1 . INTRODUCTION
1 .1 . SUMMARY
This deliverable aims at compiling all the necessary information with regards to the definition of Key Performance Indicators (KPIs) that are required by the Pitagoras project to assess the performance of the demonstration plant built within the project.
The KPIs assess the three pillars of sustainability commonly known: economic, environmental and social. To ensure well-tailored indicators, the technical dimension has been included in order to ensure complete and complementary views of the Pitagoras system.
All the KPIs are measurable and quantifiable aspects. To define them, there is the necessity to settle the minimum information required, set the limits of the system studied and define the calculation methodology is going to be used to be able to ensure that the maximum accuracy is reached.
This report contains information about the technical, environmental, economic and social KPIs defined for the developed Pitagoras concept demonstrated in the demo site of Brescia.
The deliverable D4.4. describes the work developed in Task 4.4. “Definition of Key Performance Indicators for the developed Pitagoras concept”. Here, the list of KPIs is defined, which will be calculated in Task 4.5. “Monitoring and performance evaluation of the demonstration plant” and reported in the related deliverable D4.5. “Monitoring and performance evaluation of the demonstration plant”.
1 .2 . PROJECT CONTEXT AND TASK PURPOSE
The work in this task has been performed in accordance to the work listed in the following tasks:
- Task 4.1. “Definition of monitoring concepts”. According to the prerequisites of the European Commission and as stated in Del D4.1., the monitoring should enable a comparison of the PITAGORAS project with other CONCERTO projects. This was already considered in the definition of the monitoring plan of the Brescia demo site, which was elaborated based on the EU document “CONCERTO Premium WP 1/3 “Indicator Guide”, Version 4. The evaluation should fulfil the same intention; the KPIs defined in this task follow the same approach.
- Task 4.2. “Implementation of monitoring devices and definition of specifications of the Pitagoras monitoring platform”. In this task the details of the monitoring data to be provided by the pilot plant were defined. The defined KPIs are based on the measuring points and data availability defined in this task.
- Task 4.3. “Development of the Pitagoras monitoring platform”. As the task title indicates, the objective here is to develop the Pitagoras monitoring platform in which the most important monitoring data of the pilot plant will be shown, including several calculated parameters about the performance of the individual components, as well as the overall plant. Specifically, one of the screens of this platform is dedicated to show the most important KPIs and how they evolve with the time. Both tasks have been developed in parallel; Task 4.4. has feed in Task 4.3. regarding the KPIs to be reported.
- Task 6.3. “Networking with other Smart City initiatives and key institutions”. One of the activities in progress in this task is the communication with SCIS in order to agree the KPIs that will be

reported to the SCIS and discuss available data and the procedure of data reporting. The on-going work in Task 4.4. has been discussed with SCIS to clarify doubts and ensure that we are following the correct approach for KPIs definition and monitoring and they are aligned with the most recent updates at SCIS.
In this report, particularly, the focus is on the definition of the final list of KPIs, their calculation methodology, their input data requirements and their relation to the case study. The defined KPIs are split into four main groups: technical, environmental, social and economic indicators.
As result from this report, the Pitagoras system´s performance will be assessed (in Task 4.5.) and shown in the monitoring platform (developed in Task 4.3.) through the KPIs defined following the established methodology.
1 .3 . CONTRIBUT ION OF PART NERS

2 . FRAMEWORK OF REFERENCE
The Pitagoras system contributes to the development of low energy and low carbon society reducing the fossil fuels consumption within an area and/or industry and favouring the deployment of energy efficient technologies and the use of waste energy. However, not only energy and environmental aspect should be taken into account, but also social, technical and economic targets and boundaries must be considered when the performance of the Pitagoras system is evaluated.
In this sense, Europe is working in the development and validation of indicators within international standards and committees, research and innovation projects, European initiatives, decision-making tools, strategic plans, etc. This section describes the framework of reference on which the work developed in this task has been built on, ensuring the alignment of the KPIs of the Pitagoras project with the most recent and relevant on-going activities and initiatives on the topic.
a. International standard:
“ISO 37120:2014 Sustainable development of communities – Indicators for city services and quality
of life” became the first international standard for cities to be published. Its main objective was to
establish a set of indicators to evaluate and monitor city performance in terms of sustainable
development and resilience.
b. Technical committee:
“ISO TC 268/WG2. Sustainable Development in Communities — Inventory and review of existing
frameworks on sustainable development and resilience in cities”, complements the list of indicators
from ISO 37120.
c. European projects and initiatives:
CONCERTO Premium. This initiative has built up a solid database where a great amount of projects and indicators are to be found, which have served as a basis for the ones defined in PITAGORAS. The EU document CONCERTO Premium WP 1/3 “Indicator Guide”, Version 4 [1] has been used as reference.
Smart City Information System (SCIS). Supported by the European Commission, the SCIS is a continuation of the CONCERTO series of projects, started back in 2005. In particular the two reports “Technical monitoring guide” [2] and “KPI guide” [3] published on 15th July 2016 are to be mentioned.
CITYKEYS Project. The aim of CITYkeys is to develop and validate, with the aid of cities, KPIs and data collection procedures for the common and transparent monitoring as well as the comparability of smart city solutions across European cities. This initiative has served as basis for the development of the indicator forms [4]
CITyfiED project (“Replicable and Innovative Future Efficient Districts and Cities”, H2020 programme). Within “D2.25: Methodology for city renovation at district level. Systemic approach” [5] CITyFiED has defined KPIs for district renovation based on the European framework.

