The key objective of this work is to maintain the pre-determined inside conditions & to establish thermal equilibrium the prime rate at which heat needs to be detached from the space. Nowadays one of the most serious problems is environmental issues. For this problem, energy utilization by buildings and enterprises are responsible. Markets, Residential houses, commercial buildings, industry, and Infrastructure consume approximately 72% of the world’s energy. Roughly 60 % of a building’s total energy necessity is distributed to the plant of air-conditioning installed in a big complex or building that is air acclimatized. To limit energy utilization, accurate prediction of the cooling load are important. The elementary heat transfer concepts are used to manually calculate the cooling load of a multi-storey building. This method is derived from CLTD technique of cooling load estimation. We estimate the cooling load at the extreme conditions. So, we have taken the outside conditions as relative humidity 54% and 450C DBT for the month of May during summer. The average outside air velocity during this period is 1.67 m/s. The significance of this work is to show that, actual cooling load prediction results in less capital cost, investment and energy consumed. Thus, accuracy should be paramount when load calculation is being performed.
