We have prepared a lot of measuring instruments and experimental space for research. Here is the introduction for part of them.

Thermal cameras

A device which makes Far-infrared visible. It has been used very frequently because it’s easy-understanding and compact.

Here is the thermal picture of the German house of parliament in summer. It’s very famous for its designer, Norman Foster.  The temperature gradient was so clear, where the difference between the lower and the upper part is around 14 °K. Indeed, it’s very interesting to see famous architecture through the thermal camera.

Rooftop Experimental Hut

Located on the rooftop of Engineering Bldg. 1, the experimental house can change its direction freely. Now it’s mainly been used for testing of solar direct gain in winter and solar shielding in summer.

Let’s see an example. Here it’s a video made by Mr. Horiuchi (M2 in 2017).

Plenty of sunlight get into the room through the south window because of the solar elevation angle is small in winter.

PCM has been put into the internal space of floor and ceiling. It absorbs the heat of sunlight in the daytime and releases a night to improve indoor temperature.

Sunrise from the southeast, become vertical in the noon and falls down to the northwest in summer. It’s totally different for solar radiation absorption when we change the direction of the experimental house towards south and east. Please watch the movie below.

There’s nearly no sunlight in the room when the direction of a house is south.

It’s awful in the evening when the direction of a house is west.

Underground artificial environment experimental room.

It’s large artificial environment experimental room which can control its temperature and humidity. Now it’s been used for the experiment of shower heater and cogeneration machine to evaluate energy-saving standard of a residential house.
