Evaluating the impact of air cleaning on bioaerosols and other IAQ indicators in Belgian daycare facilities | 2023 | English | 10 pp
The scientific community has been aware of the importance of indoor air quality (IAQ) for many decades, but the COVID-19 pandemic has brought a significantly higher level of attention from the general public and governmental entities to this theme
Developing methodology for testing of gas-phase air cleaners based on perceived air quality | 2023 | English | 3 pp
The existing standards for testing gas-phase air cleaners are based on challenging them with gaseous substances.
Evaluation of sensor-based air cleaners to remove PM2.5 and TVOC from indoors with pollutant sources of smoking and burning candles | 2023 | English | 10 pp

Thermal comfort and risk of draught with natural ventilation - assessment methods, experiences and solutions | 2023 | English | 10 pp
The majority of research and hence the assessment methods and tools for thermal comfort assessment of ventilation systems are not based on findings for natural ventilation solutions and do not take into account the specific characteristics of natu
Distribution of Particulate Matter Concentration and Temperature Stratification Examined by Zonal Model and Experimental Measurements in Room with A Novel Portable Displacement Ventilation Cooling Unit | 2023 | English | 10 pp
This study introduces a novel conceptual design of a mobile DV cooling unit that is aimed to support the ventilation and reinforce the thermal stratification in DV rooms.
Naturally ventilated (NV) buildings, when well designed and operated, can provide adequate indoor environmental quality (IEQ) while reducing the building energy demand.
A survey of building design practitioner perceptions of ventilative cooling in their building design processes | 2023 | English | 10 pp
Buildings account for 40% of EU energy consumption and 36% of the energy related greenhouse gas emissions at present.
Ventilation reliability: A pilot study on window opening behaviour in a primary school | 2023 | English | 16 pp
Most New Zealand schools are designed to be naturally ventilated, using openable windows (Ministry of Education Design Quality Standard Guidelines). Furthermore, they must meet the New Zealand Building Code Clause G4 - Ventilation.
A methodology for evaluating the ventilative cooling potential in early-stage building design | 2023 | English | 12 pp
As a result of the new initiatives and regulations towards nearly zero energy buildings, designers are more frequently exploiting the cooling potential of the climate to reduce overheating and improve indoor well-being of people.
A detailed investigation of the impact of an innovative dynamic façade system on indoor environmental quality in offices | 2023 | English | 9 pp
In recent years, naturally ventilated glass façades have become a common feature in the design and retrofit of large-scale non-residential buildings, integrating architectural aesthetics and energy efficiency.
Impact of optimized residential ventilation with energy recovery on health and well-being | 2023 | English | 10 pp
With rising insulation standards and air tightness in buildings, the use of mechanical ventilation becomes more relevant. In this context, energy recovery offers a significant contribution to the decarbonisation of building operations.

Applicability and sensitivity of the TAIL rating scheme using data from the French national school survey | 2023 | English | 9 pp
The TAIL rating scheme for assessing the quality of Thermal, Acoustic, Indoor air, Luminous, and the overall environment was initially developed to assess indoor environmental quality (IEQ) in hotels and offices.
We sleep more than twenty years during our lives. Sleep is essential for physical and psychological health. Yet, nearly no standards define indoor environmental quality conditions for optimal sleep.
The main focus of this paper can be summarized in terms of the following two presuppositions: i) The process through which we select and apply indoor-environmental quality (IEQ) constructs could be – perhaps should be – improved; ii) Such improvem
