An archetype model of a typical Irish home was developed using DesignBuilder to simulate and evaluate the operational energy performance of systematic energy upgrades. The parameters under investigation include different heating systems (ASHP, GSHP, Boiler) with varying seasonal efficiencies, heating set-point temperature, and heat recovery technologies. The embodied carbon impacts of these actions were quantified using OneClickLCA, integrated with DesignBuilder for a thorough assessment. The simulation data was critically analysed offering actionable insights for stakeholders in environmental and sustainability engineering.

Several materials are readily available in hundreds of sizes and can withstand extreme pressures and temperatures, so they are key components across many industries including automotive, pharmaceutical, and aviation. This project investigates the ability to accurately model O-ring in-service behaviour through Finite Element Analysis (FEA). ANSYSWorkbench was used to subject realistic loading conditions on simple O-ring seals to study the resulting deformation and stresses. Both axisymmetric and 3D analyses were simulated to determine the most suitable method. The results were then validated against existing results in literature tomake a judgement on the accuracy of the model.
