# Digital building logbook

A common repository for all relevant building data, including data related to energy performance such as energy performance certificates, renovation passports and smart readiness indicators, as well as data related to the life-cycle GWP, which facilitates informed decision making and information sharing.

## One place for a building's records

A digital building logbook is a repository, not a document. It holds all relevant data on a building, and the definition names four kinds: energy performance certificates, renovation passports, smart readiness indicators and life-cycle GWP data. Its purpose is to support decisions and information sharing among the construction sector, owners and occupants, financial institutions and public bodies. Financial institutions are named, which makes the logbook a possible source of building data for lending.

EPBD IV does not require Member States to create one. The operative articles refer to it with the qualifier "where available". Article 12(8) requires the renovation passport to be stored in, or accessible via, the digital building logbook where available. Article 16 on data exchange covers building systems' data and refers to the logbook in the same way. Article 22(7) requires the national energy performance database to be interoperable and integrated with other administrative databases on buildings, such as the national building cadastre or land registry and digital building logbooks.

So the definition describes something a Member State may build, and the Directive makes sure that if it exists, the other records connect to it.

Owners already have a related right under Article 16(1): building owners, tenants and managers can have direct access to their building systems' data, and on their consent it can be made available to a third party, without additional cost under Article 16(3).

> **What we could not establish**
>
> Staatsblad 2026, 103 does not mention a digital building logbook, and as at 14 October 2026 we found no Dutch logbook designated under EPBD IV. Where none exists, the "where available" duties in Articles 12 and 22 have nothing to attach to. This entry fixes the term. It does not decide whether the term catches your institution; counsel decides that.

## Questions and answers

### Must every building have a digital building logbook under EPBD IV?

No. The Directive defines it and refers to it "where available". It does not require Member States to set one up.

### Can a bank use the digital building logbook?

The definition names financial institutions among those it serves. Access depends on how a Member State organises the logbook and on data protection rules.

### Regulation

- [Energy Performance of Buildings Directive (EPBD IV)](https://gencompl.ai/regulations/epbd): EPBD IV is Directive (EU) 2024/1275, the recast Energy Performance of Buildings Directive. The Netherlands put its first tranche into force on 29 May 2026 (Stb. 2026, 103), with duties staged to 2033: recharging points in existing car parks from 1 January 2027, solar and lighting control from 1 January 2028. Energy label D by 2030 is still a proposal.
