Challenges fort he cities of tomorrow with research issues referring to resource management, efficiency and technology development
The use of natural resources in long-lived products and buildings has led to the build-up of enormous urban material stocks. The present project analyses the potential of these urban mines to increase the resource efficiency of modern cities.
The research project Urban MoVe will investigate to what extent private-law contracts (e.g. mobility contracts, funds, urban development contracts) are suitable as municipal planning and steering instruments for mobility at residential locations based on best practice analyzes and implemented national practical examples.
urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy
The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.
The project "Urban wind energy" aims to create the basis for the assessment of roof-mounted small wind turbines (SWT) in urban areas. Therefore, methods for the characterisation of turbulent wind flow fields are developed and on the other hand the impacts of turbulent wind conditions with reference to selected turbulence indicators on the performance of small wind turbines are investigated. The overall aim of the project is to address the question how to evaluate sites in urban areas for the application of small wind turbines.
Urbane GmbA aims to explore and assess the potential of greenable area from building and obscured stock (vertical and horizontal areas) in Vienna, to apply currently available survey instruments and to show research and development needs.
UrbanEnergyCells - Requirements for the implementation of energy cells in future energy system designs
The transformation of the currently hierarchical electricity system into a renewable, decentralized electricity system poses major challenges for the actors in the energy industry and society. Most of the installed decentralized renewable energy sources are installed in rural areas, due to easier legal implementation and shorter decision-making pathways. However, the energy density in urban areas is significantly higher, resulting in a transport of electrical energy to the consumption centers.
URSOLAR provides decision makers with a roadmap for the integrated use of solar energy in urban environments. The roadmap shows, how photovoltaics- and solar-thermal installations can be used in an ecological, economical and socially optimal way whilst considering legal requirements as well as infrastructural conditions in typical city quartiers and stakeholder interests.
Use of thermal cooling technologies and optimal combination with other heat energy consumers to use during summer the available district heating based on renewable energy sources: example of the municipality of Mureck
Optimal use of heating energy from a biogas CHP in the municipality of Mureck through demand side measures; the multifunctional energy centre Mureck on the way towards thermal air-conditioning: Multi-Mukli
The UsersTCP provides evidence from socio-technical research on the design, social acceptance and usability of clean energy technologies. Users play a central role within energy systems. The findings will support political decisions for a clean, efficient and safe energy system.
Using buildings as energy storage - Monitoring project: Detached house H and detached house F Energy source wind power – Energy source solar power
Monitoring and comparison of performance of thermally activated building components in two similarly built, inhabited detached houses with different energy sources (wind and solar power). The functionality of energy supply through wind power or solar energy will be investigated as well as the verification of the practicability of self-regulating system control due to building temperature behaviour. The results provide an insight into the calculation assumptions, system control and feasibility of the smart grid technology.
Using the Sustainability Balanced Scorecard (SBSC) at operational and inter-operational level (ÖKOPROFIT) for reconciliating the systems of objectives in the realm of sustainability
Further development and implementation of the sustainability scorecard for definition of sustainable objectives on cross-company level (local agenda 21 project ÖKOPROFIT) and company level. Comparing the target systems.
Valuation models for future energy clusters considering market, technology and policy uncertainty - Case Study Biomass
Market liberalization, technological change and increasing complexity of international policy processes (e .g. climate negotiations) necessitate new approaches to evaluating investments in an uncertainty and risk-augmented framework. This project developed valuation methods from financial theory - such as real options valuation and portfolio optimization - to quantify the relative competitiveness of bioenergy chains and total energy systems.
Knowledge consolidation of the exploratory project VIG_SYS_RENO; This project focused on the application of vacuum glass in existing casement windows for purposes of energetic performance improvement of buildings. Expected results include new insights about and a guideline for the application and utilization of vacuum glass products in existing window systems.
Ventilation and heating in passive houses: Comparison of variants in terms of thermal comfort and sustainability
This projects aims at systematic resarch on thermal comfort and the sustainability of heating passive houses with and without air heating. The results of the comprehensive investigation of different variants will provide valuable information for building developers, planners and for funding decisions.
VERTICAL FARMING - Investigation on requirements of a Vertical Farm-prototype development for crop plant production
In the center of interest stands the investigation of fundamental principles for a new building typology – the Vertical Farm. Urban vertical food production can contribute to more energy efficient cities by concurrently reducing land use. Substantial influencing factors to achieve these goals are intended to be revealed.
The project researches possibilities and potentials of highly efficient use of space through modern concepts of "stacked" functions and vertical production.
Production of natural gas substitute from biogas and grid-injection to the public natural gas grid on an industrial scale using the two-staged membrane separation process gaspermeation. Design and erection of the upgrading plant at the biogas plant Bruck/Leitha as well as monitoring and optimisation of the operational characteristics.
Preparation and initiation of the implementation of a Virtual Green Power Plant based on renewable energy sources at the Program Responsible Party of oekostrom AG - The conception of a power utility within the Austrian power market.
For the cost efficient and lasting energy supply from ecological sources, wind, photovoltaic and biomass have to be integrated in existing grids. New methods for DSM and virtual power stations are investigated, to improve the control behaviour.
