Recognizing Poor Indoor Air Quality Menace with the Onset of Summers

This content has been authored by Varun Pahwa, President, Desiccant Rotors International (DRI)

With low pangs of summers already being felt, people will be more prone to spend time indoors to beat the heat outside. There will be many who will be taking a sigh of relief thinking that now they will be free from the poor Indoor Air Quality (IAQ) menace prevalent during winters. But in reality, the issue of poor IAQ is a persistent issue all-round the year. It only gets worsened in summers with centralized air conditioning systems in the enclosed spaces that leave no space for the influx of fresh air and only stale air keeps circulating in the building.

The impact is felt even more starkly in industries like healthcare, construction, factories, hotels, airports, given to their packed, and complex structure that deteriorates the air quality within the premises. Moreover, these places often being huddled with large crowds compounds the problem.

As a result, there have been rising instances of ‘Sick Building Syndrome’ which is a serious threat to the health and overall wellbeing of the person. Additionally, the poor IAQ is also responsible for a wide range of issues like breathing problems, lethargy, pain in the eyes, and other long-term illnesses.

In order to arrest the issue, people need to be aware that the indoor air can easily get influenced by the outdoor air and is 10 times worse and more harmful because of restricted airflow in the enclosed area. It is not just the metropolitan cities that get affected but even the surrounding cities face the menace of poor indoor air quality.

Hence, highly efficient building management systems must be installed in centrally conditioned spaces such as office complexes, homes, malls, hotels, restaurants, auditoriums, and various other closed premises to not just deal with the contaminants/pollutants generated indoors but ensure that outdoor pollution like PM 2.5, PM10, VOCs as well other gaseous contaminants are not brought inside enclosed spaces through conditioning systems.

Understanding that the major cause of poor IAQ is the lack of clean fresh air in the buildings which only worsens with the presence of moisture, ensuring proper ventilation is the best solution to improve indoor air pollution. It dilutes the contaminated air indoors by utilizing the fresh air from outside. With the help of this approach, one can thoroughly clean the outside fresh air and introduce it into the building, maintaining positive pressure inside the building.

Here, HVAC&R systems are highly efficient in ensuring proper ventilation and are backed up with a wide range of advantages. It not just renders acceptable indoor air quality but also provides thermal comfort in the enclosed space. The system employs advanced desiccant technology that uses hygroscopic substances to suck moisture from the air in order to maintain the proper RH and cool down the indoor spaces. One of the primary benefits of this technology is that it tones down the air according to the requirement of the given space. The Energy Recovery systems ventilate the conditioned spaces without compromising on air conditioning load. Owing to this mechanism there is substantial reduction in the use of energy and utility costs.

Along with HVAC&R system installation, people must also be agile enough to adopt green building designs. Green Building Councils across the globe are playing a critical role in promoting awareness and certifying the importance of Indoor Air Quality in our day-to-day lives. The advanced buildings help in striking the right balance in the indoor air quality that does not compromise on the comfort of the people but at the same time coherently contribute to reducing the energy consumption of the building with the help of green products. These buildings are the most viable solution as it highly maintains proper relative humidity (RH) and prevents any growth of mold, mildew in the enclosed atmosphere.

With advanced systems in place and efficient air purifying systems, maintaining good indoor air quality, even in large spaces has become a cost-effective and doable affair.

To Make Workplaces Healthy & Safe, Building Intelligence Firm 75F Launches "Epidemic Mode" HVAC Software Sequences

As offices prepare to reopen across India, buildings are the new front in the fight against COVID-19. Yesterday, the building intelligence company, 75F, has announced 75F Epidemic Mode^TM, a new HVAC software sequence that ensure commercial buildings are healthier while keeping employees and customers safe. The system features various components such as indoor air flushes, where post working hours the entire air within the premises is replaced with fresh air from outside and during office hours ventilation from outside is increased to limit movement of airborne particles and reuse of indoor air. All these are based on the latest guidance from scientists, government organizations, and global industry leaders such as ISHRAE which has been adopted by the Indian Government, ASHRAE and the CDC.

Recent studies show the spread of COVID-19 appears to be occurring through airborne transmission of aerosols, particles 1-5 microns in size which cannot be reliably filtered out using a MERV-13 or HEPA filter. While much of the focus is on droplets 100-1000 microns in size produced by coughing or sneezing, a large quantity of aerosolized infectious particles are also produced, and are more likely to be produced by asymptomatic individuals or those who do not know they are infected simply from breathing or speaking. A recent study showed that more than 1000 of these virus-containing aerosols are emitted every minute of speaking, more proof that without dilution ventilation from outside air, buildings have a high risk of viral build-up and exposure. 

In response to this, various organisations such as ISHRAE (Indian Society of Heating, Refrigerating and Air-conditioning Engineers), ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers) and the CDC (Centre for Disease Control) have released new guidelines for the operation and control of HVAC systems to reduce disease transmission from infectious airborne particles and ensure a safe and healthy workplace. 

The 75F Epidemic ModeTM achieves the directives through its specific application profiles; Smart PurgeTM and Smart Enhance VentilationTM.

75F Smart Purge^TM

75F’s Smart Purge™ application profile works in pre- and post-occupancy settings and fully adheres to ISHRAE, ASHRAE recommendations to prevent re-circulation of air and to purge the air before and after occupancy. 

75F Smart Enhanced Ventilation^TM

This profile ensures the indoor environment remains as safe as possible during a building’s occupied period and reduces risk of infection from aerosolized particle.

Apart from minimizing viral loads in buildings the 75F Epidemic ModeTM also delivers significant energy savings. Increasing ventilation from 20% outside air to 90% outside air can normally lead to a high energy bill, but with the 75F Epidemic Mode profiles, concentration of infectious airborne particles is reduced while energy consumption is minimized.

“The world is in the midst of a pandemic with so many unknowns, where the brightest minds are developing innovative ways to modify their businesses and 75F Epidemic Mode does that for the commercial building industry,” said Deepinder Singh, CEO and Founder of 75F. 

“Being able to give companies and their employees some peace of mind that their facilities managers are taking the initiative to make their environments safe and healthy is extremely important and we believe will become the norm even when the outbreak is over”, adds Gaurav Burman, APAC President of 75F.

Epidemic ModeTM is updated by 75F as guidelines from these organisations evolve or new data emerges. This means it offers the most current sequences that minimize operating expense and viral transmission, while improving indoor air quality (IAQ) and energy efficiency. Furthermore, 75F Epidemic ModeTM does not require any manual programming and there is no risk of equipment damage from running the system outside typical parameters.

Apart from minimizing operating expense the 75F Epidemic ModeTM also delivers significant energy savings. Increasing ventilation from 20% outside air to 90% outside air can normally lead to a high energy bill, but with the 75F Epidemic Mode profiles, concentration of infectious airborne particles is reduced while energy consumption is minimized. 

75F offers the only system on the market today currently implementing these healthy buildings measures, which are available free of charge to all customers in office buildings, retail businesses, schools, restaurants, and apartment buildings. Once the pandemic is controlled, 75F technology will allow facility managers to easily, and remotely, disable these measures, with a return to 75F's award-winning algorithms to improve the comfort of occupants.
