Heat is lost from buildings, furnances and heat stores. Reducing this heat loss reduces the waste and therefore increases efficiency.
Thermal insulation:
The thicker the materials, the lower the thermal conductivty the lower the rate of heat loss. Each additional layer however reduces the efficiency and is less protective than the previous one.
Volume:
The heat energy is lost through the external layer. As the surface area to volume ratio increases the more heat is loss. We need a small surface area large volume.
When investigating we need to looks at material, 3D shape, colour, darkness and experimental conditions such as room temperature. All must be standardised before invetigated.
