Milwaukee Public Market

Architects for the Milwaukee Public Market in Wisconsin used about 8,150 square feet of exterior glass to illuminate the shopping areas with natural daylight.

Maximizing transparency, however, made controlling solar heat gain and ultraviolet light critical in the food market setting, says project architect Paul Rushing, associate for Kubala Washatko Architects Inc. in Cedarburg, Wis.

“We had the fresh produce, chocolates and fish that cannot be in hot sunlight, but we wanted the daylight,” Rushing says. “So we relied heavily on low-emissivity glass and horizontal shading louvers.”

Architects specified 1-inch insulating units with Pittsburgh-based PPG Industries’ Sungate low-e glass. Oldcastle Glass of Santa Monica, Calif., fabricated the glass.

To limit direct sunlight, architects used an extruded aluminum louver system with horizontal veins. Through computer modeling, they calculated the number and placement of the sunshades that would best control light and heat, Rushing says.
“We modeled the building virtually and experimented with a number of shades and dimensions to ensure that during critical hours we could block solar heat gain,” Rushing says. “It was a balance between putting as much glass as we could on the building to get daylight and having louvers that did not project too far out.”

Intertec, a division of Doralco, Alsip, Ill., supplied three custom aluminum sunshades for the project: one with 8-inch aluminum air foil blades and two with 6-inch wall aluminum air foils. A total of 80 shades were used on the building. All used a clear anodized finish.

CG Schmidt Construction of Milwaukee served as the general contractor, and National Glass Solutions & Energy Saving Windows of Muskego, Wis., as the glazing contractor. Efco Corp. of Monnett, Mo., supplied the curtain-wall system.
The $7.5 million market opened in October 2005.
