5.2. Heating Load Considerations

Try these first

1. 1.

   List two components that contribute to heating load.

   Hint

   Think of the building structure.

2. 2.

   What standard is used for residential heating load calculations?

   Hint

   Focus on residential applications.

3. 3.

   What method is primarily used for estimating heating load in residential buildings?

   • ACCA Manual J
   • ASHRAE Standard 62.1
   • ACCA Manual N

   Hint

   Think about which standard pertains specifically to homes.

4. 4.

   True or False: Dynamic analysis assumes steady conditions over time.

   • True
   • False

   Hint

   Focus on what is meant by 'dynamic' versus 'steady.'

5. 5.

   A building has an external wall area of 800 sq. ft. that loses 2 BTU/hr per sq. ft. to the outside. It has 200 sq. ft. of window area losing 5 BTU/hr per sq. ft. Calculate the total heating load.

   Hint

   Calculate heating losses from walls and windows separately before combining.

6. 6.

   If a building with both solar gains and internal loads has excessive heating needs, what strategies can be implemented to optimize heating load? Discuss your approach.

   Hint

   Think about passive and active solutions for energy efficiency.
