Heat transfer:
Heat transfer boils down to the two laws of thermodynamics, which is an area of science that looks at the
relationship between heat and other kinds of energy.
1. The first law of thermodynamics – Law of
conservation of energy – states:
• Energy cannot be created or destroyed
• Energy moves from place to place
• Energy changes from one form to another
Conduction
• transfer of heat between
objects that are in contact.
2. The second law of thermodynamics states:
• Heat moves from warmer to cooler
• Air moves from higher pressure to lower
pressure
• Moisture moves from wetter to drier
Radiation
 transfer of heat from a warm
object through space to a
cooler object.
 The two objects do not have to
be touching for successful heat
transfer.
Convection
 transfer of heat by the
circulation of a liquid or gas.
This type of heat transfer
requires a fluid medium, such as
air or water.
EARTHSHIPS: ENERGY EFFICIENT, SELF-SUSTAINING HOMES
ENERGY FORMS, TRANSFER, AND TRANSFORMATION USED IN SUSTAINABLE BUILDING DESIGN
Whilst watching this video be sure to take notes in the table on page 1 or in your workbook,
analysing the building design of the Earthships in terms of both energy transfer (object to
object) and energy transformation (form to form).
1) Identify the sources of heat energy and the different types of heat transfer utilised in the in
the Earthship design? How are they utilised?
2) Identify the sources of light energy utilised in the Earthship design? How are they utilised?
3) Identify the sources of movement kinetic energy utilised in the Earthship design? How are
they utilised?
4) Identify the sources of stored/potential energy that are utilised in the Earthship design?
How are they utilised?
