I2SL's Windy City Chapter will serve as resource to the greater Chicago metropolitan area to further the Institute’s goals and promote the design, construction, and operation of resource effective and environmentally responsible facilities dedicated to education, medicine, and research. Our aim is to foster sustainable design, engineering, and operational practices through a network of industry professionals drawing upon individual and corporate expertise and real world experience. The Windy City Chapter provides advocacy and education while fostering professional interaction on industry best practices and emerging technologies that promote sustainability of laboratory and other high tech facilities. To this end, we provide an organization with a broad reach bringing expertise of architects, engineers, builders, operators, and manufacturers to create an interdisciplinary community of professionals with a comprehensive approach to the creation and operation of sustainable facilities. The Chapter stresses professional development and networking through a series of regularly scheduled meetings that provide a forum for presentations by industry experts coupled with interactive membership discussions. Check out a list of I2SL Windy City Chapter’s events.
