Austria, located at the Danube
river, the capital of the federal
state Upper Austria, shaped by
industry and typical central
European urban development.

6. SolarCity Objectives
Low energy construction, solar architecture.
Future –oriented approach to energy supply and disposal.
Issue of local recreation and leisure time .
Creation of a modern sociocultural, family-oriented
infrastructure .
Sustainable traffic concept.
Common, group-specific marketing campaign.
8. Urban Planning
The SolarCity designed within 1300 apartments + central
infrastructure ( local shops, sociocultural facilities, school
center, kindergarten, pastoral center, sports park).
Central tram stop ( max. walking-distance 300 m to
apartments).
Building designed of 2-4 stories high and the orientation to
the south, avoidance of shadowing.
Part of green spaces 60%, distance to the nature protection
area “Traun-Danube-Alluvial meadows” 50-80m.
9. Project organization
The following organisational measures have been taken to
deal with inter-entrepreneurial activities:
• Installation of a project supervisory board as consulting
organ during the planning phase.
• A central office coordinates the entire operational process.
• The Advisory Council is composed of top-level of politics,
administration, associations and enterprises .
• Development of a computer-assisted communications and
administration network via email and Internet.
• Documentation of the entire course of the project.
• Determination of the project objectives and contents, and
the project organisation structure in a project contract.
10. The visualization
The visualization was developed with the goal of
promoting the interactive involvement of all relevant
parties (municipal administration, architects, housing
developers, neighboring residents, future residents) in the
planning and realization process at an early stage as a
virtual realty model of the SolarCity project.
Center model …
Kindergarten model….
11. Solar Architecture
Low-energy houses , 3 passive houses.
Compact construction and upgraded
thermal isolation .
Utilization of solar energy ( active and
passive).
Ecological building components.
12. Sociocultural Planning
Quality agreements with housing
developers.
Concepts for resident participation .
City district management office .
Create a uniform marketing concept
with main focus on non-technical
aspects such as quality of life and the
environment.
13. Landscape Planning
“ Hilly park” + large recreational
facilities ( lake with swimming area,
bike path , sport area etc.)
70% increase of the lake.
Hiking trail through the nature
protection area.
Revitalization of the stream .
Construction of a sport area.
14. Power Supply
Passive : low energy houses after
principles of solar architecture.
Active : solar panels for mainly hot
water.
District heating for all buildings “
CHP with natural gas and biomass
“.
15. Construction facade panel
Wall Construction from outside to inside:
• Glass ESG(Single safety glazing) , 6-8 mm
• Air layer, 31 mm
• Solarwabe (honeycomb), 50 mm
• Panel rear, 4 mm
• Leveling insulation, 40 mm
For maximum format 1,250 x 3,050 mm
high and oblong format possible Coloration
of the solar honeycombs required Glass
with or without texture .
16. The solar facade functional principle
The honeycomb cellulose act as a solar absorber
At low position of the sun(winter) the solar load penetrates
into the solar honeycomb and heat up.
At high position of the sun(summer) the honeycomb shade
itself.
An additional mechanical sun-shading isn't needed.
The temperature difference between living space to outer
climate is balanced
17. Wall Units
Quick progress of construction
work.
Parallel production in the work.
Delivery of the envelope, incl.
windows.
No building moisture in the
exterior wall.
19. Fire protection system
After approx. 4 minutes the flames
beat from the window area on the
facade.
The fire-proofing coat foamed up as
a protective layer.
Later on the aluminum parts
started to melt.
The glazing of the panel directly
over the window shattered.
An independent spread of fire
couldn't be established after 30
minutes, the examination was
positive.
22. High-quality windows
Fixed glazed window parapet
with soundproofing system.
Fixed crossbar window parapet
with soundproofing system.
23. Disposal of wastewater for the SolarCity
Recovering nutrients of waste water instead of flushing
them away by using them in agriculture.
Fertilizer for agricultural purposes.
The black water and grey water are filtered in a
vermicomposting tank where, after the addition of
sufficient bulking material, the solids are pre-composted.
The rest is used for compost
The overflow from the vermicomposting tank is clarified in
a constructed wetland post-composting is carried out at a
compost site after one year and the mature compost can be
used in gardening and landscaping or as fertilizer for
farming.
24. The Rainwater Concept
Rainwater is dealt with as and where it occurs, in a
surface-oriented, decentralized system that makes the
natural rainwater cycle visible and comprehensible.
The drainage, collection and disposal of rainwater is
achieved mainly by means of gutters, retention hollows and
vegetated swales.
These are integrated into a coherent, interconnected
system that uses the Millstream as a receiving water body
in the southern part of the district and the alluvial
meadows as a recipient in the northern part.
The aforementioned elements of rainwater management
are an integral part of the planning of the open spaces.
26. Mobility
Path network for pedestrians and bikers.
Reduction of car traffic : nearly car-free area,
underground car-parks.
Local public transports :
- linking the tram line directly to the city center of Linz.
- bus line is extended.
Railway connection .
Bypass road Ebelsberg.
27. Traffic
Implemented these principles consistently:
• constructing all buildings in accordance with low-energy.
• providing underground parking for the 3.000 residents of
the SolarCity as well as an adequate number of parking
places for visitors.
• Motor vehicle traffic was reduced to an unobtrusive
minimum by routing it only along the promenade and to
the individual underground parking lots in order to
protect the dwelling environment and the children.
• Within the settlement, maximum priority shall be given to
pedestrian and cycle traffic.
28. Conclusion
Linz; Good Sustainable Practice as specified by the United
Nations and the international community at large as
successful initiatives which:
• Have a demonstrable effect and tangible impact on
improving people’s quality of life;
• Are the result of effective partnership between the public,
private, and civic sectors of society;
• Are socially, culturally, economically and environmentally
sustainable.
