In this edition of the Carnegie Mellon Architecture Newsletter, we explore the legacy of the Center for Building Performance and Diagnostics, one of the most storied research centers at the school. We hear from co-directors Vivian Loftness, Erica Cochran Hameen and Azadeh O. Sawyer, as well as an alum of the program, Siliang Lu (PhD-BPD '19). We also learn about research from the M.Arch Travel Awards winners, who presented their work at an exhibition and Pecha Kucha presentation on October 27.
