20.500.12556/DiRROS-23489 Evaluation of various retrofitting concepts of building envelope for offices equipped with large radiant ceiling panels by dynamic simulations In order to achieve significant savings in energy and an improved level of thermal comfort in retrofitted existing buildings, specific retrofitting concepts that combine new technologies and design need to be developed and implemented. Large radiant surfaces systems are now among the most promising future technologies to be used both in retrofitted and in new low-energy buildings. These kinds of systems have been the topic of several studies dealing with thermal comfort and energy utilization, but some specific issues concerning their possible use in various concepts for retrofitting are still poorly understood. In the present paper, some results of dynamic simulations, with the transient system simulation tool (TRNSYS) model, of the retrofitted offices equipped with radiant ceiling panels are presented and thoroughly analysed. Based on a precise comparison of the results of these simulations with actual measurements in the offices, certain input data for the model were added, so that the model was consequently validated. The model was then applied to the evaluation of various concepts of building envelopes for office retrofitting. By means of dynamic simulations of indoor environment it was possible to determine the benefits and limitations of individual retrofitting concepts. Some specific parameters, which are relevant to these concepts, were also identified. radiant ceiling panels heating cooling modelling dynamic simulation retrofitting concepts paneli gretje hlajenje true false true MDPI Angleški jezik Slovenski jezik © 2015 by the authors Neznano 2025-09-05 07:30:12 2025-09-05 07:38:53 2025-10-24 03:54:26 0000-00-00 00:00:00 2015 0 0 str. 13169-13191 no. 10 Vol. 7 oct. 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2015-09-25 624 2071-1050 10.3390/su71013169 2148199 http://www.mdpi.com/2071-1050/7/10/13169 1 65e81b0c-8a19-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34741 RAZ_Jordan_Sabina_2015.pdf RAZ_Jordan_Sabina_2015.pdf 1 C35753F9B3F7C77517532969D40118F1 dd18d12476efe4c2f58df57f0ccbcbab10813aaf44830b58cd4e57b89035041c 92cf49b1-8a1a-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34744 Zavod za gradbeništvo Slovenije 0 0 0
