Green Building Models for Climate Change Adaptation and Mitigation in Urban Areas of Benin: Case of Natitingou and Parakou

Abstract

The aim of this study is to develop models of green buildings ensuring the efficient management of energy, the greening of urban areas, and then the adaptation to global warming and the mitigation of this global warming in the urban areas of Natitingou and Parakou. To achieve this objective, we went through data collection, site analyses, the design of green building models and their analyses. For the data collection, different methods have been used such as: observations, measurements, pedestrian crossings, map analysis, model analysis, site analysis and internet searching. Climate data, Population data, sun system data and vegetation data are analyzed respectively with climate consultant software, Microsoft excel, Rhino grasshopper and iTree tools. The design is done with SketchUp. The result from the analyzes of the models shows that they are rentable in term of energy, comfortable (100% in Natitingou and 86% in Parakou), adapted to the increase in urban vegetation (60% of the built area), carbon sequestration (1.818 thousand tons of carbon in Parakou and 579.1 tons of carbon in Natitingou per year), carbon storage (27000 tons of carbon in Parakou and 8600 tons of carbon in Natitingou), Oxygen production (4.848 thousand tons of oxygen in Parakou and 1.544 thousand tons of oxygen in Natitingou per year) and then to the adaptation and mitigation of climate change.
