includes different aspects as Risk management, Supervision
and Quality Control plans. Also the BIM approach and BIM
Execution Plan are considered during this phase.
At least, procedures for the energy performance and energy
savings, economic analysis, social acceptance, and life cycle
analysis should be defined. For instance, in order to evaluate
the energy performance of the intervention CITyFiED
Methodology recommend the use of IPMVP and ASHRAE
protocols, which are focused on ECMs.
All the stakeholders from the different groups, including
citizens and end users, participate in this stage. Particularly, is
remarkable the role of Contracting Parties that form part of
the Consultant experts and that have not previously been
involved in the process. They are usually selected by a
tender/bidding process and their scope of works, supply, etc.
is defined by the tender documents.
However, sustainability is not only energy and environment,
but other issues play an important role, as Social acceptance,
Economic issues, Quality control of the interventions, LCA, which
all are included within the proposed plan.
The Technical Definition of measures is developed within the
BIM framework and related to the selected project delivery
method and procurement process, considering that most part
of the Municipalities need to face it to accomplish legal
requirements. Chronologically, the order of these actions
depends on the scope of services that the Municipality would
want to cover during the process according to its technical
capacity.
The Technical Committee is the main responsible actor during
Phase VII, deploying both the commissioning tasks and the
Sustainable Evaluation Plan previously defined. Specifically
the monitoring programme implementation is responsibility of
the Monitoring committee in case of any, in order to gather the
real data consumption from the metering systems.
The final impact that the renovation has on the sustainability is
evaluated not only at district but also at city scale. On the one
hand, level 3 indicators, which were proposed for impact
evaluation target, are calculated again, but this time with real
data from monitoring mainly, and the analysis carried out of
the overall performance. On the other hand, the impact after
renovation at city level is calculated in order to verify the
accomplishment of the general and specific objectives defined
during Phase I and II, through recalculating Level 1: City
indicators and their results compared.
With respect to the Project Delivery Method for the
contracting formats, it is recommended the application of the
IPD to the maximum extent that the public procurement
requirements allows. It is ‘a collaborative alliance (…) to
optimize project results, increase value to the owner, reduce
waste, and maximize efficiency through all phases of design,
fabrication, and construction” [10]. It emphasizes BIM
potential, the early involvement of stakeholders and it has a
risk and benefits sharing approach. As recommendation for
the Method of Procurement aligned with IPD, it could be
followed the sustainable procurement in which the tender
documents are performance based and not prescriptive
document and the design is not detailed in tender documents
[14].
Finally, correction actions are deduced from the short to the
long term and from all the strategies for future renovation
actions.
4. C ONCLUSIONS
The financial resources have to be clarified in this phase. It is
recommended for some measures to follow the Energy Service
Company (ESCO) business model, especially in the case of
private ownership of buildings.
The need of innovative methods and the collaboration of
municipalities with external consultancy groups to guide them
in their application is perfectly face in CITyFiED Methodology.
As a holistic procedure for the city renovation at district level,
it guides the municipalities under a multi-criteria perspective
along the urban renovation process. The integration of
supporting tools (3 level of indicators, SEP, Replication model,
etc.) supports the decision-making process from the diagnosis,
selection as well as final evaluation of measures and
retrofitting scenarios, as a useful management and control
tool.
Within this phase it is defined the Sustainable Evaluation Plan
(SEP) to be applied during phase VII for the monitoring and
the evaluation of the measures.
3 .3.7 P HASE VII: M ONITORING AND IMPACT ASSESSMENT EVALUATION
During this phase the strategy and their actions are completed
attending to their priority and they are commissioned when
finish. For that purpose, a Commissioning Plan should be follow
in order to test the correct performance of the ECMs
installation and guarantee the operability of the system in
terms of performance, reliability, safety, information
traceability, etc.
The CITyFiED project aims to enable the replicability and mass
-market deployment of energy-efficient retrofit of districts.
Therefore, taking in advance the successful CITyFiED
demonstration cases, in the cities of Lund (Sweden), Laguna de
Duero (Spain) and Soma (Turkey), the methodology use them
as a reference and a opportunity to validate and refine it
through the active participation of the CITyFiED network of
cities, assuring its flexibility and adaptability to different
Once the actions are commissioned, the SEP will be deployed,
in order to assess the overall performance of the intervention.
