Columbus, Ohio / United States of America

The OSU South Campus Chiller is an iconic marker at a major campus entry. The LEED Silver building showcases energy-efficient equipment while recording the sun's energy on the exterior. Glazed openings are located to frame views of the equipment, and dichroic glass fins and boxes change color with the sun's movement, casting color-changing shadows onto modular, polished precast concrete panels.

The dichroic fins, made of laminated glass with a plastic interlayer and dichroic film, creates a color change on the façade. The fins are 3 x 5 feet, easing the fabrication and installation process. A bracket system holds the glass in place and prevents rotation.

To enhance the colors radiating from the fins, the panels are polished to a high gloss sheen and provide a maintenance free, durable surface minimizing staining and streaking. 200 panels use only 11 panel types-significantly reducing the cost by utilizing forms multiple times. Transportation of panels to the site dictated sizes to accelerate the installation; 9 x 30 feet and top panels at 35 feet enclose the cooling towers.

The result is a dynamic façade, the 'energy envelope', which changes with the time of day, season and the location of the observer.
