HARC ON AIR

The development of technology for controlling outdoor air in the Asia-Pacific region is crucial in responding to the climate and lifestyle behaviors of people in the area, especially in terms of temperature, humidity, and air quality levels, which can impact the health and well-being of the population. Through research and advanced technology, it is possible to create an air control system that effectively addresses the needs of life in this region, whether it is reducing pollution from dust, pathogens, or bacteria, or improving air quality to be more health-friendly, particularly in terms of controlling temperature and humidity. This is especially relevant when connected to the behaviors of users in areas with diverse climates and specific usage needs. In Thailand, the development of technology that addresses the climate and lifestyle behaviors of the population is critical, as the levels of PM2.5 in many areas often exceed the World Health Organization (WHO) safety standards, leading to health issues such as respiratory and heart diseases. The development of technology that can reduce pollution from dust, pathogens, and carbon in the air by up to 90% and reduce carbon emissions by 25% will help improve air quality and promote health in the region, while also addressing the specific behaviors and needs of life in areas with different climates and pollution problems.

Pure Air for a Healthier Life: Are We Giving It Enough Attention?

Nowadays, we pay increasing attention to healthy eating, exercise, and mental well-being. But one crucial factor often overlooked is the quality of the air we breathe every single day.

Clean air isn’t just about protecting our lungs—it directly affects our energy levels, concentration, and overall well-being. Those who live in environments with fresh, clean air tend to feel more refreshed, less stressed, and healthier compared to those constantly exposed to polluted air.

How Does Clean Air Improve Our Well-Being?

1. Reduces the Risk of Respiratory Diseases
   Airborne pollutants like fine particulate matter (PM2.5) can penetrate deep into the lungs and even enter the bloodstream, increasing the risk of chronic respiratory diseases, allergies, and even cardiovascular conditions.
2. Enhances Brain Function and Productivity
   Proper oxygen levels improve focus, reduce fatigue, and boost cognitive function, making us feel more energized and productive.
3. Supports Emotional and Mental Balance
   Clean air is linked to increased serotonin levels, which contribute to improved mood, reduced stress, and an overall sense of relaxation. In contrast, exposure to air pollution has been linked to higher risks of depression and anxiety.

How Can We Improve the Air Quality Around Us?

There are two main approaches to enhancing air quality: Active solutions that use technology and Passive solutions that rely on nature and thoughtful design.

Active Solutions: Leveraging Technology for Cleaner Air

• HEPA Filters & Air Purifiers – These capture fine dust particles, pollen, and other pollutants, preventing them from entering our lungs.
• Energy Recovery Ventilation (ERV) Systems – These exchange stale indoor air with fresh outdoor air while minimizing energy loss and controlling humidity.
• UV-C Air Disinfection – This technology uses ultraviolet light to neutralize airborne bacteria and viruses, improving air hygiene.
• Electrostatic Precipitators (ESP) – Devices that use electrical charges to trap fine dust and pollutants from the air.
• Air Ionization – Releases negative ions to attract dust and toxic gases, making them easier to filter out.

Passive Solutions: Harnessing Nature and Smart Design

• Green Walls & Urban Trees – Plants act as natural air filters, absorbing CO₂ and trapping dust particles. A well-placed tree can significantly improve air quality in urban areas.
• Permeable Pavements – These surfaces help reduce dust accumulation by absorbing rainwater and preventing pollution from lingering in the air.
• Wind Corridor Design – Thoughtful urban planning can allow natural airflow to flush out stagnant, polluted air and replace it with fresh air.
• Photocatalytic Coatings – Special coatings on building surfaces help break down harmful pollutants like nitrogen oxides (NOx) and sulfur oxides (SOx) using sunlight.

How Cities and Communities Can Benefit from Cleaner Air

In highly polluted cities, integrating both active and passive strategies can dramatically improve urban air quality. Active systems are particularly effective in high-pollution zones, whereas passive methods can be implemented in urban planning and architectural design to create cleaner and healthier public spaces.

