Innovative Handling EPC Data

Building Logbook

Logbooks are dynamic repositories storing relevant building data beyond the EPC which enable better and more effective use of the data. They are a promising tool to overcoming current data gaps and data barriers among market participants. Logbooks have been developed in several jurisdictions but with diverse objectives and with varying links to the existing EPC framework. The availability of consistent and reliable data can contribute to the creation of innovative services and business models, reduced transaction costs and administrative burdens for the building owner, more effective policymaking, as well as supporting the construction value chain.

X-tendo identifies how EPC registers and systems at different stages of development can support the development of logbooks. It also explores how logbooks can support other innovative features, such as one-stop-shops and tailored recommendations. For the test projects, X-tendo trials three different logbook approaches with the objective to link the EPC data to other datasets and solutions:

  • logbook as a data aggregator (Greece) through a webservice which is the backend to the logbook data exchange between the EPC registry, tax department and renovation financing programme
  • logbook integrated in the existing one-stop-shop portal (Portugal) to provide new functionalities and services to building owners and market participants
  • a dashboard (Estonia) bringing together the EPC data, real energy consumption data and an online application that support building owners to find information on potential renovation measures and energy savings.

Introduction
  • Introductory report

    Brief report giving an overall evaluation of the feature and describing the basic concept, the methods behind, existing good practices and how to implement it.

Methodological approaches
Calculation procedures
  • Concrete implementation of new energy performance certificates features: testing and results in nine countries

    This report provides the summary of the outcomes of the testing activities for each of the 10 features in one or several implementing countries. This is mainly based on the analysis of the evaluation questionnaires filled out by the implementing partners, but also on the content of the testing results reports. The questionnaires hereby consist of general questions along the testing steps, questions on testing time and related costs, an evaluation against defined cross-cutting criteria (Quality and Reliability, User-friendliness, Economic feasibility, and Consistency with ISO/CEN standards) and final thoughts.

  • Tools and IT-components of the proposed calculation and data handling procedures tested in x-tendo

    This report describes the tools and IT-components of the proposed calculation and data handling procedures for the feature building logbook. It provides the technical specifications for linking the national logbook with the EPC data.

Recommendations for Implementation
  • Implementation guideline and replicability potential of the innovative feature for the next generation EPCs

    This report brings together the outputs of the evaluation of the test projects alongside the insight from end-users and stakeholders. It includes estimations of (1) the barriers and drivers for the wide uptake of the feature, (2) the effects of the wider implementation of the developed innovative feature of EPCs in Europe and (3) the necessary next steps in order to implement the innovative feature in the certification schemes around Europe.
