ASHRAE announced that Jeff Littleton will retire as Executive Vice President in early 2027. Littleton has served as the Society’s chief staff officer since 2004.
During his tenure, ASHRAE said it experienced sustained organizational growth, global expansion and increased technical impact. The Society also said it strengthened its position in building technology, sustainability and the development of critical standards for the built environment.
ASHRAE said Littleton led the organization through the COVID-19 pandemic while maintaining operational continuity. His work also included supporting ASHRAE’s selection, renovation and relocation to its net-zero energy global headquarters building in Peachtree Corners, Georgia.
“Jeff’s leadership has played a central role in navigating ASHRAE through decades of industry evolution, while advancing our global mission to serve humanity,” said 2025-26 ASHRAE President Bill McQuade, P.E., CDP, Fellow ASHRAE, LEED AP. “His steady guidance and strategic vision has helped to ensure that ASHRAE remains a trusted resource and leader in the building services industry. We are grateful for his service and the strong foundation he leaves for the future.”
The ASHRAE Board of Directors has established a selection committee to guide the search for the Society’s next Executive Vice President. ASHRAE said it will share additional details on the leadership transition in the coming months.
