Concrete’s sustainability and versatility are showcased in The Refinery—a 45,000-square-foot, two-story building on the Saddleback Church campus. It includes dining and kitchen facilities, a theater, game rooms, an 800-seat auditorium, a full-court basketball gymnasium, and classrooms.

Recycled materials, including concrete, steel, wall framing, and wall board, were used as much as possible throughout the building; 4000 cubic yards of concrete were placed during construction. Ninety-five percent of the construction waste was recycled.

About one-half of the interior concrete slabs were stained and polished. Also adding to the project’s sustainability was extensive use of polished concrete countertops. Concrete’s low maintenance needs is another sustainable benefit.

The Refinery will use 40% less water and consume 35% less energy than most buildings its size in California.
