Sustainability in real estate is no longer just a matter of good intentions. Investors, banks and large tenants want to see it in figures. You notice it in financing talks, in acquisitions and when lease contracts are renewed.
Which frameworks play a role?
- CSRD: a European directive for sustainability reporting by large companies. In 2025 Europe significantly reduced which companies must report. But companies that are not required to report often still receive questions from clients and lenders.
- EU Taxonomy: a European classification that determines when an investment counts as sustainable. For buildings, the energy label plays a major role.
- GRESB: a benchmark that real estate investors use to compare the sustainability of their portfolios.
Which data is requested?
The questions vary, but the basis is often the same:
- The energy label of the building.
- The actual energy consumption, preferably per year and per square metre.
- The split between gas, electricity and on-site generation.
- The resulting CO2 emissions.
- Sometimes also data on water, waste and indoor climate.
The problem: the data is often missing
In many buildings, actual consumption is only known from the annual bill. Nobody knows it per tenant or per installation. Data comes from different systems, or is typed in by hand. That takes time and leads to mistakes.
The solution: let the building supply the data
With smart meters and a central system, the data comes in automatically. Per floor, per tenant, per installation. Then reporting is a matter of producing an overview, instead of a search.
