The 23rd UTokyo Techno-Science Café ReportDecember 11, 2016 工学系11号館講堂


The 23rd Techno-Science Café was held on December 11, 2016. About 20 students mainly from elementary school participated in this event. The program consisted of two parts. In the former half of the event, Assoc. prof. Mae from the department of architecture gave a lecture on the energy consumption in homes such as gas and electricity, including a workshop and a simple experiment.
In the latter half, the participants learned the ways renovating their house to improve the housing performance by playing sugoroku.


In the workshop in the lecture, the students examined their residential energy consumption including heating, cooling, water heating, and lighting, by making a pie chart according to the monthly notices of gas and electricity they brought respectively. Mr. Mae asked them and their parents which factor they think account for the most before starting the workshop, and compared the prediction with the real conditions revealed in the workshop, so that they can really understand what they consume energy for at home.


In addition, Mr. Mae showed the difference in the surface temperature distribution of five windows with different performance and property, in which were dry ice put in advance, by using a thermo camera, because windows are the greatest weakness when it comes to thermal insulation of buildings. The window frames are made of either aluminum or plastic. The students checked the surface temperature difference by actually toughing the windows, too.


Moreover, Mr. Mae carried out a simple experiment to show the difference in conductivity of aluminum and plastic. He showed that you can easily stick an aluminum spoon, which has high conductivity, into an ice cream frozen very hard, while you cannot with a plastic spoon, which has low conductivity.


In the latter half, the students learned the ways of improving the housing performance, by playing sugoroku and reading aloud the sentences written in each cell, whose contents are related to the problems in homes, the resolutions to them, and examples of effects of renovations. The students looked very excited while playing sugoroku.


At the end of this event, the students completed the questionnaire. I hope this event provided a good opportunity not only for the students, but also for their parents to pay attention to and revise the energy tconsumption in their homes.
