Fraunhofer Institute for Building Physics
Solar simulator for large building components
Hygrothermics
| Measurement | Thermal load tests, spontaneous failure, temperature of building components, g-value (SHGC/total energy transmittance), fitness for purpose, aging behaviour, thermal expansion, fogging of closed glass façades |
| Standards | Alternative method to DIN EN 410, DIN EN 52022-3, DIN EN 4892 |
| Measurement object | Façades and roof components with opaque, translucent or transparent partial areas, transparent building components with light-directing elements, sun protection or shading facilities, also in interspace between the panes, glazing with integrated photovoltaics |
Technical data
| Irradiated area | 1 to 8 m² |
| Effective irradiance | 500 to 1200 W/m² |
| Sun elevation angle | 0 to 90° |
| Quality of radiation | Solar-near spectrum, mainly parallel beams, variable diffuse component up to 100 % possible |
| Installation of the specimens | Wall to roof (0 to 90° continuously) |
Special features
- The solar simulator reproduces almost all global radiation loads on building components in their original size and original mounting position. Smaller specimen can be irradiated with higher intensity, e.g., aviation
- Weather-independent test facility with reproducible boundary conditions
More information
- For long-term weathering testing and thermal load tests additional solar simulation facilities for sizes between 180 × 260 mm and 4 m² are available.
- Standard tests according to relevant standards for long-term weathering under combined exposure to UV-A radiation, temperature and condensing humidity or spraying are also possible in seperate test facilities on request.
