Energy consumption patterns are a complex technical and social phenome
non and thus to fully understand this phenomenon, it must be viewed fr
om both engineering and social science perspectives. Over the last 20-
30 years, energy research within each of these disciplines has progres
sed relatively independently, however, it is now being realized that i
n order for further development to take place these two perspectives m
ust be integrated to form a single and coherent view of energy use. Th
is paper proposes an integrated descriptive framework for energy use a
nd behaviour, based on systems theory. This framework begins to indica
te where the various models and theories from both the engineering and
social sciences relate and thus is a first step towards a more integr
ated and coherent view of energy use.
