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.
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.
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.
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.
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.
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.
Solutions for expandable modular solar supported heating networks are developed for new settlement areas, which are established in several phases during the construction. This modular design should open possibilities to adapt the heating and the solar thermal system.
The Austrian district heating systems with a total length of more than 3,400 km and more than 13,000 GWh heat generation per year, show great potential for the adoption of renewable energy (seen as long-terms)...
The solar thermal system for public bath facilities in Darakhsh in Iran is a pilot project, which was carried out in cooperation with GREENoneTEC and AEE INTEC. Another 1000 systems are planed to be built.
