Sustainability & ESG
Responsibility for your property – today and tomorrow
Real estate is a long-term asset. Anyone who wants to preserve it permanently cannot avoid one topic: sustainability. What investors and legislators have been demanding for years has long been lived practice for us at Wellhöner Immobilien – because it corresponds to our fundamental understanding of responsible management.
ESG stands for Environmental, Social and Governance – i.e. ecological responsibility, social action and transparent corporate governance. Three pillars that we do not see as a box-ticking exercise, but as a natural extension of our values: reliability, integrity and transparency.

What this means for your property
Energy Future-Proofing
Buildings with poor energy performance are at risk of losing value – experts speak of "Stranded Assets". We identify this risk early, advise you on sensible modernisation measures and ensure correct CO₂ cost allocation according to the applicable CO2KostAufG – legally secure and transparent for all parties involved.
Social Responsibility in the Portfolio
For us, tenants are not mere cost items. Only those who treat the people in the managed properties fairly and reliably secure long-term stable tenancies and the good reputation of your property. This has always been our aspiration – ESG gives it a name today.
Transparent Corporate Governance
Whether service charge accounting, service provider selection or maintenance planning – we lay everything open. Our clients know at all times what is happening with their property and why. For institutional owners, we also provide the necessary ESG-relevant metrics and evidence.
