    What is performance contracting and how does it works?
    • Folie
    What is performance contracting and how does it works?
    • Folie
    • 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
    Advantage of performance-contracting in schools with participation of silent shareholders
    • Folie
    Saving potentials and reasons, why these potentials are not used
    • Folie
    • 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 don´t 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 don´t care enough about energy consumption and are not able to control the city-administration.
    Saving potentials and reasons, why these potentials are not used
    • Folie
    The first performance contracting project with citizen participation: Eco-Watt Project at 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
    • Folie
    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)
      • Photovoltaik system to produce electricity from sun light (2 kW)
      • Measures to save water: water saving shower head, flushing of toiletts
      • Money comes from 90 people: teachers, parents of students, private persons (the limited partners , Kommanditisten)

    • Folie
    The first performance contracting project with citizen participation: Eco-Watt Project at Staudinger School
      • 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.
    • Folie
    The first performance contracting project with citizen participation: Eco-Watt Project at 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
    • Folie
    The first performance contracting project with citizen participation: Eco-Watt Project at Staudinger School
      • Results part two:
    • Energy monitor at the assembly hall of the school:
    • make efficiency visible!
    • Folie
    The first performance contracting project with citizen participation: Eco-Watt Project at Staudinger School
  • Further project development: solar&save 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
      • solar&save-projects
      • CEO of the solar&save contract Ltd is Dr. Kurt Berlo, Wuppertal Institut für Klima, Umwelt, Energie GmbH

      • Aims of the project:
      • Making efficiency more attractive in combination with PV
      • To show, that energy-efficiency and PV are profitable investments

  • Measures at Aggertal-Gymnasium Engelskirchen
    • Folie
    Before hydraulic balance: About 15 pumps with more than 6 kW have been installed Now: 2 high efficient pumps with 2*0,55 kW are installed electricity-savings of about 90% of the former electricity consumption for pumps.
  • The solar&save projects: investment into climate protection

    • Folie
    Articles in newspapers and journals: 3 examples SOLARboulevard Frankfurter Rundschau taz, Berlin
    • Experiences and results I
    • Folie
      • 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
    • Experiences and results II
    • Folie
      • The administration of the municipalities don´t 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 don´t 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 doesn´t 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: It´s not easy – but it works!
