Health Case Study: Japanese Green Curtains
Kyocera, a Japanese manufacturer, covers the outer façades of its buildings with Green Curtains to lower indoor temperatures, save energy, and reduce pollution.
Living curtains of decorative or edible climbing plants help to cool the air through water evaporation, reducing the use of air conditioning while at the same time providing natural shade and sequestering carbon emissions.
As of 2016, Kyocera’s Green Curtains covered an area of more than 31,000 ft2, resulting in significant summer energy savings, positive aesthetic effects, and food for their cafeterias. The project has spread to 27 factory locations in Japan.
