Abstract
In this study, based on the current daylighting situation of a museum sculpture exhibition hall, the exhibition space is classified according to the daylighting requirements of the sculptures. Additionally, the daylighting pattern for the sculpture exhibition hall and the display layout of the exhibits are summarized. The daylighting parameters of the exhibition space under different scenarios are calculated. The exhibition space is simulated and analyzed under three daylighting conditions (flat skylights, flat skylights with side windows, and flat skylights with high side windows), and the daylighting parameters are optimized based on the daylighting patterns and components. It is discovered that with the combination of flat skylights and high side windows, the daylight factor (DF) and uniformity of daylighting (UD) of the sculpture exhibition as well as glare rating of the windows are the most favorable. Therefore, the appropriate daylighting pattern and components are determined, and the corresponding optimization strategy for daylighting is proposed. The results show that the daylighting optimization strategy proposed herein can improve the daylighting quality of the museum sculpture exhibition space and yield a suitable light environment.
Highlights
A sculpture exhibition hall is an exhibition space for all types of sculptures
One should first understand the relationship between the daylighting design methods and the museum’s natural light [1] to yield a reasonable daylighting design based on the actual light environment
The high side window installed on the north wall of the exhibition hall in the original scheme is maintained in size but folded in half such that it becomes a L-shaped component, where half of it remains as the high side window, and the other half becomes a flat skylight
Summary
A sculpture exhibition hall is an exhibition space for all types of sculptures. Such exhibits impose unique requirements for their three-dimensional perception, as their exhibition effect depends significantly on the quality of the architectural light environment design. As large-sized windows for daylight in museum buildings generally result in direct glare in the visual field, reasonably sized windows for daylight must be adjusted to ensure light comfort in the exhibition hall and reduce the effects of glare in specific areas [19]. Improper design or lack of effective methods for controlling natural light might result in excessively high illuminance and poor uniformity of daylighting (UD) at certain areas of the indoor space, resulting in both direct and reflected glare in the viewers’ visual field and degrading people’s viewing experience. To avoid the improper design of the light environment for a sculpture exhibition hall, reasons of glare caused by daylighting were analyzed, and factors affecting the daylighting quality of the sculpture exhibition hall were investigated. The daylighting design of a sculpture exhibition hall was optimized from the perspective of adjusting daylighting parameters
