Abstract: Poultry sheds are used to raise poultries (chickens, turkeys and ducks), and have a unique heating and cooling demand pattern. A significant amount of energy is consumed for the heating and cooling of poultry sheds to maintain an indoor air temperature suitable for the growth and comfort of the poultries according to their age. This energy consumption results in a considerably high greenhouse gas (GHG) emissions and energy expenditure for the poultry shed operation. Previous studies have shown that a large amount of operational and lifecycle cost of heating can be reduced with the adoption of hybrid geothermal-solar-gas systems. In addition to the costs, GHG emissions should also be considered when heating equipment is selected. This paper presents an environmental analysis and optimisation for the sizing of components of a hybrid geothermal-solar-gas system for a typical poultry shed located in Peats Ridge, NSW, Australia. The results reveal that up to 100% of the operational emissions and up to 95% of the lifecycle GHG emissions can be reduced if the current gas heating system is replaced by the hybrid geothermal-solar-gas system. By also considering the lifecycle cost, the Pareto front solutions for this hybrid geothermal-solar-gas heating system has been found.
