We performed the first large-scale investigation of indoor air quality (IAQ), energy and occupant behavior satisfaction, in 650 energy-efficient dwellings western Switzerland. The included comparative assessment 217 green-certified Minergie (M) 433 energy-renovated (R) dwellings. Data were collected through a combination questionnaire survey building characteristics occupancy symptoms/satisfaction, as well field measurements radon, total volatile organic compounds (TVOC), formaldehyde fungi....
Radon is a naturally occurring radioactive gas that has the potential to accumulate in buildings and over time, causes lung cancer humans. Present methods for radon measurements are disparate, which pose challenges benchmark concentrations accurately assess population's received dose. This paper presents comprehensive performance evaluation of dosimeters three grades active sensors: consumer-, medium- research-grade. The were performed at relatively low (300 Bq/m3) high (2′000–3′000 levels....
Exposure to elevated levels of certain volatile organic compounds (VOCs) in households has been linked deleterious health effects. This study presents the first large-scale investigation VOC 169 energy-efficient dwellings Switzerland. Through a combination physical measurements and questionnaire surveys, we investigated influence diverse building characteristics on indoor VOCs. Among 74 detected compounds, carbonyls, alkanes, alkenes were most abundant. Median concentration formaldehyde (14...
Radon is a natural and radioactive gas that can accumulate in indoor environments. Indoor radon concentration (IRC) influenced, among other factors, by meteorology, which the subject of this paper. Weather parameters impact levels have already been investigated, but rarely Switzerland. Moreover, there strong need for better understanding behaviour inside buildings Switzerland public health concerns as prone area. Based on long-term, continuous, hourly measurements, distributions classified...
As part of more stringent energy targets in Switzerland, we witness the appearance new green-certified dwellings while many existing have undergone efficiency measures. These measures led to reduced consumption, but rarely consider their impact on indoor air quality. Consequently, such renovation actions can lead an accumulation radon located radon-prone areas at doses that affect human health. This study compared levels over 650 energy-efficient western Switzerland between (Minergie) and...
The presence of growing fungi in the indoor environment has been associated with development respiratory problems such as asthma or allergic rhinitis, well worsening pathologies. Their proliferation indoors could be a result water leakage inadequate ventilation. Although factors promoting mould growth have widely investigated traditional dwellings, little work done energy efficient dwellings. Here, effectiveness ventilation type, i.e., natural mechanical, influencing was estimated 44 recent...
Radon is a natural and radioactively well-known carcinogenic indoor air pollutant. Since 2020, radon short-term proactive methodology has been proposed by Swiss authorities, which aims to evaluate the probability of overpassing national reference value. This study assess influence different weather parameters on levels monitored using this methodology. To end, statistical tools are used, such as correlations, auto-correlations, cross-correlations, multiple linear regressions between...
Radon, a naturally occurring radioactive gas, poses significant health risk by accumulating in buildings and potentially leading to lung cancer. Depending on building construction geographical location, radon levels can vary substantially both within individual between different buildings. While previous studies have primarily focused the impact of temperature relative humidity devices, influence aerosols remains largely unexplored. This paper presents comprehensive evaluation indoor aerosol...
Humanitarian tents provide emergency shelter for people displaced by conflict and disaster in diverse climatic conditions. This article compares the thermal performance of two standard humanitarian – Standard Family Tent (SFT) Geodesic (GFT). The SFT is most widely used shelter, while GFT was recently introduced as a potential replacement intended to provide, inter-alia, improved performance. study aims assess extent which this intention achieved and, doing so, improve understanding about...
As part of the European RadoNorm research project, citizen science pilot projects focusing on management radon risk in houses have been implemented four countries. This article describes methodological basis, development and results French project. Building an initial review existing literature, project aims to frame a 'participatory approach' aligned with standards recognized practices science. Particular attention was given data inclusion ethical considerations. The focal point process...
Abstract Radon is a natural radioactive gas that may cumulate in indoor environments. The impacts of weather events on radon concentration had been explored different places around the world but only marginally Switzerland. Using basic statistical analysis, this study investigates meteorological parameters’ influence concentrations and shows outdoor air temperature most influential beyond others. Finally, paper highlights importance dynamic buildings, topic often overlooked by construction...

Abstract The Scol’air-FR project is issued from the need to establish an inventory of indoor air quality conditions in primary schools canton Fribourg, Switzerland. In official trend promote mechanical ventilation systems ensure a good quality. A properly designed, built, commissioned, and operated system should be able deliver anticipated flow rate, regardless who uses it - only person involved being responsible for operation. some cases, however, expected objectives are not achieved. This...
Abstract Radon is a noble, natural, and radioactive gas coming mainly from the ground which might accumulate indoors lead each year to 200-300 deaths lung cancer in Switzerland. A brand new innovative living lab will be built as of 2023 Fribourg (Switzerland) allow tackle environment relationship with its occupants. Among large panel environmental parameters, radon continuously monitored under around building well envelope. This paper aims present overall process dataflow: 1) design sensor...
