What do we want to achieve?


Before
The energy consumption of the computer room is equivalent to that of 26 domestic households.


After
The energy consumption and the amount of energy generated is equivalent to that of 12 domestic households.


The result
A 55% reduction in energy usage, all energy used is generated sustainably, the computer room is CO2 neutral.



How are we going to achieve our objectives?


.Savings, 53%

..Lighting, 48%

Before

162 TL 8 light bulbs
Consumption equivalent to that of 9 domestic households
48 TL 8 small light bulbs
1.4 domestic households.

After

162 TL energy-efficient light bulbs
Consumption equivalent to that of 4.6 domestic households
48 TL energy-efficient light bulbs
1 domestic household


We have compared three different kinds of lighting;
TL 5 energy-efficient, LED 1 and LED 2, placed in rooms 1, 2 and 3 respectively. We have summarised the students' opinions in this lighting survey accordingly.

Based on the results of the lighting survey as well as technical and financial factors, we have decided to adopt the TL 5 energy-efficient lighting.



..Computers, 59%

...PC Power Management, 43%

Before

The computers are sometimes left on during the night.
The computers are left on whilst not being used during the day.

After

The computers are off during the night.
Computers which are not in use are automatically switched off.




...Energy-efficient supply, 33%

Before

60% efficient supply

After

80+% efficient supply

...Printing

Thanks to the student commission 'sustainability', double sided printing has been introduced, not just in the computer room but throughout the entire UvA.


...Computer cooling


Due to the efficiency of modern computers, heat emissions have reduced considerably so that the energy used by air conditioning systems has also been reduced. This creates significant savings bearing in mind that the AC in the computer room is in use throughout the year (please note that these savings have not been taken into account in our calculations).



.Generation


..Solar panels 10 domestic households

In collaboration with De Zonnefabriek, we are placing 35kWp solar panels on a 330m2 surface, which includes buildings M, P and H. The 'Solyndra' solar panel is the first of its kind to be used in The Netherlands (see Solyndra brochure). These new solar panels will generate the equivalent to that of the energy needed to supply 10 domestic households for a period of 15 years.



..Windmills 2 domestic households

In collaboration with Amrin, we will place three modestly sized Swift windmills on the Science-park roofs (see Swift windenergy brochure). Collectively, they will generate the equivalent to that of the energy needed to supply 2 domestic households.
