Energy Efficiency and Indoor Climate
Measurement | Comparative measurements of different building and heating systems under real weather conditions with emphasis on residential buildings |
Measurement objects | Insulation systems, set ups of walls, windows and roofs, radiators and underfloor heating systems, component and control concepts, intelligent control concepts in smart grids, demand-based ventilation systems, sun protection systems, heating systems |
Floor area | 82 m² (each floor) |
Layout | Ground floor: 6 rooms Attic: 2 rooms |
Roof pitch | 30° (orientation south and north) |
Full size research under real climate boundary conditions | Two structural identical single family houses for comparative examination of different concepts concerning energy efficiency, thermal and visual comfort |
Flexible façade design | The structure of the houses has been engineered to admit the replacement of all exterior components on the ground floor. |
