Thousands of residential homes, apartments, and condominium units are being sold in Singapore each year. This contributes to around 18 per cent of the electricity consumption in the city which comes from the energy usage inside their homes.
Aside from the electricity consumption of the residential areas, the non-residential or commercial sector are responsible for 31 per cent of the electricity consumed in the island country. Operations in buildings and offices are the main contributors to electricity consumption.
The electricity consumption from both sectors is mainly because they have air-conditioners installed. In fact, 60 per cent of the energy used comes from ACs that are running continuously day and night for both residences and commercial areas.
Homes in Singapore choose split-type air-conditioners most of the time. These units are chosen over other types of ACs because they cool efficiently, are easy to install, are energy savers, and save space inside the house.
Residences with an air-conditioner installed have steadily increased over the past decade. It is a product of growing income and accessibility to these appliances. Today, 75 per cent of homes now have an air-conditioner to cool their homes.
Public housing apartments in Singapore are less likely to own an air-conditioner. Less than 15 per cent of these residences have a unit installed. Income levels in these parts of the city are on the lower end which many point to why they don’t own an air-conditioner.
The case for private housing residents is completely different. Almost 99 per cent of households in Singapore own an air-conditioner. These speak to the purchasing power of private residents in the country. Being able to provide comfort to their homes.
Since most apartment units in the city are part of the private housing sector, the purchase of air-conditioners will steadily grow as more and more people buy houses. New homeowners include an AC unit as one of their first purchases for their homes. 
Many homeowners turn on their air-conditioners (40%) all night to help them have a comfortable sleep at night. During the first quarter of the year, AC usage lowers down because the outdoor temperature is lower.
During the summer, many households even turn on their air-conditioner during the day because they want a cooler room to fight the heat brought by the hot season. This is the time when air-conditioners are needed the most.
Educational institutions have also recently pushed for air-conditioning in public schools. Although before, schools were advised to use natural ventilation and fans. The rising temperatures within the city are making it uncomfortable inside classrooms, especially in schools where school hours are longer and there are academic activities.
Air conditioning is not a problem for many houses, schools, or offices. There are a ton of air-conditioning suppliers in the city. The presence of air-conditioning service companies is also prevalent in many of the congested areas in the city.
As more and more sectors in the country demand air-conditioning and the temperature keeps rising, we can expect more air-conditioner purchases and cleaning services in the future. Aircon suppliers should be able to provide the units and have appropriate services ready.
However, it’s recommended to use your air conditioner when necessary to save energy and avoid global warming issues.
