The use of radiant systems for cooling purposes in buildings is attracting considerable attention, particularly for Suspended Radiant Ceiling Panels (SRCPs). However, the arrangement of the panels on the ceiling and the influence on radiative heat transfer is rarely discussed in the literature. The objective of this paper is to provide a numerical study of the radiative heat transfer at room scale when the size and the number of SRCPs varies. It has been observed that the use of a single large panel would result in a low average temperature, which is desirable, but also in poor uniformity of the temperature field. Here, a genetic algorithm is proposed and tuned to determine the positions of multiple SRCPs that would improve uniformity. It is shown that much better uniformity can be obtained, with only a moderate increase in the average temperature, for 10 panels or more. The differences between the use of a single large panel and multiple panels is noteworthy when SRCPs cover from 10 to 70% of the ceiling area.

“…However, both papers have not studied the impacts of heat sources on other objects. Arslanoglu [18] investigated the effect of radiation heat flux from lights lamps on human thermal comfort by both experimental and theoretical approaches. In addition, Kalmár [19] found that mean radiant temperature has a parabolic variation with the room height and length, therefore for a room shape there is a certain height for which the mean radiant temperature is minimum.…”

Abstract:Energy performance of buildings has attracted much attention among building physicists and engineers worldwide. The effects of building heating; ventilation; and air conditioning (HVAC) systems' design upgrade on the building energy performance are the focus of the current study. The adopted HVAC system consisted of chilled ceiling and chilled beam systems served by a centrifugal water chiller. An energy simulation study was undertaken in accordance with the national Australian built environment rating system-rules for collecting and using data. A three-dimensional simulation study was carried out utilizing the virtual environment-integrated environmental solutions software. Results from the current study have shown the importance of utilizing energy-efficient HVAC systems and HVAC strategies for achieving a high building energy star rating. Recommended strategies in order to achieve the nominated star rating; as predicted by the simulation analysis; were presented. Moreover; the effects of solar radiation inside the building atrium were significant; which cannot be overcome by simply installing a low shading coefficient glazing type at the atrium skylight. In addition to providing chilled ceiling technology; a high efficiency chiller and low energy lighting; it is recommended that the building be well tuned during the commissioning period. The current approach could be extended to accommodate higher energy ratings of commercial buildings at different locations worldwide.
