Advantage of performance-contracting in schools
with participation of silent shareholders

• No risk of rising investment costs for the
  building owner
• No risk concerning the energy savings
• No risk of unprofitable investment
• Lower interest for the capital investment,
  compared to a conventional contracting-project
• Higher envolvement of teachers and pupils
• Higher public interest
• Reduced energy-consumption in future and
  therefore reduced risk of rising energy-prices in
  future
• Orders and work for regional companies
• Higher tax-income on local level from companies
• Less environmental damages

Saving potentials and reasons, why these
potentials are not used

• Why saving-potentials in schools in many cities
  are not used?
• There is no financial incentive for the permanent
  employees of the city municipality
• There is no incentive for the schools and the
  caretaker to change behaviour
• In many cases, the employees dont have the
  knowledge for a successful energy efficient
  building renovation
• The city may have no budget for the investment
  (even if it is profitable)
• It makes less work and there is no risk if
  nothing in the building is changed
• The citizen dont care enough about energy
  consumption and are not able to control the
  city-administration.

Staudinger School
City Freiburg/D Built between 1973 and
1978 1.200 pupils Library, youth-center,
cafeteria, 2 gymnastic halls, surface area
23.000m2 Energy and water cost before start of
the project 250.000 Euro/a Start of the project
in 1998 End 9/2007

The first performance contracting project with
citizen participation Eco-Watt Project at
Staudinger School

• Investment within the Eco-Watt Project
• Total investment 270.000 Euro
• Efficient lighting in classrooms, floors,
  gymnastic hall, toiletts
• Better control of the heating system and the
  ventilation system
• Solar thermal system to produce hot water for the
  gymnastic hall (40m2)

The first performance contracting project with

• Results part one
• Energy and cost reduction for energy- and
  water-supply of about 30
• High profitability of the efficiency measures
• Lifetime of the investment about 20 years
• Duration of the contract 8 years
• Short payback period in total (about 4 years)
• There is an additional potential for energy
  savings at the shools
• After the good experience with performance
  contracting, the municipality of Freiburg startet
  two other, bigger contracting projects with more
  than 10 schools.

Staudinger School

• Results part two
• Many activities of students and teachers
• Students competitions for correct behavior with
  energy,
• Training of energy foxes Pupils learn to
  analyse and evaluate their energy-consumption at
  home
• Energy monitor at the assembly hall of the school
  
• The care-keepers of the school are integrated

Further project development solarsave project
in cooperation with Wuppertal Institut

• New framework conditions
• Erneuerbare-Energien-Gesetz (EEG, in the year
  2000)
• Higher prices for electricity
• Tax-reduction for oil and gas, which is used in
  combined heat and power plants (0,55 Cent/kWh)
• New Project named 100.000 Watt-Solar-Initiative
• 50 Watt of electricity production per pupil
• 50 Watt of electricity savings per pupil
• 100 Watt of production or savings per student
• Big schools with 1.000 pupils ? 100.000
  Watt-Solar-Initiative or
• solarsave-projects

Measures at Aggertal-Gymnasium Engelskirchen
Before hydraulic balance About 15 pumps with
more than 6 kW have been installed Now 2 high
efficient pumps with 20,55 kW are installed
electricity-savings of about 90 of the former
electricity consumption for pumps.

• Experiences and results I

• There is a profitable energy-saving potential at
  every school
• A reduction of CO2-emissions of 50 and more is
  feasible at many schools
• Contracting and financing by silent private
  share-holders is not the solution for all
  schools. Investment through the owner usual is
  the more simple way
• Private persons in Germany are interested to
  invest in such projects
• We needed about half a year per school to collect
  the money (with low-cost advertising)
• There is interest from the side of teachers and
  the management of the schools, but usually the
  engagement for such projects has to come from
  outside of the schools
• Very positive reaction from media and press
• The projects find imitators in the public and
  private sector

• Folie 31

• Experiences and results II

• The administration of the municipalities dont
  like this kind of project so much
• They feel, that the actors interfere into the
  domain of the administration.
• The contractor gets an insight-view of the
  management of the building.
• If the project works good, there will be
  questions to the administration why dont you do
  it in the same way?
• If it works bad The administration has accepted
  the project, so it will have to bear part of the
  responsibility.
• The concept is quite new and not well known and
  usually the administration doesnt like any kind
  of risks.
• If the city owns an energy utility, the utility
  might intervene because it will lose money.
• In spite of everything Its not easy but it
  works!
