Abstract
Indoor thermal comfort is an important feature of sustainable building and is necessary for a
safe indoor environment. In terms of thermal comfort, condominium building expectations,
tolerance, and preferences vary across Addis Ababa's climate zones. As a result, the purpose of
this study is to assess the internal thermal comforts of condominium residential houses in Addis
Ababa, Ethiopia. Subjective and objective measurements were used in this investigation by
collecting a cross sectional data from a sample of 130 condominium residents from September 4
to 12. The ASHRAE seven-point thermal feeling scale is used to determine the subjective
measurement. To assess interior thermal comfort, an adaptive comfort model was used in
accordance with the ASHRAE standard. In terms of thermal sensational votes between 1 and +1,
50.9 percent of respondents at Tsion condominium are content with the internal thermal
environment, but 25.4 percent of respondents at Gelan condominium houses are. Similarly, 45.6
percent of Tsion condominium residents said they would want their properties to stay the
same or only be slightly colder or warmer. Condominium houses in both hot and cold
climates were, on average, not in conformity with the adaptive comfort standard's 80
percent acceptance zone. As a result, policymakers in the construction sector should
address issues of thermal comfort in future planning.
