Welcome to ASHRAE Connecticut Chapter!

The Connecticut Chapter is one of ASHRAE’s oldest chapters, dating back to June, 1940, when it was originally chartered as a chapter of the ASHVE. In 1959, the Connecticut Chapter of ASHVE merged with the Connecticut Valley Chapter of ASRE to become the Connecticut Chapter of ASHRAE. In 1961, the Southern Connecticut Chapter of ASHRAE also became part of the Connecticut Chapter. In 1989, a portion of the Western Massachusetts Chapter was added to the Connecticut Chapter. Today, the Chapter geographically serves the State of Connecticut (except Fairfield County) plus three counties in Massachusetts (Hampden, Hampshire, and Franklin). The Chapter has grown to be one of ASHRAE's largest with over 500 Society members.

Rich in the traditions of participation, leadership, and contribution, the Connecticut Chapter is proud of its many members who have made significant contributions to the Society and the state of the art in our industry. The Connecticut Chapter is the one of the largest out of 15 chapters in ASHRAE’s Region I. Region I is ASHRAE’s largest region, comprising nearly eleven percent of ASHRAE’s world wide membership.
