Square JS is a complex owned by Nippon Sosei Life. At Square JS, we use a thermographic camera to capture and record the differences in thermal insulation properties of living rooms that vary depending on materials and construction methods, and we conduct the "Thermo Experiment displays" to apply it to future living spaces. This facility attracts many customers, such as apartment complex management companies, housing supply corporations, and local government officials, based on the keyword "housing complex." However, due to the technical nature of displays's content, it was difficult to gain a full understanding of the facility. Therefore, through this video, we show that the thermal environment of living rooms has improved due to changes in times, construction methods, and materials, and then tour the actual space so that the complex contents of displays can be understood smoothly. < Video Story >Showa 40's. An inquisitive elementary school student, Manabu learned about the thermal insulation of living rooms from his father Kiyoshi, the architect of the housing complex, and became interested in future research and improved spaces. Then, the space is twisted, and you are transported back to 202 X! Kiyo is very excited about the future space. In learning, the temperature of the living room changes depending on the material and construction method. When he returned to the Showa period, his mother Keiko prepared meals and waited for them to return. They enjoyed the family reunion, imagining the future that would come to Gaku one day.
