The aim of this study was to carry out a dynamic simulation of the energy and environmental performance of a built space system, with a view to assessingits energy and environmental class. The use of a simulation and modeling tool, supported by various meth odological references, formed the basis of our approach. Adopting a systemic perspective, we described the structural and functional aspects of the systems making up built spaces, as well as the
associated energy flows. Our approach was also based on a typology, taking into account typical days, structural and functional configurations at different scales and angles of observation. The analysis tool we developed in Java was
applied to the built space system of the Patte d’Oie university campus in Ouagadougou. Annual electricity consumption was measured at 124387.34 kWh, closely aligned with the average annual electricity bill (125224.31 kWh), with a maximum relative deviation of 1%, followed by a carbon emissionbalance of 58337.66 kg eq CO2 per year. This validation confirmed the effectivenessof our tool. In addition, following the analysis of electricity consumption
using our tool, the university campus was classified in energy class
B and environmental class C. These results will be based on the emission factors
of the energy mix of the West African Economic and Monetary Union
(WAEMU) territory, with particular emphasis on Burkina Faso.
