Energy use in the Japanese residential sector has more than doubled (o
n a per-household basis) during the post-war period. Important factors
contributing to the increase include changes in the types of housing
built, heating, cooling, water-heating equipment, and other appliances
. In this paper, the developments of household equipment and living co
nditions in Japan are described, from their 1950s state to the present
. Trends in energy consumption by fuel types and end uses are reviewed
over the same period. The past trends are combined with expectations
for future developments in household equipment and quality, as well as
with international comparisons of household-energy use, to predict fu
rther increases in household-energy consumption. The results indicate
the importance of a renewed emphasis on energy efficiency in the resid
ential sector. Copyright (C) 1996 Elsevier Science Ltd.
