| - | ====== Problem ====== | ||
| - | * LUT has multiple computer rooms available in 24/7 use. These classrooms | + | ====== Idea and motivation ====== |
| - | * This issue could be solved | + | |
| + | Modern classrooms | ||
| + | |||
| + | We will try to solve this problem with our automated system | ||
| + | |||
| + | The main motivations for this project are the energy savings, but the increased comfort from the automation of some things, such as lighting or heating, is a good benefit as well. | ||
| ====== Vision ====== | ====== Vision ====== | ||
| - | * A classroom with no power usage when not in use | + | Our vision is a classroom with no power usage when it is not in use. In addition to the implemented features, we also thought about how this system could be improved in the future. We focused on the possibilities in 5-10 years, although some these things might be partly possible to implement even today or in the near future. |
| - | | + | ==== Smart windows ==== |
| - | * Power usage should fall down to zero when the last person leaves | + | Automatic dimming of windows could be useful to control the amount of sunlight in the classroom. This could work together with the lighting, since the brightness of the lights can be lowered when there is a lot of natural light available from outside. |
| + | ==== Smart walls ==== | ||
| + | Smart walls can detect people inside the room more accurately than simple motion sensors. The walls could also be used as an interactive surface when necessary. The interactions could possibly be based on either touch or gestures. There would also be no need wall switches since the interactions could be done on the interactive wall. | ||
| + | ==== Smart heating ==== | ||
| + | Heating could be automated based on the classroom schedule. This way the classroom could be already automatically heated in the morning when the first lecture starts and the heating can be turned | ||

| - | * We can take standby power calculations researched by Lawrence Berkeley National Laboratory and use them in our calculations. According to their research an LCD display consumes 1.38W of power in sleep mode and a desktop computer consumes 21.13W on average in sleep mode. | + | * We can take standby power calculations researched by Lawrence Berkeley National Laboratory and use them in our calculations.

| * In these estimations the hardest part is estimating what portion of the year are the computer classes not in use. We can roughly say it is at least half of the day since the rooms are not used at most nights and daytime use is small on holidays and summer. | * In these estimations the hardest part is estimating what portion of the year are the computer classes not in use.
