Understanding thermal conduction and building heat loss

Principles of energy • Conservation and dissipation of energy

Key concepts

What you'll likely be quizzed about

  • Thermal conduction is the transfer of heat energy through a material without any movement of the material itself.
  • It occurs when molecules in a material collide and transfer energy to adjacent molecules, resulting in a gradual increase in temperature from the hot region to the cold region.
  • This process is governed by the temperature difference between the interacting molecules.

What is the impact of thermal conductivity on energy bills?

Click to reveal answer

Lower thermal conductivity materials decrease heat loss, leading to lower energy consumption and reduced bills.

Key notes

Important points to keep in mind

Lower thermal conductivity leads to less heat loss.

Insulation materials are critical for energy efficiency.

Heat loss occurs through conduction, convection, and radiation.

Thermal bridges can significantly increase heat loss.

Double glazing reduces loss of heat due to conduction.
