Abstract: Heating ventilation and air conditioning (hvac) main goal is to provide thermal comfort and acceptable air quality inside rooms. In large buildings huge amount of energy is wasted due to its weak thermal performance and moderate hvac system. Heat load calculation is a basic step to be considered during designing a hvac system for a building. During heat load calculation weather conditions and occupants of a room are to be considered. Auditing is done on power consumption of a building when two different hvac system are used for distribution of conditioned air and also design a duct. In these paper fan coil unit and air handling unit are compared with each other and investigated how much power is consumed while using each system separately. When fan coil unit is connected with a duct the power consumed by a building is 32.75 kw/hr and when air handling unit is connected with a duct the power consumed is 41 kw/hr. Thus fan coil unit is preferred over air handling unit because it consumes less power and according to that duct is designed using designing tool to attain uniform cooling.
