Planning services for the replacement new building of a hoard building in Hermsdorf — lot 04 (TGA ELT).
Hermsdorf is a village in the municipality of Hohe Börde and is located in the Magdeburg Börde. The village is conveniently located between the regional upper centres of Braunschweig and Magdeburg, 2 km from the Irxleben junction of the federal highway and 4 km from main road 1.
New-built settlements on the edge of the old village and single-family houses on the slope of the idyllic Gersdorf boiler have almost quadrupled the population of Hermsdorf since the turn of the year. Other focal points of the first post-turn years were the development of large-scale commercial parks in the immediate vicinity of the A2 and the construction of the “Elbepark” shopping center. A large number of medium-sized production and service companies have settled here. The village has been pushing for the expansion of the inner village centre for 10 years. Renovated streets lead through the old village to the “New village centre of Hermsdorf” with the Kita/Multi-Generation House complex opened for cultural purposes in 2011, the Börde primary school, the youth club, the nursery and the new sports hall.
The current hotel “Adventureland” is a 2-½ storey building and is located in the immediate vicinity of the Börde Primary School Hermsdorf and is part of the nursery “Adventure Land” Hermsdorf. The building dates back to 1890.
175 children are currently looked after in the nurse in 8 group rooms. The group rooms and car washes do not meet the requirements of the current guidelines. The cramped space situation of the existing hoard building only allows an operating permit to take care of max. 114 children. The current operating permit therefore only exists through an exception authorization with shared use of the school building.
The group and laundry rooms are located on the ground and upper floor.
The second escape route from the upper floor is via a steel staircase.
The basement houses the house connection room and the heating system as well as storage rooms.
Barrier-free use of the building is not possible. The outer shell (exterior walls, ceiling to the basement floor, roof, window) is insufficiently insulated. The home services installation is outdated. There is a high energy and general need for renovation. The building was last renovated in 2006.
Due to population growth, the need for places in daycare facilities is increasing. The spatial capacities in the hotel are exhausted. Spatial expansion of the 2 1/2 storey building is difficult within the existing building envelope. An extension of the existing building cubature would therefore be essential. The building, built in 1890, cannot 100% meet today's requirements in terms of thermal protection, fire protection and requirements that are placed on the room program.
As a result, an extension of the building at the current location was considered. A solution for the overall use of the object including extension was developed.
This solution is uneconomical compared to a new building.
Therefore, the replacement new building of the hoard “Adventureland” at the “Mittelstraße” location is planned diagonally opposite the primary school, behind the new sports hall and the basis of the application. In the future, 200 hoard children will be looked after there.
planning
Due to the aforementioned shortcomings, the replacement of a hoard is planned.
For the replacement new building, the municipality provides an undeveloped property at the “Mittelstraße” location.
The advantage of the replacement new building is that children can continue to be looked after in the existing nurse until the new facility is completed.
You save cumbersome and costly interim solutions. The new hoard building completes the new village centre excellently and underscends the entire functionality of the modern educational location.
space program
The replacement new building was designed according to the needs of 200 hoard children with 6 group rooms, 2 homework rooms, 1 room as a support group and a language therapy room in clustering formation. There is also a children's kitchen as well as sufficient movement and play areas with multifunctional uses. This also allows pedagogical concepts to be integrated into the planned spatial structures that combine school and hoard use.
The building is built as a single-storey building with a relay level.
The rooms are spread over 2 levels and are accessible barrier-free. In order to ensure better distribution of incoming hoard children, 2 separate entrance areas with sufficient movement space were provided.
The building plot is the elongated cubature of the new building. The ground floor houses staff rooms, offices, house junction room, cloakroom, toilet facilities and a group room in the northern part.
In the southern part there is another group room, support group room and speech therapy, as well as a cloakroom and toilet facility as well as the elevator. Group and homework rooms with the corresponding toilet facilities are planned on the upper floor on the left and right.
For floors, sanitary rooms with washing facilities and toilets are assigned in the required number according to the guidelines for the construction of daycare centers in the district of Börde. Material spaces as well as built-in wardrobes are also available as storage options.
The group rooms have a direct exit to the play area, so it also serves as a second escape route. A green atrium for the children is set up in the centre of the hoard. The relay floor offers a spacious outdoor playing area.
Structural and energetic measures
1. Components (energy and CO2 saving)
The external components (exterior walls, floor plate, roof) will be insulated in accordance with the requirements of the new Building Energy Act 2020.
The windows are given double glazing with additional shading on the south side.
construction:
Base plate: reinforced concrete floor slab
Floors: Floors with floating screed (insulated)
Walls: solid sand-lime brick walls with 16 cm insulation material on the outside (EDVS)
Interior walls: solid sand-lime brick, partly from drywall
Windows: double insulated glazing
Slab: reinforced concrete slabs
Roof construction: flat roof reinforced concrete ceiling, plastic sheet as hard roofing
2. Creating accessibility
The building is built barrier-free in accordance with §49 of the building code of the state of Saxony-Anhalt. The ground-level construction creates barrier-free accessibility. The staggered floor is accessible via a lift. The required movement areas are fully adhered to.
A barrier-free toilet is set up for visitors, which can also be used by other people if necessary.
The hotel is generally not planned as an integrative institution.
3. heat supply
Heater:
— installation of a gas-supplied absorption heat pump with integrated condensing boiler to cover peak heat load for outdoor installation,
— air as a renewable energy source and natural gas as the primary energy source,
— transfer of heat via underfloor heating,
4. Venting and venting:
Installation of single-room venting units (exhaust units) for the interior toilet and cleaning supplies rooms. The heated supply air is backflow via the on-site door air grilles.
installation of ventilation units with heat recovery, wall installation max. 100 m
Devices with humidity and CO2 control in the children's lounge and group rooms.
5. Energy-efficient lighting
The use of LED lighting is planned in all rooms, the circuit is carried out
In the hallways and sanitary areas via presence detection and light incidence.
This requires a more frequent switching cycle than in the conventional circuit type, but it is easily achieved by the more economical LED luminaires with over 50,000 operating hours.
The starting phases of previously usual fluorescent lamps are also eliminated. LED lighting is immediately available 100%.
The LED lights used reduce energy consumption by up to 85%.
This ensures energy savings and longer lamp life, which is noticeable in the reduction of operating costs.
The components for emergency lighting are generally designed with LED technology.
Safety devices:
Emergency lighting and an internal house alarm system with networked smoke detectors are provided for escape routes.
precabling for data network
Pre-cabling is provided for the data network in costs. The building will be fully equipped with Wi-Fi access points.
The services up to service phase 3 (draft planning) have already been provided by the planning office A + I planning office Seidl & Dr. Heinecke has been provided. The planning office will also participate in this tender.
The measure is to be funded within the framework of the urban development funding programme. Appropriate applications were submitted by the municipality
High Börde.
