SolarRegion Freiburg2

A r r a n g i n g t h

The "Freiburg mix" of local

factors: of municipal policy

and citizens' commitment, of

nature and climate, of exper-

tise and innovation has

created a fabric of a unique

quality. Solar projects from

many sectors give evidence

of the creative power of the

City of Freiburg and its region.

They are convincing demon-

strations of the sustainable

change of industrial society.

I cordially invite you to visit

SolarRegion Freiburg and

our projects. Let the Freiburg

approach of an environmen-

tally oriented energy policy

stimulate yourself to new

initiatives. The future is in the

making.

Dr. Dieter Salomon

Lord Mayor of the City of

Freiburg

SolarRegion Freiburg is the

blueprint for sustainable

regional development. Cessa-

tion of nuclear energy, cau-

tious use of valuable energy

sources and climate protec-

tion are the objectives of the

energy policy of the City of

Freiburg. The implementation

of solar power in everyday

practice in Freiburg has set

examples and sparked ideas

of worldwide attention.

An unequalled number of

companies, skilled trades

businesses, organisations

and associations, research

institutes, experts and re-

sponsive citizens have com-

mitted themselves to the

development of solar energy.

With strong support from the

City of Freiburg, new applica-

tions of solar energy are con-

tinuously being explored,

contributing the sustainable

development of the region.

Freiburg boasts a distinctive

feature as the leading a centre

of expertise in solar energy.

This has won Freiburg the

German Solar Prize and a

top position in the "Solar

Bundesliga" contest.

The success of our municipal

solar policy is based on two

factors: cooperative partners

from different sectors and a

broad discourse in society

backing the objectives of our

energy policy. Only concerted

action of politics, economics,

research, NGOs and the indi-

vidual citizens brings the

necessary swing for big steps.

The City of Freiburg supports

the growth of solar energy in

terms of quantitative expan-

sion as well as in its qualita-

tive contribution to sustain-

ability. Forum SolarRegion

Freiburg develops and coordi-

nates projects in the areas of

education and training, econ-

omy, and tourism. As a pool

of information, the forum is

both an interface of the net-

work and a contact for en-

quiries.

In 1986, the year of Cherno-

byl, the Municipal Council of

the City of Freiburg adopted

a concept of energy supply

combining three strategies:

● energy saving (in particular, thermo

insulation of buildings)

● renewable energies(solar energy as pilot

technology)

● efficient technologies(of power generation,

i.e. co-generation of heat

and power)

ness fields have been growing

around solar power.

Solar economy has received

a further boost by Solar Info

Centre, a technology park

dedicated to solar building

and energy efficiency, with

consulting businesses, edu-

cation centre, demonstration

and test areas.

Outside the solar industry as

well, innovative enterprises

The large increase of enter-

prises in the solar industry in

the region proves that it is not

only possible to live with the

sun, but also from the sun.

Solar energy secures jobs

and economic prosperity on

one side, environmental and

climatic protection on the

other. Thus, it fulfils the prin-

ciple of sustainability.

Solar-Fabrik AG (Solar Factory

plc), founded in Freiburg as

a small and medium-sized en-

terprise, has become the most

successful producer of photo-

voltaic panels on the German

market. The award-winning

building with its 'Zero Emis-

sions' concept is representa-

tive of an entire solar econo-

An unspoilt environment is a

most valuable asset for the

tourist business in the Black

Forest, the Kaiserstuhl hills

and the Upper Rhine region

and it is part of the quality of

life. Therefore it is only logical

to discover solar energy for

tourism. Freiburg attracts

'solar tourists' from all over

the world. Specialists and inter-

ested visitors discover perspec-

tives for the solar future by

real examples.

In SolarRegion Freiburg, this

path has been explored by

the 4 star hotels Victoria and

Hirschen with their ambitious

energy concepts, or the rural

pub Rappenecker Hof on

Schauinsland, with off-grid

power supply developed by

Fraunhofer ISE and subsidised

by badenova innovation funds.

The Dreisam river bank café

and the bistro in Solar-Fabrik

welcome their visitors. Solar

absorbers keep a comfortable

temperature in the Strandbad

swimming pool.

The two solar towers of the

central station mark the entry

to the solar city Freiburg.

For their solar fronts special

modules were de-

veloped in Freiburg.

Nearby, the "Mobilé"

bicycle station inte-

grates environ-

ment-friendly

energy and

mobility.

Over and above economic

interests and municipal policy-

making, it is the voluntary com-

mitment of the citizens which

is the motor of solar energy de-

velopment.

The commitment of our citizens

provided the funding for the

"Regio solar power plant".

