Locations of the various energy generation systems:
Compression heat pump (groundwater), condensing
gas boiler, thermal collectors, groundwater conveyor and
injection wells and photovoltaic elements

The addition of storeys to all buildings
using wood as the construction material
not only creates space for new, contemporary
floor plans, but also contributes
to the building’s thermal insulation. An
innovative composite thermal insulation
system comprising resol foam and
vacuum insulation is integrated into the
façades themselves.
The central heating plant exploits
geothermal heat from the groundwater
close to the surface. Then there are the
thermal collectors on the roofs and the
gas condensing boiler which comes into
play at peak periods.
Photovoltaic elements ideally feed as
much energy into the public grid as is
fed from the outside to run the system,
in the form of gas for the gas-operated
compression heat pump or electricity
for the plant pumps. The more these
quantities balance each other out, the
more even the CO 2 balance is.
For GWG München, the Lilienstrasse
North model project represents a way
of finding “new ways of investigating
existing buildings” and taking “a step
towards the renovation market of the
future” together with the Fraunhofer
Institute and Ebert Engineers. Architect
Wolfgang Stocker sees this measure
as the key to a sustainable future for
construction. This project goes far
beyond using new types of full thermal
insulation and other innovative materials,
by showing how a future may look
that does not think in terms of individual
building activities but in complex
systems.
