The real estate industry is facing a fundamental change. What was long considered a voluntary additional service is now a central criterion for value retention, letability and financing of properties: sustainability – summarised under the term ESG.
As an owner-managed company with over 30 years of experience in the Ruhr region, we experience this change daily in practice. And we are convinced: those who act now secure the value of their property. Those who wait risk it.
What Does ESG Mean for Real Estate?
ESG stands for Environmental, Social and Governance – three dimensions that together describe how responsibly a property and the people in it are managed.
E – Environmental
How much energy does the building consume? What CO₂ footprint does it leave? Are energy-efficient modernisations planned or implemented?
S – Social
How are tenants treated? Is the building accessible? Does the property contribute to a stable social structure in the neighbourhood?
G – Governance
How transparent is the management? Are decisions documented in a comprehensible way? Are there clear processes for conflicts of interest?
These three dimensions are not abstract concepts from the sustainability report of a large corporation. They are concrete criteria that already decide today whether a property remains financeable, lettable and saleable.
Why ESG Is Relevant for Every Owner
The Risk of "Stranded Assets"
Over 70 percent of buildings in Germany are more than 30 years old. Many no longer meet current requirements for energy efficiency and climate protection. Experts refer to such properties as "stranded assets" – properties that lose significant value due to tightened legal requirements and changed market demands.
The loss of value does not begin on the day a new regulation comes into force. It sets in much earlier: when tenants prefer more energy-efficient alternatives, when banks become more critical in financing, or when institutional buyers exclude a property from purchase for ESG reasons.
As managers and advisors, we see it as our core task to alert owners to this risk at an early stage – and to develop strategies together to minimise it.
The CO₂ Cost Allocation Act: ESG Is Already Mandatory
Since 1 January 2023, the CO₂ Cost Allocation Act (CO2KostAufG) has been in force. It obliges landlords to allocate CO₂ costs from fossil heating fuels between themselves and tenants according to a 10-stage model – depending on the energy standard of the building.
In practice, this means: the worse the energy class of a building, the greater the landlord financial share of CO₂ costs. Managers who do not correctly reflect this allocation in the service charge settlement risk tenants reducing their heating cost bill by three percent.
For us at Wellhöner Immobilienmanagement, the legally compliant implementation of the CO2KostAufG is a self-evident component of every rent and service charge settlement.
Institutional Requirements Are Rising
Anyone who manages properties for banks, insurance companies, funds or family offices knows the development: ESG reporting has long ceased to be a nice extra but is a prerequisite for cooperation. Investors and financiers demand robust key figures on energy consumption, CO₂ emissions and governance standards – and increasingly also for portfolios of smaller and medium-sized properties.
As a company that has served both private and institutional clients from the outset, we are familiar with these requirements and can support our clients with ESG-compliant documentation and reporting.
ESG in Management Practice: What We Specifically Do
Energy Assessment and Advice
The first step towards an ESG-compliant property is clarity: what energy standard does the building have? Which measures are sensible, economical and eligible for funding? We analyse the current energy status together with our clients and develop realistic roadmaps for modernisations – without unrealistic promises, but with a clear eye for what is feasible.
Legally Compliant CO₂ Cost Settlement
Every service charge settlement we prepare takes into account the applicable 10-stage model of the CO2KostAufG. Owners do not have to work through legal texts themselves – we ensure that everything is billed correctly, transparently and comprehensibly.
Social Responsibility as a Management Standard
Sustainability does not end with the energy performance certificate. In our daily management work, ESG also means: respectful interaction with tenants, fast response times to concerns, fair communication and the active effort towards stable, socially balanced tenant structures. Satisfied tenants are not a matter of course – they are the result of consistent, human management work.
Transparent Governance as a Fundamental Principle
Our clients receive complete insight into accounting, service provider selection, maintenance measures and contract status at any time. We document decisions in a comprehensible manner and always act exclusively in the owners interest. This is not an ESG measure for us – it is our fundamental understanding of good management.
ESG as a Competitive Advantage – Not Just an Obligation
It would be short-sighted to view ESG only as a regulatory burden. Properties that meet ESG criteria demonstrably achieve higher rents, find tenants more quickly and retain their value better in the long term. Banks offer more favourable financing conditions for ESG-compliant properties. And buyers – whether private or institutional – are prepared to pay a premium for sustainable stock.
ESG is therefore not a cost factor but an investment in the long-term value of your property.
Our Conclusion: Those Who Act Now Will Be Ahead Tomorrow
Requirements for properties are rising – this is no longer a forecast but reality. CO₂ requirements are being tightened, reporting obligations expanded, tenants and investors more demanding. At the same time, modernisation measures today offer attractive funding opportunities that may not exist in this form permanently.
At Wellhöner Immobilienmanagement, we stand for management that does not just focus on today but on the long-term development of your property. ESG is not a buzzword for us – it is the consistent continuation of the values we have worked by for more than 30 years: reliability, integrity, transparency and competence.
If you would like to know how well your property is positioned for the ESG requirements of the future – talk to us. We analyse, advise and accompany you on the path to a sustainable and value-stable property.
