Malta is the largest island in Malta archipelago. Valletta, the capital, is the cultural, administrative and commercial centre of the country.
Gozo is the second largest populated island, and is topographically quite different from Malta.
The diagnosis of the pilot building has been carried out based on the following procedure:
- on-site energy audit in order to evaluate the different parts of the building (insulation, windows, heating system...)
- building energy performance evaluation, based on the collected information
- identification of the feasible solutions
An energy auditor conducted a survey of the 35 pilot households and analyzed each household’s energy bill. The inventory of the main electrical appliances was made in each household, including their power rating.
The auditor also interviewed the residents asking them about their energy usage and consumption patterns. He recorded all the data in a speadsheet, which automatically calculated an estimantion of the energy consumption. These calculations were then reconciled with the actual energy consumption obtained from the utility bills.
Based on the collected energy consumption date, the auditor made an analysis of possible low-cost building retrofotting measures that will decrease the energy expenses of the households. Together with the retrofitting measres identified, the analysis outcomings included also a list of investments which can be made in each households in order to reduce the energy consumption.
Those pilot buildings were typical buildings constructed in 1920-1990, from energy consumption point of view, the buildings were characterised by following features:
- roof of the buildingswas in concrete and covered by a bituminous waterproofing membrane
- all the windows were single glazed with aluminium frames and had no external shading elements
- the pilot buildings were mainly independent, almost all walls were exposed, resulting in higher losses
The analysis of domestic heating in Malta showed that:
- most households did not have heating systems installed.
- domestic heating is often based on the use of one or two portable gas or paraffin heaters, and only during the period between December and March
- some measures possible in other countries might not be taken in Malta
- indoor temperatures are low. Measures such as insulation and double glazing should improve comfort levels rather than reducing energy consumption
- savings achievable in other countries might not be achievable in Malta
During energy audit, annual electrical consumption over the period June 2012 to June 2013; electrical consumption was breakdown on main appliances/functions, taking into consideration Power, Quantity of appliance, Daily Operating Hours, Days in Operation and Annual consumption/function. An example is downloadable below.
The energy performance of the building before refurbishment was classified as E or F.
The following table shows the identified energy efficiency measures after energy audit.

To ensure the success of the pilot projects, a participative process is exploited to involve actively local relevant stakeholders in the large scale pilot experimentation. The two main elements of the participative process are:
- the Territorial Management Group (TMG), composed by local key stakeholders, in charge of analysing innovative financial options and technical solutions, and
monitoring the implementation of pilot projects.
- the Pilot Project Participative Group (PPCG): grouped by direct/indirect beneficiaries of the pilot projects, expresses the real needs and problems experienced in
the buildings selected as the pilot projects. The PPCG is able to help the TMG to develop and adjust the pilot project action plan based on the real needs.
For implementing ELIH-Med pilot project, different PPCG meetings were organised in Malta.

Monitoring was the unique activity running throughout ELIH-Med project implementation; it was very important for:
- supervising the project implementation,
- collecting energy consumption before and after pilot energy refurbishment and smart metering experimentations
The objectives established for the pilot project in Malta are:
- to implement energy-saving technologies and construction techniques in low income housing
- to assess the cost-effectiveness of the various technologies and techniques
- to identify any barriers with energy-efficient technologies and measures to tackle them
- to demonstrate the effectiveness of energy-efficient technologies and measures and promote greater uptake in low income housing
Therefore, monitoring was a key factor to verify the objectives/results obtained and evaluate further the sustainability of the project.
To evaluate retrofitting, the energy consumption monitory was made through different methods:
1. all households of selected dwellings supplied copies of their electricity bills for the last two years; the bills were sent by
the utility company every six months. The households will continue to provide MIEMA with copies of future bills until the
2. a subcontractor was in charge of taking monthly consumption readings of electricity and gas cylinders.
Moreover, temperature readings were taken at three points in 10 households – external, internal under roof insulation, internal not under insulation.

