Meeting/Event Information

Illinois Chapter usually meets once each month, August through June, on Tuesdays. The Chapter’s annual golf outing and fund raiser always takes place in September. Generally 70 to 80 members gather at monthly meetings, which makes them an excellent networking opportunity for members interested in meeting and developing other contacts in the industry.

The State of Illinois requires professional engineers to complete 30 PDHs (Professional Development Hours) of training for license renewal. The Illinois Chapter ASHRAE offers educational programs with more than enough PDHs to help engineers satisfy this requirement.

Presentations from previous Chapter seminars and meetings may be downloaded after logging into the "Member Area." The Illinois Chapter of ASHRAE stores past presentations. You must be a member to access them from this website. If you are not yet a member, sign-up today or contact us for more information.

Haymarket Pub and Brewery
737 W. Randolph Street
Chicago, IL 60661

Ever since the Montreal Protocol meetings began regulating CFCs in the 1980s, refrigerant rules and acceptability continue to evolve. Since then, there has been an increased focus and accelerated timing on regulations for all fluids that are being used today in the HVAC industry. This persistent churn generates confusion — what's in, what's out, and what's coming? At the same time, the market has been demanding equipment, design strategies and control methods that result in the highest levels of efficiency — will the new fluids hinder or enhance that efficiency? The next-generation of fluids represents new challenges for providing the highest performing HVAC equipment; besides efficiency they may also challenge the industry’s expectations for safety and flammability. This presentation explores the rapidly changing regulatory landscape, and discusses why, when, and how the industry will face the coming refrigerant transitions.

Our presenter, Michael Patterson, Trane Chiller Product Manager, works closely with product planning, product support, engineering, manufacturing, and other groups focused on continuing the growth of Trane’s centrifugal portfolio. Before joining Trane in 2007, he was a Strategic Chiller Systems Engineer with the Applied Chiller Systems Team supporting customers throughout North America, Europe and the Middle East. Mike is a member of ASHRAE, a non-voting member of SSPC 90.1 Energy Efficient Design of New Buildings and a voting member on the ECB Sub-Committee. He holds a Bachelor of Science degree in Engineering Mechanics from the United States Air Force Academy and a Masters in Business Administration from Regis University.

This presentation should qualify for up to 2 PDHs. Members and guests are invited. Please register in advance online or call the Illinois Chapter office, 708-636.5819.

The Haymarket Pub and Brewery is located at the corners of Randolph and Halsted Streets in the northwest Loop area, accessible from both CTA and Metra trains and buses. Some street parking may be found on streets parallel to Halsted, to the west. There is also a paid parking lot a block away at Halsted and Lake Streets.
