This review paper discusses the technological advancements and innovative strategies of heating, ventilation, and air conditioning (HVAC) systems for buildings. Buildings are a major contributor to energy consumption and greenhouse gas (GHG) emissions, representing about 35% of global final energy use and 26% of energy-related GHG emissions. In Canada, the building sector accounts for roughly 31% of energy demand and 18% of total GHG emissions, with HVAC systems responsible for 40–50% of this energy use. The current challenges, emerging trends, and future prospects for HVAC and related technologies are systematically reviewed to promote sustainability, affordability, and resilience in buildings. The literature scanning begins with an overview of the prevailing energy scenario in buildings, HVAC technologies, and other regulatory and policies.
The paper thoroughly examines the critical role of HVAC systems in reducing energy consumption, minimizing environmental impact, improving building affordability and enhancing occupant health and productivity. It discusses emergent technological opportunities, energy efficiency measures, sensors, smart controllers, Internet of Things (IoT) and AI-based technologies.
The paper highlights the barriers to adopting new technologies and strategies. It provides an evolving topography of HVAC technologies, their current state and emerging directions to tackle environmental challenges, including net zero energy and zero carbon building goals.
The review suggests that while there are promising advancements in HVAC technology, further research and practical demonstrations of innovative solutions are necessary to maintain the momentum in building modernization efforts. - Contributor
