Fa. Grenzebach, Bad Hersfeld

Grenzebach Office Building – Bad Hersfeld, Germany
Project overview

The Grenzebach office building in Bad Hersfeld serves as the headquarters for a company specialising in materials handling and processing technologies. Designed by Reith & Wehner with daylight façade planning by Köster Lichtplanung, the building emphasises openness and light. Although the project page provides limited details, the use of RetroSolar technology indicates a focus on environmental performance

Design challenge and RetroSolar strategy

Given the emphasis on daylight façade planning, the building likely employs RETROLux 50 mm blinds to control solar gains and improve light distribution. The reflective surfaces of the slats would send direct sunlight back out while allowing diffuse light to enter. The blinds would be integrated within the glazing units or mounted internally to protect them from the weather. This approach ensures that the façade retains a clean appearance while delivering high thermal performance.

Architectural outcome and significance

Although specific information is sparse, the Grenzebach office building demonstrates the ongoing collaboration between architects and daylight specialists in applying RetroSolar solutions. The project underlines that even industrial headquarters can benefit from advanced daylighting systems that enhance occupant comfort and reduce energy use.