For example, a city with more green spaces, rooftop gardens, and air-purifying building facades will naturally have cleaner air than one dominated by concrete and heavy traffic. Similarly, encouraging businesses and households to adopt air filtration systems and smart ventilation can create a collective impact on air quality at the local level.

Small Actions, Big Impact: What Can We Do?

Improving air quality doesn’t always require large-scale policy changes. Small daily actions can contribute to a healthier living environment:

• Improve indoor air circulation by opening windows whenever possible (as long as outdoor air quality is good).
• Surround your home with plants that help purify the air, such as snake plants, peace lilies, or ferns.
• Use non-toxic household products to reduce indoor air pollution caused by synthetic chemicals.
• Avoid excessive vehicle use and opt for public transportation, biking, or walking when feasible to reduce emissions.

Breathing Easy for a Healthier Future

At the end of the day, good health is not only about what we eat but also about the air we breathe every second. By making conscious efforts to improve air quality—whether through technology, nature, or everyday choices—we can create an environment where wellness truly begins with every breath.

ERV Technology: Development and Role in the Era of Sustainable Buildings

A HARC-ONAIR Innovation Focused on IoT, Wellness, and Recycled Materials

The modern approach to architectural design and development is shifting toward sustainability, both in terms of energy efficiency and occupant well-being. One of the key innovations supporting this movement is Energy Recovery Ventilation (ERV) technology. ERV plays a crucial role in maintaining indoor air quality while simultaneously optimizing energy consumption by recovering thermal energy from exhaust air. As sustainable building strategies become increasingly vital worldwide, ERV systems are gaining widespread adoption across various architectural applications.

How ERV Technology Works

ERV systems function by exchanging heat and humidity between incoming fresh air and outgoing exhaust air. During hot seasons, the system recovers cool energy from the indoor air before it is expelled and uses it to pre-condition the incoming warm air. This reduces the workload on the air conditioning system. Conversely, in colder months, ERV captures heat from the outgoing indoor air and transfers it to the incoming cold air, thereby reducing the energy required for heating. This process significantly enhances energy efficiency while maintaining a comfortable indoor climate.

Innovations in ERV Technology

Continuous advancements in ERV technology have led to increased energy recovery efficiency, making it adaptable to diverse climate conditions. Some key innovations include:

• High-Performance Heat Exchangers: Modern ERV systems incorporate advanced materials like ceramic or aluminum cores that enhance energy retention and transfer efficiency.
• Smart Sensors and AI-Driven Control Systems: The integration of IoT technology allows ERV systems to adapt to real-time environmental conditions, optimizing energy recovery based on occupancy levels and air quality.
• Sustainable Design and Recycled Materials: As part of the broader green building movement, newer ERV units incorporate eco-friendly materials, further reducing their environmental footprint.

Integration of ERV in Modern Sustainable Architecture

With the increasing emphasis on low-energy buildings and health-centric design, ERV has become an integral component in contemporary architectural planning. From office buildings and residential complexes to hospitals and educational institutions, ERV technology helps maintain superior indoor air quality while reducing overall energy consumption. Moreover, the deployment of ERV systems supports carbon footprint reduction, aligning with global sustainability goals.

Key Advantages of ERV Technology

1. High Energy Recovery Efficiency: ERV systems can recover up to 70-90% of energy, significantly lowering heating and cooling costs.
2. Improved Indoor Air Quality: The ability to regulate temperature and humidity ensures a fresher, healthier indoor environment.
3. Sustainability and Carbon Reduction: By minimizing energy use and reducing greenhouse gas emissions, ERV contributes to long-term environmental sustainability.

Conclusion

ERV technology is more than just an energy-saving solution—it is a vital component of future-ready, sustainable buildings. As material science and intelligent control systems continue to evolve, ERV will remain at the forefront of eco-conscious architectural design, enhancing both energy efficiency and occupant well-being.
