Thermal Behavior of Exterior Coating Texture and Its Effect on Building Thermal Performance

The building envelope is the barrier between the interior and exterior environments. External wall coating might be used to improve the walls performance and how to specify it to meet these requirements for optimal energy performance and design efficiency providing eco-friendly surroundings. This chapter discusses the thermal behavior of the exterior walls with different coating textures inspired by traditional architecture in the great south desert of Algeria. The research work aims to evaluate the thermal and energy performance of wall facades with different exterior coating textures through the site experimental study. The first series were focused on surface temperature measurement using thermal imaging, in order to assess and evaluate the effect and thermal behavior of the exterior coating texture on lowering surface temperature. Meanwhile the second series of this study aims to study the effect of the textures already tested in the first experimental with the incorporation of three types of particles such as palm particles and pneumatic waste as a cement mortar aggregate into the already tested walls. The experimental results revealed that the integration of palm trees particles as a cement mortar aggregate into the textured facades is beneficial in optimizing the thermal behavior of the building envelope.
