A full first step towards
sustainability certification

The Sustainable Housing Assessment is primarily developed as an ESG assessment tool for bond aggregators, enabling housing providers, in their initial stages, to demonstrate their ESG credentials to internal and external stakeholders.

Furthermore, the Sustainable Housing Assessment can serve as a first step in gearing up to the Certified Sustainable Housing Label at a later stage, supporting housing providers that raise capital via bank loans, private placements or bond issuances.

Certification Process

The assessment process is a joint effort between the housing provider and RITTERWALD. The process can be seperated in 6 clear steps and requires approximately 4 to 6 weeks.


The Assessment entails various criteria to measure ESG credentials. The Assessment is customised to the national regulatory environment and applied metrics in national/regional markets. An annual review is undertaken to ensure the housing provider has complied with the implementation and fulfilment of the goals set out at the time the Assessment was awarded.
