Welcome to Big Sky ASHRAE Chapter 131

ASHRAE, founded in 1894, is a global fellowship dedicating to improving well-being through sustainable and ethical technology functional in today’s infrastructure. Our chapters across the country are focused on creating and implementing building systems, energy efficiency, indoor air quality, refrigeration and sustainability within the industry. We encourage research, continued education, standards development, and consistent publication among our members, with the goal of shaping a positive future and environment today.

Chapter 131 is made up of three sections–Billings, Great Falls, and Bozeman. We encourage networking with other industry professionals, as well as volunteering. Big Sky ASHRAE seeks and embraces collaborative efforts with organizations, agencies, and individuals sharing our commitment to sustainable built environments.
