Are you aware that the trees around your house might help you to reduce the money spent on air-conditioning system?
This can be done where the process when the water evaporates from the leaves of the plants, it will cool down the air. With the weather getting increasingly hot in Singapore due to the change of climate, it is essential for us to preserve the greenery in Singapore.
In Singapore’s climate, every degree is importance where it will affect the comfort of people living here. This is extremely important in a densely city in Singapore. The concrete surfaces of the buildings will absorb the heat during the day. However, the buildings are packed which will prevent the heat from escaping during this night. This is so called the urban heat island effect in Singapore.
In order to reduce the electricity bills and best optimize the temperature in various locations such as parks and reserve, you need to regularly engage in regular servicing Singapore for your air-conditioning system. Other than that, you can incorporate sensors into your air-conditioning system to control the cooling performance and electricity usage of your system. Hence, when the outdoor temperature cools down, the temperature for the indoor unit will also be reduced. Thus, the electricity usage for your air-conditioning system in the reserve such as in the visitor centre will be significantly reduced. Thus, also engage in regular servicing and maintenance to keep your air-conditioning system in good performance and condition
There’s is a study that are being carried out in Singapore where it has found out that rural areas in Singapore such as Lim Chu Kang where it is 3 degrees Celsius cooler at night that urban areas such as city hall. This is due rural areas are flat and are open enough to allow heat to escape during the night.
Depending on the weather, when the night is clear, the difference in the temperature in the rural and urban area can be up to 7 degrees Celsius. This is because there are no clouds to prevent the cooling process and other is no winds that blows the warm air from the urban area.
During the day, the temperature of the day rural and urban areas is equally hot. However, tall trees are able to reduce the temperature.
According to the temperature sensor in the middle of the day, the temperature in the forested area are around 1.5 degree Celsius cooler than the urban area. This is due to the evaporative cooling and also the shades that tall trees provide. Do not underestimate the cooling effect as this can be applied even in a small park in Singapore. One of the example is Telok Kurau Park, where it is filled with large tall trees that have shades around.
A study in 2004 found out that during a calm and clear night, the park can be as cool as 2 degree Celsius as compared to the surroundings. The cooling effect can be felt which are known as the edge effect. Thus, if you remove the green area in the city, the edge effect will also be removed. This will cause discomfort to people living there and could cause higher electricity bills because people will be blasting their air-conditioner to fight the heat.
According to the Centre for Climate Research Singapore, they have projected an increase of around 1 to 4.5 degree Celsius across regions in Singapore by end of this century. Despite the fact that efforts done by Singapore to counter global warming is minimal, we still have our own parts to play.
What we can plays a part as a Singaporean is to try to reduce the heat island effect in Singapore.
According to the Urban Redevelopment Authority (URA) around 9% of Singapore’s land are set aside for parks and nature reserves. URA mentioned that there is policies that take into consideration of Singapore’s development and greenery project. Greenery are able to serve many purposes in Singapore. Other than providing cooling air and act as a habitat for the wildlife, it helps to relax one’s mind and as a noise barrier. Other than that, in case of flooding, it is one of the effective flood alleviation mechanism as vegetation helps to retain these rainwaters effectively.
