ABSTRACT: Thermal comfort is one of the most important requirements that scientists
and building designers must meet to ensure the indoor air quality knowing its
importance on productivity and the health of occupants. However, it has never
been of great concern for architects and architectural historians and seldom
explores it. Buildings are the large consumer of the most energy consumption
(around 40% worldwide) and generate around 35% of GHGs like CO2 that
leads to extreme climate change. Hence, general and specific eco-friendly
solutions in the field of building construction are required. Analysis of this
study shows that air conditioning consumption can be significantly reduced
thanks to the compressed earth bricks and by taking into account the climate
and the orientation of the facades. However, this paper establishes viable
low-cost option of building energy consumption while maintaining the thermal
comfort and good indoor air quality. This work explains the effect of a single
residential room orientation, by reducing the
thermal amplitude, and improving the thermal phase shift in Ouagadougou climate conditions in April. Internal temperature was modelled with 8 cardinal
orientations. The result corresponds to a decrease of thermal amplitude damping greater than 4°C between East-West and
North-South sides and, with a thermal phase shift of 4 hours 30 minutes between the Nord and West walls.
