Introduction:

Understanding codes & regulations governing design, maintenance & operation of HVAC Equipment and Systems is a must for all individuals who have interest in and working with HVAC systems. Proper design and operation of HVAC Equipment and Systems not only requires a thorough understanding of relevant codes and standards, but also it requires one to stay up-to-date with all frequent changes introduced in these codes and standards. This course focuses on enabling participants to be knowledgeable with heating, ventilation and air conditioning systems with respect to requirements of Environmental Separation and Heating, Ventilation and Air Conditioning of the Provincial Building Code. The course also covers information on applicable standards referenced in these codes such as ASHRAE standards 55, 62.1, & 90.1. Case studies and workshops will be used to explore the prescriptive compliance options and the performance compliance options available in these codes and standards. Recent changes introduced in these codes & standards and their implications on the design & operation of HVAC Equipment and Systems will also be addressed. The course will feature:

• Psychrometric representation and analysis of commonly used HVAC cycles
• Overview of various HVAC systems
• Building code sections pertain to HVAC systems
• Codes and standards applicable for design and operation of HVAC systems
• ASHRAE standard 55 - thermal environmental conditions for human occupancy
• ASHRAE standard 62.1 - ventilation for acceptable indoor air quality
• ASHRAE standard 90.1 - energy standard for buildings except low-rise residential buildings

Course Objectives:

By the end of this course, delegates will be able to:

• Identify & understand recent changes introduced in the codes/standards & their implications on the design & operation of HVAC equipment & systems
• Plan & design HVAC equipment & systems in compliance with applicable codes & standards
• Identify & Select procedures for efficient operation of various HVAC equipment & systems
• Understand which compliance option is most suitable for a given circumstance
• Identify regulations which pertain to your own specific situation
• Gain insight into how to modify/adjust current systems in order to comply
