D. Effort to save energy by workers

15

However, in order to achieve ZEB, ” Human Factor” is a key.

Education and making rules are important and cost effective.

• Paper-less work

style

• Setting of the room

temperature at

28℃

• Effort not to use

wasting energy

• Tele-conference /

TV conference

・・・

Another case shows 70% CO2 reduction by

technologies and the rest 30% by human factor.
