Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.
CHALLENGE - Highly efficient use of hot gas and waste heat in air/water heat pumps for plus-energy buildings and quarters
CHALLENGE aims to further develop the system concept for air-to-water heat pumps in such a way that they can be used efficiently and without the above mentioned negative effects in densely built-up urban areas. In concrete terms, validated simulations and a functional model of the overall system on a laboratory scale are to be used to demonstrate that the concept can save 10% of electrical energy, reduce the noise of outdoor units in summer to a minimum and prevent the formation of local heat islands.
Characterisation of material parameters as basis for innovative processing methods and products made of large dimensioned wood aiming at economically sustainable use of Austrian timber resources "XXL-Wood"
Facing the problem of decreasing demand for large dimensioned timber, investigations are carried out concerning certain properties like strength and fibre characteristics. Due to the data it is possible to create a model about the variability of special properties of a stem. Based on the model new concepts for optimised processing and products will be developed.
Based on promising preliminary work feasibility and recycling strategy of the modifying process shall be evaluated economically and ecologically.
The results of this project were to deliver the basics for chemical process engineering taking into account the requirements of sustainable development. The proposed results will have to be in conformity with ecological, economic and social requirements for sustainability. Hence the processes will mostly be based on renewable resources.
Analyses of biochemical reactions causing colour changes during the hygrothermal treatment of selected hardwoods will lead to a model for defined and process-based colouration or maintenance of colour in drying and steaming processes. Based on this development the new drying and steaming schedules will be implemented in the industry.
The project CiQuSo aimed to develop, evaluate and optimize concepts for solar energy systems to provide energy for buildings and cities. The applicability of the developed methods and concepts were shown as an example at Itzling, a part of Salzburg city.
Development of an intelligent district cooling concept and alternative solutions for heat rejection from central absorption chillers at the example of the neighbourhood TownTown in Vienna.
City Dialog - Evaluation of future research topics for the "city of the future" through stakeholder dialog.
The integration of key stakeholder views allowed an extensive evaluation and prioritisation of research topics for the "city of the future". The discussion had been organised in workshops with stakeholder groups (public administration, science & research, residents).
To assess the energy performance of urban planning projects in early design stages with low input and evaluation effort within the project CityCalc, an easily applicable planning and evaluation tool has been developed.
CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen
CityStore pursues a first-of-its-kind, innovative approach on spatial location of storage needs and potentials. This includes the evaluation of concrete challenges and prerequisites as well as the identification of useful storage technologies and capacities. Model calculations for the model cities Graz and Weiz will be carried out. If, and to which extent, the results can be generalized will be investigated in the Follower Region South Burgenland. The results should enable optimized planning and realization of urban energy storage facilities – thereby enabling targeted investments in energy infrastructure to achieve (local) climate and energy targets.
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.
Climate neutral buildings from the period of promoterism - ways, potentials and possibilities of implementation
The focus was on the goal-oriented and economic options, in order to achieve a CO2-neutral energy supply and hermetically sealed building envelope as well as to show high energy efficiency when using. On the other hand building protection regulations and the quality in use are to be considered.
Climate protection in Schools: a prototype for targeted oriented knowledge transfer for students on the basis of energy efficient buildings
The saying "Was Hänschen nicht lernt, lernt Hans nimmermehr." which can be translated with the English saying "You can´t teach an old dog new tricks." especially applies to the issue of "climate protection" in general. Therefore children must be made aware of the importance of the subject from the beginning on in order to live their life efficiently and environmentally friendly. Based on a research and on an evaluation of existing teaching materials teachers and students will develop, how students understand the topic "climate protection" with a focus on "building and living in the future" the easiest way.
CO-MOD - Increasing comfort and energy efficiency through improved lighting and air quality in schools - implementation through modular EPC-models and ESCO-networks
In general local educational institutions such as schools and kindergardens have a high average demand for improved comfort and energy efficiency improvements. CO-MOD develops a flexible, modular concept (with provider networks, various financing options incl. "Grandmother"-Energy Services, contract modules) that can also respond to the individual circumstances of smaller objects.
CO2 neuBau - The CO2-neutral Construction Site: a Contribution to the Climate Protection by the Austrian Construction Industry
Identification of all direct and indirect CO2, respectively, GHG emissions generated at construction sites. Analysis of the framework conditions and technologies towards demonstrating the options for their control. In parallel, added values, such as cost-benefit advantages of a CO2-neutral construction site, are outlined and quantified.
By means of optimization of the production of vegetable dyes and dyeing technology, the vegetable dyestuff "Colors of Nature" will achieve market maturity. In co-operation with farmers and companies of the textile, food processing and wood working industry there has been developed a competitive product throughout the value chain, which will not only yield an ecological advantage, but also generate regional creation of value.
Evaluation of the quality and efficiency of state-of-the-art installed solar combisystems, potentials for improvements and measures to increase the quality
Ventilation systems for dwellings can be more efficient in terms of cost and energy, if the air guiding concept with cascade principle (overflow of air from sleeping rooms into living room). In this project, the planning principles had been developed and published in practice guidelines.
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.
