The present work studies the Barra–Costantini passive solar heating system, with particular emphasis on the aspect of economics. The system which is studied is developed by Barra and Constantini. This system seems to be well adapted to the climatic and economic conditions in Algeria. In the...

In northern Algeria, use of ventilation by ceiling fans is widespread in mosques and other public buildings during the hot season, but is seldom used in private houses. In the first part of this study, the impact of this mode of cooling on indoor thermal comfort is investigated. A thermal...

Discontinuity in solar energy makes it so we have to use storage energy systems to respond to the energy need. The present paper shows an experimental study about sensible energy storage in a rockbed which is contained in cylindrical ducts disposed horizontally beneath the soil in a tunnel...

The optimal design of the renewable energy system can significantly improve the economical and technical performance of power supply. In this paper, the technical-economic optimization study of a stand-alone hybrid PV/wind system (HPWS) in Corsica Island is presented. Therefore, the primary...

This paper deals with design of hybrid energy system consisting of wind and photovoltaic with battery storage. A diesel generator is added to ensure continuous power supply and to take care of intermittent nature of wind and photovoltaic. The paper reports results of the technical-economic...
