How we saved water with students

What have students done• When you wash your hands,

you have to put the soap first and after that you will open the water tap.

• When you take the shower after sport lesson, you have to only wash yourself, not to stand in the shower.

• Drinking water in jugs.

What was the influence• In one time it does not

matter, but at school you wash the hands many, many times during the year, so it will make an influence.

• It will save almost 400 liters after each sport lesson.

• Pupils will not wait with running water until it is cold enough.

What can we do in the kitchen

Tasks• Don’t wash dishes under

running water before you put them in dishwasher.

Estimated effect• It will save around 200 liters

every day, which will be 4 000 liters every month.

• It will also save heat because you use warm water.

What have students done to save electricity

• Students have made instructions or notes so you remember to switch off the lights.

• Remind younger students to save electricity.• Take care of that there are no unnecessary

lights or computers on if you don’t need them in the school.

What can teachers do ?

• Everyone takes care of her or his own classroom that there are no unnecessary lights on.

• Turn off the computers if you don’t use them.• Turn off the lights from corridors during

lessons.

What has our service man done

• Decrease the air condition on weekends and on night time and if the temperature outside is under -10 C degrees, put the air condition only on ¼ effect.

• Take care that outside lights are not on at night time.

How we save heat

• We dropped the heat so much that temperature is 20c degrees. When we started it was in some classrooms almost 25 degrees.

• We checked with a thermographic camera the doors and windows and after that we sealed the worst (leaky) places.

Summary

• With those measures we achieved following savings:– Electricity: 1,9 % savings in the first year and 17,6 % in

the second year.– Water: the first year was better and we got 36,2 %

savings. In the second year we got “only” 24,1 %.– Heat: the first year was much better than the second

one. We saved 10,1 % in 2010 but in 2011 we didn’t save at all (we wasted 2,3 %).

– Waste: we got both years the same 14 % savings.– In Finland this meant 2 000 € to our school.
