Environmental odour management today offers a variety of building blocks, ranging from the use of state-of-the-art technology to the implementation of various methods, which are based on national and international guidelines and standards. These range from odour monitoring approaches using trained human sensory panels and citizen science, real-time and forecasted dynamic dispersion modelling, trajectory and back-tracking calculations, but also sensor systems which are making use of gas sensors to detect and quantify key odorants of odour sources.

   Although all of these technologies and methods can help to increase the understanding of potential origins of odour related problems, most solutions available in the market only allow an isolated consideration of the acquired data. Depending on the specific scenario and related questions, however, the right combination of these building blocks is often key to get full clarity on the odour emission and / or impact situation. A flexible platform like Ortelium allows to combine data channels, so that a more meaningful picture of the odour situation can be established.

   Indoor air pollution is one of the biggest concerns in terms of public health. In France, it was estimated that indoor air pollution would bring about a socio-economic cost of around 20 billion euros per year. In this context, the treatment of this kind of pollution has become an important challenge.

   The CUBAIR project aimed to develop and evaluate an original prototype, combining air purification techniques such as adsorption, filtration and photocatalysis. The evaluation of the performance of this prototype was carried out in situ during 10 months and different measurements were taken for parameters and pollutants such as nitrogen oxides and VOCs with emphasis on BTEX and some aldehydes. Other measurement campaigns were carried out to determine particle concentrations (PM₁, PM_2.5, PM₁₀), microbiological parameters, comfort parameters (temperature, relative humidity), as well as the air flow of the prototype. The results show a good removal efficiency (RE) of nitrogen oxides with a RE of 86% for the NO₂. Likewise, PM₁ was reduced by more than 75%.
