Effect of Climate Change on Outside Air Design Temperature for Air Conditioning Cooling Load Calculations For Ikeja and Ilorin, Nigeria

Abstract

ABSTRACT Hourly dry-bulb temperatures for Ikeja and Ilorin were obtained from the Nigerian Metrological Services Agency, Oshodi, Lagos, for the years 1995-2008. Statistical analyses were carried out on the data to obtain the average hourly temperatures for each month, the average temperature for each month, and the average temperature for the four warmest months (along with the standard deviations for each case). The average hourly temperatures were compared with those obtained by Ariyo for the two locations for the year 1978-1992. The 1%, 2½%, and 5% design temperatures obtained from the average temperature for the four warmest months, assuming the temperature distribution follows a normal distribution pattern, were also compared with those obtained by Ariyo for 1978-1992, as well as with those obtained by Shoboyejo and Shonubi for 1951-1965. It was observed that the average hourly temperatures were higher in the Shoboyejo-Shonubi work than those obtained by Ariyo for all the months for both locations. T...
