With the growing global demand for energy, significant concerns are also growing because of its environmental impacts. The process of production and consumption of energy itself has harmful effects on the environment. Buildings are one of the major contributors to energy consumption in the modern world. The Heating, Ventilation, and Air Conditioning (HVAC) system accounts for most of the building’s energy consumption and is important for providing a comfortable indoor environment for its users. However, HVAC systems contribute significantly to GHG (Green House Gas) emissions and global warming. Due to heavy reliance on mechanical systems, energy consumption increases. Hybrid Ventilation (HV) system can be one of the solutions to this problem. Hybrid ventilation (HV) strategies integrate both natural and mechanical ventilation strategies. These strategies reduce energy consumption by using natural and/or mechanical ventilation systems as per demand and utilize sensors to measure indoor air temperature, carbon dioxide levels, humidity, and outdoor conditions. While saving energy and improving energy efficiency, these systems also contribute to better indoor air quality by increasing fresh air intake. Better IAQ provides a healthy indoor environment for the building occupants. Also, HV systems are adaptable to different needs according to different climates as well as building types. This paper aims to explore the effectiveness of hybrid ventilation strategies in decreasing energy consumption and improving the energy efficiency of buildings via qualitative analysis and case studies.
Keywords: Hybrid ventilation (HV), energy efficiency, HVAC systems, fresh air intake, indoor air quality (IAQ)
