The Museum of Design Atlanta’s new exhibit is about the opposite of design for design’s sake (not that there’s anything wrong with that).

“Design for Social Impact” covers how design is being used to address 21st-century challenges. It details 24 projects by designers, engineers, students, professors, architects and social entrepreneurs in the areas of health care, education, community, shelter, food and water and energy. Atlanta groups involved include Mad Housers and Plywood People.

The opening reception is 7:30-9:30 p.m. May 29 ($30).

MODA’s Katie Simms will give curator’s tours at 6:15 and 7:15 p.m. June 5 (reservations advised).

Through Aug. 3. Noon-6 p.m. Sundays and Tuesdays-Fridays (until 8 p.m. Thursdays), 10 a.m.-6 p.m. Saturdays. 1315 Peachtree St., Atlanta. $10; $8 seniors and military; $5 ages 6-17 and students with IDs. 404-979-6455, www.museumofdesign.org/current-exhibitions.
