Introduction
• The cooling performance of a building refers to its ability to
effectively provide cooling and maintain comfortable indoor
conditions during hot weather. It involves several factors that
influence the overall cooling efficiency and effectiveness of the
building's cooling system.
• The performance of these cooling systems directly impacts
energy consumption, occupant satisfaction, and overall building
efficiency.
• Inefficient cooling system account for about 40% of energy use
in commercial buildings and 60% in residential buildings.(US
Department of Energy, 2015). Hence there is a need for us to
study the performance of the cooling system and to take
necessary actions to minimize the energy consumption.

4. Technology towards
• The existing cooling system has several drawbacks such as
high energy consumption, maintenance challenges and
environmental impacts.
• Thus, to address to the above mentioned drawbacks it is
essential for us to assess the cooling performance of the
cooling system.

The challenges that we are likely to face when doing this project
are :
1.Data availability: Accurate and comprehensive weather data is
not easily available.
2.Limited features of Simulation software
3.System Interactions: Cooling systems often interact with other
systems or environmental factors. Accounting for these
interactions and their impact on cooling performance analysis
can be challenging.
