Integrating EAHX and ventilation systems through a decision-making algorithm for enhanced energy efficiency and thermal comfort in smart buildings

Abstract

This research introduces a novel decision-making algorithm designed to optimize the use of Earth-to-Air Heat Exchangers (EAHX) and ventilation in buildings, aiming to improve thermal comfort and reduce the reliance on conventional Heating, Ventilation and Air Conditioning (HVAC) systems. Through comprehensive simulation-based method, the study evaluates the algorithm’s effectiveness in various seasonal conditions. It highlights the effectiveness of the ’Combined’ scenario, integrating EAHX and ventilation, which reduces energy consumption for heating and cooling by 14% and 16%, respectively. The findings also reveal notable seasonal variations in thermal comfort, with the integrated approach demonstrating enhanced performance in both summer and winter. This study underscores the potential of combining EAHX and ventilation systems in sustainable building practices, providing tailored solutions that address specific climatic and architectural conditions. The results contribute to advancing energy-efficient and environmentally conscious building design, marking a step forward in the pursuit of sustainable construction in an era of increasing environmental challenges.
