PROJECT SUMMARY

Achieving the European Union’s 2020 energy efficiency targets and at the same time reducing its

dependency on energy imports is a huge task that requires innovative approaches and tools – such

as the ones Trust EPC South wants to provide.

The Trust EPC South project aims to unleash the tertiary sector market potential for energy

efficiency investments in Southern Europe by developing a new investment assessment instrument

backed by an established building rating methodology (Green Rating™). Such instrument shall support

energy service companies (EPC providers and facilitators), financing institutions and tertiary market

actors thanks to the application of a standardised methodology to the investment assessment and

decision processes, ultimately allowing to reduce barriers to energy efficiency investments.

Trust EPC South, a project financed by the European Union’s Horizon 2020 programme, will pursue

its ambitious objectives in Portugal, Spain, France, Italy, Croatia and Greece. The project

consortium, led by the Spanish firm CREARA, is composed by interdisciplinary experts representing the

participating countries and by the international non-profit organisation Green Rating Alliance. The

partners are united by the common intent to stimulate investments in the target markets, which are

offering great opportunities for energy efficiency as well as energy performance contracting.

INTRODUCTION

Within the scope of Trust EPC South, the project consortium initially conducted a thorough market

analysis in the six southern European participating countries. This analysis includes an advanced state

of the art of sustainable energy solutions for the tertiary sector and the characterisation of the

corresponding tertiary sector segments, the assessment of market barriers as well as the presentation

of available financing solutions. It also includes the evaluation of the most promising sustainable energy

projects or “best practices”, which are presented in this report.

These best practices have been used to generate standardised sustainable energy project technical

functional models that have been used to develop the GREPCon tool. Thirty three (33) factsheets are

presented in this report to show which are the most common solutions used and outline how they are

being implemented, how they are financed and what are the other conditions for success.

Additionally, at the end of the project, this document has been complemented with 46 factsheets

describing the pilot projects identified and supported by Trust EPC South’s in the six participating

countries.

The factsheets cover the main tertiary sector segments: Retail, Health, Hospitality, Offices, Sports

Centres or Education. Since the purpose is mainly to highlight the most promising sustainable energy

solutions, and due to the challenging EPC market conditions in the participating countries, not all of the

projects chosen involve EPC contracts, but also other more traditional arrangements such as energy

supply contracts or turnkey projects.

They also cover a wide range of measures, from boilers’ replacement to optimisation of energy

management systems, energy monitoring tools, and the installation of renewable energy sources. The

interventions on the building envelope are less represented due to their long investment recovery times.

For each factsheet, a set of over 20 indicators is provided, divided into four areas:

• Introductory information including segment of activity and stakeholders involved;

• The project’s context, where the facility and initial situation/energy use are described;

• Specifications of the contract: including duration, planned savings, contractual details, financing

arrangements and results;

• Additional comments have also been added when relevant to further detail the project and its

specificities (elements for success, advantages for the clients, etc.).

The choice of the indicators has been made to create synergies with existing initiatives such as

TRANSPARENSE and EESI2020, but also to give a comprehensive overview and thus reinforce our

analysis on potential EE and RES applications in tertiary sectors. One important criteria used in the

selection of the best practice cases is their replicability, as one aim of our work is to stimulate the

development of further implementations.
