The objective of this work is to estimate the HVAC energy consumption of an educational building using different air conditioning systems. The building is located in Meshref area, in Kuwait. The cooling load as well as light and electric appliances load of the building are estimated using Hourly Analysis Program (HAP). Three different HVAC systems were investigated in this work, namely, “Packaged DX Fan-Coil Rooftop”, “Variable Air Volume - Single Fan - Dual Duct” (VAV) and a Rooftop Variable Refrigerant Flow with Dedicated Outdoor Air System (VRF). Results showed that the energy bill when using VRF is 33% less than that of VAV, and 27% less than that of the PKG type. Although the capital cost of the VRF is higher than that of the other HVAC systems, but it is higher energy efficiency can pay for that in a short time.

Keywords : Cooling Load, Variable Refrigerant Volume (VRV), Variable Refrigerant Flow (VRF), Hourly Analysis Program (HAP).
