New build or renovation projects require experienced and reliable partners. ewz guides real estate owners, site developers, cities and municipalities through the entire life cycle of the property and takes on responsibility for all energy-related matters in the background – from planning and implementation to efficient, safe operation.

Together with our customers, we develop and implement customised heating, cooling, electricity and mobility infrastructures from Romanshorn to Geneva.

Our sustainable energy solutions are suitable for real estate portfolios, building complexes, neighbourhoods, commercial/office buildings as well as special properties such as hospitals and stadiums.
