ALG - EGY - ISR - JOR - LEB - MOR - PAL - SYR - TUN - TUR MED-ENEC pilot projects
The following diagram shows the primary energy savings, the incremental costs and the pay back periods of the realized MED-ENEC Pilot Projects. 
The graph above shows a great diversity of the approaches. Thus, in the Lebanese PP the main focus was on the implementation of cost effective measures, which leads to a pay back time of 1-2 years with moderate primary energy savings of 14%. On the other end, the touristic resort in Tunisia follows the approach to demonstrate an almost energy neutral project, with high incremental investments but also high energy savings. Especially PP with very high savings have relatively high pay back periods which might not be accepted by all private investors. Replicable
The Replicable pilot project illustrates the cost effective solution, which is including only those measures that are highly cost-effective (a smart mix of measures implemented) and replicable on a large scale. Measures with high research & development character are excluded.
(please note, that the PP in Egypt and Lebanon are refurbishment projects and thus have no or only limited costs for the conventional solution, therefore the share of the incremental costs was set per default to zero)
With the exception of the Algerian PP (with a negative net present value) on the one end and Lebanon on the other end (due to the focus on cost effectiveness in a privately owned hospital), all projects are financially viable, where the pay back periods range between 4-12 years with energy savings of 34-85%. Macro Economic
Pilot projects which are not cost-efficient due to the national subsidized energy prices, where analyzed under another macro economic situation. Here the national energy prices where changed with "appropriate" regional energy prices
On a macro economic perspective all projects are financially viable.ConclusionIf an appropriate technology mix is decided the cost-effectiveness of these investments is quite attractive, so that pay back periods below 10 years are achievable - Countries with very low energy prices need to provide incentives for these measures, since otherwise pay-back on investment is unacceptable. (e.g. ALG, EGY)
- Markets for energy efficiency and renewable energy technologies are not yet mature. It is the task of the governments to support market transformation, e.g. through standard setting or procurement policies
