The solar domestic water heating system in the six Moroccan climate zones

Morocco has adopted a national energy strategy for the promotion of renewable energy and the energy efficiency. The building's sector is an area targeted by this strategy, since it is one of the major energy consumers in the Moroccan level. With a 25% share of final consumption countries (ADEREE) Its consumption is set to increase further in the future years. In addition the building is a strategic energy sector taking into account the long life of buildings. In this perspective, in order to establish a regulatory and legal framework governing the energy efficiency in the building sector, this regulation was based on several steps among them, the establishment of a climate zoning based on the degrees of heating-days and zoning. This zoning has left Morocco in six climatic zones. In this context, the present work aims to make a contribution in packaging useful climate data for the evaluation of the building thermal requirements, specifically the production of hot water. To achieve this goal, we developed a solar radiation calculation model for the six Moroccan climate zones based on the model of "Capderou". However, from these data, was developed another model for calculating the water heater solar performances and the production of domestic hot water in these different zones. This model is based on the platform "ENERBAT" Laboratory "LERMAB" at the University of Nancy Lorraine.
