Over the past few years there has been a lot of talk in Japan to make roofs green in order to reduce the heat-island effect. Cities like Tokyo, Osaka, and Nagoya in particular have become a lot hotter in summer as the concrete used in buildings absorbs heat and then releases it at night. It is amazing how there is so little difference between daytime and nighttime temperatures in August.
However, the movement to green the tops of buildings seems to be gaining strength under "eco thinking" as it is seen as a way to reduce the amount of energy used on air conditioning. Many companies handling western red cedar see this a great business chance so I was very happy yesterday when I noticed that a house in my neighbourhood had just had its roof greened with the use of WRC.
Not only will this rooftop green space have a positive environmental impact, but it also gives this urban family a yard to relax in. Usually the footprints of homes in Tokyo take-up the entire property so homeowners do not have the luxury of yards or gardens. Now I just have to figure out how to get invited over for a BBQ!
