satisfaction. With respec...

A Dual Airflow Window for Indoor Air Quality Improvement and Energy Conservation in Buildings

This paper proposes a novel dual airflow window for use in residential buildings that tempers outdoor air with exhausted indoor air. The energy needed to condition outdoor air is reduced because of the counterflow heat exchange between the two flow streams. Experimentally validated computational fluid dynamics (CFD) simulations have been used to optimize the window design and to estimate the be...
