Understanding Building Mechanical Systems

After attending this course, you will be able to:

• Describe how heating, ventilating, air-conditioning, and refrigeration systems work, and how to use HVAC&R principles to identify facility improvement opportunities
• Apply HVAC&R codes and compare equipment options
• Explain how building automation systems are critical to a successful operation
• Plan for the requirements of testing, adjusting, and balancing
• Evaluate whether total building commissioning would improve your projects
• Work more effectively with equipment manufacturers, vendors, contractors, and designers

You will have ample opportunity to interact with the instructors, discuss your challenges, and benefit from their experience.  You will gain a broad perspective on building mechanical system design and construction practices.

• Project managers
• Project engineers and architects
• Construction managers and superintendents
• Facilities managers and operations staff
• Owners’ representatives
• Owners, officers, managers, and principals of construction firms
• Equipment suppliers, vendors, and related manufacturers' technical personnel

Created for non-mechanical engineers, this course focuses on how HVAC systems work, along with practical advice for design, installation, and operation – not detailed engineering designs. This course is especially suited to those who need to work with HVAC designers or contractors on new or renovation projects, or those who maintain HVAC systems.
