Abstract
This study examined the relationships between outdoor and indoor temperature characteristics in Yenagoa, Bayelsa State, Nigeria. It adopted the quasi experimental research design; as such data on meteorological parameters, such as, outdoor and indoor temperature were collected using thermometer and hygrometer, by the researcher in the study area and at designated locations in the metropolis, baring land-use in mind. The effective temperature equation was thereafter used to determine the effectiveness of the indoor temperatures, while the Pearson’s product moment correlation coefficient was used to determine the relationships between the outdoor and indoor temperature characteristics. Results indicate that the relationships between indoor and outdoor temperatures were not positive all year round. At the dry periods, outdoor temperatures showed strong correlation with that of indoor at p<0.05, but at rainy season temperatures outdoor showed weak association with indoor temperature at p>0.05. This implies that the relationships between indoor and outdoor temperatures are, to a good extent, dependent on seasons. There is, therefore, the need to design buildings based on climate. Yenagoa being a typical humid tropical area, more windows are recommended for buildings in it to help improve ventilation, and by extension, physiological comfort. Key words: Outdoor, indoor, effective-temperature, Yenagoa.
Highlights
Buildings are designed among other things to give shelter, comfort and security of life and properties to the occupants and or the owners of them (Cheng et al, 2012; Ojeh, 2011; Oluwafemi et al, 2010; Uzuegbunam et al, 2012; Abotutu and Ojeh, 2013)
The relationship between the indoor and outdoor temperature for the whole period of investigation shows that there is generally significant relationships between the indoor and outdoor temperature characteristics in the area at p
This is misleading, considering what happened in the wet period where all the correlation values for the indoor and outdoor temperatures in the land-uses were generally low and did not reach significance at p
Summary
Buildings are designed among other things to give shelter, comfort and security of life and properties to the occupants and or the owners of them (Cheng et al, 2012; Ojeh, 2011; Oluwafemi et al, 2010; Uzuegbunam et al, 2012; Abotutu and Ojeh, 2013). As a result of the dangers that could emanate from poorly planned building structure, architects and builders in the developed world give adequate attention to the aesthetics of a building, and to the capacity of such building to give comfort through proper ventilation, positioning (that is paying attention to the windward direction and the sun ray direction) (Uzuegbunam et al, 2012). All these are done to guarantee optimal comfort for inhabitants of buildings (Abotutu and Ojeh, 2013)
