Abstract

Energy studies were performed on a multi-purpose building as part of net-zero energy consumption study for the building. With limited world energy supply, the incentive and necessity has grown for net-zero energy (zero net energy consumption) buildings or buildings close to net-zero where energy is utilized efficiently and also harvested on-site. Measured data of actual energy utilization by the building for a continuous period of over 30 months were collected and studied. The U.S. Department of Energy (DOE) EnergyPlus software was used to simulate energy requirements for the building. Alternative energy sources such as ground source heat pump, solar photovoltaic (PV) electric energy generation and day-lighting modifications were applied to redesign the energy requirements for the building towards meeting net-zero energy utilization. Results show that it is possible to achieve the aim of net-zero energy supply for the building. The results also show significant reduction in energy use for the building with the net-zero design as well as the extents of the contributions of the individual energy reduction measures. The directions to proceed towards achieving complete net-zero energy status for the building were identified.
