The integration of heat pumps can increase the cost effectiveness of existing heating networks and counter the high costs for the expansion of power grids at the same time. Aim of the project is to develop innovative business models for small and medium municipal heating networks with focus on synergies between heat and power market. Main focus is a heat pump pooling for several heat grids.

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.
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.
The aim of the project is to provide a "proof of concept" of a control loop and tool set for the management, optimization and evaluation of green and climate-sensitive urban (district) planning- The tool set consist of urban and open space planning instruments as well as climate simulations at different scale levels.
VisErgyControl - Integral control system for daylight and artificial lighting for high visual and melanopic comfort with minimized primary energy consumption
Within the project VisErgyControl an integral, simulation-based, energy-efficient open loop daylight and artificial lighting control system had been developed. The research project focuses on the visual and melanopic requirements of users while minimizing the energy consumption for heating and cooling.
"Biotope City" is an overall concept for the implementation of comprehensive urban greening with the aim of using the regenerative mechanisms of nature. With this approach, quality of life is to be comprehensively, sustainably and cost-effectively increased and resilience against extreme weather events in cities will be improved. The project aims to generate realistic components of a "construction manual" for the green city of the future, which are generalizable and transferable.
ecoRegeneration: Development of a "Merit-Order" in order to assess regeneration heat for geothermal probes within urban residential neighbourhoods.
In urban residential areas there are not enough active-cooled usages, to use the waste heat of the cooling process as required regeneration heat for geothermal probes; free cooling of the apartments is not sufficient. The project is developing various options (waste heat from commercial uses in the ground floor zones of residential buildings, by using waste heat of data centres, additional installation of heat generation systems for regeneration) within the urban settlement area, business models and is calculating life-cycle-costs of all solutions. The result should be a kind of "merit order" for regeneration heat.
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.
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.
Probing for PV façade systems made of lightweight plastic modules with reversible fittings for new and old buildings (PV-FAS_light + easy)
Probing for a new, simple, cost-effective and building-integrated PV facade system made of plastic PV modules through initial investigations for fixing technology, for building physics, for fire protection and for electrical engineering concerning the usability, the areas of applicability and the yield and application potentialfor new buildings and for existing buildings.
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.
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.
In the first phase of the project, the data source of the energy statistics will be analyzed. Based on the findings of the analysis a methodology on build up regional energy balances will be developed. The methodology will be integrated into the Senflusk tool and tested on five reference cities in Austria.
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 of innovative urban district heating systems by integration of long-term thermal storage, large scale heat pumps, large scale solar thermal installations, waste heat recovery and analysis and evaluation by simulation. The results of this project will provide templates for technology selection, system design and merit order for new urban district heating areas.

Smart Pölten 2.0 Holistic view on a Vertical Farm in preparation for a demonstration project for the city of St. Pölten
The city of St. Pölten forsees great potential in Vertical Farming with regard to the objectives related to the concept of the Smart City program - linking local food production, quality of life by reducing resource consumption. This has to be evaluated by combining Vertical Farms with existing living buildings. Eco-social and socio-economic considerations play an important role in this process.
