He is former chair of Standards Project Committee 62.2P, Ventilation and Acceptable Indoor Air Quality for Low-Rise Residential Buildings. s HVAC&R professionals, our major concern is the engineering of indoor envir...

Energy Efficiency and Indoor Air Quality in the healthcare applications and particularly in surgical operating theatres are important features in modernized designs. The various reasons for deviation from obtaining optimum IAQ and energy efficient buildings are listed. The air conditioning systems serving the operating rooms require careful design to minimize the concentration of airborne organ...

Introduction Studies of school environment and related health diseases in pediatric population have been performed recently. The European Commission, through the Directorate General for Health and Consumer Affairs, funded the study on Health Effects of School Environment held in different European countries. Levels of air pollutants can be several folds higher exposures are prolonged. Since chi...

The Covid-19 outbreak has resulted in new patterns of home occupancy, the implications which for indoor air quality (IAQ) and energy use are not well-known. In this context, present study investigates 8 flats London to uncover if during a lockdown, (a) IAQ monitored deteriorated, (b) window operation by occupants changed, (c) more effective ventilation could enhance without significant increase...

Sixteen flights had been investigated for indoor air quality (IAQ) on Cathay Pacific aircraft from June 1996 to August 1997. In general, the air quality on Cathay Pacific aircraft was within relevant air quality standards because the average age of aircraft was less than 2 years. Carbon dioxide (CO2) levels on all flights measured were below the Federal Aviation Administration (FAA) standard (3...

Abstract Assessment of indoor environmental quality has recently moved to a combined methodology both measurements and questionnaire surveys. In this study, we have used data from the national survey Swedish housing stock, BETSI, conducted in 2007/2008, during heating season. The study included, among others, measurement selected air pollutants an extensive on occupants’ perception their dwelli...
