| Primary school with crèche and sports hall in the Riedberg district of Frankfurt/Main building owner Stadtschulamt, represented by Hochbauamt Stadt Frankfurt/Main competition 2001, 1st prize period of construction 09/2003 - 10/2004 total area 8785 m² total volume 40347 m³ |
The primary school and crèche in the Riedberg district of Frankfurt/Main was the one of the first schools in Germany to be constucted entirely as a passive building and was awarded the “Quality-Proved Passive House” certificate by the Passive House Institute in Darmstadt. The building complex, consisting of a primary school with four classes per year for 400 pupils and a day-care centre for 100 children, or five groups, was one of the first schools in Germany to be constructed completely in the passive-house style. The accompanying sports hall, covering a total area of 44 x 22 meters, was also built as a solid construction with comparable system components with an excellent low-energy design. |

The new building is situated on a plateau with views across the Frankfurt skyline to the south. Due to this exposed location, the school was designed as an angular arrangement, its rear being closed to the northeast and northwest while opening out towards the south and southwest towards the neighbouring Bonifatius Park. Thus providing panoramic views across the landscape and enabling optimum use of sunlight and heat. The deciduous trees in the schoolyard provide shade during the summer months while permitting sunlight to enter during the winter. Towards the north, the building complex has a rather closed appearance, protecting the classrooms from noise emissions from road traffic. |

Each of the three sections of the building – the day-care centre, school and sports hall – are equipped with separate entrances from the two access roads, the main entrance to the school forming a meeting square at the crossroads to reflect its public significance with regard to the developing new district. The eastern section of the building is staggered downwards over a length of approximately 8 meters along the descending terrain, making the individual entrances handicapped accessible and level with the ground at every stage. |

The entrance area is characterised by the projecting roof, a striking feature with a strong influence on the adjacent outdoor area. The structural configuration incorporates the landscape into the large, extensible foyer. The foyer can be interconnected with the assembly hall and the dining hall to form one large area that can be used for special events. The bright, light-flooded assembly hall also provides views into the distance and of the different levels of the building. All areas of the building are connected together via direct means of access. |

In addition to the conventional spatial programme, the school and day-care centre offer various rooms for all-day childcare: a kitchen with dining hall, rooms for supervised homework, pupils’ meeting rooms and group rooms for intensive supervision, a library and other multipurpose rooms. The sports hall to the south east with its connecting and spectator gallery, designed to be used not only for school activities but also for external use by local residents and clubs, is entrenched into the terrain so that it can only be observed from the higher viewpoint of the school through its green roof. The day-care centre rounds off the complex to the south west and toether with its group rooms opens out into the parkland that is being created. |

For ecological and tactile reasons, primarily natural materials were used in the interior. Linoleum was used as a floor covering in the classrooms and corridors, while the window frames and benches are made of wood. The coloured, non-bearing wooden façade resumes the theme of the interior materials. The landscaped roof of the sports hall underpins the impression of a “green space” school. The building levels are colour-coded and coordinated for guidance. The clear primary colours have a fresh and friendly appearance. |

A school is ideally suited as a passive house because the pupils already provide a considerable amount of thermal energy with their heat emissions, which in turn heat the classroom. Even in the case of temperatures slightly below zero – provided the walls and heat-protective glazing are insulated accordingly – the heat emitted by 25 pupils and one teacher is sufficient to heat the classroom of a passive-house school adequately. The outgoing air is fed via the corridors in order to heat them and extracted to a central location. The residual heat from the outgoing air is fed directly to the fresh incoming air by means of heat exchangers. To limit heat loss and to avoid overheating during the summer months, the proportion of window surfaces was reduced in accordance with the alignment of the building. |

In comparison with a school built using conventional methods, up to 90 % of energy costs are saved. A controlled room ventilation system with highly efficient heat recovery together with economical energy consumption ensures high indoor air quality and so provides an excellent learning environment. The use of a pellet heating system, a controlled mechanical ventilation system and corresponding heat insulation ensure lower operating costs and lower CO2 emissions. Within 30 years, around 1,000 tonnes of CO2 can be saved in comparison with a standard new construction. |
