Solar Shift is a proposal for an exterior art piece for the new Evansville Arena. Design by PROJECTiONE LLC, the structure looks at the large public outdoor space in combination with concepts of sustainable interactive lighting. The project will dynamically change in response to individuals and groups in the space through the use of motion sensors, photovoltaics, and LED lighting.
Solar Shift is created as a fully self contained system that acts as a solar collector, using photovoltaic panels to charge during the day, and in turn power the reactive lighting in the evening. As the sun sets each day, the project shifts and slowly comes to life, recognizing the individuals inhabiting it and lighting up to follow their movement in space. Each component in the system will power itself and react independently, eliminating any electrical connections between panels or tapping into an existing power grid.
Formally, Solar Shift derives its shape from the sun path data of Evansville, Indiana. We began by digitally 3d modeling a surface that is optimized for ideal solar radiation throughout the year from 9:00 am to 3:00 pm. From there, the form was modified to accommodate access to the site, circulation paths, and visual aesthetics. We then utilized parametric design software to divide the surface into a triangular component system, where each panel relates to the original sun path data.
