Syn[En]ergy: Development of Potential Synergy Effects between the Interdependency of Urban Planning goals and Photovoltaic Usage on Open Urban Landscapes
Open spaces such as parking lots, brownfields and some categories of recreation areas offer an underutilised potential for photovoltaics in urban regions. In the course of Syn[En]ergy an inter- and transdisciplinary approach potential synergies and conflicts with other use demands were investigated, a typology and practical solutions for selected areas with regard to requirements from economy, urban planning and design, legal as well social aspects developed, and then evaluated by stakeholders from enterprises, administration and the general public.
Innovative, dynamic control concepts shall be developed which enable (air) heat pumps in combination with PV- or renewable grid electricity to use the building mass of a multi-familiy house as heat storage. User acceptance shall be evaluated and possible business models shall be developed.
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated. The aim was to activate and use the thermal storage potential that is immanent in the building elements and thereby achieve solar coverage of the building's heat demand of nearly 100 %.
PowerShade - Development of electricity-generating shading solutions for energy-flexible buildings in urban space
The main goal of the cooperative R&D project "PowerShade" is the development of low-cost and universally usable electricity-generating shading solutions for energy-flexible buildings in urban space.
The aim of this exploration study is to explore a possible systematic change that will allow for a more universal application of Hook-and-Loop (or similar) fasteners in the construction industry, especially in building installation phase.

Die Synopsis ist eine drei- bis vierzeilige Beschreibung des Projektinhalts alsErgänzung zum Titel und nähere Erläuterung des Projekts.
"Gasthermenersatz" - Modular heat pump with environmentally friendly refrigerant to replace natural gas-based heating systems in large-scale residential buildings
The project "Gasthermenersatz" aims at developing, manufacturing, and testing a functional prototype of a decentralized, sound-optimized heat pump solution with refrigerant circuit modules connected in series or parallel. This renewable technology is well-suited to replace existing natural gas-based heating systems in large-scale residential buildings and to pave the way to carbon-neutral cities.
ÖKO-OPT-AKTIV - Optimised control and operating behaviour of thermally activated buildings in future urban districts
Development and simulation of scalable, distributed control strategies for the use of the storage effect of thermally activated components in buildings of future city districts for their energy supply by an energy centre.
Automated integration and assignment of exchange requirements between the design and simulation programs, based on the elaborated exchange information requirements, should enable continuous energy efficiency planning along the design phase.
The aim of this project was to advance the state of the art in the engineering of double-leaf building facades that facilitate natural ventilation while providing sufficient sound insulation. Realization of natural (window) ventilation is in some instances difficult due to a number of factors. Thereby, noise pollution (especially traffic noise) plays an important role. To address these issues, the project explored innovative solutions in terms of facade constructions for concurrent natural ventilation and noise control.
A specially developed simulation model is employed to ascertain the energetic potential of adaptive façade systems. The dynamic behavior of the physical properties of the adaptive façade system reacts to both internal and external changing conditions. The goal was the development of an adaptive façade, which helps provide maximum comfort for the building occupants with minimum energy consumption.
MehrWertStrom 2030 - PV-Community system - Exploring a participatory pilot project with regional added value for structurally weak regions
The "MehrWertStrom 2030" project analysed the legal, technical, organizational and economic feasibility of PV community joint venture facilities on multi-party buildings including the added value for structurally weak regions and developed innovative solutions related to organization, financing and realization.
URBAN STRAW - Fire protection conditioning of blow-in straw insulation material and its structural application for urban building classes 4 and 5
Investigation and development of fire protection conditioning of chopped straw blow-in insulation based on biogenic flame-retardants of similar building materials and their application methods. Use of the material as external thermal insulation in material-reduced prefab timber construction elements for urban building classes 4 and 5 up to 6 storeys.
Coole Fenster - Windows with shading optimising the trade-off between summery overheating, wintery heat protection and adequate illumination
Windows with their associated components such as sun and glare protection are optimised as a holistic building equipment unit regarding different seasonal requirements in light of the climate crisis. The results serve as a basis for new developments in the window and shading technology in order to provide summery and wintery heat protection as well as adequate natural illumination over the year.
The project deals with the analysis of Blockchain technology in the context of renewable electricity producers and flexibility as enabler for innovative service concepts, tested in the innovation-lab “Energie Innovation Cluster Südburgenland”. The goal is to find new and efficient Blockchain-based solutions for services in energy management and trading in a local level.
Pre-cast cantilever balconies represent a particular problem in the thermal renovation of buildings. The central goal of this project is the development of practical and cost-effective mounting solutions for the thermally decoupled reconstruction of balconies on building frontages and achieving a significant increase in the energy performance of the thermal renovation measure.
Within the scope of the project a photonic cooling approach was investigated and evaluated in terms of feasibility and cost efficiency for building applications. In particular cost-efficient photonic surfaces and concepts were investigated which need to have a high reflectivity in of the incident solar radiation (>97%) and a high emission coefficient within the spectral range of 8 – 13 micrometer in order to enable the emission of heat into the sky.
This project targets the further development of windows with integrated vacuum glazing. Such glass products regularly feature a very low Ug-value, and their dimension is in comparison to insulation glass thin and light. As such, these products offer a new alternative for highly-insulating window constructions, and thus also for energy-efficiency measures in buildings. The project is based on the findings of a previous exploratory project (MOTIVE) and focuses on the construction of functional prototypes of vacuum glass windows together with business partners.
