smartEXT - extended application boundaries for proven passive house technology
The present study aims to explore the application options for compact units (ventilation devices including micro heat pumps, developed for passive houses) in low energy buildings. Compact ventilation units for heat recovery, heating and domestic hot water shall bear the basic heating load, whereas peak loads shall be covered by newly-developed auxiliary heating equipment combined with intelligent control algorithms. This allows increased energy efficiency as well as cost effectiveness together with higher living quality and lower ecological load.
Indicators for urban areas – for construction, operation and mobility in climate-friendly areas
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.
Evaluation of temperature differentiation on a room-by-room basis in passive house apartments
In the passive house Utendorfgasse a room–by-room temperature control was installed in 11 apartments. The experiences were evaluated from a technological and from a sociological point of view.
An innovative approach for facades with optimised noise protection and natural ventilation
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.
CombiSol: solar combisystems for houses, state-of-the-art and potentials for improvements
Evaluation of the quality and efficiency of state-of-the-art installed solar combisystems, potentials for improvements and measures to increase the quality
Sol2Pump - High efficient combination of solar thermal plants, photovoltaic and heat pumps
Targeting a high level of decentralised energy supply on basis of renewable energy, the project analysed the possible combinations of solar thermal energy, photovoltaic and heat pumps. The project aimed to maximise the domestic energy supply due to utilisation of the building as short term energy storage. In addition to that, several optimisation measures had been developed. The impact on the energy supply and demand will be economically assessed through life cycle costing. On this basis, the potential load transfer and the use of this kind of systems had been evaluated in combination with smart grids.
Cross building energy exchange: legal and economic framework and influencing factors (GebEn)
Using an interdisciplinary approach, the legal, technological and economic aspects of the cross-building exchange of heating and power were analysed separately within a methodological framework which includes different system configurations relevant to the specific situation in Austria.
solSPONGEhigh - High solar fraction by thermally activated components in an urban environment
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 %.
Eco.District.Heat - Potentials and restrictions of grid-bound heating systems of urban areas
Aim of the project Eco.District.Heat is to provide strategic decision-making support that enables Austrian towns and cities to deal with aspects of grid-bound heating (and cooling) systems in accordance with integrated spatial and energy planning from a holistic perspective when elaborating urban energy concepts.
Increase of in-house consumption by building clusters and active storages (Eigenlast Cluster)
The project involved the evaluation of the significance of new approaches for the increase of in-house consumption of solar energy (electric energy and heat) of buildings in Großschönau, which are already equipped for such measurements. The existing municipal buildings, commercial buildings and households are aggregated to form virtual building clusters. Subsequently, the clusters were analyzed according to their in-house consumption with and without the usage of batteries and H2 storages. The economic analysis of this concept derives from a regional implementation plan for further industrial research.

Enhancements of SOLrose with respect to the state oft he art: attractive design for frontage integration, serial production of system modules, distribution and assembling.
GEMA – Assessment of the performance of energy-efficient demonstration buildings
In GEMA, the project team will study and analyse the energy consumption of at least 10 commercial and residential buildings in Austria, which include innovative technologies or concepts for minimising their energy requirements. The results will allow for the potential optimal performance in terms of energy, environmental and social indicators of buildings in future construction projects.
Bi-directional integration of buildings with heat sources in thermal networks
This project analyzed the integration of decentralized heat sources into domestic heat grids technically, but also economically.
Operational and maintenance costs in passive houses and low energy houses
How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.
PEAR – Test facility for energy efficient automation and control of buildings
The energy demand calculated in the design phase often differs from measured values in the actual building operation. This projects reviews building automation and operation by presenting a solution how to assess energy efficiency of control strategies in the fields of air conditioning systems, concrete core activation and free cooling. The results are implemented in the demonstration building "Post am Rochus".
SpeedReg - Prompt quality assurance of the commissioning process of buildings
The focus of the project is on quality assurance within the commissioning process with the aim to speed up and to improve the operational adjustment of newly constructed or comprehensively renovated buildings. The fragmented know-how which is hardly accessible for the relevant target groups will be consolidated and elaborated in the form of a practice guideline which will be directly applicable in commissioning processes in practice. In this way the project contributes to the development of a common, well-established standard for quality assurance within the commissioning of buildings.
