Sun hitting the school building

Hello, I am Inoue from the Department of Global Information and Management. Together with Yamazaki sensei and Kodaka sensei, I teach the Engineering Context 1A class at Hakusanroku campus. The first semester classes are reaching their final stages and students are working hard on their final presentation.

How is everyone doing during this nationwide heatwave? On July 23, 41.1 degrees Celsius was recorded in Kumagaya city, Saitama prefecture. Apparently, this is a national new record since five years ago. Although Hakusanroku campus is one to two degrees cooler than downtown Kanazawa, we are still experiencing high temperature around 34 degrees with strong sunshine. There is little shade to prevent the sun streaming into the school building (see picture 1). You many wonder what it is like indoors. Actually, it is quite cool and quiet. In this journal, I would like to introduce the school's air conditioning system.

First off, ICT's main building has two floors. As you may have seen in other pictures, both floors are connected under a high ceiling. It may be difficult to distinguish the two floors (see picture 2). The ceiling is so high that you could probably build a third floor (see pictures 3 and 4). In addition, the walls facing the courtyard are full framed grass windows. The whole building is feels open and quite spacious. You may wonder how we keep such a building cool.

At first glance, many fail to even find the air conditioning units. Looking up at the ceiling or wall or listening for the sound of the air conditioners will do you no good. Actually, Hakusanroku campus's air conditioning system is under the floor. There are vent holes in the floor in and out of the classrooms (see picture 5 and 6). You can feel the gentle cool air coming out of the vent holes if you put your hand near them. The air stream is not strong and does not blow up dust. The space humans can detect is only two meters from the ground. Therefore it may actually be more efficient to have air conditioning in the floor. In addition, there are multiple vent holes, which means that less airflow is necessary to circulate the cool air. This leads to the quiet sound. Removing the air conditioner from sight also increases the interior aesthetics. I doubt many schools in Japan have an air conditioning system like this.

In the classroom, students can enjoy the scenery of beautiful sky, mountains, and green grass out the windows unaffected by the heat as they study, (see picture 7). This is another streng of the Hakusanroku campus. The mountains will change red in autumn and white in winter. What will it be like then? That is a topic for next time.
