Energy Globe 2001
Prize for renewable sources of energy and energy efficiency
The decision in STYRIA in the course of the AUSTRIAN PRE-DECISION has been made
| At the event of the Energy Agency - the 1st regular meeting(Stammtisch) for biomass-district-heating-operators- the award of the first three ranks of the Styrian pre-round of the Energy Globe AUSTRIA was carried out in the course of the gala reception: |
| Winner: Murecker Energy power circulation
Olympiad
SEEG Reg. Ltd.
|
 |
 |
Circulation 1: "From the field in the tank" - about 650 farmers, members of the association, grow rape and deliver it after the harvest to processing. The SEEG produces Biodiesel. Every farmer obtains his Biodiesel according to his amount of rape delivered (380 liter per 1000kg rape) and rape cake (621 kg per 1000kg rape), the Biodiesel operates the agricultural vehicles, the rape cake is a high quality protein fodder. |
| Circulation 2: "From the pan into the tank" - As the first worldwide and for a long time the only company, the SEEG produces Biodiesel from old cooking oil. Communities and gastronomy businesses can become members. They collect the old cooking oil according to their own developed logistics. Per 1000 kg of old cooking oil you get 850 litre of Biodiesel for your vehicles. More than 100 communities and Graz's public transport companies use this energy circulation. |
| Circulation 3: The district heating Mureck Ltd. operates a biomass-heating plant and currently caters for 150 objects using two MW-boilers at an acceptance performance of 5 Mw. The heating material is delivered by farmers and sawmill owners from the region. |
| Circulation 4 (in progress): As the worldwide first company the District-Heating Mureck operates a block thermal power-station which produces electricity out of the glycerine phase a barely combustible by-product. The motor developed delivers 2000 to 3000kW electrical current and 3000 to 5000kW heat. Additionally an aggregate is operated with pure vegetable oil. The current is integrated into the network of the city of Mureck. The entire heat is enough to provide for the current heat network of the city of Mureck from spring to autumn. |
| Circulation 5 (in planning): In order to safeguard a high heat acceptance service throughout the whole year the construction of a wood drying plant has been planned which can be used by farmers and wood-working businesses. |
| The ambitious target of the climate-association community of Mureck for a 100% own supply with fuel, electricity and heat from energy was started and should be achieved withing a few years. The five interlinked energy circulations secure the economical stability of the enterprise and are ecologically and sociopolitically of major importance for the entire region. They give security, comfort and quality and with the saving of 16.5 million kg CO2, an essential contribution to the environment protection. |
2. place: energy
partnership 2000 - construction project turning point
|
 |
| Since the accession of the "new home" to the association of climatic protection in July 2000, climatic protection has also been on the agenda in administration and office buildings: Energy accounting, opitimized transport logistics, ecological procurement, reduction of the motorized individual transport of the co-workers and motivation of all employees. |
 |
Energy partnership 2000: Certainly of importance are the climate-friendly measures in existing buildings. For the renovation of 75 objects an idea-competition has been announced in order to find a partner for optimized organisational, ecological and economical solution concepts. By 2010 75 objects, i.e. 319 houses with 2316 flats and covering an area of 146895 m² should achieve a 50% reduction of the CO2 emissions. |
|
Construction project turning point Gratkorn: In addition new building projects should also achieve climate-friendly goals. The block of flats Am Rinnergrund 2 in Gratkorn is planned as a low energy building, as a "3-litre house". According to TRNSYS-simulation an energy code of 30kWh/m²a should be reached. The building will be built in a mixed building manner with a reinforced concrete body with reinforced concrete ceilings and braced concrete disks as well as outer walls made of prefabricated wooden frame elements. Windows with triple glass insulation glasswork and outer structural components with U-values under 0.16Wm²K, a compact form, heat bond freedom and airtightness minimize the loss of heat, optimized windows facing the South make passive use of solar energy possible. Decentralized controlled ventilation and de-aeration with a winning back of heat, night heating with a calorific value boiler system and 75 m² solar collectors for water heating are house-technical completion of the building equipment. The shell of the house is finished, construction should be completed in August 2001 and should bring experience for further projects as far as code values, costs and user-acceptance are concerned.

3. place Bürobox 2000 |
 |
| The basic idea of an energy-optimized (zero-energy) building with utmost flexibility has been realised by a glass-only façade with a front laminated glass construction facing the south-west and through the use of geothermal heat via a three-sided building in the slope and the application of an earth register system, thus making it possible to do without a conventional heating system. Controlled ventilation with recovered heat, use of ecological building materials and CFC-free insulation materials, green roof areas, use of rainwater, light shafts and light management and a simple pipe structure complete the concept. |
