6. 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.
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.

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. • 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. • 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. • 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. • 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.
