Group Marth is a leading player in the smart management of resources for housing estates and properties. For over 45 years, the group has combined expertise, innovation and a commitment to the environment to provide comprehensive and reliable solutions.

At the heart of the group, Brunata-Metrona specialises in the metering and sub-metering of energy and water consumption. Using smart meters, remote meter reading systems and digital solutions, the company ensures accurate meter readings and fair billing, whilst enabling residents to better understand their consumption and adopt responsible habits. Meters, heat cost allocators and smoke detectors complete the range, offering security and convenience to property managers.

In the same vein, e-trash, a pioneer in smart waste management since 2016, offers smart bins based on the ‘polluter pays’ principle. This solution encourages waste sorting, reduces costs and makes each user more accountable, whilst forming part of an eco-friendly approach certified by SuperDrecksKëscht (SDK). This saves time for property managers, who no longer need to calculate cost allocations thanks to e-trash’s tracking system, which quantifies each waste disposal by user. With Voltizy Charging, the group is tackling the complexities of electric vehicle charging in block-of-flats.

The subsidiary offers charging points for electric vehicles, complete with billing and a turnkey installation service. The principle is simple: only users pay. This means that residential complexes can provide a charging system for residents with electric cars without forcing others to contribute.

The Voltizy Community energy community goes one step further by enabling the sharing of green, locally sourced energy. This cooperative sets up, manages and re-bills energy flows, thereby enabling producers with surplus green energy to share it easily and more profitably with consumers keen to use responsible, locally sourced energy at a better price.

Voltizy Community also supports housing estates equipped with solar panels in becoming active participants in the energy transition by setting up collective self-consumption groups. Whilst reducing the administrative burden on property managers, it enables residents within a housing estate to benefit from the electricity generated directly on the roof.

By bringing these subsidiaries together, Group Marth creates a genuine ecosystem where simplicity and efficiency go hand in hand. Property managers and administrators benefit from streamlined, hassle-free management, whilst residents enjoy transparent and responsible tools that balance cost-effectiveness with environmental sustainability.

With its DNA rooted in innovation and environmental responsibility, its triple-A-rated building, its solar power generation, its supercharger and its electric fleet, the Marth Group in Kehlen is a veritable showcase for its innovative technologies.
