Due to limitation of natural resources and negative effects of burning fossil fuel, energy efficiency associated with its consumption has become one of the biggest issue today. After getting inspired by the fact that more than 40% of global energy is consumed by buildings, building energy efficiency has become a subject of this research study. This project reviews various types of Heating, Ventilation, and Air-Conditioning (HVAC) system that is currently available in building designs. For a typical large office building, the Environmental Research Building at Boise State University was selected and modeled by the Sketch up; the building was approximately scaled to the actual size. The Open studio and Energy plus were used to run simulations with multiple HVAC systems and weather condition in Boise in order to compare energy consumptions and corresponding efficiencies. All the simulations were over a year period and 5th floor office was randomly selected to monitor the efficiency of applied HVAC system; mean temperature and humidity were measured. The simulated HVAC system includes, but not limited to Packaged Terminal Air conditioner (PTAC), Ground Source Heat Pump (GSHP), Natural Ventilation, Electric Furnace and Gas Furnace.
