Our Story

Over 20 Years of Inspiring Better Buildings

Group14 Engineering is an energy efficiency and sustainability consultant committed to personal, societal, and ecological prosperity. Our mission is to inspire better buildings where people thrive. Group14 brings solutions to projects throughout the United States.

While Group14’s expertise is in the built environment, our passion is the people for whom and with whom we work. We recognize that whenever we sit down at a table we have an opportunity to learn from our colleagues.

Group14 Engineering has been in business since 1992. Sue Reilly and Stephen Carpenter started the firm as Enermodal Engineering, Inc. In 2010, we changed our name to Group14 Engineering, Inc., of which Sue Reilly is the sole proprietor. In case high school chemistry didn’t quite stick, Group14 is the Carbon Group on the periodic table.
