Indoor environmental quality in non-residential buildings - experimental investigation

This paper presents the part of the research that has been done at the Universities both in Belgrade and Thessaloniki, Greece, taking into account indoor environmental quality in office buildings and classrooms. The measurements that are presented were done in Process Equipment Design Laboratory at Aristotle University Thessaloniki, during March 2015. Indoor environmental quality regarding air temperature, relative humidity, and CO2 concentration in two representative offices is observed. The similar offices are located one on the north-east and the other one on the south-west side of the University building, so as to be representative of the orientation's impact. Furthermore, the impact of natural ventilation on CO2 concentration and temperature is monitored, together with the offices' occupancy. Recommended parameters for indoor air quality are compared and discussed on the base of several standards: SRPS EN 15251:2010, ASHRAE standards 55 and 62.1, and ISO 7730. The main objectives, as set from these standards are discussed, together with the investigation results

Indoor Air Quality in Office Buildings – experimental investigation

This paper presents the part of the research that has been done at the Universities both in Belgrade, Serbia and Thessaloniki, Greece, taking into account indoor air quality (IAQ) in office buildings and classrooms. The measurements that are presented were done in Process Equipment Design Laboratory at Aristotle University Thessaloniki, during March 2015. IEQ, regarding air temperature, relative humidity and CO2 concentration in two representative offices is observed. The similar offices are located one on the north-east and the other one on the south-west side of the University building, so as to be representative of the orientation’s impact. Furthermore, the impact of natural ventilation on CO2 concentration and temperature is monitored, together with the offices’ occupancy. Recommended parameters for IAQ are compared and discussed on the base of several standards: SRPS EN 15251:2010, ASHRAE standards 55 and 62.1 and ISO 7730. The main objectives, as set from these standards are discussed, together with the investigation results

THE USE OF THE WEARABLE SENSORY DEVICES FOR METABOLIC RATE ESTIMATION

The human metabolic rate has been widely noted as the least accurately assessed parameter in the research of thermal comfort. Since it is difficult to measure, it is often reduced on simple diary methods which do not take into account the influence of age, gender, and daily dynamics of a building occupant. In this study wearable sensory device were used to track user activities inside the building to estimate the metabolic rate. Eight participants were chosen for the 7-days monitoring, four times during the year. The study aimed to examine whether the user age, gender, and season of the year influence the change in user metabolic rate to improve the thermal environment of the HVAC system building. The results showed the difference between groups of building occupants that could serve as a reference to assess personal thermal comfort in future research
