In 2018, the Energy Performance of Buildings Directive (EPBD) introduced Building Renovation Passports (BRP) to enable buildings to scale energy performance through a Scheduled Renovations Roadmap (SRR). The Digital Building Logbook (DBL) was introduced in 2021 as a repository of relevant building data to facilitate informed decision-making and information sharing among stakeholders. In Spain, both tools (DBL + SRR) have been studied separately in an incipient way. However, the interconnection of data in the tools come from the same document base. Evidence suggests that when building information is used in isolation, its value is diluted without stakeholder awareness. In this paper, we move towards unifying both tools (DBL+SRR) in a single comprehensive tool called the Libro del Edificio Electrónico (LdE-e), with the aim of producing a single building database to drive multi-building renovations. For this purpose, the data fields of existing building information, assessment and management tools in Spain were studied in detail and reinterpreted in a new interconnected data structure. To evaluate the formulation of the LdE-e proposal, 11 semi-structured interviews were held with a panel of 13 experts specialized in real estate, building and energy efficiency. After these sessions, the LdE-e was reformulated, and the model was strengthened by analyzing vectors such as governance, management, usability, data flows, stakeholders and the impact of including new technologies such as BIM and blockchain. The results suggest that the LdE-e would improve control of the operation and maintenance of (new or existing) buildings, the programming of renovation actions based on deficits identified in technical inspections, and other aspects.

La Directiva (UE) 2018/844 (Energy Performance of Building Directive-EPBD) introdujo los Pasaportes de Renovación de Edificios (Building Renovation Passport-BRP) como instrumentos que prometen impulsar la renovación energética a largo plazo en la Unión Europea. En España, empero, la transposición total de esta Directiva no se ha realizado y el estudio de las particularidades del BRP español es expectante. Este artículo pretende aportar elementos que contribuyan al debate de la implementación del BRP español mediante el estudio de iniciativas existentes de BRP europeos, determinando sus carencias y oportunidades, y destacando las diferencias para la futura aplicación del instrumento en España. El análisis sugiere que la implementación del BRP español sería útil solo en condiciones de simetría informativa y con población sensibilizada, siendo imprescindible reforzar la transparencia de los datos y la generación de confianza en la información energética existente. Mención aparte merecen las dificultades derivadas del régimen de multipropiedad residencial dominante.
