Japan's first appliance energy efficiency standards were set in 1979 u
nder the Energy Conservation Law and covered refrigerators and househo
ld air conditioners. In 1994 a number of appliances were added to the
list of specified equipment. After explaining the process by which sta
ndards are established, we review the new standards for fluorescent li
ghts, televisions, heat pump air conditioners, and copiers. The new st
andards are expected to exert a major influence on appliance efficienc
ies in Japan, reversing a decade-long trend of designers ignoring ener
gy efficiency. Manufacturers will shift their product mix away from in
efficient models. (C) 1997 Elsevier Science S.A.
