Study of data sources

Data categories 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?

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.)?

What kind of information can be captured?

What are the data sources?

What are the communication patterns?

KPI definition

Energy performance

Relationship between energy consumption and the needs covered.

Feasibility of energy savings

Relationship between the cost of the change in a current energy scenario and the profit obtained with this change

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

Formula Data Sources Computation Rule

• 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.
