4th Place - Lecture - Seminar - Library Building for Homburg University Hospital


URBAN DESIGN CONCEPT

The new lecture hall extends the original concept of solitary pavillions in the park as a basis for the urban design. Its position on the allotted construction site is chosen to allow for the greatest possible spacing between constructions.
In this way two new spatial conditions emerge. The space between the two existing administrative buildings in the north and the new lecture building in the south, finished with benches and preexisting trees, serves as a park-like relaxation and rest space for students and instructors. The slightly remodelled terrains builds up the topography as a withdrawal from the street.
The newly created square between the existing assembly hall and new lecture building becomes the new urban center of the campus complex. It serves as forecourt to the auditorium and lecture hall and at the same time develops the link between the clinic and the university facilities. The west site of the square is bound to the new cafeteria by a row of trees and develops it into an edge for the square. The existing street is integrated into the square's design, the better to connect with the city and to give the square use beyond only the campus program.

CONSTRUCTION PRINCIPLE

The upper, partially projecting level will as spatial frame construction in steel four part system construction executed.
Upper or lowere flange of the rigid frame (IPE 300) absorb the vertical loads from the roof and ceiling. The blankets (d=30 cm) are manufactured as hollow body covers (eg system Cobiax).
The stabilization takes place through concrete wall sections and staircase cores.
The spatial framework is punctiform or line-supported in the system of a carrier grid.
Single and line loads are introduces into the subsoil with a foundation plate, which is reinforced in the area of point loads.

BUILDING MATERIALS

All visible walls and roofs are finished with concrete or masonry. The surfaces of these compontents are partially provided with a durable cement plaster, partially in exposed concrete. In the lecture halls, there are acoustic ceilings nad wall coverings made of oak.
The floor is of natural stone, oak parquet, linoleum or coated cement.

ENERGY CONCEPT

Facade

Vertical, partially rotated fins on the south side exterior are used to minimize glare. To prevent overheating during the summer months, a highly efficient solar control glazing is used. In addition, in the office and seminar areas, an internal glare shield reflects the remaining heat back outside.

Heating / Cooling / Ventilation

The building is connected to the district heating.
The library area is air conditioned. An additional heat recovery system stores the excess heat generated as a byproduct of the air conditioning in hot water storage tanks. All other areas are not air conditioned. In the lecture halls a ventilation system with heat recovery is used to ensure air exchange without sound pollution that window ventilation would cause.

Component Activation

To eventually meet the cooling demand of the summer months is the component activation of the concrete roofs in the seminar area is planned to meet the cooling demands of the summer months without any air conditioning. The component activation also serves to heat the seminar rooms during the colder months. As a result, heating input may be reduced.
