With rising temperatures outdoors, the programme Talking Point meets experts and experimenters to find out what makes 25 degrees Celsius a recommended temperature for air conditioning.
SINGAPORE: When Lee Kuan Yew became Singapore’s prime minister in 1959, the first thing he did was to install air conditioners in government buildings. In his mind, air conditioning was the key to working efficiently.
The convergence of lower skin temperatures and faster reaction times points to 25 deg C as more conducive to working, even though many of the participants, before the experiment, thought the colder the room, the higher their productivity. So why are buildings in Singapore so cold? Because “it’s easier to over-cool than to under-cool”, he said, since people who are cold can wear a jacket, whereas those who are warm cannot really be removing their clothes.In a test done by Giridharan Karunagaran, the director of the Singapore Berkeley Building Efficiency and Sustainability in the Tropics research programme, the air-con in two rooms covering 50 square metres was set at three temperatures.
Air-con systems remove heat from homes in a process called the refrigeration cycle, the same process that cools refrigerators.This process is driven by the compressor outside the home: It moves a chemical called a refrigerant between the coils connecting the outdoor and indoor units and requires the most energy in the air-con system.
Aaron Wu of Amyth Aircon Services, who shares air-con tips with his company’s 16,000 followers on TikTok, visited some homes to see if people were inadvertently working their air-con units harder than they needed to.
