In an era where climate change, energy consumption, and public health intersect, the way we design, operate, and innovate within our buildings has never been more critical. At the heart of this transformation lies the HVAC (Heating, Ventilation, and Air Conditioning) system.


Although typically hidden from sight, HVAC infrastructure plays a crucial role in energy use, indoor air quality (IAQ), and carbon emissions. A closer look reveals that HVAC systems profoundly impact a building’s functionality, environmental footprint, public health outcomes, and operational efficiency.

The Energy-Intensive Reality of HVAC Systems

HVAC systems are among the largest energy consumers in residential and commercial buildings, often responsible for a significant portion of a building’s operating costs and environmental footprint. In the United States alone, HVAC accounts for approximately 35% of a building's energy consumption, a figure that can be even higher in colder and warmer climates due to increased heating and cooling demands. According to the 2021 Global Status Report for Buildings and Construction by the GlobalABC, the buildings sector accounted for 36% of global final energy consumption and 37% of energy-related CO₂ emissions in 2020.


Historically, HVAC systems have been energy-intensive by nature, using vast amounts of power to regulate temperature and maintain air quality within a building. This often places HVAC at the center of energy-saving and decarbonization initiatives. However, balancing energy efficiency with effective indoor air quality control has proven challenging.


Ventilation, which is essential for good IAQ, typically requires large volumes of air to be exchanged, a process that consumes significant energy and raises costs. This trade-off between energy savings and IAQ improvement has long hindered the HVAC industry’s transition to sustainable practices.


The Cost of Compromised Indoor Air Quality

Indoor air quality plays a vital role in health, well-being, and productivity. Poor IAQ has been linked to respiratory diseases, allergies, and even mental fatigue, while the economic cost of inadequate IAQ often goes unmeasured. The World Health Organization estimates that air pollution contributes to more than 4 million premature deaths each year, with indoor air pollution being a significant factor. Studies indicate that improved IAQ can reduce health risks and enhance cognitive function, particularly in office and educational settings where individuals spend extended hours indoors.


A study by the Harvard T.H. Chan School of Public Health found that participants in green office environments experienced a 61% improvement in cognitive scores, while those in green+ environments with enhanced ventilation saw scores double compared to conventional settings, underscoring the link between IAQ and productivity. Improved indoor air quality also reduces absenteeism, as shown by a U.S. Environmental Protection Agency (EPA) study reporting a 10% decrease in student absences with better IAQ, and additional research indicating that increased office ventilation can reduce short-term employee absences by 35%. These findings emphasize the importance of maintaining optimal IAQ in both educational and professional settings for health and productivity.

HEPA Filters: Capturing the Tiniest of Particles

High-Efficiency Particulate Air (HEPA) filters are considered the gold standard in air purification. These filters are designed to trap and capture 99.97% of particles as small as 0.3 microns. To put that into perspective, a human hair is about 50-70 microns thick!


HEPA filters work by using a dense mat of fibres that create a labyrinth-like barrier for the air to pass through. As air flows through the filter, the fibres trap particles such as dust, pollen, pet dander, mold spores, and even some bacteria and viruses. By removing these particles from the air, HEPA filters help improve indoor air quality and reduce the risk of allergies and respiratory problems.


Activated Carbon Filters: Eliminating Odours and Chemicals

Activated carbon filters are highly effective in removing odours, gases, and volatile organic compounds (VOCs) from the air. These filters are made from charcoal that has been treated to create a vast network of pores, which increases its surface area.


When air passes through the activated carbon filter, the pores absorb and trap the odours and chemicals. This process is known as adsorption, where the particles adhere to the surface of the carbon. By removing unpleasant smells and harmful chemicals, activated carbon filters contribute to a healthier and more pleasant indoor environment.


UV-C Sterilization: Disrupting the DNA of Microorganisms

UV-C sterilization is a technology that uses ultraviolet light to kill or inactivate microorganisms such as viruses, bacteria, and mold spores. UV-C light has a wavelength range of 200 to 280 nanometers, which is harmful to these microorganisms.


In air purifiers, UV-C lamps are typically placed near the filters or inside the air ducts. As air passes through, the UV-C light irradiates the microorganisms, disrupting their DNA or RNA, and rendering them unable to reproduce or cause harm.


While UV-C sterilization is effective against certain pathogens, it is important to note that it mainly targets microorganisms suspended in the air and may not be as effective against settled particles or larger organisms.


Combining Technologies for Maximum Efficiency

Indoor air purifiers often combine multiple filtration technologies to maximize their efficiency. For example, a purifier may use a pre-filter to capture larger particles, followed by a HEPA filter to remove finer particles, and finally, an activated carbon filter to eliminate odours and chemicals.

By utilizing different technologies, air purifiers can provide comprehensive air filtration, addressing a wide range of contaminants and improving indoor air quality.


The world of indoor air filtration is vast and ever-evolving. HEPA filters, activated carbon filters, and UV-C sterilization are just a few of the technologies used in air purifiers to ensure clean and fresh indoor air.
