BOB Fischerhof in Hanover
The BOB was developed by BOB efficiency design AG as an architectural, modular office series product based on a holistic concept, with energy efficiency and long-term economic viability for tenants and investors at its core. In this ESG-compliant building, highly efficient technology is combined with office architecture tailored to the requirements of modern work environments. The design of the BOB is also individually adapted to each location and tenant. For example, at the Fischerhof in Hanover, the BOB references the established architecture of the surrounding neighborhoods and the brewery previously located on the site with its brick façade. For E.ON, the main tenant with around 600 workplaces at the BOB Hanover location, choosing a sustainable building as a company headquarters is a key consideration, as a highly efficient building also contributes to E.ON's sustainability and environmental strategy.

The Balanced Office Building BOB in Hanover, with its classic brick facade, recalls the industrial history of the site. An architecture was created that promotes exchange and communication: Rooftop terraces and courtyards provide the setting for relaxed interactions among employees. With a café and additional complementary services, BOB has also become a new hub in the Linden South district.

Modular Lighting Kit
The exciting task for KOBER LICHTPLANER was to develop a modular lighting concept for modern work environments that aligns with BOB's guiding principle and can be applied as a serial, modular lighting solution with individual configuration options to the different development and construction projects of BOB. BOB Hannover served as one of the first concrete applications of the modular lighting concept. The task was to ensure that the lighting could be quickly, economically, and sustainably adapted to the 80 architectural modules and the associated building services solutions, without having to plan the lighting anew from start to finish for each project. In addition to the requirements for modern, atmospheric, and perception-oriented lighting, all (quantitative) normative aspects of lighting (DIN 12464 / workplace regulations, connection capacities) were also planned modularly. In this process, specifications were developed for collision-free interaction between adjacent trades, and a concept for lighting control and light sensors was elaborated. Sustainability aspects, such as comparisons of the primary energy and CO2 footprint of the lighting, the use of recyclates in the luminaires, the reparability of the selected luminaires, and their recyclability at the end of their life cycle, were methodically analyzed and served as a basis for decision-making in the selection of the lighting system modular kit. The modular lighting kit is based on the following lighting systems:

Technical H-profile as a flexible infrastructure for accommodating luminaires, power rails, and other infrastructure (sensors, data cables)

Direct and indirect workplace-appropriate light inserts for the H-profile

Suspended luminaires for installation in the H-profile or on power rails

Spotlights & workplace-compliant track downlights mounted on power rails in the H-profile

Free standing floor luminaires for individual workplace lighting

In coordination with the future tenant, the modular lighting concept can already be coordinated as a 'phantom plan' during the lease process and calculated into the rent. The actual lighting design during the tenant fit-out planning then requires only minor adjustments to the specific conditions. The modular lighting concept provides cost transparency and enables quick and procedurally secure implementation in the interest of both the tenant and the landlord.
