City office where measures for controlling global warming were done with morning-glory

Not only measures for controlling global warming but also to improve the cityscape as "Curtain of the morning-glory", the one of this experiment. The morning-glory was used in five places such as the city office this public office building west side walls (the second floor-the 14th floor). In the area of greening on the wall, about 1300 square meters, and the number of total stocks of morning-glories used is about 3500 stocks.

The following effects were able to be confirmed in this public office building.

*The indoor temperature decrease
When the indoor temperature was measured on holiday (air-conditioning non-operation day) of August, the temperature decrease of 1.4-2.7 degrees is confirmed.

*Effect of reduction on air-conditioning driving day
The city gas reduces 156 cubic meters a day (3.8% of the amount of the air-conditioning driving gas use) to electricity by the comparison with the previous year by 321 kilowatt-hour day (3.6% of the amount of the air-conditioning driving electricity use). These correspond to the carbon-dioxide emissions 31 tons in the calculation on the air-conditioning driving day (the 60th).
- About 663,000 yen and it estimates to the cost reduction with air-conditioning.

*About 80 percent of the staff feels "Actually, externals" it became cool a little.

City office this public office building and image of Sarmocamera. It is understood that the temperature in the part where the morning-glory has grown has fallen.

Being possible to smell on the day is caused by the leaf of the morning-glory and the cause where a direct effect of air-conditioning is caused is the one. Moreover, the transpiring action because of the surface of the leaf can be expected. The effect on psychology by an attribute of the morning-glory of transmitting on the wall and expanding and visual beauty cannot be missed.

The labor cost for the water fee and the maintenance at the seed fee of the morning-glory and the promotion is not provisionally calculated in the report though it is when electricity and the gas bill were able to be saved for about 663,000 yen. Ton ton or a few points of surplus money perhaps. mightHowever, energy was able to be saved in above all, and being possible to cooperate in the carbon-dioxide emissions reduction have the meanings.

There is a story of using the living body construction materials for all buildings to improve air pollution in a certain SF system cartoon. The effect of looking like like this might be achieved though it seems to take time to put the living body construction materials to practical use still even by a current technology.
