The application of solar thermal systems in the residential sector has been one of the most efficient solutions to energy shortage issues experienced globally. Since the need for well thermally conditioned buildings is rising, highly efficient renewable energy systems are crucial in meeting space conditioning energy demand in residential buildings. This study analyses the performance of a proposed novel hybrid solar-biodiesel thermal energy system for space heating and cooling, for a typical family residential building in Cyprus. The proposed system which integrates evacuated tube solar collectors, thermal energy storage tank, Li-Br absorption chiller and a biodiesel boiler is modelled using TRNSYS. The space conditioning energy demand of a typical family house in Cyprus were obtained through a survey. The 10.5kW proposed system demonstrated a performance capability by satisfying 37800kJ/h of space conditioning energy demand. Thermal energy from solar managed to meet 100% and 87.7% of the cooling and heating energy demand respectively and biodiesel satisfied the heating energy deficiency. The cost analysis reflected a payback period of 7 years and total savings of $37900 over 25 years, highlighting the energy and cost effectiveness of renewable energy thermal systems in residential buildings.
