ABSTRACT:This study develops a computer application in Visual Basic computer programming language capable of computing the sensible and latent cooling loads of a single zone of a non-residential building taking all the influential factors into consideration, using the CLTD/SCL/CLF method.The developed program is enhanced with a special Graphical User Interface (GUI) to make it more User friendly. Basic equations relating to the problem were presented, these are mainly assumptions proposed by ASHRAE for its calculation of heat gain and cooling load.The calculation was based on the atmospheric condition and parameters obtainable in the month of March at 8hours interval between the 8.00hrs and 16.00hrs of the day. This space cooling load calculation was carried out for an actual building in University of Nigeria Nsukka (i.e. 3rd year lecture room in Mechanical Engineering Department) using the developed program and the maximum space loads which are required for the space are 11432 watts sensible and 4120 watts latent.
