Technical Session - 5 pm (optional) - Hydronics 101.  By Jeff Boldt.

Dinner - 6:15 pm

Main Presentation - 7:00 pm - Understanding ASHRAE Standard 188 and Engineering Keys to Legionella Control.  By Jeff Boldt.

Technical Session Highlights:

Jeff Boldt will cover Hydronics 101.  This presentation focuses solely on the basics related to configuration, layout, and major system components of hot water and chilled water systems as an introduction to hydronics for those new to the design industry.

Main Presentation Highlights:

Legionella is a waterborne pathogen that accounts for numerous deaths each year. Legionella species are among the pathogens that are a concern for facilities in potable and cooling water systems. While many guidelines exist to assist with reducing Legionellosis risk, incorporating these recommendations into building specifications at the design stage is not always straightforward and is often overlooked. This seminar provides an overview of Legionella (the bacteria and the disease) and provides guidance to engineers on how to specify system design using existing guidelines and codes.


  1. Understand the challenges of Legionnaires' disease prevention and control of Legionella in water systems
  2. Know current trends in epidemiology (disease transmission), diagnosis and treatment of Legionnaries' disease
  3. Distinguish and be familiar with Legionella disinfection and control methods, including chemical and non-chemical methods
  4. Apply the information from this seminar to write specifications for water treatment in cooling water systems
