    Building envelope vis-a-vis indoor thermal discomfort in tropical design: how vulnerable are the constituent elements?

    Abstract: Tropical climate is characterised with high temperature consequent upon high solar gains which in effect impacts negatively on the interior spaces thereby creating thermal discomfort for healthy living environment. This has resulted into adoption of various active and passive design techniques/approaches to ameliorate the indoor living condition. This article focuses on computer modelling of the heat transfer mechanisms into the building with a view to identifying which element(s) of the building envelope is/are most vulnerable. In doing this, a virtual model of a predominant residential building typology in the study area of Ogbomoso, Nigeria, is subjected to thermal analyses via DesignBuilder, a computer simulation package using Ogbomoso climatic data as obtained from a global climatic database, Meteonorm. Results of the analysis indicate Exterior Glazing, Ceiling (Roof), Walls, Floor among others, are vulnerable in that descending order with the most notable ones, Exterior Glazing and Ceiling, calling for special attention. The paper therefore concludes by offering useful suggestions to address issues related to the most vulnerable elements so identified, with a view to improving the interior living spaces in the study area.
