Elly Heuss Knapp School - Renovation of the existing building and extension of the new building, specialist planning for technical equipment HLS in accordance with Part 4 Section 2 HOAI AG 1-3.8, service phases (LPH) 1 to 9
The contract comprises the technical planning of HLS technical equipment in accordance with Part 4 Section 2 HOAI AG 1-3.8
Performance Phases (LPH) 1 to 9:
- Plant group 1 sewage, water and gas plants,
- Plant group 2 heat supply plants,
- System group 3 ventilation systems,
— Plant group 8 building automation
A gradual assignment of services of LPH 1-9 is envisaged.
The Elly Heuss Knapp School (EHKS) is a primary school that consists of 5 buildings in total: The administration building marks the start of the school in the north, followed by three parallel, bar-shaped school and class wings. The gym and the sports field form the southern end. The five buildings are connected by covered corridors; schoolyards are located between the school buildings. The Elly Heuss Knapp School has been listed as a typical example of 1950s and 1960s architecture in Darmstadt since 2015.
The school is currently suffering from a significant lack of space due to changes in all-day care and the pedagogical concept. There is a space requirement for 4 classes/classrooms with differentiation rooms and an all-day area. A new building is to be built for these rooms. There is also a high need for renovation of existing buildings. This includes structural fire protection (lack of second structural escape routes for the classrooms on the 2nd floor) and accessibility issues.
Project objectives Technical equipment:
A. Project objectives water, waste water, heating, ventilation
The aim is to achieve systems that are simple, easy to operate and maintain.
The overall concept for the buildings should be evaluated in terms of energy, operational and economic optimization potential. In principle, investment costs for building services must be set in an appropriate proportion to their savings potential.
The required control technology should be kept as low as possible and be low-maintenance.
The new building is to be planned as a hybrid building. The building envelope is prefabricated in wood-panel construction. The TA must be integrated into the prefabricated elements.
heating
The aim is to achieve a high level of thermal comfort. For heating and ventilation, low-tech variants with a high share of renewable energies are to be striven for. A central temperature reduction at the heat generator is desired outside the useful life.
Ventilation and summer heat protection:
High demands are placed on air hygiene within the building.
Ventilation options must be provided in conjunction with window ventilation of sufficient size. Separate ventilation and deaeration of the toilet areas is desired.
,
Against the backdrop of changing climate conditions, special attention should be paid to winter as well as summer heat protection (e.g. shading, night cooling).
,
Drinking water systems
The drinking water regulation must be observed, legionella prophylaxis must be provided for. The necessary sampling points for drinking water testing and automatic flushing devices must be provided. Leakage monitoring and softening system must be provided.
