Article Citation - WoS: 23Citation - Scopus: 30Experimental Investigation of a Decentralized Heat Recovery Ventilation System(Elsevier Ltd., 2020) Pekdoğan, Tuğçe; Tokuç, Ayça; Ezan, Mehmet Akif; Başaran, TahsinIndoor air quality is an important issue for improving and maintaining the indoor environment because it is directly related to people's health and work performance. These days, in many settlements, the applicability of natural ventilation is limited in the face of the decreasing infiltration loads, increased atmospheric pollution, and the climatic conditions. Therefore, the use of mechanical systems that are designed to ensure proper ventilation is becoming widespread. This paper presents full-scale experimental research of a wall-integrated decentralized ventilation system with heat recovery in the laboratory conditions. The heat recovery unit includes a ceramic block for sensible thermal energy storage. Parametric experimental studies were carried out to obtain the temperature distributions and the thermal capacity of the ceramic block during the supply and exhaust modes of working. In order to simulate the winter and summer conditions, two large scale temperature-controlled rooms are built up. The duration of the ventilation period is varied to be 1, 2, 5, 7.5 and 10-min. Experimental measurements indicate that 2 min of operation time shows the best thermal performance in terms of maintaining a comfortable indoor temperature with the least energy consumption. And some shortcomings were observed about the fan and thermal storage limitations. © 2020 Elsevier LtdConference Object Renovating a Lecture Hall With a Glass Roof: a Case Study of Performance Based Design(ÖKK-Editions, 2013) Atça, Emre; İlal, Mustafa Emre; Başaran, Tahsin; Kazanasmaz, Zehra Tuğçe; Durmuş Arsan, ZeynepIn practice, architects, due to time and budget constraints do not analyze designs and evaluate alternatives from the building physics perspective. They expect this analysis to be carried out by engineers. Engineers mostly get involved late in the design process, after key decisions are already finalized, leaving them powerless to solve problems efficiently. However, rapid advances both in computing and engineering have produced various simulation based tools for evaluating building performance that architects themselves can employ early in the design process. The proliferation of these tools throughout the architectural practice and education is necessary for achieving higher performance levels. In this study, the brand new Lecture Hall at Izmir Institute of Technology, Department of Mathematics that is in need of renovations to improve acoustic, visual and thermal comfort is diagnosed through measurements and the possibility of foreseeing, through simulations, the existing level of performance during the design stage is explored.
