Indoor environments are characterized by several pollutant sources. As people typically spend more than 90% of their time in indoor environments. Thus, indoor air quality (iAQ) is recognized as an important factor to be controlled for the occupants’ health and comfort. The majority of the monitoring systems presently available is very expensive and only allow to collect random samples. This wor...

Abstract The presented paper deals with the assessment of selected indoor environmental quality (IEQ) factors, specifically parameters thermal comfort and air (IAQ), in two buildings a modern office complex. Both are LEED certified. monitoring IEQ risk factors took place spaces (cell open-space offices) representative all occupied areas under operating conditions. results real measurements IAQ ...

Poor indoor environmental quality (IEQ) has become a global concern for World Health Organization (WHO), and its impact on health well-being been exacerbated by the COVID-19 pandemic. To monitor sanitize air, this study develops cost-effective customizable IEQ monitoring system to detect unhealthy low-comfort air levels. This uses ThingSpeak (MATLAB), microcontrollers (Arduino Uno), various low...

Housing and its indoor environment influence inhabitants’ comfort, productivity, health. For this reason, it is becoming increasingly important to investigate the factors that affect environmental quality. Thus, numerous sustainability assessment systems have been developed evaluate building performance. This paper presents a model for evaluating of housing located in Biobio region Chile, integ...

On the base of the residential interior decoration and the air pollution status in China, as the requirements of indoor air quality at present are increasing, from the concept of healthy house, new idea is proposed that indoor air pollution is controlled by overall process through green interior design, selecting environmentally friendly materials and green decoration for safety, healthy and en...

While an ever increasing number of clients and professionals are committed to achieving high levels of energy and environmental standards in new and retrofit projects, the investment community still has not moved beyond first cost decisionmaking. The need for life cycle decisionmaking will depend on multiple national and international efforts to develop the financial algorithms and collect the ...

The adverse effects of contaminated outdoor air have been recognized and subject to control for many years. More recently environmental engineers and health professionals have become cognizant of the hazards associated with contaminated indoor air. It is now understood that contaminated indoor air negatively impacts human health, worker productivity, and physical property. Volatile organic comp...

This paper selectively reviews scientific research on the positive effects on building occupant’s health, well-being and productivity that result from the presence of indoor plants in the workplace. Case studies show improvement in indoor air quality, (with a reduction in the levels of volatile organic compounds (VOCs), improved productivity by up to 12%, and reduced absenteeism and staff turno...
