The use of low thermal conductivity materials plays an important role in
the construction of energy-efficient buildings. Indeed, the improvement of the
thermal properties of building walls reduces energy consumption. This study
aims to determine the thermal and energy balances of a building enveloped with
Typha australis on the one hand, and a building without Typha on the other hand
(a building constructed with conventional materials) using the commercial
software Visual TTH. The results of the heat loss calculations show that the
Typha building is 62% more efficient than the conventional building. Also, the
studies on air-conditioning needs resulted in energy savings of 1577.136 kWh
per year for the Typha building, i.e. 1219 kg per year of CO2 avoided
in the air according to the SENELEC emission factor 0.773/MWh in
Senegal.
