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.
DIM4Energy - Digital Information Models for the Planning and Optimization of Buildings and Urban Energy Infrastructure
Digital information models (DIM) are playing an increasingly important role in urban planning and decision-making processes, from individual buildings (BIM) to urban information models (UIM). For the planning and optimal operation of plus-energy neighborhoods, valuable information could be obtained from these existing models, provided the appropriate data sources and associated software tools are properly linked.
Development and coordination of indicators for energy and ecological evaluations of urban areas based on the Swiss 2000-Watt certification system. The results will be used for the development of a quality assurance system for urban areas similar to the klimaaktiv declaration for buildings and the e5 certification for communities.
KELVIN - Reducing the urban heat island effect via improving the reflective properties of buildings and urban areas
The aim of this project was to estimate the potential to reduce urban heat islands via low-tech measures such as the variation of the surface albedo, using the City of Vienna as an example. The project has also assessed the energy savings and greenhouse gas emission reductions due to the decreased energy demand for cooling as a result of such measures.

InnoGOK – Investigation of the energetic and ecological usability of solar radiation on urban spaces and paths
Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
The objective of this research project is to design a methodology for developing data and process models and to apply them by modelling selected MEP systems. A particular but not exclusive focus is put on the renewable heating technologies, e.g. heat pumps, solar heat and biomass as well as ventilation systems. The data and process models developed in this research project will be scientifically evaluated in two pilot projects. The models, the approaches taken during development and the project team’s experiences with the pilot application of the models will be disseminated openly.
The core of the project P³Power is the measurement technology NetDetection, which is able to detect the power consumption of a household from any point, e.g. a regular wall socket. Based on this technology a plug&play powerplant, consisting of photovoltaics and battery pack, is realized. The system is able to guarantee 100% self-consumption within flexible aggregates (from single households to whole communes) without any changes of existing infrastructure. The measurement technology will be implemented into digital hardware, evaluated comprehensively in lab and household environment and subsequently new energy service business models are developed.
SUPERBE - Potential of Superblock-concepts as contribution to planning energy-efficient urban quarters
The exploratory study SUPERBE for the first time looks into the applicability and potential effects of Superblock concepts in an Austrian urban context in order to assess their contribution to energy-oriented urban planning.
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.
ECC – EnergyCityConcepts – Development of a methodology and concept for the implementation of sustainable energy systems in cities by the example of Gleisdorf and Salzburg
In the context of this project two concrete model regions (small city Gleisdorf and urban city quarter Salzburg-Schallmoos) will be developed and tested with new methodical approaches (interdisciplinary urban and regional energy planning, modeling and simulation). An ambitious political commitment of both model regions is a 100% renewable or rather CO2-neutral energy supply.
Many traffic areas in urban environments are actually used as such only a small fraction of the time. Subject of this project was to investigate the possibility of using those areas by additional integration of photobioreactors for the production of biomass, integrating such systems to the maximum extent into the urban substance and energy cycles.
Manage_GeoCity - Development of a method for the coordinated management of geothermal energy in urban areas
Based on the urban region Graz a method had been developed for the coordinated use and management of shallow geothermal energy for heating and cooling as well as seasonal heat storage in urban regions. Ground water flow, different geologic conditions, heating and cooling demand, heat input from solar collectors and industrial waste heat and the possibilities of seasonal heat storage in the subsurface were considered.
The aim of the exploration-study for the urban region Bruck/Oberaich "Energieschwamm Bruck" or "Energy-Sponge-Bruck" was to establish clear and stringent basics for a flexible development of the future energy system. Therefore an energy development concept as well as a cadaster for short-term implementation measures had been applied. The structured, Bruck-based approach acts as framework for a general energy-conception-method, valid for small and medium urban regions with 10,000 to 20,000 inhabitants.
Intensified Density - a small scale densification strategy for the suburbs by using modular construction
The project investigated whether a small scale densification strategy for the suburbs / intermediary cities, using modular construction, and existing infrastructure on empty plots of land, can offer a competing alternative to not only the sprawl of single family dwellings but also to large projects.
PVOPTI-Ray, Optimization of reflecting materials and photovoltaics in urban environment with respect to energy balance and bioclimate.
Within the scope of the project PVOPTI_Ray the influence of reflection and energy balance on the performance of building integrated photovoltaics (PV) in complex urban environment have been investigated. Equally the influence of PV modules and of the energy conversion of solar energy at the PV module surface has an impact on micro climate and therefore also on pedestrians who are exposed to the radiation fluxes. This was also investigated.
Building Information Modelling supported compilation of a Material Building Pass; as a qualitative and quantitative documentation of the material composition of, and the material distribution within, a building structure. This project is a central milestone towards standardized, BIM-generated building material passes.
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.
CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen
CityStore pursues a first-of-its-kind, innovative approach on spatial location of storage needs and potentials. This includes the evaluation of concrete challenges and prerequisites as well as the identification of useful storage technologies and capacities. Model calculations for the model cities Graz and Weiz will be carried out. If, and to which extent, the results can be generalized will be investigated in the Follower Region South Burgenland. The results should enable optimized planning and realization of urban energy storage facilities – thereby enabling targeted investments in energy infrastructure to achieve (local) climate and energy targets.
With the city of Leoben as a use case this exploratory project will, for the first time ever, examine the spatial effects, synergy- and energy potentials of newly developed wide-span light-weight solar canopies for streets and squares in urban public space as well as their implications on the townscape, the image of the city and the city function.
