What is a cooling load?
Think about what happens when it gets too warm inside.
List two factors that affect heating load.
Consider the elements that would lower the temperature inside.
What is the primary factor contributing to cooling load?
Consider what naturally occurs during hot sunny days.
True or False: The heating load is solely dependent on external temperatures.
Reflect on what generates heat inside buildings.
A school building has an area of 3000 sq. ft., and it's located in a hot climate with a cooling factor of 30. There are 20 occupants, each contributing 300 BTU, and lighting contributes another 2000 BTU. Calculate the total cooling load.
Start by breaking down each element according to the formula you've learned.
Consider a residential building whose heating load calculation resulted in 25,000 BTU/hr based on a dynamic method. If the building has improved insulation reducing transmission losses by 20%, calculate the new heating load.
Apply the percentage reduction directly to the original heating load.
