【 摘 要 】

The aim of the study is to evaluate the potential of enhancing thermal comfort and energy consumption created by three different radiant systems in the newly-built Energetikum office building. A representative office, Simulation room 1/1, was selected from 6 areas equipped with portable sensor groups for the indoor environment monitoring. The presented data obtained from 3 reference weeks; the heating, transition and cooling periods indicate overheating, particularly during the heating and transition period. The values of the indoor air temperature during the heating and transition period could not meet the normative criteria according to standard EN 152512007 (cat. II.) for 15-30% of the time intervals evaluated. Consequently, a simulation model of the selected office was created and points to the possibilities of improving the control system, which can lead to an elimination of the problem with overheating. Three different radiant systems - floor heating/ cooling, a thermally active ceiling, and a near-surface thermally active ceiling were implemented in the model. A comparison of their effects on thermal comfort and energy consumption is presented in the paper.
