  1. 1. ENERPAT/ENERHAT: integrating energy certificates with other data sources to foster building retrofitting Leandro Madrazo ARC Engineering and Architecture La Salle Barcelona, SPAIN
  2. 2. The aim of the ENERSI research project is to develop a platform that enables the creation of data-driven energy assessment services based on the integration and subsequent analysis of the integrated energy-related data. ENERSI: Energy Services Platform based on the integration and analysis of data from multiple sources (2014-2017) The services supported by the platform will help stakeholders to take well-informed decisions in their respective decision-making realms to improve buildings’ energy efficiency.
  3. 3. ENERHAT For building owners. To know the current status of the building (EPC, BTI) and the economic cost of the refurbishment ENERPAT For city planners. To evaluate the current status of the building of a municipality, and to apply large- scale renovation programmes in an urban area.
  4. 4. ENERHAT Renew your property To provide building owners the information which can help them to take decisions concerning the refurbishment of a single building or dwelling. www.enersi.es/enerhat >600.000 Energy Performance Certificates >25.000 Building Technical Inspection >600.000 Parcels National Cadastre

  17. 17. Visualizing energy performance certificates in the whole territory, at municipality scale (parcels) Aggregated data at municipality scale and the previous scale (number of certificates, energy consumption, and emissions)
  18. 18. Percentage of dwellings to be refurbished Segmentation of the Building stock in the municipality Assessing the impact of refurbishing a percentage of the building stock for each group of buildings
  19. 19. Assessing the impact of refurbishing a percentage of the building stock for each group of buildings
  20. 20. Calculating the costs and energy savings for all the buildings selected, grouped in different clusters (per construction year, …)
  21. 21. Visualizing the buildings to be renewed, according to the clusters selected before
  22. 22. Identifying a particular building amenable to renovation; link to ENERHAT to calculate the renovations costs and energy savings
  23. 23. List of buildings amenable to renovation
  24. 24. A downloable report is generated

  35. 35. • ENERHAT and ENERPAT integrate building data, an on- line building refurbishment assessment tool, and refurbishment policies to make it easier for building owners and city planners to take informed decisions to improve buildings’ energy performance. • In order to integrate heterogeneous components - such as data from various sources, refurbishment guidelines and policies and on-line assessment tools- in a seamless process within the on-line applications we have created, it was necessary to gain a deep understanding of their contents and structure. CONCLUSIONS
  36. 36. • There is no standardized process to integrate data from multiple domains and sources and to derive new services from them. Each case is a particular one. • Even though the underlying complexities of this integration are hidden to the end-users, the procedures to interconnect the various components need to be transparent to experts and professionals, who should be able to trace the data transformation processes which are carried out within the applications. CONCLUSIONS
  37. 37. • In the process of integrating the data from the various sources, some inconsistencies and errors in and between these sources emerged. • Although some of these problems were solved within ENERSI, long-term solutions should be taken at the data sources level: using standardized procedures to name addresses, classifying building components and systems, or assessing building performance using standards. • Therefore, one of the consequences of the data integration was to make recommendations to improve the data collection and management.
