Mediterranean Action Plan

ENERGY AND SUSTAINABLE DEVELOPMENT IN THE MEDITERRANEAN
cover all developments. Therefore five different baselines were used to analyze all energy
system components:
Diesel water heaters were considered as the baseline for technologies involving supply
of hot water such as the domestic and non-domestic solar water heating systems;
Electricity was considered as a baseline for solar thermal technologies for heating and
cooling as well as for industrial process heat;
Butane gas lamps were considered as the baseline for lighting in rural and decentralised
areas, this baseline was used in PV Solar Home Systems for the Bedouins;
Gas based electricity generation and grid extension was used as the baseline in the
analysis of technologies such as wind electric generation, hydro electric, hybrid electric,
solar thermal electric and waste-to energy power plants;
Gasoline generators were used as the baseline for off-grid professional applications of
PV, PV pumping, health and education systems etc.
3. Examples of good practice, case studies
3.1 Case Study 1
Install Hot Water Solar System for IbnAlwaleed Hospital In Homs City
3.1.1 Overview
Following the National Strategies aiming to widespread renewable energy applications,
especially solar hot water systems, the decision had been taken in NERC in cooperation with
Ministry of Health to execute a project to install solar hot water systems in all public hospitals
starting from IbnAlwaleed Hospital in Homs.
A technical committee created to identify the hospital needs of hot water, and the technical
specifications of the system required to cover that need.
The technical committee issuance a Term Of Reference to be announced as a local tender,
this results three offers tow of a private solar systems manufacturers and one of a
governmental manufacturer.
All offers studied technically and financially according the TOR and the decision taken to
choose the governmental manufacturer (Mechanical and Metal Structure Company) for these
reasons:
1) According to test reports asked from the whole offers, the optical efficiency of the
collector of the Mechanical and Metal Structure Company was the best and equals 76%.
2) The company had a good experience to implement central solar water heating projects.
3) The absorber of the collector used from the company is imported from Greece and
painted with selective coating.
4) The financial offer seems reasonable according to other offers.
NERC instructed the company to start installing works in the hospital.
3.1.2 Project Description
The hospital consumption of hot water estimated as 6500 L/day, so the collector area
collected equal to 120 m 2 divided into three groups, each group has a 2200 letter tank
provided with double jacket heat exchanger, and the circuit between collectors and tanks
works with a pump working regarding a deferential controller.
3.1.3 Projects Indicators
Technical Indicators:
Renewable energy delivered (MWh/year): 58.28
Net average GHG reduction (tCO2 /year): 31.37
Solar fraction: 93%
