The energy use of commercial building operations is a significant contributor to the total global energy demand, and lighting is one of the largest end uses of electricity in commercial buildings. Convention Centers as commercial buildings are examples of big energy consumers, and they present a unique opportunity to showcase benefits of green building techniques due to their large size and broad range of visitors; however, the individual nature of convention centers makes it challenging to find design improvements which will be helpful in general for many convention centers. One exception to this rule of individuality is the presence of public assembly rooms, which are ubiquitous in nature and are used heavily.
Traditionally, public assembly rooms are fully enclosed to allow for full control of illumination levels with artificial lighting, particularly fluorescent light. This represents a missing opportunity to utilize daylight or energy efficient artificial light to reduce energy use while enhancing human visual comfort.
The objective of this research is to analyze the potential impact of the use of daylight in public assembly rooms. We present the results of a set of computer simulations performed using IES VE software. The simulations are performed as an iterative process, using as base case a north-facing public assembly room in the Tucson Convention Center, and progressively updating the lighting scheme using the software to analyze the illuminance levels for each case. The results are used to propose a lighting scheme for the north-facing public assembly room which uses 100% daylight to achieve a uniform level of illumination and meets the compliance of illumination requirements for public assembly rooms.
