SUSTAINABLE ARCHITECTURE AND THE IMPACT OF SMART VENTILATION, AIR CONDITIONING, AND HEATING (VACH) SYSTEMS

The advent of Smart Ventilation, Air Conditioning, and Heating (VACH) systems has markedly transformed sustainable architecture by improving energy efficiency, indoor environmental quality (IAQ), and occupant comfort. This paper underscores the critical role of Smart VACH systems as foundational elements in sustainable building design, promoting energy conservation and environmental stewardship within the built environment. Methodologically, a comprehensive literature review is adopted to examine how Smart VACH systems contribute to sustainability objectives in architectural design. Through a detailed analysis of performance metrics and environmental impacts, the study compares intelligent VACH systems to conventional alternatives, highlighting their superior contributions to energy conservation, reduced carbon emissions, and overall sustainability. Findings indicate that Smart VACH systems not only enhance indoor air quality but also substantially reduce operational costs and extend equipment lifespan, thus lowering maintenance requirements. Moreover, these systems improve occupant health and productivity by maintaining consistent indoor air quality and thermal comfort, factors shown to enhance well-being in built environments. This paper concludes by discussing the limitations of current research and suggests potential areas for further exploration, advocating for wider adoption of Smart VACH systems across diverse architectural settings to strengthen sustainable building practices.
