The Renewable Energies Development Center (CDER) is a research center resulting from the restructuring of the High Commissioner for Research, established on 22 March 1988. The Solar Equipments Development Unit (UDES) was created in 1988 , UDES has been integrated into the EPST Renewable Energies Development Center (EPST / CDER) It is a scientific and technological public institution (EPST) responsible of conducting research and development programs, scientific and technological, of energetic systems using solar, geothermal and biomass energy. The CDER as a scientific center, actively participates in the national program for research and technological development, as defined by law and policy program at five-year projection on scientific research and technological development. The national programs selected on this program are focused on economic and social priorities in order to meet the strategical needs for the economical development. The CDER, since its creation,works on the application of this strategy through the deployment and integration of several projects and pilot projects at national level. The CDER with its research teams and its three research units including Solar Equipment Development Unit (UDES) Our areas of expertise include: – Solar-powered solutions for sustainable buildings and infrastructure, – Water desalination and wastewater treatment using solar energy, – Innovative bio-based and sustainable insulation materials. – Hydroponics and solar energy in agriculture OUR MISSIONS :  Carry out design, sizing and optimization work on renewable energies equipments for the production of heat, electricity, cold and water treatment;  Carry out all studies and research of technological processes development for manufacturing prototypes, equipment and pre-series;  Establish technico-economic and engineering studies to set up pilot installations in order to ensure the transfer and mastery of new technologies;  Set up characterization, testing, quality control and compliance techniques, in order to ensure the qualification, approval and certification of the developed equipment. The expertise and know-how you could bring to a project : Our areas of expertise include: – Solar-powered solutions for sustainable buildings and infrastructure – Hydroponics and solar energy in agriculture – Solar powered HVAC systems Mention the most relevant projects in which you've been involved : UDES-CDER has been actively involved in numerous international, European, and ARICA projects. Notably, during previous LEAP-RE, LEAP-SE and NextMed calls for projects, UDES led and participated in initiatives and projects, focusing on renewable energies, smart microgrids supporting sustainable development across energy, water, and agriculture sectors. Moreover, UDES has spearheaded national projects.
