Distinguished Lecturer Program

The ASHRAE Distinguished Lecturers (DL) Program began in Society Year 1996-97. The purpose of the program is to provide ASHRAE Chapters with lecturers equipped to speak on relevant subjects of interest to ASHRAE members and guests without incurring huge costs. The Distinguished Lecturer Program is supervised by the Chapter Technology Transfer Committee. For the 2017-18 Society Year, 195 visits are allocated to the 15 ASHRAE Regions. The CTTC Regional Vice Chair for each Region allocates visits to the Chapters.



Chris (Edmondson) is one of the most entertaining, enthusiastic and passionate speakers I have heard. He does a great job keeping the audience attentive and interested and communicates his messages very well. – Southern Piedmont Chapter.
