Future energy demand for public buildings in the context of climate change for Burkina Faso
TL;DR: In this article, the authors discussed current and potential future energy demand for public buildings air conditioning in the context of climate change and highlighted the fact that the predicted mean temperature using climate change SRES scenario B2 will increase by about 2°C by 2050 which can cause a significant increase in air conditioning energy consumption.

Influence of internal and external boundary conditions on the decrement factor and time lag heat flux of building walls in steady periodic regime
TL;DR: In this paper, the authors investigated the dynamic behavior of opaque components of the building envelope in steady periodic regime using parameters defined by the fluctuating heat flux that is transferred in the wall, which allows for the joint action of the loadings that characterise both the outdoor environment and the indoor air-conditioned environment to be taken into account.

Effect of the insulation materials filling on the thermal performance of sintered hollow bricks
TL;DR: In this paper, the authors proposed the insulation materials are filled into the cavities of the sintered hollow brick to replace the single insulation layer, and the typical walls constructed by the hollow brick filled with EPS in cavities are built and wall thermal performance is numerically analyzed.

The influence of the external walls thermal inertia on the energy performance of well insulated buildings
TL;DR: In this paper, a parametric analysis was performed in progressive steps, by running the models of a virtual Test Cell and of a sample building, to calculate the associated achievable energy savings, and it was found that thermal inertia effects are enhanced if it is coupled with other energy saving measures and an efficient building use.
