The façade is one of the foremost imperative impacts on indoor thermal comfort, because it directly controls the amount of natural lighting and passive heat gains that enters a building’s interior. This means it has a crucial impact on the thermal comfort of the users (occupants) and indoor environment. Ultimately, this research contributes to the question of how a building curtain wall façade have an impact on indoor thermal comfort. To study the thermal comfort in curtain wall façade office buildings with naturally ventilated, a field study was carried out for two months on four office buildings to evaluate indoor thermal comfort in Addis Ababa. This study was based on the adaptive model of ASHRAE-55. Findings suggest that the four office buildings perform differently in terms of thermal comfort (based on field study), environmental parameters (air temperature, mean radiant temperature, relative humidity, and air velocity) and surface temperature. As a result, the building 1, 2 and 3 shows thermal discomfort to the indoor environment during a period of extreme heat, compared to building 4. It is postulated that the higher surface temperature will cause higher indoor temperature levels in all buildings, except building 4. In both months a maximum of 30.6°C, 29.6°C, 28.3°C and 25.7°C of indoor ambient temperature for Building 1, Building 2, Building 3 and Building 4 have recoded respectively. The large temperature differences also have the expected consequences on indoor relative humidity fluctuation. The relative humidity value ranges from 16% to 71% in all 4 buildings. Most of the time air velocity that within buildings is generally less than 0.2m/s, which is generally unnoticed. The temperature difference between surface temperature and indoor temperature is between 11.2°C and 25.2°C. At the maximum exterior surface temperature of 55.5°C, at same time maximum indoor temperature recorded which 25.2°C. The study benefits architect, designers and construction managers by broadening the perspective of the field toward using a more customized optimization framework in early design that will further guarantee the requirements of sustainable indoor thermal comfort in office building development.
