Implementing KPIs for energy performance assessment in brownfield districts Anna Florea Sustainable Places 2014, Nice, France October 1, 2014 FP7/2007-2013 GA n° 600058 Introduction Districts Brownfield vs. greenfield Infrastructure Constraints Recommendation KPI • Need for change • Feasibility study • Citizen in the loop Target Data FP7/2007-2013 GA n° 600058 Value-chain Eibar, Spain Services: street lighting, district heating, electric power supply Actors: municipality, utilities, consultants, citizens District profile Daas Cloud Platform Kalundborg, Denmark Site and End User Selection Data Sources Selection / Creation Site Gateway Deploy Profiling Data Capture Deployment Framework Profiling Methodology (Ontology) Analysis Methodology (Use-Cases) Barcelona, Spain Hardware and Software DaaS Cloud Platform FP7/2007-2013 GA n° 600058 Analysis Retrofitting Decisions / Actions 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.)? FP7/2007-2013 GA n° 600058 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 Data Sources FP7/2007-2013 GA n° 600058 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. Formula Data Sources FP7/2007-2013 GA n° 600058 Computation Rule 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 Formula Data Sources FP7/2007-2013 GA n° 600058 Computation Rule Example: Eibar Pilot site FP7/2007-2013 GA n° 600058 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.
