The motivation for developing the project "Clay Passiv Office-Building Tattendorf" was the dissatisfaction with the situation of a great difference in the state of technology in three fields relevant to the research project: 1) sustainable production of energy , 2) sustainable energy conservation technologies and 3) use of sustainable building materials.
Comfort ventilation plus+: First time development of high efficient comfort ventilation systems that enable demand-control of room-wise airflow for new buildings and refurbishment
First time development of innovative components for comfort ventilation systems used in new buildings and renovation that enable demand-control of air flow room-wise. The outcome is a considerable reduction of the primary energy balance and a sustainable solution of problems concerning the discrepance between satisfying humidity and very good indoor air quality within the heating period.
CoolAIR - Predictive control of natural nighttime ventilation and daylight-optimized shading for passive building cooling
Natural nighttime ventilation and daylight-optimized shadowing are high potential approaches to efficiently and economical cool buildings. Nevertheless, the full potential cannot be acquired, since, if at all, such behavior is manually initiated by users. Goal of this project is the development of an automated, self-learning system that can assess the full cooling capabilities and establish an alternative to conventional air conditioning systems.
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.
Cooling LEC - Energy-flexible buildings by controlling cooling systems via unidirectional communication in local energy communities
As a result of climate change and the rise in temperature, especially due to the increase in active cooling systems, especially at low-voltage level, new challenges are being posed to the electricity system (in particular to the distribution network). Due to the high electrical input of active cooling units and the high density of plants, which are sometimes operated uncoordinated and at unfavorable times, leads to peak consumption in the system. The project Cooling LEC therefore has as its overall objective the development and demonstration of a central control / intelligence of decentralized active cooling systems by further developing the unidirectional communication of ripple control systems to create energy-flexible buildings in the sense of the new approach of "Local Energy Communities" by creating a "special tariff". Ripple control systems have been established for many decades and are available and proven by all energy suppliers. The upscaling potential is very big.
New materials and installation methods for diaphragm walls will be investigated in laboratory and field tests in order to improve the thermal properties of the construction elements. Additional numerical and ecological aspects are considered to ensure an energetic enhancement of underground constructions such as underground garages or thermal energy storages.
Development of a "Light Well" for daylight transparent, highly energy-efficient, multi-story buildings
Daylight supply of multi-story buildings with the help of rooflight openings. Reflecting vertical ducts transport light down to the lowermost floor. The idea promises new building structures with daylight transparency and high energy-efficiency that have a minimal demand of artificial light and cooling at optimal comfort.
Improvement of operational parameters (efficiency, quality of current waveform, reduced size and weight) and reduction of manufacturing costs
Based on experience with low-energy-windows, a solid wood window is being developed, which meets passivehouse-standards.
Development of affordable building equipment and services for future "Energy Plus houses" (Plus-Hybrid)
"Plus-Hybrid" integrates knowledge and experience from current activities and complement them by adopting a holistic approach, considering the intelligent interconnection of components as well as managing the planned efforts and human resources in time. The goal of this project was to develop affordable building equipment and services for future "Energy Plus houses".
Research on the influence of collector hydraulics, piping and the arrangement of plant components on the stagnation behaviour of thermal solar systems.
E.Vent – Efficient, cost-effective and low-maintenance central ventilation systems for multi-family housing – Design, operation and fire protection measures
Die Synopsis ist eine drei- bis vierzeilige Beschreibung des Projektinhalts alsErgänzung zum Titel und nähere Erläuterung des Projekts.
The major objective of the project EnRiMa was to develop an internet based decision-support system (DSS) to enable operators of public buildings to increase the system efficiency as well as to reduce the CO2 emissions. The DSS can be linked to existing energy management systems as DESIGOTM. The University of Applied Science Burgenland, Campus Pinkafeld, and ENERGYbase, Vienna, have been used to test and calibrate the EnRiMa DSS.
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.
Evaluation of mechanical class room ventilation systems in Austria and generation of a planning guideline
Accumulation of technical solutions and practical experience of schools (kindergarten) with mechanical ventilation systems and identification of how pupils and teachers accept the systems.
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.
As a contribution to the reduction of CO2 emissions, the project aims at upgrading existing heating networks by adding new devices, so-called exergy trafos, to the heat-exchanging transfer stations. These are driven by district heat and provide heating and cooling, as well as a reduced return temperature, as a service.
User behavior is a key factor for the energy consumption and the actual energetic performance of a building. A new type of user feedback system will be investigated in this research project. Users provide feedback on the sensed room quality. The data obtained by the feedback system are used to optimize settings of building services in order to improve the energy efficiency and the comfort in the building. A basic proof of concept of this system will be undertaken by means of two use cases.
In the course of the project FFF-TaliSys novel daylighting systems based on freeform surface technology were developed and implemented into functional models, thus, innovative systems that solve the contradictory requirements of daylighting systems.
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.
