| + | Most people don’t think about turning school computers off and nobody unplugs their classroom electronics after leaving. Our solution provides convenience and ease of mind since those who do use school electronics responsibly won’t need to worry about shutting down devices either. Everything happens unnoticed automatically. That small convenience is the social sustainability our concept brings. | ||
| + | Most of our projects sustainability is on environmental side. The whole idea of this concept is to save the last bit of completely wasteful power usage in classrooms. Although the impact of one room is small the combined impact of hundreds of classrooms saves a lot of energy thus reducing the emissions caused by electricity usage. | ||

| - | We can see from the calculations that the amount of money saved is quite small in the scale of a university but when we include all the classrooms into consideration the energy savings and cost benefits can become significant. The real issue is the cost of implementation which in our example using switches would require multiple switches in each classroom and wouldn’t be worth the investment. Our solution could be developed further and if we could manage a complete classroom with one switch the investment could be worth it. It is of course also a way of branding and enhancing the university’s image. Green campus image sells, and this solution would bring another dimension to that. | ||
