Business Model – Financial scheme

• Private model of shared risks

• Partnership between ESCO and Building company

• Partly granted by European Commission

• The investment is covered by the companies

• The payment is returned by the Owners along the contract life span

• The owners keep the same monthly fee.

Phase II (912 owners) 20 years 15 years

Business model - Contracts

Non – Technological barriers

• Legal:

• Finance.

• Social.

• Spanish legislation against electrical self consumption

• High upfront costs,

• Long pay back periods

• Need long term contracts > 15 years

• Private multi owners,

• Citizens distrust companies

• Lack of acceptance for building renovation work

• Lack of knowledge and interest among residents about energy efficiency

Success factors

• Legal:

• Finance.

• Social.

• Use of both regional and international fuels, more stable price

• EU support made the renovation possible without raising the energy bills

• Communication strategies

• Constant communications (Contact point)

Business Model – Lessons learnt

• Innovative financing scheme: Public (EC), Private Companies (ESCO- Construction), Banking(Private green banking), Owners (1488 dwellings)

• Classical financial entities. Do not see the energy savings as a guarantee to endorse retrofitting projects

• Large scale renovation project towards NZEB are only possible with long term financing schemes

• Close partnership between different entities

• User knowledge and citizen engagement

Strategic Plan for Laguna de Duero as example of CITyFiED Methodology implementation

In order to establish a new vision for the city, there are three important questions to answer:Where are we? Where do we come from? Where do we want to go?

Phases for the Strategic Plan development:Understanding the city and goals definition

PHASE1.

Identification of current problems and needs.

PHASE 2.

Integrated Strategy Analysis

How? • Meetings/interviews with stakeholders• Participative process with citizens • Data collection and validation

ResultDefinition of the city priority issues or areas inwhich actions are needed to accelerate thetransition towards a sustainable urban development

CITyFiED METHODOLOGY

The goal of these phases is to identify the

current situation of the city and establish

general objectives for a long term Strategic

Vision that will guide the transition to a

smart, sustainable and inclusive city.

In these phases the StrategicVision

of the city is defined and, according

to the established targets, a set of

actions is proposed

PHASE 3.

Development of Action Axis and identification of potential financing opportunities.

PHASE 4.

Definition and prioritization of the interventions

CITyFiED METHODOLOGY

How? • Analysis of the results obtained in Phase

1 and 2 • Meeting/interviews with stakeholders• Analysis of existing plans and strategies

ResultProposal of a set of actions according to the newStrategic Vision for the city

Phases for the Strategic Plan development:Proposal of a set of actions and its prioritization

Action axis proposal

1. External comunication and positioning

2. Productive model

3. Sustainability

4. Environment

5. Citizens welfare

6. Demography

Housing renovation in order to improve living conditions and

energy efficiency.

Proposal of energy efficient interventions in buildings, facilitating the implementation of green roofs and "District Heating" (district heating), among others.

Implementation of Energy audits in public buildings

PHASE 5.

Definition of indicators for monitoring and evaluation

In this phase the goal is the definition

of a set of indicators that allows the

assessment of the actions that will

be implemented in the future.

CITyFiED METHODOLOGY

How? • Analysis of the proposed actions • Definition of the impact assessment evaluation • Meeting/interviews with stakeholders
