| Brush sealings were designed for the windows and balcony doors placed between the glazed sunspace and the apartments. |
| The sunspace becomes warmer than the outside air by absorbing short-wave solar radiation from the sun. |
| The sunspace or conservatory consists of a glazed enclosed area on the south sude of building. |
| Concrete absorbs daytime heat and emits it later, so that air from the sunspace will keep the house warmer in the evenings. |
| In many cases a sunspace is used as preheat for the ventilation air required by the house. |
| Care must be taken to avoid heating the sunspace in winter or the energy consumption will rise considerably. |
