Renovation Services
Energy-Efficient Renovation
We reduce your energy consumption and improve living comfort through targeted energy modernization measures for your building.
Insulation of Facade, Roof and Basement Ceiling
Professional thermal insulation of the building envelope reduces heat loss, lowers heating costs and improves indoor climate.
Modernization or Replacement of the Heating System (e.g. Heat Pump or Hybrid Heating)
Replacement of outdated heating systems with modern, climate-friendly alternatives – heat pumps, hybrid heating or renewable energy connections.
Heating Technology Optimization including Hydraulic Balancing
Increasing the efficiency of existing heating systems through hydraulic balancing, modern pumps and smart controls. Less energy at the same comfort level.
Frequently asked questions
Which measures does WAV handle in an energy-efficient renovation?
WAV coordinates energy-efficient renovations holistically: building envelope, insulation, windows, roof, heating technology, ventilation, photovoltaics, storage systems and technical building integration. Through the structure of the WAV GROUP and a network of qualified partners, many services can be bundled and coordinated for each project.
Why is central coordination important in energy-efficient renovation?
Energy-efficient renovations almost always involve several trades at the same time. If insulation, windows, heating, electrical systems, PV and ventilation are not coordinated properly, interfaces, delays and technical conflicts can arise. WAV coordinates these areas so that planning and implementation run in one structured process.
Does WAV support funding, KfW and BAFA topics?
WAV supports the basic review of funding options and the technical preparation of relevant project documents. This can include energy-related measures, KfW/BAFA topics and coordination with specialist planners. Specific eligibility always depends on the property, planned measures and current programme conditions.
Can WAV plan heat pumps, photovoltaics and storage together?
Yes. Heat pumps, photovoltaics and storage should not be considered separately, but as one connected energy system. WAV can coordinate these areas within the WAV GROUP and with qualified partners so that energy generation, consumption and building technology work together sensibly.
Which buildings are suitable for an energy-efficient renovation by WAV?
WAV supports energy-efficient renovations for single-family homes, multi-family houses, existing buildings, residential complexes and commercial properties. A structured assessment is especially useful when several measures are to be combined or when a property is to be upgraded technically and economically for the long term.
In which regions does WAV offer energy-efficient renovations?
WAV supports projects around Baden-Baden, Rastatt, Bühl, Achern, Karlsruhe, Offenburg, Pforzheim, Mannheim, Heidelberg, Freiburg and in the Rhine-Main area around Frankfurt am Main. Depending on the project scope, further locations in Baden-Württemberg, Hesse and neighbouring regions are also possible.
