HVAC Design Calculations

Energy efficiency and sustainable design are critical components of today’s smart, green buildings. This practical course covers the fundamental calculations required for the design of building heating, ventilating, and air conditioning (HVAC) systems. Topics include cooling and heating load calculations, psychometric analysis, and HVAC energy usage.
This fast‐paced course focuses on practical methods of HVAC calculations in accordance with governing codes and American Society of Heating, Refrigerating, and Air Conditioning (ASHRAE) guidelines. Emphasis is placed upon accepted rule‐of‐thumb checks in HVAC load calculations and energy analysis, including a review of available computer programs. An optional field trip is included.

Course Highlights:

  • HVAC Heating and Cooling Load Calculations
  • Psychometric Analysis
  • Energy Analysis
  • Indoor Air Quality
  • Natural Ventilation
  • Hybrid Natural Ventilation
  • Mechanical Ventilation
  • Energy Saving Payback Analysis
  • Basics of Net-Zero Energy Buildings

Course Benefits:

  • Learn the fundamentals of psychometrics and how to perform HVAC design calculations utilizing the psychometric chart.
