Demonstration site | Medersa Rachid | ||
Typology | Public building (ancient Madrasa) now abandoned. The Old Building will become a Building Training Centre.
Old school (Madrasa Rachid) from the XVII-XVIII century, traditional brick construction, with plaster on the inside walls. The building is made up of small individual cells (10 mē) organised around the central courtyard (180 mē). On the South, near the canal, the building has two levels of cells.

Innovation in planning and architecture
Objective of the refurbishment : associate traditional construction methods with energy efficient design, Bio-climatic design (Natural ventilation, plantation of vegetation, ...) to reduce overheating in summer in order to avoid the use of air conditioner, which are more and more used in this region,
Use of traditional building structure, called Iwan, which is a kind of pergola made of dried clay, and use it as an energy efficient device (concept of technological Iwan).
A 3D model of the Medersa is at present in creation at the School of architecture of Lyon. The 3D model will give a good overview of the final aspect of the Medersa at the end of the refurbishment:
outside ambiance : view of the vegetation and of the technological Iwan to reduce overheating in summer
inside ambiance : disposition of rooms and degree of natural lighting
Definition of materials and components
Use of local and traditional building material like clay for the refurbishment of the Medersa to reduce the environmental impacts of the renovation.
Destruction of recent concrete part of the building that need lot of maintenance and are not sustainable
Use of high efficient lighting and electrical devices
Use of a high performance gas heating with basic design that can be repaired on site easily
Rainwater collection is planned
Passive moderation of the external temperatures using the thermal mass of the building is the traditional energy strategy. The project aims to optimise this strategy by the incorporation of modern design and technology.
Use and moderation of natural light by design of the use of the internal spaces as a function of the illumination needs of the relevant activities and the provision of fixed and mobile solar protection devices. Lighting control by use of vegetation and rooftop pergolas.
Cross ventilation between distinct facades.
Integration of renewable energies
Each building is fitted with an Iwan, which is a kind of pergola made from dried clay to create shading. The traditional Iwan of the Medersa will be replaced by a technological Iwan, in which will be integrated a 4.8 kWp photovoltaic system, which will produce around 7000 kWh yr.
A 43m2 solar thermal system will provide the domestic hot water of the training centre.
The monitoring will be composed of:
Thermal sensors to measure the ambient and inside temperature,
Energy meters for the consumption of electricity and for the production of the photovoltaic system,
Heat meters for the consumption of gas and for the production of the solar thermal system.
The monitoring system will be managed by one computer of the training centre, there will be a computer room with an access to the internet, which will be also used to monitor the performances of the building. The monitoring will be design to be very sustainable with very little maintenance needs.
