Through this work, we expect to answer the following question: What innovations and technological improvements can be made to the building sector in Niger to make it less energy-intensive and less destructive of the ecosystem? To achieve this, the following activities were carried out: bibliographical research, data collection in the field, data analysis and, finally, project proposal. The book is divided into four main sections.

The first part sets out the issues guiding the study and proposes a number of possible solutions. We present a brief overview of the current situation.

We then set out the importance of the subject and the expected results. The second part, which is purely theoretical, focuses on a literature review.

It presents summaries of the titles that inspired us for this study. We have analysed them, identified the substances we have drawn from them and briefly commented on our results.

The third part outlines our method for achieving the expected results. The last part, before the general conclusion, deals with the project itself.
