Despite being a clean and green country, the carbon emissions in Singapore is relatively high in proportion to its size. This proposal is a response to the poor air quality that we breathe in due to the high carbon emissions.
Singapore is one of the most well-established countries in the world. We have many vehicles roaming our streets along with industrial building constantly releasing harmful particles into the air on a daily basis. In fact, a research by the National Climate Change Secretariat of Singapore stated that “Singapore contributes to 0.11% of the global emissions”. The percentage may seem small, but considering the size of our country, it is a rather large contribution. The article further shows that Singapore ranks 123rd place in terms of CO2 per dollar GDP, ahead of countries like the United Kingdom and France which are many times larger than our country. This shows that Singapore does have an issue with air pollution.
Air is essential to every human being, however, the air that we are breathing in could be affecting our health in the long run. Such harmful particles are known as ‘particulate matter 2.5’, PM2.5. It refers to tiny particles that are 2.5 micrometers (µm) or less in diameter, often called fine PM. PM2.5 causes by men are more severe than natural sources, the particles are directly emitted into the air from motor vehicles, forest burnings, and industrial gases. As they are so small and light, they stay longer in the air causing the air to be polluted and increases the chances of people inhaling it. Due to their tiny size, the particles are able to enter our lungs and circulatory system. This could cause health hazards both in the short and long run. An article published on the US National Library of Medicine National Institute of Health (NCBI, 2002) stated that “Long-term exposure to combustion-related fine particulate air pollution is an important environmental risk factor for cardiopulmonary and lung cancer mortality.”Based on a guideline by WHO, the PM2.5 levels should be at 10µgc annual mean and 25µgc for 24 hours mean. According to the psi index by NEA, the psi levels in Singapore currently falls within the range of 50 to 60µgc which are beyond the the levels listed in the WHO guidelines
The factors which have contributed to PM 2.5 in Singapore are mainly from vehicles and industrial factories. These PM 2.5 can also be the product formed by chemical reactions in the atmosphere. An article by The Straits Times stated that “due to the concentration of particle vapour and local emissions - from cars and factories”. These small-sized particles are not entirely from the neighbouring country that carries out deforestation which in the later part of the article stated “experts point to culprits closer to home: factories and cars”.
During the haze period, one of the strategies that Singaporean use to counter haze problem is to stay indoors and use air-conditioners, as is it advisable to limit outdoor activities when the PSI level is high. While all doors and windows are closed, it can limit the particles in the haze from entering the houses. However, conventional air-conditioners are unable to filter the tiny particles like PM2.5, so there are still chances of breathing them in.
When indoors, the air conditional will always be on. A building grade air conditioning uses Heating, Ventilation and Air Conditioning system, known as HVAC. The main purpose of a HVAC system is to provide thermal comfort and acceptable indoor air quality. The most common HVAC system used in buildings are called packaged rooftop units. As the name goes, it is located on the rooftops.
An ideal innovative campus should adopt an advanced approach which can circulate clean indoor air and provide a conducive environment to study without being affected by the air quality. Due to the location of the SIT@Dover, the air quality is affected by the carbon emission of cars along the highway and the industrial buildings near the coast. This results in a build-up of air pollution around the school which would be harmful to students. Inserting electrostatic precipitators to the air cons, it will filter out PM2.5 particles from the indoor air and circulate back clean air around the room. The purpose of this report is to propose to the facility manager of SIT@Dover to install electrostatic precipitators into the current campus and, to emphasise to the facility manager that this advance approach can provide a conducive learning space for the students.
