Construction of a typical residential villa on the campus of the National School of Architects in Rabat to demonstrate energy savings, ecological benefits and improvement of living comfort in such buildings in costal regions. The target is to show that the higher investment costs of the low energy house compared to a standard house will be paid back by lower energy consumption.

At the same time the pilot project will be used to train students of the school who will promote this type of building towards their future customers. It is planned to derivate another type of residential home for the dry continental climate inside the country.

The energy concept is based on passive design measures and on the use of renewable energies including solar thermal and an electrical air / water heat pump for heating and cooling purposes.


Compared to a conventional building, energy savings of nearly 75% are achieved with the pilot project. Even if the initial investment costs are more than 20% higher than for a standard urban villa, they are paid back within less than 10 years, which makes the project and economically attractive solution.


Main technical features of the Pilot Project

The energy demand of the house for heating as well as cooling - compared to current building practice - is reduced significantly by insulation, shading and the use of internal mass for heat/cold buffering. The reduced remaining energy demand is covered by an efficient combined solar/heat pump system, together with a night ventilation system. This will assure a constant indoor climate throughout the year.

Passive measures with high/moderate cost-efficiency:

  • insulation of building

  • overhang shading elements

  • use of internal mass for heat/cold buffering

  • natural night ventilation

Active measures

  • solar water heating

  • electrical air / water heat pump for space heating and cooling

Main results of the Pilot Project

Compared to a conventional building energy savings of 74% are achieved in the Pilot Project.

Due to relatively high energy prices in Morocco, the MED-ENEC pilot project has already a reasonable cost-efficiency with a pay back period of approx. 10 years (graph 1)

When benefiting from learning and scale effects in the framework of a large building program, and if using only the most cost-efficient technologies, the "replicable solution" becomes a profitable investment (graph 2)

Additional advantages that are difficult to quantify comprise reduced needs for energy subsidies and energy imports as well as environmental and health benefits.
