The HVAC Fundamentals module includes conceptual introductions to 5 HVAC "fundamentals" topics: 
  • Human Comfort
  • Thermal Loads
  • How an HVAC System Functions
  • Energy Conservation Opportunities (ECO’s)
  • Psychrometrics.

Human Comfort
This overview provides a summary of basic concepts including:
  • Thermal comfort concepts
  • Metabolic rate
  • How the body losses heat
  • Temperature effects on body heat loss
  • Mean Radiant Temperature (MRT)
Four of the presentations include user-interactivity, plus the MRT topic has an exercise in which the user can practice with the concepts. A quiz is provided.
Thermal Loads
This overview provides a summary of basic concepts including:
  • Internal loads
  • External loads
  • Peak loads
  • Part load conditions
  • Loads for typical office building
All topics include user-interactivity, and a quiz is provided.
How an HVAC System Functions
This overview allows the user to identify key HVAC system functions and review how the  main elements function:
  • Energy conversion
  • Distribution
  • Controls
All topics include user-interactivity, and a quiz is provided.
Energy Conservation Opportunities
This conceptual overview of ECOs shows the user:
  • 8 typical application areas for ECOs in a building
  • 3 types of ECOs
  • A recommended sequence for applying ECOs to existing buildings
This module also shows the user the structure of ECOs used throughout the HVAC Energy Primer.