Calls for public tenders are procedures applied to generate offers from companies competing for works, supply or service contracts in the framework of public procurement. This procedure creates a mutual benefit that the service providers who win the tender can have the opportunity and experience of cooperating with EU program and meanwhile with the sufficient procurement provided by the tender, the pilot projects can be carried out smoothly.
Generally, a typical invitation to tender template is formed with the following sections: Introduction, Project background, Legal issues, Maintaining issues, Supplier response required, Timetable for choosing the supplier and Requirements.
Regarding the selection of energy retrofitting providers, besides an overall perspective the advantage in economic aspects makes a supplier more competitive.
For implementing pilot projects in Malta, the activities related to public call for tender includes:
• preparing the call for tender documents in the respect of the Malta public market law
• launching the public call for tender for consultants to assess buildings and prepare plans for energy efficiency improvement interventions
• launching the public call for tender for selecting providers of retrofitting implementation
• evaluating cost, experience and technical criteria
• qualifying specialists/project developers
The call preparation was made with local councils; and the calls were advertised in the media.
The different calls were made: for PV systems, for solar water heaters, for other energy retrofitting measures; as well as for energy consultants. As good practices, two of the calls prepared by MIEMA are downloadable below.

Based on the energy audit and the preliminary analysis, before the pilot experimentation, 35 pilot dwellings were classified as Energy Class E o F.
The following table shows the identified energy efficiency measures.
Energy retrofitting plan was well defined for each dwelling. Most pilots applied 2 or more of the following:
• PV systems (in total 30 installations)
• SWH (totally 22 installations)
• Roof insulation (in total 28 installations)
Other measures include:
• Solar film on glass
• Roof reflective paint
• High?efficiency a/c
As a good practical example, one of those plans is downloadable below.
It was expected for all Malta pilot dwellings to improve the building energy performance by two or more classes.

