Development of a country will lead to increased utilization and demand for energy. In this research study, transient simulation technique is implemented and eventually, the cooling load of the house is determined. The study focused to provide cooling load characteristics for a residential house. The factors namely: size and shape, thermophysical properties, window systems, orientation, internal gains, ventilation and infiltration aspects that influence the cooling load are considered in the study. A dynamic simulation software-TRNSYS (Transient Systems Simulation Program) is used for the modelling and simulation of the energy flows of the house to determine the cooling thermal load. The study is useful in providing a better solution for a sustainable future by simulating with different design modifications of the house. This study may be extended to focus on the choice of constructional materials, so that good temperature and lower cooling load are attained. A case study of a residential building is situated in the coastal district of Andhra Pradesh, India and located at Latitude (17.68o N) and longitude (83.21oE) is considered to find cooling load through TRNSYS 16.
