Summary: Pedestrians are at a higher risk of serious injury in vehicle collisions, especially on residential roads without dividers and with blind spots. Traditional safety features are not always effective in preventing accidents. To address this issue, a collision risk warning service using CCTVs and radar to detect objects in real-time has been proposed. User surveys conducted on university campus roads showed that the service was considered necessary and significantly contributed to traffic safety.

Summary: This article analyzes the natural ventilation of Spanish housing during the spring 2020 and finds that proper ventilation is correlated with indoor air quality and various factors including living environment, housing facilities, and family activities. The study also reveals that during the lockdown, factors such as employee status, wearing heavy clothing indoors, and window opening and closing are associated with adaptive ventilation. Hence, an appropriate natural ventilation pattern is linked to indoor air quality and environmental comfort.

Summary: The negative impact of indoor formaldehyde pollution has attracted increasing attention, particularly in severe cold areas where ventilation is insufficient and windows remain closed. A study was conducted in Liaoning, China, to explore the status and influencing factors of indoor formaldehyde pollution, as well as predict formaldehyde concentrations in these areas. Phenol reagent spectrophotometry was used to test 60 residential buildings, and the infiltration air change rate was measured using CO2 as a tracer gas. The results showed that the highest rates of formaldehyde pollution occurred in summer, with a concentration of 0.097 mg/m(3), while the bedroom had the highest concentration in autumn at 0.104 mg/m(3). The correlation analysis revealed significant associations between formaldehyde concentration and indoor temperature, years of decoration, and infiltration ventilation rate. Linear regression equations were established to predict formaldehyde concentration. According to the risk assessment, residents in Liaoning are already at risk of cancer caused by formaldehyde.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.
