“…However, Sinnott and Dyer highlighted the importance of workmanship and construction detailing in order to achieve the required air tightness [17]. In the case of new buildings, the improved air tightness of the envelope may lead to the increase of carbon dioxide concentration and humidity content of the indoor air [18]. Low ventilation rates in dwellings increase the risk of allergic symptoms among children [19].…”

Using personalized ventilation systems in office buildings, important energy saving might be obtained, which may improve the indoor air quality and thermal comfort sensation of occupants at the same time. In this paper, the operation testing results of an advanced personalized ventilation system are presented. Eleven different air terminal devices were analyzed. Based on the obtained air velocities and turbulence intensities, one was chosen to perform thermal comfort experiments with subjects. It was shown that, in the case of elevated indoor temperatures, the thermal comfort sensation can be improved considerably. A series of measurements were carried out in order to determine the background noise level and the noise generated by the personalized ventilation system. It was shown that further developments of the air distribution system are needed.

“…In case of free-running office or educational buildings with large glazed areas, extreme high indoor temperatures may appear [8,9]. In case of new buildings, the improved air tightness of the envelope may lead to the increase of carbon dioxide concentration and humidity of the indoor air [10]. Complex studies have to be performed in order to choose the appropriate ventilation strategy [11].…”

Energy saving is one of the most important research directions in the building sector. Personalized ventilation systems are energy conscious solutions providing fresh air for the occupants. As a side effect, cooling energy can be saved due to higher convective heat removal. Using the data gathered from previous experiments performed with the developed personalized ventilation system, a ±1.408 °C accurate simulation model was created in ANSYS 19.2 Academic version in order to determine the temperature distribution on the face. In this paper, the method and the first results are presented. It was clearly demonstrated by measurements and simulations that the personalized ventilation equipment used has a considerable effect on the skin temperature of the face. The developed model can be used to analyze the skin temperature on the faces of people using the novel, personalized ventilation equipment. This way the time spent on examination can be reduced considerably.

“…Different activities generate moisture indoors. These include moisture generation from occupants due to respiratory process, bathing or showering, cooking, dish-washing, laundry, and drying (Zemitis et al, 2016). On the other hand, indoor moisture can be removed by ventilation and dehumidification processes.…”

This study focuses on analyzing temperature-and moisture-related parameters based on data from 45 Finnish and 20 Lithuanian multi-family buildings. The data consist of two rounds of 2-month data-logging (1-h interval) of indoor temperature and relative humidity at two locations: one representing average occupied zone and the other one nearby the coldest spot of the building envelope. Between the two rounds of data-logging, 37 buildings from Finland and 15 buildings from Lithuania underwent retrofits, aiming to improve their energy efficiency. Measurement data were coupled with outdoor data from national weather stations, based on which a temperature factor (f c) and excess indoor moisture content (Dv) were calculated. Based on the results, f c was significantly higher in Lithuanian case buildings after the retrofits, whereas no significant differences were observed in Finnish buildings. In addition, Dv was significantly lower in Finnish case buildings after retrofits, whereas an opposite trend was seen in the Lithuanian buildings.
