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.
COP5+ - Further development of a heat- and cooling system with seasonal heat storage at the example of Central Europe´s biggest geothermal depth drilling field
The aim was to increase the overall energy efficiency of Plus-Energy-Houses by making the heat excess of summer available for use in winter. This was carried out by improvements of the technology seasonal heat storage to an intelligent overall system. The biggest geothermal depth drilling field in Central Europe has been established.
On the basis of our relieable CPC-collector SOLARFOCUS S1 we develop the CPC-lightweight construction collector to get more material efficiency and maximum output of solar hightemperature energy.
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.
In the multitude of digital possibilities, it is very difficult to maintain an overview, to assess trends and potentials, and to recognize correlations. This report therefore aims to describe the current state of the art and the market assessment of promising digital technologies. Information is provided on concrete use cases, added value and challenges of the respective technologies. The analyses presented serve to assess the potential and set the strategic course for the integration of the currently most important digital technologies in the construction and real estate industry.
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.
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 main objective of the key project "e80^3" was to develop high-performance renovation concepts focusing on plus-energy-buildings. Afterwards these concepts were realized in at least one or two demonstration-projects.
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.
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.
