In the first one, several stakeholders such as the technical
experts of the municipality, or the utilities can contribute
providing the data that is needed for the initial analysis.
However, the municipality plays the key role in the definition
of the objectives of the city. energy technologies or the socio-economic characterization of
the area. Besides, the ECG needs to take into account the
opinion of the citizens in order to foresee and prevent
potential implementation barriers for each of the tentative
technologies and measures.
Several steps can be distinguished in Phase I. The first one is
the pre-diagnosis and the data collection in which the city is
evaluated with the aim of understanding the current city
context. Due to the complexity of the city energy planning,
the methodology considers a multi-criteria and holistic
perspective from the very beginning. This complexity is shown
in the wide variety of city strategic areas (aspects that will be
treated by the implementation of specific improvement
measure at district and city scale) and application areas
(sectors of the city in which the different interventions can be
implemented) that compose the analysis matrix of the
methodology. Taking into account all the information gathered at district
scale, the energy demand and consumption of the base case
scenario are modelled for the district in order to compare
suitable scenarios in the next phases. This is a complex analysis
in which various methods and tools need to be combined by
the ECG to obtain an appropriate characterization.
The output of this analysis will serve to define the specific
objectives of the city as well as the specific targets for the
improvement of the environmental, economic and social
situation of the district.
3.3.3 P HASE III: D EFINITION AND ANALYSIS OF THE INTERVENTION AND
The second step is focused on the calculation of specific City
Level Indicators (Level 1) that, through the comparison of their
values respect to other cities, allow getting a better
understanding about the city´s strengths and weaknesses.
Level 1 indicators are composed by 17 mobility related
indicators, 14 building related indicators and 14 energy
related indicators that were the focus of a double validation
process. The first one corresponds to internal validation by the
cities involved in the CITyFiED project and the second one
corresponds to the external validation by the City Cluster and
the Community of Interest. The results of this analysis combined
with other techniques such as the SWOT analysis or the
Workshops, which include the main stakeholders of the city,
help to define the general objectives and the long-term city
vision.
SCENARIOS
While the inputs from this phase are the objectives from the
city understanding and district diagnosis, the output is the
definition of the retrofitting scenarios that could be
implemented in the district in alignment with these premises.
Phase III is a two-steps approach in which the energy
measures are analyzed separately and those selected are
combined in the scenarios.
In this phase, the ECG is in charge of the activities. Thanks to
its multidisciplinary background, it carries out the feasibility
analysis of measures and the scenarios generation supported
by the proposed tools. It should be established a fluent
dialogue with the Technical committee.
On the other hand, this is the only phase of the methodology in
which ‘Citizens’ and other stakeholders participation’ inclusion
is minor. The reason is that this phase entails only technical
aspects and the decision-making of the individual measures is
an intermediate step in the process before achieving the
scenarios evaluation and prioritization that will be carried out
in Phase IV.
3.3.2 P HASE II: D IAGNOSIS OF THE CITY AT DISTRICT LEVEL
Based on the results of the Phase I and on a new analysis of
the city through the evaluation of its districts, the main
objective of the Phase II is to define the specific objectives at
district scale. This will help to defined in the Phase III the set of
measures that will be part of the alternative scenarios.
Energy Conservation Measures (ECMs) are defined as
‘measures that are applied to a building or group of buildings
to improve energy efficiency and are life cycle cost effective
and also they involve energy conservation (...)” [11]. The ECMs
identified as most cost-effective are shown in a catalogue
within the methodology.
The main stakeholders involved in this phase are the
Municipality, the ECG and the citizens. Their responsibility and
implication is described for each sub-phase.
The first step of this phase aims to define the main focus of the
analysis. Here, the role of the Municipality for the selection of
the districts that will be renovated in the following years is
critical.
The initial step of the phase consists of applying a first filter
on the ECMs according to the objectives to achieve defined in
phases I and II, to discard some of them. To guide this process,
the grade of relationship between measures and some
sustainable objectives are shown within the methodology.
The Municipality will have to interact with the ECG in order to
understand properly the potential of each district in
contributing to the transformation of the entire city. The
diagnosis of the selected districts includes among other aspects
the evaluation of the potential for integrating renewable
Secondly, the preselected ECMs are studied in detail to
achieve a final selection, especially considering their energy
