Why Energy Saving in Schools?

• Energy Saving in Schools
• To lower the costs for education and teaching
• To give new aspects, new knowledge to the pupils
  
• Often it is easy to enthuse pupils
• Identification with the school increases
• Children take their experiences with them into
  their social environment and future

What can be done?
Most things are very simple.

• Some examples
• Avoid temperature regulation by opening the
  window
• Only use parts of the lighting, mark the light
  switch
• Shout down the lighting (in case of enough
  daylight or empty room)
• Close the curtain only when darkness is needed
  open it as fast as possible!
• Do room temperatures fit to the use of the room
  (stockroom, toilet)?
• Keep your eye on radiator valves, especially in
  rooms with different use
• Record temperature daily, weekly. Is there a
  correct plot for night, weekend?
• Some devices have stand by features. If
  possible, take them from the grid!
• Light in the room measurements of illumination,
  shut down single lamps

5
Methods to motivate!
Who pays the energy bill? In Germany mostly the
municipality but no money to save without
pupils help!

• Situation in schools
• Budgets of schools are bounded to defined tasks
• Seldom money for something special (like a school
  fête or a basketball)

• Motivation
• Share the economical profits between
• Municipality and schools
• (for example 50 for the school, 50 for the
  municipality)

Energy saving in schools in Neubrandenburg!
The Project was called Tut was!, that means Do
something! There were 19 schools with about
9.300 pupils to take part Age of the pupils was
in between 6 and 20 years One complete year of
measurement and rating! The project hits
electrical energy, heat, water and rubbish
The municipality and the schools made an
agreement The economical profits should be
shared 30 for the municipality 30 for the
schools 40 for additional maintenance and
repairing in schools

Energy saving in schools in Neubrandenburg!
First step Define the starting point The
consumption for all 4 resources for the last
three years were collected Each data point was
checked and, if necessary, changed Heat
consumption was corrected because of different
weather influences Average values were identified
and documented
After one year the new counter data were
compared with average values!

Results in Neubrandenburg
All in all the pupils lowered the energy costs
with nearly 103.400 in one year!!
All schools together got about 30.000
Because of their different success they got from
0 to 4.400
They also lowered the emissions with an amount
of 470 tons CO2e in one year!! To get savings
of emissions with that amount you have to install
nearly 850 kWPeak of photovoltaic in our area!
That means, that investments of 3,8 Million are
necessary!

Summary

• The project showed, that it is possible to reduce
  the energy cost by 10! Some of the project
  conditions lowered the effect, other municipal
  had higher results

• There was no investment in technical advices,
  only into the education of pupils for example
  investment in man power Pupils take there
  investigations with them into their life!!

• ES in that case only works because of the
  contract between schools and municipality
• ?the results depend on the motivation!