Smart metering activity
ELIH-med focuses its attention not only on energy efficiency improvement in LIH, but also tries to change the behavior and consumption patterns of tenants and owners of LIH; measures to modify energy behaviour will also be extensively explored and tested through a large scale experimentation of multi-energy smart meters.
The aim of the smart metering experiment is enabling an increase in energy efficiency by providing LIH consumers with information to help them change the behavior and reduce the amount of used energy.
The proposed experimentation plan for smart metering in LIH is putting consumers' interests at the front of the experiment. This involves education and engagement of consumers to better manage their energy use, to raise awareness and understanding of the benefits that smart metering is enabling.
Nature and frequency of interactions
Theoretically the nature and frequency of interactions with LIH users (monitoring) for a coordinated return of experience should be divided into four time periods. These can be distinguished as separate phases of smart metering experimentation including period before smart metering equipment installation, installation, monitoring period and the closure of experiment with evaluation of final data.
Phases of smart metering experimentation and interactions with LIH consumers will follow the ELIH Med project plan as shown below.
Thet first two periods were “key” phases of the implementation process while monitoring phase will include additional awareness campaigns.
A key event of the consumer experience of smart metering will be the installation visit, which will ensure consistent messages for end-consumers about what to expect and to help facilitate the longer-term behavioral change necessary to deliver project benefits. Suppliers of smart metering equipment will therefore be obliged, to provide consumers with information on how to benefit from their smart meters and to provide appropriate support to different social groups (through call for tender). Special attention should be to vulnerable consumers with customization regarding Age, Social status and Type of dwelling.
Interactions and stakeholders
Stakeholders involved in Smart Metering experiment included Equipment Suppliers, Utilities, Installers, ELIH Med specific woring groupes' coordinators, TMG and PPCG.
The PPCG also played a key role in the monitoring and evaluation stages of the project. PPCG included social workers and civil servants with experience in working area where the pilot project took place, local groups and associations and social landlords. And it should also include the following key actors: Representatives of Local authorities (Municipality, local energy agency, etc.), Local associations and NGOs committed with energy poverty.
A summary of the experimentation plan on partners’ territory for smart metering in LIH and the smart meter selection criteria are downloadable.
Smart metering pilot experiment in Malta
As part of the project, 15 households were chosen for Smart Metering (SM) experiment, 10 households taking part in the pilot project and 5 households not. In these 15 households smart meters have been installed for energy consumption monitoring.
In particular, the following meters have been installed in the households,
- Central electricity metering (Efergy Energy Monitoring Sockets): 1 device per household with wireless connection to monitor which is located in a prominent area in
- Appliance electricity metering (e2 classic): 4–6 devices per household attached to socket outlet with display of current and cumulative consumption of a specific
- “Smart Metering Workbook” was provided to Tenants. This workbook included the explanation of ELIH-Med Smart Metering experimentation and a consumption
calendar. Workbook calendar was created so tenants could write down themselves the daily consumption of their households. This process helps them realize how
much is their daily consumption and how much money they are spending each day.
- A manual was provided with each Smart Meter installed. It was overviewed with the tenants during installation and a brief explanation of system was given to the
Smart meterring experimental activity in Malta included also:
? Metering of consumption of 6 individual units per household (e.g.Refrigerator, a/c, water heater, etc) was carried out
? Metering of total consumption with monitor for residents to view instantaneous and cumulative consumption
? Residents were supplied with an internet hub which allows monitoring of consumption from a PC or mobile device.
? Meetings were held with residents to prepare a detailed report on their consumption behaviour and recommendations for changes to reduce consumption
Dissemination awareness and national project capitalization
ELIH-Med Capitalization and long lasting effects
What is capitalisation?
In the framework of European cross-border cooperation projects, capitalisation is a mean to exploit commonly the results of several projects and ensure long lasting effects. Capitalisation could be defined in a general way as the strategy and process that will allow to ensure a long term, deep and concrete impact of the project activities and results on public policies at local, regional, national and European level.
ELIH-Med capitalization strategy
Capitalisation is a mandatory activity in ELIH-Med, defined in the terms of reference of the first strategic call for proposals of the MED program.
The objective of ELIH-Med Capitalisation is broader than ELIH-Med scope and it covers all the initiatives that share some of the preoccupations and objectives of ELIH-MED. Above all, a capitalisation process aims at creating a cumulative effect, not only on the basis of the aggregation of projects results but also at a program level through the convergence of indicators, strategic objectives and proposals to strengthen cooperation process impacts within the mainstream framework of European policies.
Within the context of the project, an awareness campaign has been developed for the promotion and dissemination of energy efficiency in low income housing occupants.
Objectives of the campaign:
- to communicate the EE measures and tips that exist for both individual apartments and residential buildings.
- to communicate the financial mechanisms that exist to fund aforementioned EE measures.
- to develop activities that strengthen the feeling of “belonging” to the community/neighbourhood, in order to
promote energy refurbishment at building / district scale.

Policy paper and Ljubljana declaration
ELIH-Med capitalisation activities are framed in general by the
EU2020 strategy and the discussions about the next programming period priorities. They try to fit with the pan-European objectives and they also constitute inputs for the 2014-2020 operational programs.
The two main outcomings of ELIH-Med capitalisation activity are
Policy Paper and Ljubljana Declaration.
Since the beginning of the project (April 2011), ELIH-Med has associated with another MED strategic project dealing with energy efficiency in buildings, MARIE
, in order to have a common message to deliver to policy-maker. The main outcome of this joint capitalisation process is a Policy Paper
aiming to improve Med transnational cooperation answers to energy efficiency challenges in buildings. PROFORBIOMED
project has joint the process, and a cooperation agreement between the three projects was signed in November 2012.
On 23rd and 24th October 2013, the annual event of the MED Programme was held in Lisbon. On the occasion, the Ljubljana Declaration was signed jointly by the lead partners of the 3 strategy MED projects - ELIH–Med, Marie & PROFORBIOMED.
The targets of the Declaration are:
- European Institutions: European Commission, European Parliament, CoR
- Mediterranean member States
- Regional and Local Governments
- Management Authorities of EU Programs
- Network of regional and local authorities: CAT-MED platform, Covenant of Mayors
Specific proposals have been worked out for each target group.
