What is PM 2.5?

PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair.

Commonly written as PM2.5, particles in this category are so small that they can only be detected with an electron microscope. They are even smaller than their counterparts PM10, which are particles that are 10 micrometres or less, and are also called fine particles. These fine particles can spread and travel to the respiratory system, blood current and absorbed in the system of the body function which can increase the possibility to have the chronic diseases.


Air Quality Index (AQI) Values in India

AQI updated the current situation of PM2.5 in India on November 20, 2019 as below detail

  • New Delhi US Embassy to read 270 AQI which is considered to be Very Unhealthy. Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
  • Lal Bahadur Shastri Nagar, Kalaburagi is the highest risk area by reach 824 AQI which is considered Hazardous. Everyone may experience more serious health effects at this 824 AQI. Everyone should avoid all outdoor exertion


  • Where does PM2.5 come from?

  • source of air pollution - power plant
  • Fine particles can come from various sources. They include power plants, motor vehicles, airplanes, residential wood burning, forest fires, agricultural burning, volcanic eruptions and dust storms.
  • Some are emitted directly into the air, while others are formed when gases and particles interact with one another in the atmosphere.
  • For instance, gaseous sulfur dioxide emitted from power plants or factories reacts with oxygen and water droplets in the air to form sulfuric acid as a secondary particle.
  • How can PM2.5 affect your health?

  • With the toxic elements that cause PM2.5, Fine particles, WHO has determined PM2.5 to be listed in the first group of element that causes Cancer. Ambient (outdoor) air pollution in both cities and rural areas was estimated to cause 4.2 million premature deaths worldwide per year in 2016; this mortality is due to exposure to small particulate matter of 2.5 microns or less in diameter (PM2.5), which cause cardiovascular and respiratory disease, and cancers.

    Harm from PM2.5

    1) Harmful to the lungs: it can lead to Pneumoconiosis

    2) Affect the health: difficult to breathe, eyes irritation, headache, dizzy, feel queasy, easily tired, asthma

    3) Affect the respiratory system: coughing, sneezing, running nose, irritated nose, sore throat, coughing with phlegm or it can affect the lower respiratory system: – chest pain, congested chest, cannot breathe properly.

    4) Harmful to the eyes: infectious eyes, irritated eyes, eyes allergy, and cataract

    5) Bronchitis, Acute and Chronic

    6) Harmful to the heart: heart diseases, cardiovascular disease

    7) Respiratory cancers

    8) Harmful to skin

    9) Harmful to some certain risky group of people who get asthma, allergy and lung cancer.

    10) Harmful to pregnant women

  • Are there ways to reduce your exposure to PM2.5? How to reduce PM2.5?

  • There are many ways to reduce your exposure to PM2.5 and it is very easy to do like these below methods

    1.Close all the windows and always clean the house
    2.Wear high quality N95 masks or P100 masks
    3.Avoid Outdoor activities like exercises

    However, air pollution from PM2.5 in India will come back again and again every year if we have been still doing every activity as same as nowadays. To solve this problem sustainably, you can be the one who reduce PM2.5 in India to atmosphere by doing like these.

  • How to prevent Air pollution PM2-5 in India

    1. Avoid using private cars, no garbage burning and no cigarette smoking
    2. Turn off the idling engines
    3. Checkup of the car conditions
    4. Stop outdoor burning
    5. Avoid burning of incenses
    6. Avoid cooking that uses charcoal
    7. Use the type of construction material which does not cause dust in the construction industry.

  • Construction industry always causes PM2.5 Fine particles therefore when selecting the construction material, you have to select the material which does not cause a large amount of dust. E.g. when you use bricks in the construction, you must use mortar for plastering.

  • When mixing the cement with water, sand and aggregates, it is likely that this process will cause dust in the air and atmosphere. But if you use the other materials like Fiber Cement Board or Gypsum Board to substitute the bricks, it will help reduce the dust or Fine Particles at a certain level. Because Fiber cement board and Gypsum Board do not need to be plastered after installation. Painting is needed only. The installation of fiber cement board or gypsum board requires only the screw to fix the board with the steel structure which almost causes no dust.

