FAQ energy conservation

Why have not all toilets at TU/e been equipped with motion sensors?
In new buildings like Atlas, Flux, and MetaForum the lighting in toilets is operated by a motion sensor. Eventually TU/e wants to apply this system throughout the campus, but a system in a building will not be replaced until it has reached the end of its natural life cycle. In this way we prevent the discarding of materials that are still good. 

What can I do myself to save energy?
At the end of your working day you should switch off your PC/laptop including your monitor, loudspeakers, printers (also in the corridor), battery chargers of your telephone, lights, kitchen equipment (microwaves, coffee machines, water boilers), fume cupboards and research equipment. 

And when I leave my working space for a moment?
Turn off the light and switch your computer to the stand-by mode. The latter can be set automatically in Windows via Power Options. 

In the stand-by mode a PC consumes 8 Watt per hour. Normally a PC with a 19-inch LCD screen uses 100 Watt per hour. If a computer is actually used 6 hours per day, it can be in the stand-by mode for 2 hours. This results in a saving of 0.184 kWh per day. Given 225 working days that is 41.4 kWh per year, which implies that the 3,000 permanent workstations at TU/e together can save 124,200 kWh; which is equivalent with the power consumption of 35 households! 

Which buildings on the TU/e campus consume the most energy?
Lab buildings such as Spectrum, Cyclotron and Helix are real energy guzzlers, due to the huge amount of air that is continuously refreshed, cooled and conditioned. In older buildings the power consumption is often not so bad. They need less cooling, and cooling requires more energy than heating.
