of the building (EPC, BTI) and the economic cost
of the refurbishment

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.

• 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.

• 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.
