Landgrafenplatz

Into the future with sustainable technical building services

A building project in the change of time.

DES TGA Design is responsible for the technical building services for a remarkable project on Landgrafenplatz in the Hessian town of Friedrichsdorf. A therapy centre, the Salus Klinik, has stood there since the 1970s. The building is now being refurbished to high energy, ecological and economic standards and transformed into flats. With a total of about 7,500 m2 of usable space and about 100 high-quality residential units, the two high-rise buildings are thus among the largest residential buildings in the city. The façade, which is structured by complex geometric recesses, is particularly sophisticated and aesthetically interesting. Extensive greening is planned in the façade and also on the roof of the building as part of the refurbishment.

Technical building services for optimised energy and ecological functionality.

In the context of the global energy turnaround, renovations of existing buildings are a central component of the necessary measures, as in the case of Landgrafenplatz. DES TGA Design sets an exclamation mark in the field of technical building equipment with the forward-looking solutions used for Landgrafenplatz. The conversion of the building is to achieve the energy standard BEG 55 EE. The heat is to be provided primarily via a central air heat pump. The heat will then be distributed to the individual building units via a separate local heating network. Also innovative: to further increase energy efficiency, the solutions provide for exhaust air heat recovery from the ventilation system.

Harnessing the power of the sun: Photovoltaics.

For optimal mobility, Landgrafenplatz is getting a multi-storey car park, on whose roof electricity is produced with the help of photovoltaic systems. The energy generated is used both in the residential units and by the heat pump. This creates an ecologically and economically profitable energy cycle. Surplus electricity can also be fed into the local power grid as needed, or is available for charging parked electric cars. In this project, we successfully cooperated with the architectural office Willen Associates Architekten and the engineering office KREBS+KIEFER Service GmbH and were commissioned for the service phases 1-4.

*BEG 55 EE: The primary energy requirement of the building is max. 55 % of the requirement of a statutory reference building. In addition, 55% of the heating and cooling requirements are covered by renewable energies.
