IEA SHC Task 32 deals with advanced storage concepts for low energy buildings. In the project storages based on phase change materials are used in solar combisystems, in order to reduce the emissions and increase the efficiency of biomass- and gas boilers and to increase the solar fraction
Strategic optimisation of the regulation of air moisture through ventilation systems to reduce energy demand for humidifiers and dehumidifiers
For the validation of coupled room and building component simulations, an analytical solution of this unsteady problem was developed. Finally, a simplified method for determining the humidification and dehumidification demands considering a room's effective moisture capacity was developed.
Genotypes of energy plants adapted to the location will be identified and specialist crop rotation adapted to the location will be developed. The fermentation process will be optimised and the methane energy model will be advanced. The efficiency of the biogas production will be enhanced.
A concept for a cooperative forest fuel supply chain network for a large part of Austria (regions of Salzburg, Upper Austria, Lower Austria, Vienna) is developed in order to minimise transport-, storage- and total system costs while simultaneously increasing supply guarantee for the plants.
Direct Supply with Cold, Heat, Electricity and further Added Values Using Renewable Fuel for Stationary Fuel Cells
Fuel cells can use local resources and provide regional energy support if optimized. BIO-VISION leads to a demo-project.
Developing technical and business concepts and strategies for a sustainable power supply of supermarkets and local consumers - supply of heat, electric power and cooling energy on the basis of solar energy and solid biomass.
The biogas production from energy crops will be analyzed and optimized. Energy crops are grown in an environmentally friendly and sustainable crop rotation system. The project provides a secure basis of data for the biogas production and utilisation. Farmers will invest more into the biogas technology.
Selection and development of wheat and triticale cultivars particularly suitable for the requirements of bio-ethanol production also taking into account agronomic needs and properties, feed quality of mash and toxicologic aspects.
Compilation of guidelines and benchmarks for "best biogas practice" to ensure efficient biogas production. Constitution of an Austrian network including all partners in the biogas production cycle.
The Use of wind energy in skiing regions - Evaluation of the consume of electricity and dissemination of the results of the analysis
Main goals of the project are the analysis of the location Salzstiegl concerning the coverage of their own electricity needs with an already existent windmill as well as a following dissemination of the outcome of the analysis in form of a workshop for all ski lift carriers of Austria.
Production of natural gas substitute with a newly developed gas permeation technology. Optimization of the process with biogas from energy crops fermentation. Screening of new methods of online product gas quality control.
Preparation and initiation of the implementation of a Virtual Green Power Plant based on renewable energy sources at the Program Responsible Party of oekostrom AG - The conception of a power utility within the Austrian power market.
Development of an innovative business model for large-scale solar thermal plants for industrial and commercial companies
The current project has the aim to develop an innovative business model for large-scale solar thermal plants (> 500 m² collector area) for industrial and commercial companies. This business model offers the energy customer a contractually binding solution in a time frame of 3 to 5 years; also, the energy delivery costs are lower compared to conventional sources.
Obtaining, preparation and circulation of information about international evolutions in the field "thermal gasification of biomass" as well as management of different task emphases.
Based on the results of the concept "Energy-self-sufficient district Güssing", in this project feasibility studies for a self-sufficient energy- (model) -system on the basis of regional renewable energy sources in the district Güssing will be elaborated. Thereby the second step towards implementation will be done.
Austria with its large forests is a classical country for biomass use. Heating with split-logs is state-of-the-art for several years, and using combined heat and power systems for small powers to obtain self-sustaining households is an additional utilization.
Development of an optimal strategy to open up Austria's biomass potential until the year 2050. The optimal strategy maximizes the reduction of GHG emissions. Provision of an action plan for a temporal dynamic implementation of this strategy.
Development of a cost-effective cleaning unit, free of waste-products, for the upgrading of biogas to natural gas quality. Elaboration of the basis for a demonstration project injecting biogas into the gas distribution system of Salzburg.
Developing of a application for central visualisation of the energy and resource demand in a private household "ZENVIS"
The main focus of the research project ZENVIS is set on the analysis of the benefits provided by a "visualization device", which gathers the readings of energy and resource consumption (electricity, gas, water, heat energy and fuel consumption). This device ought to find its use in households and to allow the consumer to observe and to control his energy consumption.
