Outcome 1: Upon completion of this course, students will use tables and charts from the American Society for Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) to calculate the R-factor.


  1. Calculate window R-factors for various constructed windows for a house.
  2. Calculate door R-factors for various constructed doors for a house.
  3. Calculate various ceiling R-factors for a house.
  4. Calculate R-factors for various constructed walls of a house.
  5. Calculate R-factors for various constructed basements for a house.
  6. Calculate R-factors for various constructed cement slabs for a house.
  7. Calculate R-factors for various constructed crawl spaces for a house.

Outcome 2: Upon completion of this course, students will size heating and air conditioning equipment by calculating according to ASHRAE specifications.


  1. Calculate the heat loss for a single family detached home.
  2. Calculate the heat gain for a single family detached home.
  3. Select an appropiately sized forced air furnace for a single family detached home.
  4. Select appropriately sized cooling equipment for a single family detached home.
  5. Determine location and proper size for grills and registers.

Outcome 3: Upon completion of this course, students will complete a duct design that will be engineered, drawn to scale with proper CFM and FPM according to ACCA Manual D specifications.


  1. Determine the total airflow required for a forced air comfort system serving a single family detached home.
  2. Determine the airflow requirements for each room of a single family detached home.
  3. Use manufacturer’s literature and specifications to determine the available static pressure for a duct system design.
  4. Use duct sizing charts and design forms to calculate duct sizes
