Solar Thermal Polymer Collectors with Overheating Protection

On the background of increasing costs for the main materials of solar thermal collectors polymeric materials offers a significant cost-reduction potential for all-polymeric flat-plate collectors in the low temperature field of application. However, as the long-term service temperature of cost-efficient plastics is limited for potential applications in solar absorbers an appropriate design including overheating protection is essential. The stagnation behaviour may be controlled by thermotropic layers. Such layers change their light transmission behaviour depending on the temperature. Development objectives for such layers were calculated by theoretical modelling.


Cooling retrofit concepts for offices and administrative buildings - COOLSAN

The operation of ten thousand Austrian office and administrative buildings ensures an enormous annual consumption of energy, where climatisation plays a central role. The cooling in office and administrative buildings in the European Union show a demand of 193 PJ, which is a crude oil equivalent of 4,608 million tons (EU, 2000)...


Integrating Environmentally Responsive Elements in Buildings (ENERBUILD)

The energy needed for heating, cooling and ventilation of buildings in the industrial countries represent over 30% of the entire primary energy demand. The building sector is therewith, next to the sectors “transportation” and “agriculture”, one of the main contributors to the greenhouse emission CO2. These facts and the goals in the Kyoto agreement show the importance of the identification of sustainable solutions for the building sector, which will long- to middle-term considerably reduce the emissions that arise from the operation of a building.


Development of an interactive vocational Web training tool for the take-off of the buildings DIRECTIVE 2002/91/EC (EEBD)

The building sector presently covers approximately 40% of the total energy demand in the EU. This energy demand can be reduced to 22% through implementation of relevant saving measures, if the economical frameworks are advantageous. These figures clearly show the importance of working active with “the increase in the energy efficient in buildings”. Important, legal frameworks shall be created through the implementation of the EU building directive.


Systematic renovation of social housing

This project treats a global renovation of a residential estate built in the 1960s in the context of council housing in a laggard region. The point is to optimise the renovation in all partitions which include habitation with a systemic approach in an interdisciplinary team.


PROCESOL II - Solar thermal process heating coupled with heat recovery technologies in industrial applications

The aim of the project is to elaborate basic knowledge of the design of solar thermal plants for process heat generation combined with heat recovery measures. The knowledge shall be transported to the target group of HVAC designers, installing companies and production companies in the participating countries Austria, Belgium, France, Germany, Greece, Portugal and Spain.


Promotion of "sustainable cooling" in the service building sector (KeepCool)

The overall goal of the project is to implement activities that reduce the negative impacts from increasing cooling demand in Europe through an increased market penetration of sustainable cooling approaches and technologies. A “preliminary definition” of sustainable cooling consists of the following elements: reducing heat load; minimizing the electricity consumption; increasing the use of renewable energy sources.


ST-ESCOs - Development of pilot Solar Thermal Energy Service Companies

The actual problem faced by this project is that although solar thermal applications are technologically mature and economically advantageous in the long term, they have still little penetration in the European market, with respect to their potential. One of the main reasons is that end users (especially for large systems) are still reluctant to face the high initial investment cost and doubtful for the reliability and durability of solar installations.



New Generation of Solar Thermal Systems.


SolProBat – Development of a Methodology for the Integration of Solar Thermal Process Heat in Batch Processes

The Austrian food, textile and chemical industry show a high potential for the generation of solar process heat. This was shown by the project “PROMISE” performed within the initiative “Fabrik der Zukunft – factory of tomorrow” of the Austrian Ministry of Transport, Innovation and Technology. Production processes are run in batch operation in many cases. A solar thermal process heat plant produces energy whenever the solar irradiation is high enough and does not take the production scheme into consideration.
