DAKTRis - Dynamic operational behaviour of absorption chillers in Trigeneration Systems
In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.
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
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.
COOLSAN - refrigeration concepts for office and administrative buildings retrofit

Technologies to enhance comfort and minimise energy requirements for air conditioning in existing office and administrative buildings. Possibilities to reduce the cooling loads and strategies for the use of passive cooling systems.
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.
Innovative regulation of thermal solar collectors
Research and development of the possibility of a "sensorless" regulation for thermal solar systems
Buildings of highest energy-efficiency with integrated renewable energy development
For the future supply of energy services the combination of energy efficiency, energy storage and decentralized use of renewable energy in buildings offers itself. The project identified dynamic potentials of possible active and passive energy yields of construction units with use of renewable energy sources, pointed future solutions to energy-efficient and ecological design of building construction-units and united all results to a signpost: From today's passive house to the energy-plus-house of the future.
Sunny Energy Building: ENERGYbase - Office building of tomorrow
Energybase is a showcase project in terms of energy efficiency and use of renewable energies realized by the Vienna business agency. With 7.500 sqm net floor area ENERGYbase provides space for innovative business and research and development on the field of green energy.
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.
New aluminium - sun collector

The development of a new aluminium - sun collector, where the working- fluid completely run through the absorber- area, to reach a higher efficiency.

Solarenergie Urban - Analysis and evaluation of the economic, energetic and architectural quality of urban solar energy buildings
This project developed energetic and economic optimised planning criteria for multi storey residential buildings for the integration of renewable energy systems in the building shell. The field of new construction and refurbishment had been investigated.
thermocollect: realisation of a plus energy building by a solar active facade system
The project demonstrates the application of a solar active facade system in the course of the renovation of an existing building in order to achieve the plus-energy standard. Moreover, the effectiveness of the system will be demonstrated on new buildings and transparent components as well. The final outcome will be a manual for the application and implementation of the façade system focusing on the segment of specialists and skilled labour.
Reduction of cooling requirements through optimized urban structures and processes and design optimisation in building design (smartKB*)
Based on a systematic listing of appropriate methods, recommended actions have been developed to reduce the cooling requirements in new or renovated buildings on three levels: a) optimization and use of appropriate urban structures, b) design strategies and passive measures for building concepts, c) reduction of cooling requirements through integrated planning processes.
ChristophorusHouse(CHH)

Multifunctional building in passive house standard - The building was designed as innovative high-quality passive house (wood construction) with the latest ecological building automation as a pilot project which is multipliable in a reduced respectively altered form in Europe as well as overseas.
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.
Facade Integrated Solar Collectors

Within the framework of this project system-, structural- as well as building physical basis theories should be elaborated, which will serve as a basis for constructional and aesthetically attractive solutions for the production of facade integrated solar collectors without thermal separation. The recyclability of the materials used and resource efficiency play a central role when it comes to the development of constructional solutions.
Sorption cooling and air dehumidification device
Solar-assisted air-conditioning in combination with comfortable controlled ventilation systems soon possible and affordably for building owners. With a new part DEC-systems should become acceptance.
Investigation into control systems for low emission, high efficiency biomass furnaces for heating residential and office buildings.

Through optimising the control systems of biomass heating systems, energy wastage and pollutant emissions can be reduced considerably. The goal of the project is first to analyse the possible savings that can be made in these areas, using the heat demand scenarios of different "Buildings of Tomorrow". The results of this analysis will lead to the development of an optimised control system which will be tested on a biomass heating system.
