DESIGN METHODOLOGY FOR GREEN POULTRY HOUSES IN THE SAHELIAN ZONE

The chicken production sector is growing rapidly in Sahel. However, this sector suffers many losses due to heat stress in chicken houses. This article presents a methodology for designing a green poultry house to combat heat stress in the Sahelian zone. The methodology adopted is based on the development of a green design process and a multi-criteria evaluation approach. A literature review and surveys were first carried out to determine the ecological design standards. Next, design criteria and sub - criteria are identified. Finally, multi - criteria evaluation methods such as FAHP and TOPSIS were used to determine the weights and performance scores of each criterion and sub-criterion. The results obtained show that the health and quality of the indoor environment criterion is the first to be taken into account in the design with a weight of 0.54 and a performance score of 0.651, followed by the economic factors criterion with a weight of 0.29 and a performance score of 0.452, then the technical/cost factors criterion with a weight of 0.11 and a performance score of 0.435 and finally the choice of site criterion with a weight of 0.06 and a performance score of 0.423. In addition, the orientation of the building, health and safety, climatic conditions and the initial investment cost are the most important sub-criteria to be taken into account, with respective weights of 0.45, 0.49, 0.29 and 0.5.
