Abstract

Heating, ventilation, and air conditioning (HVAC) systems are critical components in maintaining indoor environmental quality and energy efficiency in commercial buildings. Traditional HVAC systems often operate uniformly, without accounting for the diverse occupancy patterns and thermal requirements of different zones within a building. HVAC zoning control systems offer a solution by allowing for the independent control of temperature and air quality in different areas. This paper examines the impact of HVAC zoning control systems on energy consumption and indoor air quality (IAQ) in commercial buildings. By analyzing case studies, experimental data, and simulation models, this study identifies key benefits and potential drawbacks of zoning control systems. Results indicate that zoning control can significantly reduce energy consumption by up to 30% compared to traditional systems, primarily through optimized heating and cooling distribution. Moreover, zoning control systems enhance IAQ by reducing the incidence of over-conditioning and improving the management of pollutants and humidity levels. However, the implementation of such systems requires careful consideration of initial costs, maintenance, and potential disruptions to existing infrastructure. The findings underscore the importance of advanced control strategies and proper system design in maximizing the benefits of HVAC zoning in commercial buildings.