Page 5/38
REPLICATE project (“Renaissance of PLaces with Innovative Citizenship And Technology”, H2020 programme). Within “WP10: Monitoring” KPIs of different Smart City solutions have been defined at city and district level. The defined indicators have been reported on D10.1 “Report on indicators for monitoring at project level” and D10.2 “Report on indicators for monitoring at city level” [6]
“The Covenant of Mayors in Figures and Performance Indicators: 6-year Assessment” [7]. The European Commission’s Joint Research Centre just published a 6-year assessment report on the Covenant of Mayors. Based on the data collected from Sustainable Energy Action Plans (SEAPs), the report provides main statistics of the data set in terms of greenhouses emissions and estimated reductions, final energy consumptions and estimated energy savings and clean energy production in the local authorities.

3 . BRIEF DESCRIPTION OF PITAGORAS SYSTEM
The following figure represents the main idea and technologies behind the Pitagoras system concept demonstrated in Brescia demo site. The defined KPIs, reported in this deliverable, are applied to this system.
Melting steel scrap in an electric arc furnace (EAF) is an energy intensive process. The Pitagoras pilot plant has been implemented in the EAF of ORI MARTIN steel mill, in which the energy in the generated flue gas was not utilized but cooled in a quenching tower before this intervention. The Pitagoras plant has allowed to revalorize the waste energy contained in the fumes.
In the new plant, the waste heat of the flue gas produced by the EAF-process is used in the waste heat recovery unit (WHRU) to form steam which then, during the summer period, feeds a water cooled Organic Rankine Cycle (ORC) turbogenerator or heat exchangers for district heating (DH) supply to the city DH network during the winter period. The plant operates, therefore, in a seasonal mode; it produces electricity in summer time (for self-consumption of the steel mill) and district heat in winter time; each of them being characterized by the same duration of six months during the year.
More detailed information regarding the developed pilot plant is provided in the Pitagoras project deliverable D2.16. “Publishable report on the two demonstration plants” available in the project website (http://pitagorasproject.eu/) [8].

It should be clarified that when the KPI refers to an indicator defined by CONCERTO initiative, the CONCERTO numbering as reported in [ref] is mentioned in the “Indicator name”, in order to ease the evaluation between different CONCERTO and Smart City projects. Additionally, a second definition of the indicator, more specific to the solution developed within the PITAGORAS Project, is added when necessary so that the meaning of the indicator applied to the specific technology developed in the project can be clearly understood.
The fact that the PITAGORAS demo plant operates in two operation modes during the year (winter mode (from mid-October to mid-April): thermal energy production and summer mode (from mid-April to mid-October): electricity production) should be kept in mind. It has been necessary to define two separate indicators to refer to each of the operation modes.
The following table summarizes the complete list of KPIs defined in the Pitagoras project. Characterization of each indicator, providing the relevant information for each KPI, is provided in the following subsections 5.1., 5.2. and 5.3.

baseline is defined as the interet rate that results into a net present value of zero
The IRR is the interest rate, also called the discount rate, that is requiered to bring the net
present value to zero. That is the interest rate that would result in the present value of the
capital investment, or cash outflow, being equal to the value of the total returns over time, or
cash inflow

to be recovered from the cash inflows generated by the investment
years
The dynamic payback period of an investment causing energy savings or energy production in
comparison to a baseline is defined as the smallest planning horizon that causes a non-
negative net present value

5 . CONCLUSIONS
This report provides the technical, environmental, economic and social KPIs that have been defined for the Pitagoras concept based on industrial waste heat revalorisation demonstrated in the Brescia demo site.
The pilot plant is under an extensive monitoring campaign at the moment. One year operation data will be available by October 2017. The next step as continuation of the work performed in this task is the calculation and reporting of the defined indicators. The ones that are “static” (to be calculated once) will be assessed with one year operation data. There are others that are “dynamic”; these are being calculated on weekly basis internally by the partners involved on the detailed performance assessment and they will be reported on monthly basis on the Pitagoras monitoring platform and in deliverable D4.5. “Monitoring and performance evaluation of the demonstration plant”, which will provide to the users an overview of the pilot plant performance evolution over the year.
