1 Research and Testing Centre for Thermal Solar Systems (TZS) Dr.-Ing. (ITW) Solar- und Wärmetechnik Stuttgart (SWT) University of Stuttgart Pfaffenwaldring 6, Stuttgart, Germany Internet: \TZS_INF_E1.PPT TZS the largest testing centre and the largest university based largest research centre for thermal solar technology in Europe Source: ELSE06\TZS_1.CDR 2 1

2 Collector Tests outdoor tests indoor tests (solar simulator) performance prediction approximately half Solar Keymark tests up to now are from us 3 Reliability and Durability rain penetration high temperature resistance internal pressure for absorber mechanical load etc. 4 2

3 Store Tests hot water stores combi stores thermal store parameters 5 System Tests ISO (CSTG) ISO (DST) EN (Combi-Sys) system parameters performance prediction Solar Keymark Testing 6 3

4 Examples of R&D Project (1/4) EU-Project NEGST EU Project CombiSol Standardisation and promotion of solar combisystems IEA-Task 32 Advanced store concepts IEA-Task 33 Solar process heat Solar goes CFD Investigation of ageing behaviour of solar collectors Development of Test methods for solar cooling systems 7 Examples of R&D Project (2/4) standardisation activities related to EPBD directive, energy labelling, and eco-design directive EU Project QAiST: Quality assurance in solar thermal Further development of Solar Keymark Certification IEA Task 43: Solar rating and certification procedures Development of test and assesment methods for combined solar thermal and heat pump systems IEA Task 44: Solar thermal systems + heat pumps Further development of European Solar Standards 8 4

5 Examples of R&D Project (3/4) Monitoring and further development of large scale solar thermal systems with seasonal heat stores Polymeric materials in solar thermal - development of new collectors and systems Development of a modular water based heat storage concept New4Old: Integration of new (renewable) energy technologies in old historic buildings Development of a Solar Thermal Roadmap and a strategic research agenda, both German and Europe 9 Examples of R&D Project (4/4) IEA Task 42: Advanced compact energy stores Development of heat storage technology based on thermo-chemical reactions Development of a heat store based on a combination of water and sorption Investigation and further development of advanced heating systems for solar houses

6 ... and now a deeper look into some projects 11 Project Energy Labelling Activities 12 6

7 EU Energy labelling Household appliances offered for sale, must be accompanied by a fiche and a label providing information relating to their consumption of energy (electrical or other) or of other essential resources. For this appropriate test methods are required. For Solar supported gas-fired domestic appliances producing hot water : EN 13203: Part 3: Assessment of energy consumption We developed one of the methods in the standard 13 Advanced energy concepts for solar buildings 14 7
