Any building acts as an aperture that focuses and filters sunlight inside.
Each element of the spatial programming requires different levels of illumination. As a result, sections of the Henry building structure differ by method of focusing the light in response to the distinct spatial uses inside. The goal of this study is to examine the different daylighting systems of the Henry Art Gallery Addition with focus on the relationship between the spatial lighting requirements and the amount of daylight provided. The result of the study shows that the Henry Art Gallery does integrate a high percentage of natural light into the interior environments. The evaluation of this building has demonstrated the difficulty of responding to sunlight.
