Working in a “smart” building

For more than a year I have the pleasure to work in an office in the John Britten building at the University of Canterbury. The office is light, friendly and spacious. I should be more than happy but this building comes with a twist. It is smart. The room has a motion sensor and a temperature sensor. The lights are suppose to go on when activity is detected and the window is suppose to open when it becomes too hot in the room. Notice that this smart building does not have the ability to regulate the heaters. If I switch the heater fully on and thereby create a little sauna then the building will open the window instead of regulating down the heater. I am not sure if this is smart.

The biggest problem is that the window’s behaviour could best be described as neurotic. It opens and closes nervously without considering the noise it makes or the noise that the construction site outside is creating. The only way to tame this autonomous monster is to log into a website and set the window to manual. There is no switch or lever that I could use.

LEGO EV3 Robot Measures the Environment

So I ended up creating a little LEGO robot that would log the environment of the office and the opening of the window in the hope to detect a pattern. Something to convince me that there is method in this madness. Other than that the windows close at 5pm sharp I could not. But along the way I learned a bit more about information visualization on the web and how to to create a useful little logging robot. Have a look at the graph that I produced.
