Precast concrete specialist Dennert is launching a standardized, preconfigured building system specifically tailored to social housing and municipal housing projects.
To significantly reduce construction times and economically deliver affordable housing without planning risks, the Franconian company relies on a consistent, solid, and hybrid modular construction method for multi-story residential buildings.
Planning Certainty in Wood and Concrete
The system is based on precisely prefabricated modules using a wood-concrete hybrid construction method for two-, three-, or four-module apartments (41 m², 64 m², or 87 m²). The residential units, with their standardized floor plans, are arranged around two central modules that house the stairwell, an optional elevator shaft, the utility shafts for building services, and the mechanical rooms. Consistent standardization has a positive impact on construction speed and cost-effectiveness. It enables highly efficient construction to create affordable living space. Standardized structural calculations prepared in advance significantly accelerate the approval process for buildings up to building class 3. A basement can be constructed using Dennert’s BASE prefabricated basement, which, like the entire system, follows the principle of industrial prefabrication and ensures seamless construction progress.
This construction method combines solid wood exterior walls with load-bearing concrete ceilings and floors. Alternatively, an all-concrete design is also possible. The ten-centimeter-thin interior walls are integrated ex-factory and feature precisely fitted door openings. All module types are available as ready-made BIM-compatible components (Revit).
Enhanced Sound Insulation Standard
Despite the screed-free construction, the modules meet the enhanced sound insulation standard according to DIN 4109-2015. This is made possible by a system-integrated ceiling suspension system that includes an 80 mm thick mineral wool insert. In terms of energy efficiency, the system meets the Efficiency House 40 and 55 standards. This makes the projects eligible for funding under current KfW programs. Since the system also meets the criteria for the Quality Seal for Sustainable Buildings (QNG), investors benefit from attractive special depreciation allowances under the Growth Opportunities Act. In particular, this allows for a combination of these special depreciation allowances and the KfW funding program “Climate-Friendly New Construction” in the low-price segment (KNN).
ETICS, Heat Pump, and Photovoltaics = Energy Efficiency
The exterior walls are factory-fitted with a 20 cm-thick External Thermal Insulation Composite System (ETICS). Energy-efficient heating is ensured by a central heat pump in combination with concrete core activation, supported by a photovoltaic system on the flat roof. Decentralized ventilation in each residential unit provides fresh air and a pleasant indoor climate. Hot water is supplied to each unit via a tankless water heater or storage tank. This elimination of large central systems ensures that the strict testing requirements of the Drinking Water Ordinance (regarding Legionella) no longer apply to the operator.
Process reliability through industrial prefabrication
Modular multi-story residential construction is the logical evolution of the proven ICON system for single-family homes. Like all Dennert solutions, the factory-finished modules are delivered to the construction site ready for installation. This not only minimizes noise and mess on-site but also allows for precise planning of construction schedules and costs. The next step in development has already been defined with the modular construction system for five-story residential buildings.
