As a defining factor in shaping people’s experience in architectural spaces, lighting is realistically visualized via a plethora of rendering options in CAD and BIM solutions. However, their outputs are usually static or limited to basic changes. Thus, they may not satisfactorily visualize many dynamic and interactive lighting scenarios, such as energy-saving smart windows and lights, engaging street illumination, and entertainment setups. With the increasing automation of human-building interaction (HBI), visualizing such interactions empowers researchers and students who are interested in experimenting with customized lighting setups. Moving in this direction, this paper presents the lighting features of Tames, an open-source Unity toolkit developed by the author that visualizes dynamic and interactive elements in virtual environments without a need for programming. With Tames, the designers can navigate and interact with the design from the perspective of an occupant with the lighting and other elements in real-time manually or automatically. The workflow and capabilities of Tames are demonstrated by its application in the context of concert hall project designed by a student. This author argues that the availability and user-friendliness of this tool will contribute to architectural pedagogy and research. It allows students and researchers to visualize a wider variety of interactive designs and cases easier and, as an enabling tool, it may encourage them to explore and experiment with dynamic and interactive lighting.
