  • 1. LOGO THE SOLAR CITY LINZ, AUSTRIA
  • 2. LOGO Prepared by: 1- YOUSEF HASANIN P62306 2- MUSTAFA TALIB P60915 3-SAHAR ABD ALI P65295 presented to : PROF.IR.DR. RIZAATIQ RAHMAT
  • 3. LocationLinz is one of the biggest cities in Austria, located at the Danube river, the capital of the federal state Upper Austria, shaped by industry and typical central European urban development.
  • 4. ScopeSolarCity Linz-Pichling; Austria , 1992 SolarCity Linz-Pichling; Austria , 2006
  • 5. Scope Client: Municipality of Linz Financing: Municipality of Linz, European Community Project: has been constructed in 2005 Master plan: Roland Rainer Architects: READ (Renewable Energy in Architecture and Design):Thomas Herzog + Partners Environmental engineer: Norbert Kaiser Landscape architect: Latz + Partner Consultant: Renzo Piano Building Workshop Local coordination: Heinz Stogmuller Total Cost 190.000.000 € with Residential buildings 125.000.000 € and Infrastructure 65.000.000 €
  • 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.
  • 7. Project stages time 1992 Master plan Prof. Rainer 1994 Local-Sustainable-Development-Planning (Lassy) 1996 Urbanistic Ideas completion (Treberspurg) 1997 Landscaping ideas completion (Dreiseitl) 1998 Architectural completion 2005 Completion
  • 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 isnt 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.
  • 18. Sound proofing Wooden Framework 16 cm. Brick Wall 38 cm, double-sided plaster.
  • 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 couldnt be established after 30 minutes, the examination was positive.
  • 20. Ventilation system
  • 21. Air TightnessProff. RizaAtiq
  • 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.
  • 25. Traffic in SolarCity
  • 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.
