INTRODUCTION TO THE "EUROPEAN LSSH NETWORK"
"The 'European Large-Scale Solar Heating Network' is a non-profit-making
network of European institutes and companies with long experience from
development and implementation of solar heating systems for housing areas".
The network is open to all countries in order to create a common forum
for expert groups working with Central Solar Heating Plants (or CSHP),
and forms the base for continued international co-operation. Here, objectives,
results and ongoing activities, are described.
Large-scale solar heating systems or Central Solar Heating Plants (CSHP)
are here defined as solar heating systems designed to provide heat to large
and small building areas, i.e. residential buildings areas or large buildings
including more than 20-30 residential units, as well as industries, via
central block and district heating plants. There are three major types
CSHPDS - Central Solar Heating Plant with Diurnal Storage
CSHPSS - Central Solar Heating Plant with Seasonal Storage
CSHPxS - Central Solar Heating Plant without Storage (i.e. direct connection
to a heat distribution network).
The main objective of the 'European Large-Scale Solar Heating Network'
is to enhance the development of large-scale solar heating technologies
(i.e. residential heating, district heating, process heating at moderate
temperatures) through knowledge transfer on both general and more specific
issues between participating countries.
The aim is to promote a wider utilisation of renewable energy sources
by encouraging knowledge transfer (e.g. on the 'Internet') and technology
dissemination between research institutes, consultants, architects, as
well as property owners, utilities and contractors, of large-scale solar
heating. There is a need to reduce the gap between the actual status of
existing technologies and present knowledge about these technologies by
This is done by organising and/or promoting workshops and other co-operative
efforts aimed at facilitating knowledge transfer between consultants, architects,
property owners, utilities and contractors. The workshops should be organised
annually (at least) in connection to a demonstration project.
The aim is, thus, to carry on the work initiated in the CSHPSS
Working Group, IEA Solar, Heating & Cooling Programme, during 1993-1995,
as well as the work carried out within EU/APAS-project RENA CT94-0057 "Large-Scale
Solar Heating Systems" during 1995.
An established European Network for knowledge transfer and technology dissemination
of large-scale solar heating applications, which can work as a platform
for future actions.
Important experience from planning, design and implementation of large-scale
solar heating plants among involved institutes and companies, which will
improve the possibilities to make further improvements in future projects.
Improved industrial competitiveness among involved companies (i.e. consultants,
architects, property owners, utilities and contractors). Reduced investment
costs for solar collectors in general. Considerable improved cost performance
ratio compared to earlier solar heating plants. Increased market for solar
heating applications, especially large-scale applications.
The present co-operation relates to the THERMIE B project "European Large-Scale
Solar Heating Network" (Contract no DIS/1164/97, Duration 971001-990331).
A record of "European Large-scale Solar Heating Plants"
has been created. The intention is to keep this list up-to-date and complement
it with more descriptions and links to related URL-locations.
The project comprises two workshops. The first took place in Neckarsulm,
Germany, May 18-19, 1998, and the second will take place late Autumn 1998
or early Spring 1999.
The progress of THERMIE A project "Large-Scale Solar Heating Systems for
Housing Developments" (Contract no REB/00061/97, elaborated from proposal
no BU/1003/96) comprising demonstration plants in Germany, Austria, Denmark
and Sweden, will be reported.
CSHPSS Working Group
The CSHPSS Working Group was formed within IEA SHC Programme as a result
of an unsuccessful task proposal in the early 90's. The activities of the
CSHPSS Working Group have included "1994 Workshop on Large-scale Solar
Heating" in Göteborg, Sweden, August 18-20, 1994; "1995 Workshop
on CSHPSS Design", in Stuttgart, March 1995, and "1995 Workshop
on Large-scale Solar Heating" in Vienna, Austria, October 5-7, 1995,
all supported by IEA SHC Programme.
Presentations and discussions at the workshops are covered in the following

EU/APAS "Large-Scale Solar Heating Systems"
The establishment of the network is strongly linked to the study on "Large-Scale
Solar Heating Systems" (No. RENA CT94-0057) performed by eight institutes
in six countries within the APAS Program. The work is documented in an
executive summary based on three major reports, a THERMIE A proposal submitted
in March 1996 and a THERMIE B proposal submitted in April 1996:

The THERMIE A proposal comprised six different demonstration plants to
be built in six member countries: Germany, Denmark, Sweden, The Netherlands,
Austria and Italy. The proposal was later on re-submitted in 1997 comprising
demonstration plants in five member countries and resulted in the THERMIE
A project REB/0061/97. Furthermore, the "1997 Workshop on Large-scale
Solar Heating" was held in Marstal, Denmark, May 14-16, 1997.
