Controlling patterns:Nobody was
at home during daytime; Heating
system was running continuously
and periodically. Room temperatures
were ranged from 18~24°C, Settings
were not adjusted actively. Not zonal
controlled and room temperatures were
varied independently. Temperature of
bedrooms were always higher than
living room.

Controlling patterns: Nobody
was staying at home at daytime;
Heating system running periodically.
Room temperatures were ranged
from 19~23°C. Not zonal controlled.
Settings were adjusted actively. Room
temperatures varied independently.
Temperature of bedroom (N) was
sometimes higher than living room or
bedroom(S).
ENG: 0.8(mean value 2), m3/(m2·month);
Pcth: 100.0% (mean value 83%);
It was clear that, differences of household controlling patterns of appliance were always neglected in the widely used centralized heating system, which deserved more attention in energy efficiency perspective. The following results could be derived from case study.
