Study of data sources
Data categories
What kind of information can
be captured?
Description
Geographical
Topography of the site, climate, etc.
Intensity level
Demographic data (i.e. population density).
Wealth level
Household disposable income, surveys on comfort.
Activity level
It is a coding system of land-use planning used by local governments.
Energy studies
Technical data of buildings, street light systems, etc.
Energy
Energy consumption, CO2 emissions, etc.
Energy cost
Investment cost, energy consumption costs, etc.

How secure and reliable should be the connection from the pilot site to
the platform?
What are the data sources?
What are the communication
patterns?

How intensive is the communication between the pilot site and the
platform (Data rate and message rate)?

Which are the data sources visible for the platform and vice versa?

Considerations for third party data sources, if any.

Protocols supported by the data sources?

Availability of the data source in terms of legal access to it?

Source of the data (a specific web-site, institution etc.)?

KPI definition
Energy performance
Feasibility of energy savings
Relationship between energy
consumption and the needs covered.
Formula
Relationship between the cost of the
change in a current energy scenario and the
profit obtained with this change

Computation
Rule
Data Acquisition
• Scope of every data source.
• Pilot site
• Cloud
• Entry point to the platform
• Aggregation interface
• Profiling Module
• Horizontal Services
• gateways are hubs of pilot sites data sources.
• Pilot sites always start the communication to the
DCP.

KPI Computation
• Rules and calculations
• EPL syntax
• Computation triggered by incoming messages
• Engages profile data
• Data storage
• Instantiation Data
• Energy Profiles
• Sensed Data
• Key Performance Indicators

Conclusions
• The solution focuses on the brownfield districts and is driven by
requirements consolidated from use-cases of different type and
scale and having different retrofitting targets.
• Multi-tenancy is an important feature of the solution allowing
managing multiple locations within one instance of the platform.
• District performance, retrofitting campaign feasibility and citizen’s
comfort considered as main drivers for KPI selection.
• A common KPI computation approach is defined, fitting different
kinds of indicators, found throughout the requirements analysis.
