TRNSYS Software Used for the Simulation of the Dynamic Thermal Behavior of a F2-building in Lokossa City in Benin Republic

The present study was based on the use of TRNSYS software for the simulation of the dynamic thermal behavior of a F2 building in Lokossa, Benin Republic. The results showed that between 00 AM and 07AM, the temperature of the indoor air is approximately 20 ° C and increases gradually until 02 PM when the temperature reaches its peak 30 ° C. However, the total incident solar radiation receives varies from a face to another and the roof received the largest due to its horizontal orientation. The heat received by a face reaches its peaks dependently on its orientation. There is a phase shift in the heat transfer received by the envelope. This is possible due to the thermal inertia of the envelope’s constituent materials, property that allows the building envelope to dampen the heat received and to phase out the transmission time to ensure thermal comfort in the home.
