A simulation study for a low carbon consumption HVAC project using EnergyPlus

This paper presents how to use EnergyPlus to model a complex building by describing in detail EnergyPlus input parameters of a designing factory. It reports energy consumption, energy operation cost and environment impact of a heating, ventilation and air conditioning (HVAC) system used for space cooling and space heating in the factory. In this study, the HVAC system (System 1), a system with a nature gas boiler for space heating and a chiller for space cooling, is simulated using EnergyPlus. Moreover, the above-mentioned three indicators are calculated for HVAC System 2, the ground source heat pump system, based on the simulation results of System 1, and the annual economic and environmental benefits of the two systems were compared.
