April 24, 25, and 26 was the third International Ecovillage Conference in Tokyo http://begoodcafe.com/main/ecvc2009
On May 3 I returned to Fujisawa from Hokkaido, and the next day, May 4, I departed for Mie Prefecture. Hideto Oshima, a straw bale architect and builder, is building a straw bale home in Mie Prefecture for a client. I installed 12 temperature and relative humidity sensors, 9 within the north straw bale wall, one within the foundation, one sensor monitors the room, and one sensor monitors the outside environment. The primary purpose of the experiment is to compare two slightly different foundation systems. Both Oshima and Oiwa-sensei use a “U” shaped foundation with an air passage under the straw bale wall vented to the outside. Oshima separates the air passage from the straw bale wall with a layer of earthen plaster while in Oiwa-sensei’s design the first course of straw bales are in direct contact with the air passage below.
Finally back in Fujisawa. In addition to research, managing the student permaculture garden. Spring crops look real good! Research studio raises ukokke, a breed of chicken renown in Japan for its small, expensive eggs traditionally used in Chinese medicine. With chickens, who needs a tv?
Similar to the Toilet Hut, the interior is finished with an earthen plaster while the exterior is finished with lime plaster. In order to access the straw to monitor the moisture content of the straw using a GE Bale Master Moisture Meter, I set three PVC screw top lids into the wall.
