Indoor Air Quality
The World Health Organization (WHO) estimates that air pollution causes approximately seven million premature deaths each year globally. A World Bank study estimated that the global cost of premature deaths due to air pollution is about $5.7 trillion annually, equivalent to 4.8% of the global GDP.
Indoor air quality can be three to five times more polluted than outdoor air quality. In the Middle East, where individuals spend around 90% of their time indoors due to extreme weather, indoor air quality is a significant concern.
Children are especially vulnerable to poor air quality, which can have substantial short-term and long-term health impacts. Exposure to poor air quality in early childhood increases the risk of chronic diseases later in life, such as cardiovascular diseases, respiratory disorders, and certain types of cancer.
Poor indoor air quality directly affects the health, wellness, and cognitive abilities of residents, leading to:
- Respiratory Issues: High levels of air pollution increase the risk of respiratory problems like asthma, bronchitis, and other infections. Poor air quality can worsen existing respiratory conditions, resulting in more frequent symptoms, hospitalizations, and medication use.
- Reduced Lung Development: Childhood exposure to air pollution can impair lung development, leading to reduced lung function and capacity, and long-term respiratory problems.
- Increased Risk of Allergies: Poor air quality, including allergens and particulate matter, can trigger allergies in children, such as hay fever and eczema, affecting sleep and daily activities.
- Cognitive and Neurological Effects: Research shows a link between air pollution and cognitive and neurological effects in children, including decreased cognitive function, impaired memory, attention deficits, and reduced academic performance.
Building Health, Saving Energy
By Samiullah Khan, CEO, SAIF AIR Technologies
Samiullah Khan, CEO of SAIF AIR Technologies, highlights that HVAC systems account for about 70% of a standard building’s electricity consumption in the region. The integration of AI and machine learning can predict ambient and indoor air quality, as demonstrated by HEECO2R installed in Hotel Treppan, Dubai.
The built environment contributes to approximately 17% of global greenhouse gas emissions. In the UAE, real estate industry emissions are the largest contributor to the national carbon footprint, estimated to be over 30% according to the Green Building Council.
Commitment to Decarbonisation
The UAE has set ambitious national decarbonisation targets. To combat climate change and transition to a sustainable future, the UAE aims to reduce carbon emissions by 50% by 2030, aligning with the Paris Agreement to limit global temperature rise to well below two degrees Celsius above pre-industrial levels.
The HEECO2R Process
The HEECO2R process, patented as WO2020255154A1 and promoted by SAIF AIR Technologies, enhances indoor air quality and reduces the carbon footprint by minimizing energy consumption. When installed according to prescribed standards, it captures CO2, VOCs, and humidity, facilitating a transition to a “Net Zero Carbon” approach.
The system, powered by renewable energy, controls air intake quality, quantity, and timing based on IAQ requirements, atmospheric air quality (AQI), and weather predictions. It also contributes to water and food security by using captured carbon in a greenhouse cooled by radiant cooling, or storing it for future use.
Sustainable Building
In tropical regions, cooling systems consume 70% of total energy. Achieving proper indoor air quality is challenging due to poor maintenance, aging equipment, and increasing electricity tariffs. HEECO2R reduces cooling energy consumption by 30-35%, decreasing overall energy consumption by 20%, making buildings more energy-efficient.
Profitable Retrofit
HEECO2R saves energy in cooling and dehumidification, with a payback period of 2-3 years. Savings in maintenance costs further enhance its attractiveness. This innovative technology can revolutionize the HVAC landscape in the UAE and globally, with high scalability for individual buildings or centralised air delivery systems like district cooling.
Case Study
At Hotel Treppan in the UAE, HEECO2R achieved approximately 30% savings in electricity bills and a 45% reduction in cooling system energy consumption over twelve months, maintaining indoor air quality within ASHRAE standards. The reduction in carbon footprint, equivalent to planting around 10,000 trees and repurposing 3,000,000 plastic bottles, demonstrates its effectiveness.
The system integrates seamlessly with chiller or district cooling systems for various applications, from individual villas to smart cities, offering benefits like enhanced indoor air quality, eradication of sick building syndrome, reduced maintenance costs, diminished heat island effect, improved HVAC redundancy, and substantial reductions in carbon footprint and electricity expenses.
