I run on muscle power

Revolving door

The only energy this revolving door uses is human muscle power. A revolving door is also more effective at keeping heat inside a building than a sliding door.

I am waiting for you

Borrow a bike at reception desk

Do you need to go to another building? Use a loan bike! A good alternative to the car or public transport. You can loan a bike from this reception area.

I am easy

Floor covering

The floor covering in the buildings is easy to keep clean, which means it lasts longer and we do not need to replace it as frequently.

I switch off by myself

Lighting

Many offices and meeting rooms have sensors: the lights switch off after a period of no movement in the spaces.

 

​I burn with desire until there is light!

Lighting

Striplights on the window sides of the teaching areas, offices and meeting rooms react to daylight. As the amount of daylight increases, the lights automatically dim.

I keep you fit

Stairs

If you take the lift, the lift consumes energy and you do not. If you take the stairs, you are the one consuming energy. Walking up stairs is more physically intensive than, for example, jogging: you burn the same number of calories in half the time. Two minutes of walking up stairs already has a positive effect on the body's ability to burn calories (upwards of 280 kcal every 30 minutes), and repeating this multiple times a day has a major impact on your blood sugar and cholesterol.

This is my retirement

Kiosk computer

Computers from teaching areas that still work but are too old to be used for teaching purposes are given a new lease of life as kiosk computers in the buildings.

 

I have content

Windows

The windows are double glazed. Double glazing is double glass window panes separated by a space, or cavity, containing dry air. Since air has high heat resistance, the space reduces heat transfer. The result is cooler interiors in the summer and warmer interiors in the winter. We do not use air conditioning in this building.

 

I sense your presence!

WiFi routers

The WiFi routers in the buildings measure the activity of any devices present. In the absence of devices, the router automatically switches off after a while, saving energy.

Black and white and double vision

Printer-copiers

The multifunctionals (printer-copiers) are set by default to print double-sided and in black and white. Print jobs are only executed if you enter the command at the printer itself.

 

Honesty lasts forever!

Vending machine

All our vending machines dispense Fairtrade coffee and tea.

 

I am a subject of debate!

Cups (plastic, paper, porcelain)

Opinions about the sustainability of various types of coffee cups differ enormously. The pros and cons at a glance:

  • Paper is difficult to recycle because it has a thin layer of plastic.
  • Plastic cups can be recycled if they are collected separately.
  • Chinaware lasts longer but needs to be cleaned frequently, which consumes water and energy.

 

I have an eco programme

Dishwasher

You can save water and energy by using the eco programme, which consumes a couple of litres of water and 0.28 kWh less compared to the main programme.

 

I am an in-between

Waste

Waste is sometimes unavoidable. Fortunately, more and more Utrecht University locations have waste bins where waste can be separated on the spot. You can already separate and dispose of your plastic waste there. The same will soon be true for paper, organic and other waste, which will result in a significant reduction of residual waste. Discarded plastic will be recycled into other products.

 

I sleep at night

Computers in the study areas​

All computers in the study areas and computer rooms are switched off every evening at 10:15 p.m. They are switched on again at 7:15 a.m. on working days.

 

I also do not work during the holidays!

Computers in the study areas​

During holiday periods, the computers in the study areas and computer rooms do not automatically boot up. It is up to the user to turn the computer on.
