IAQ based demand controlled ventilation (DCV) is the subject of th where CO2 concentration is the subject of that paper where CO2 concentration is used as the controlling index of human produced contamination , and TVOC concentration as the controlling index of building produced contamination.

This paper deals with uncertainty in IAQ performance assessment of a naturally ventilated building in case of combined influence of the stochastic behaviour of both weather parameters and occupancy.

In this paper , a new index is defined to analyse effectiveness of ventilation systems with different airflow rates CFD simulations are realised with different mechanical exhaust systems in a kitchen. The coupled analysis of this new index and of the airflow rate ratio allows the analysis of the contaminant removal effectiveness while considering the energetic cost of ventilation.

This study examines the effect of building recirculation rates on the concentrations of secondary organic aerosol (SOA) resulting from reactions between indoor limonene and ozone.

For that study, an underfloor ventilation system providing two different airflow patterns (short and long throw) was tested and compared with a mixing and displacement ventilation system in a mock-up of a typical office. The systems were operated under identical conditions.
The authors conclude that an underfloor ventilation system providing a short throw can ensure both a high air quality (comparable to displacement ventilation), while providing a low risk of thermal discomfort for occupants.

HVAC systems in two hotel buildings in Pyongyang have been surveyed from 1997 to 2002 to check the effectiveness of combined mechanical cleaning and duct disinfections against microbial contamination..There were many differences of microbial contamination between the two HVAC systems during 1997-1998. respectively for bacteria and fungi in the air outlet . But they decreased from 45.9 and 28.7 cfu/m3 during 1997-1998 year to 10.3 and 4.5 cfu/m3 during 1999-2002 year

This investigation involves full-scale experiments with two breathing thermal manikins in a room ventilated by an air distribution system based on a textile terminal extended by a personalized ventilation system . The aim is to study the improved protection of people in a room..
It appears that the flow in the room is fully mixed with a limited protection of the occupants when the air is supplied from the textile terminal alone, .and the personalized ventilation improves the protection of occupants when the personal exposure index is increased.

Correlations between indoor ozone concentrations and the emission rates of oxygenated compounds are examined in this paper. Data collected in an occupied, low-polluting office at two different ventilation rates (1 h-1 and 3 h-1) with and without common indoor sources are re-analyzed reporting that with sources present the measured total emission rate was about 5% higher at the higher ventilation rate.
The results suggest that an increased outdoor-to-indoor transport of ozone gives larger emission rates of oxygenated compounds at larger ventilation rates.

Homes with natural ventilation is a predominant type of residential buildings in taiwan . As high microbial concentrations have been reported.in those buildings, the authors have studied the effects of ventilation efficiency on indoor/outdoor levels of airborne microbes in 44 homes with natural ventilation.
Indoor and outdoor airborne bacteria and fungi were collected and the air change rate (ACH) was measured by tracer gas concentration decay method.

A field campaign lasting June to October 2004 has been organized in the CSTB experimental house MARIA. It aimed at documenting the potential impact of outdoor ozone and NOx on indoor air quality, . Selected new building materials were installed in a test room where ventilation conditions are precisely controlled.Detailed experiments were performed during photochemical pollution episodes , it showed the apparition of ozone-initiated reactions products indoors.
