Energy and water saving

In the past five years, Leiden University consumed on average approximately 580,000 Gigajoules of energy per year. Since 2010, we have witnessed a decrease in energy consumption of a few percent a year. In addition, since 2010, Leiden University has been purchasing green energy, which has reduced its average CO2 emissions by 75%.

Future energy consumption

The energy costs are expected to continue to grow in the coming years. In addition, energy consumption is currently responsible for greatest negative impact of the university on the environment. It is therefore important to continue to reduce our energy consumption as much as possible. This will be one of the spearheads in our new environmental policy.

Energy teams

Within the university, energy coordinators have been appointed both on the central and on the faculty level to monitor and implement measures to reduce energy consumption. In addition, in buildings housing more than fifty employees local energy teams have been appointed who are responsible for analysing the annual water and energy consumption figures, devising measures to save electricity and water, and evaluating the implemented measures. These energy teams consist of the energy coordinators, as well as representatives of the faculty administration, technicians from the Real Estate Expertise Centre and the central environmental adviser.

The annual budget of the Real Estate Expertise Centre includes resources to implement energy-saving measures.

What can you do?

As an employee or student you can also contribute to saving energy and water. A few tips:

  •  Turn off the lights when you leave your room, even if it is only for fifteen minutes.

  • Turn down the thermostat in your office.

  •  Select a good spot for your desk or work table (to ensure your workplace is properly lit).

  • Put an energy-saving bulb in your desk lamp.

  • Put your computer in stand-by mode if you leave your workplace, and put it in sleep mode or turn it off if you do not plan to use it for the next half-hour or more.

  •  Do not use a screensaver: turn off your screen if you are not using it.

  •  Disconnect your power supply from the power outlet if you are not using it.

  •  Use central facilities (for instance a multifunctional for printing, copying and scanning, coffee corners, and fridge and freezer facilities). These are less harmful to the environment.

  • Make sure that devices are properly filled when you turn them on (dishwasher, autoclaves).

  •  Cycle to and from work; it’s also better for your health.

  •  Immediately report leaky faucets and toilets and defective lights to the service desk of your building.

  •  Use the low volume flush mode of the toilet.