3 Factors to make your house cosy and comfortable

“Let’s find out 3 Factors to make your house cosy and let’s see  comfortable house guideline for the increasing intense global warming every year”

Tropical region like South Asia, South East Asia, and Africa climate is subtropical throughout most of the country. These regions have hot climate throughout the year. If you would like to talk about the ‘‘Cosy and Comfortable” condition. Many people may understand that by lowering down the temperature in the house will create the “Cosy and Comfortable” condition. 

However, in fact, the Cosy and Comfortable Condition consists of many elements e.g. temperature, wind speed, humidity or moisture, dressing and activities performing.

Comfortable House Guideline 2

The Cosy and Comfortable Condition means the condition of the temperature and the humidity of the air which make people feel cosy and comfortable, not hot, not viscous or uncomfortable. The Cosy and Comfortable Condition consists of temperature, humidity, wind speed which hits our body e.g.  Sometimes we go to the beach where the temperature is not hot. The wind flows but it is too humid, we will feel uncomfortable. 

Comfortable Bed Room Idea

However if we stay in the room with the air conditioning unit, we will feel comfortable because the air conditioning unit gives the cool temperature and blows the wind to make the air move and flow and at the same time it will ventilate the humidity.  That’s why we feel comfortable but sometimes the electricity bill rises.  Therefore in order to create the cosy and comfortable condition for living, we have to consider the following three factors

1. Heat Shield Technology

The important parts of the house are Roof, Ceiling and Partition.
When the sun shines, it will hit the roof which is on the top of the house and has more spacious area, therefore the roof will have a the great impact on the temperature inside the house.

The installation of SCG aluminium foil sheet can protect the heat directly. Heat Protection and Reflection, can reflect UV heat upto 95% and the installation of SCG Insulation Model Stay Cool above the ceiling in order to protect the heat from the spacious roof passing through the ceiling to the house.  Furthermore, it can ventilate the heat inside the spacious roof to outside by making the heat ventilator e.g. air ventilator in front of the house

How to making air ventilator on the roof to reduce heat
Making air ventilator on the roof can naturally reduce the heat

1) Making a high gable roof to let the heat float to the upper level with an air ventilation compartment or install the Eaves Liner.

2) Making a two-step roof for ventilation between each step of the roof.

The Torre Guinigi is a tower in Lucca, Tuscany, central Italy. It is a typical example of local Romanesque-Gothic architecture. The height of the tower is 45 meters with a total of 232 steps to reach the top.

Comfortable Modern House Guideline 5

For Heat reduction on the partition, we should choose the material for laying the partition with the low heat accumulation value e.g. Q-con Light Weight Concrete.  You should have the external wall painted in the light tone or bright tone e.g. white, cream, pastel or you can choose the heat reflecting paint or installing the Light Weight Concrete with the insulation on the partition exposed to the sun.  It will protect the heat more efficiently.

Selecting Q-Con Light Weight Concrete or Installing the Light Weight Concrete with Insulation. It will help protect the heat more efficiently

2. Ventilation

SCG Active Air Flow
Example of the Direction of Air Ventilation inside the house

There should be air ventilation inside the house in order to ventilate the heat and make the air inside the house flowing better and not humid.  Normally, The window will perform this function to ventilate the air inside and outside, however many residents need to close the window or live in the house with less windows which makes the air unable to flow ventilate smoothly.  As a result you can feel stuffy, warm and uncomfortable in the house.

You can install Active AIRflow™ System which is the innovative air and heat ventilation from the house and the spacious roof in order to mechanically ventilate the air and the heat from the house quickly. The house will have a good ventilation even though the house has been closed the whole day. 

The house will not be stuffy or humid.  Active AIRflow™ System will help reduce the accumulated bacteria and the room temperature will cool down faster therefore the electricity cost for the air conditioning unit will be saved  upto16-20%

3. Green Landscape

Comfortable House Guideline
Green Landscape surrounding the houses and the big trees create the fresh and shady ambience and give shade to the house.
Verticle Garden help your living more comfort
Vertical Garden suitable for limited space and area. Easy Care and you can select the varieties of plants according to your preference and need

The house should be surrounded by the Green Landscape.  The house will not only become lively but also reduce the heat in the surrounding areas. The house will be cooled.  In case you have limited space or area, you can increase the green area by vertical SCG Modular Green Hive which has been designed for easy installation and easy care which is suitable for the current city life.

Making the house cosy and comfortable does not depend on any factor. It consists of various factors which have been mentioned above.  It will help save the energy as well.
