Is 25°C the new 22°C for the office?

Slightly higher office temperature won’t affect productivity

Office air conditioning systems are usually set at 22°C as the optimum temperature for comfort and productivity. However a recent study based in Australia is saying that turning the heat up a little to 25°C will allow workers to be just as productive and have the added benefit of saving money and energy.

What did the study entail?

The experiment took place at Sydney University where volunteers were asked to undergo performance tests under varying air conditioning temperature settings between 22°C and 25°C. The participants (made up of 26 office workers) were grouped into two or four and given half an hour to acclimatise to the environment and were then asked to take two one hour tests. Whilst taking these tests, brain and heart activity were measured. The participants were also required to fill in a questionnaire before each one hour session.

Researchers found that the test scores weren’t significantly affected by the varying temperatures.

What does it all mean?

Although the study was focused on Australia, during the summer, UK offices could make significant savings in money and energy consumption by setting the temperature a little higher than usual without significantly affecting productivity. The 22°C which is usually set in offices can be a little too chilly for some, therefore by setting the temperature a little higher this will keep more people happy.
