Project description:
|
The feasibility study deals with the possibilities of the application of an
integrated, solar oriented concept of local solar thermal supply in a
newly built-up area. Apart from the technical application and innovative
solutions, it is important that the individual systems of thermal heat
supply are embedded in a system of central stored solar created heat. In
this context, the potential of ground storage will be examined.
In an initial step, the possibilities for application in various neighborhoods
in Münster were analysed generally. In a second step, the concept
will be implemented in one area. Furthermore, the question of
transferring these findings to other new building blocks and anchoring them
in the overall municipal planning system will be examined. At this point,
the linkages between the central local thermal supply system to other,
decentralised thermal supply systems is of particular importance.
The analysis was carried out in the new neighborhood "Coerde, Hoher
Heckenweg" which shows well qualified for a local solar thermal supply.
On basis of a meanwhile generated urban design study several versions of
solar-supported thermal supply were compared with a conventional long-distance
heating supply system.
Besides a potential CO2-reduction by 35 to 60% which could have been resulted
from an increased heat insulation and the installation of solar energy supply
systems it was asserted that only with central solar systems a surplus of
solar thermal energy beyond the actual daily demand could be generated and
stored.
Storage of thermal energy would be easier and cheaper with a multi-day storage
system compared to a long-term storage device. The additional costs in
comparison to a long-distance heating system including decentralised solar
systems would be acceptable.

Current status: |
The examination of the
area to be tested with regard to the construction of a local solar thermal
supply will be carried out in the summer of 2000 after the urban building
structures have been made concrete.
