ST. LOUIS — Wiegmann Associates announced it has completed work on a new Leadership in Energy and Environmental Design (LEED)-certified refrigerated food distribution center for The Chefs’ Warehouse in Las Vegas. As engineer of record and mechanical and controls construction manager, Wiegmann designed and installed all refrigeration systems, HVAC equipment, and a building automation system. The new 80,000-square-foot facility features office space, a fully functional test kitchen, -10°F freezer, cooler, candy/chocolate cooler space, dry storage, and cold dock. The general contractor was ARCO Construction Co.

“The primary challenge of this project was designing and modeling the building to meet the stringent LEED standards for energy efficiency,” said Steve Pearce, vice president of business development for Wiegmann Associates. “Facilities with large process refrigeration loads use a lot of energy so we needed to design the other building systems to be extremely efficient. We also implemented energy conserving control methods for the refrigeration systems.”

Wiegmann installed refrigeration equipment for a -10° freezer, 34° cooler, and cold dock areas; a direct digital control (DDC) building automation system; a variable air volume (VAV) HVAC system to serve the 13,475-square-foot office space; a packaged rooftop unit to temper the dry storage area; and an HVAC and exhaust system for the test kitchen. Wiegmann also completed LEED documentation related to the project scope, including the energy model.
