FAQ

What are the main elements that affect heat transfer in buildings?

The main elements include walls, floors, ceilings, windows, doors, and appliances.

How does heat move in relation to temperature differentials?

Heat moves downhill relative to temperature, from hot to cold.

What are the different mechanisms of heat movement?

Heat moves through radiation, convection, and conduction.

How can heat loss in buildings be observed?

Infrared thermography and infrared cameras allow for the visualization of heat conduction and heat loss in buildings.

What are the implications of refrigerants and heat trapping devices on global warming?

Refrigerants and heat trapping devices contribute to global warming by trapping heat in the atmosphere.
