Abstract

This study examines the impact of thermal insulation on thermal comfort and energy consumption in an existing house that did not comply with building regulations. Thermal insula-tion included adding layers of polystyrene in the ceiling and floor, the areas with the highest heat gain and loss. After renovation, findings demonstrated a 55% reduction in heating energy required for winter. Reduction in air conditioning power was 18% during the summer. Simulations using the DesignBuilder software for the house revealed a 42% and a 17% reduction in the energy needed for heating and cooling. TRNSYS software simulation indicated a 500 kWh average annual energy consumption reduction. Experimental results measurements in two days of summer proved that the indoor temperatures of the house did not exceed 25.1°C and remained stable regardless of changes in external temperatures. Thermal insulation is a promising solution for reducing energy consumption and achieving thermal comfort in buildings.
