  41. 41. • 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. • 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. CONCLUSIONS
  42. 42. • A major difficulty in the development of the applications was the alignment between the users’ requirements and the available data sources. • It is difficult for users to envision innovative services that come from the integration of data from other domains. • It is important to simplify the applications: the information that the end-user receives is what he or she needs to take decisions. CONCLUSIONS
  43. 43. • 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. • Based on this understanding, it was possible to create our own mechanisms to interlink them in a unified information flow. CONCLUSIONS
  44. 44. • 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
  45. 45. • 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.