This consists of a network of

large photovoltaic installations

in different locations. The solar

plant on the grandstand roof

of the SC Freiburg soccer stadi-

um has attracted particular

attention. Today it holds four

PV units with different funding

schemes, each involving citi-

zens as shareholders.

Many homeowners invest into

own solar electricity plants. They

are supported by the regional

power company badenova.

Their subsidy scheme is in

turn based on the commitment

of their customers and their

financial contribution. Solar

thermal collectors as well have

developed from the ecologically

valuable to the economically

reasonable.

Parish communities, sports

associations and schools in

Freiburg show a particular

commitment to solar energy,

initiating a large number of

projects.

Freiburg is the home of Fraun-

hofer Institute for Solar Energy

Systems ISE, the largest Euro-

pean solar energy research

institute. Fraunhofer ISE de-

velops systems, components,

materials, and processes for

the business areas: buildings

and building services technolo-

gy, solar cells, off-grid power

supplies, grid-connected re-

newable power generation

and hydrogen technology.

Practical feasibility and eco-

nomic viability are the guide-

lines for innovative solutions

'made in Freiburg'.

Air conditioning systems de-

veloped by ISE for a university

hospital laboratory and for the

Chamber of Commerce and In-

dustry operate almost entirely

on thermal solar power. The

building of Fraunhofer ISE is in

itself a fine example of energy-

efficient architecture. In the

neighbourhood Fraunhofer

SOBIC is an information center

on solar building innovation,

and PV-TEC provides test and

development facilities for the

solar industry.

Expertise and know-how of

Fraunhofer ISE radiate into

many projects and enterprises

and constitute a major asset

for SolarRegion Freiburg as a

business location.

on

Solar constructions for the

future imply much more than

solar panels on the roof. Both

passive and active use of solar

energy combine in integrated

concepts which are architectur-

ally appealing and maintain a

high quality of life.

In Freiburg these include ex-

perimental projects like the

self-sufficient solar house by

Fraunhofer Institute 1992 or

the rotating structure of Rolf

Disch’s solar house Heliotrop.

There is innovation in new

buildings as well as in the re-

furbishment of old buildings

such as the Familienheim

apartments Wilmersdorfer

Straße.

Solar residential estates imply

environmental advances in

many respects: energy, traffic,

water, and nature preservation

are all integrated in planning.

The Plusenergiehäuser® ("ener-

gy-surplus-houses") of the

Schlierberg solar estate gener-

ate more energy than the

residents consume. The new

districts Vauban and Rieselfeld

were consequently build ac-

cording to an advanced stand-

ard of low energy consumption.

For the success of solar energy

in the region appropriate train-

ing in the skilled trades is im-

perative. Installation businesses

are pivotal as an interface be-

tween technological innovation

and the users and customers.

Expert planning, installation

and maintenance demand ap-

propriate technical skills of the

workmen and an open-minded-

ness for renewable energies.

Freiburg is renowned for its net-

work of training institutions cov-

ering energy-saving construc-

tion, efficient energy supply and

renewables: Richard Fehrenbach

vocational college and its state-

of-the-art equipment for appren-

tices, the academy of the trades

corporation for continuing train-

ing, Offenburg University for en-

gineers, Freiburg solar university

for scientists, EnEd international

education center for energy so-

lutions, and more. Backed up by

research, international

associations (ISES, ICLEI) and

companies, Freiburg develops

customised training programs

for partners all over the world.

Solar power has long made its

entry into education in Freiburg.

There are major school projects

outside the technical training.

One third of the schools in Frei-

burg run their own solar pro-

jects, initiated by committed

teachers, pupils and parents.

Hands-on educational programs

fascinate school children and

young people.

Education and training

Marketing and fundingThe regional power supply

company Badenova runs a

subsidy program supporting

customers who want to install

photovoltaic panels. The

scheme is financed from elec-

tricity sold under the brand

label regiostrom. The small

surcharge on regiostrom (as

compared to the standard ta-

riff) is invested exclusively

into further regiostrom power

stations: photovoltaics, bio-

mass and small hydropower.

This has has improved the

economic competitiveness

of solar energy and brought

a continuous increase of

environmental friendly elec-

tricity generation. 10% of

the Badenova customers have

voluntarily opted for electricity

from regional and renewable

energy sources. Badenova also

offers subsidies for thermal

collectors.

In 2001 Badenova initiated the

'Innovation Funds for Climate

and Water Protection' to sup-

port projects which combine

maximum environmental ben-

efit, a high multiplier effect

and economic advantage in

practical application.

Other approaches to financing

were also for the first time de-

veloped in Freiburg and have

since then been successfully

implemented and replicated:

co-op models of participation

as well as concepts on a funds

or on a shareholder basis.
