“Green Curtain Project” Operation Report 2007 by the Hitachi Chemical Group

The Hitachi Chemical Group has operated an employee participation program called the “Green Curtain Project” (a campaign to promote the use of "green curtains" of vegetation) as part of its “Team -6 %” program, a national campaign geared to reduce global warming, since last year.

The “green curtain” refers to preventing indoor temperature rise by cutting direct sunlight and utilizing the transpiration from leaves using curtain-like vines to cover windows and walls of buildings. This allows a reduction in the use of air conditioners. The scheme was run at seven Hitachi Chemical group sites in 2006, then expanding it to the whole group, then it was done at a total of nine company sites this year, including two sites newly participated.

According to energy conservation calculations, the Hikone Works of Shin-Kobe Electric Machinery Co., Ltd. (Hikone-shi, Shiga Prefecture) achieved a reduction in year on year power consumption of 600 kWh (a saving of 7,500 yen / month). The Tokushima Works of Hitachi Kasei Polymer Co., Ltd. (Tokushima-shi, Tokushima Prefecture) furthermore achieved large energy savings, one of its buildings achieving a reduction in power consumption for July (*) of around 50 percent compared to before the green curtain was introduced (2006).

(* Including energy consumption for other than air conditioners)

Although some sites experienced no energy conservation effect due to the long spell of very hot weather this summer, Hitachi Chemical group will continue to run the Green Curtain Project next year and beyond as one of our CSR programs.

Refer to the Green Curtain Project pages for a detailed report on the program.
