Nowadays, in Belgium, traffic and heating systems are the main sources of PM in cities. In Wallonia, the urban planning of the streets near schools is modified to allow area for “kiss and ride”. During school activities, dropping off the children to school slows down the traffic. A lot of parents don't turn off the motor of their vehicles for this short time. This behaviour affects negatively the air quality while children, persons at risk, are present. A PM2.5 measurement campaign on the surrounding of a school located in Arlon was realized with low-cost sensors. The sensors are fixed on the building walls, above the entrance doors. The purpose of this study was to measure the concentration of PM2.5 to which the children are exposed when they access the school. [less ▲]

Overheating is a major problem that may occur, especially in high-performing buildings. The insulation thickness that is currently installed in passive houses (around 30 cm) may indeed lead to severe overheating problems if this is some mitigated by adequate solar gains control and/or efficient ventilation schemes and strategies. This risk is expressed in percentage and calculated when the indoor temperature is above 25°C. For instance, the acceptable limit for a passive house is set at 5% over a year as defined by the Passive House Platform standard in Belgium(Vandenberghe & VanLoon, 2013). To assess overheating, dynamic simulation is a valuable approach that can be used to calculate the overheating risk and to assess the efficiency of overheating control measures. This paper presents an approach where a detailed simulation model of a passive house was developed (using TRNSYS Type 56), calibrated on the basis of measurements carried out in a typical house in Belgium and then used to compare different overheating mitigation strategies. The accuracy of the simulated model was assessed by calculating statistical indices. When the calibration results have shown a good match between measured and simulated data, the model was used in dynamic simulations to determine the best solution to reduce the risk of overheating in house under study.

Nowadays, the detection of moulds hidden in buildings is only possible after degradation of the building materials. In the early 2000s, a new approach is suggested to detect fungal contamination of building materials. This one is based on the determination of the VOC emitted by the mouds, called Microbial-VOC (MVOC). This study was conducted to screen the emission of MVOCs by three different moulds growing on specific materials (shower mat, plasterboard, wood wool). The carbon dioxide, as indicator of biological activity, was also measured. In this paper, the development of an integrated index was considered for a new approach in the detection of hidden moulds. The index will be an algorithm with various variables specific to the moulds (for example : RH, CO2, single VOC and specific VOC pattern...). The goal is to propose an innovative and simple tool working with low cost sensors. [less ▲]
