Artificial sun for daylighting evaluation of building models
Energy Efficiency and Indoor Climate
| Measurement | Exposition and shading studies of buildings and settlement models, daylight system evaluation and optimization |
| Standard | DIN 5034 |
| Measurement object | Models of buildings or settlements |
Technical data
| Light source | 85 halogen spotlights |
| Model table | Diameter 1.20 m; distance to specimen 6 m, gimbal mounted |
Special features
| Direct radiation | Narrow beam of lamps and filtering with honeycomb material lead to an almost parallel insolation on the model table (2° angle). |
| Automatic control | Software-based control of the relative angle of the model to the artificial sun to set any positions of the sun and diurnal cycles |
