The Chilly Truth About Office Air Conditioning
Many office workers have observed that their female colleagues often feel cold, regardless of how many layers they wear. We decided to investigate this phenomenon and discovered some interesting insights.
Outdated Formulas Based on Male Metabolic Rates: Many office thermostats, which control Air conditioners, still rely on formulas that were developed decades ago. These formulas were primarily designed with the metabolic rates of middle-aged men in mind. They take into consideration factors like air temperature, airspeed, vapor pressure, and clothing insulation. However, these calculations are based on the resting metabolic rate of a 40-year-old man weighing around 70 kg. It is evident that the metabolic rates of women, regardless of their weight and age, differ significantly from this standard.
Biological Differences: Studies have demonstrated that women are naturally colder than men, with a difference of approximately 3 degrees. Factors such as birth control pills can also influence a woman’s body temperature and her response to office temperature settings.
Outdated Formulas and Changing Office Dynamics: The formulas used for setting office thermostats were developed in the 1960s when the majority of office workers were men. At that time, the prevalence of female employees was much lower, which may explain the disparity in temperature preferences. However, as office dynamics have evolved, with women now comprising 47% of the workforce, it is crucial to address these discrepancies.
The Need for Change: It is evident that women feeling cold in the office is a widespread phenomenon. Uncomfortable and cold employees tend to be less productive. Therefore, there is a growing incentive to update outdated office thermostat settings. Even making small adjustments, such as reducing the cooling power by a few clicks, can be highly beneficial for the comfort and productivity of female workers.
Recognizing the temperature differences experienced by female workers is essential for promoting a more inclusive and comfortable office environment. By acknowledging the biological variations and updating thermostat settings accordingly, employers can ensure the well-being and productivity of all employees.
Assessing Cognitive Load: The Temperature Experiment
A recent study aimed to evaluate the cognitive load experienced at different office temperatures. Two temperature settings, 22°C and 25°C, were used during the experiments. The study included a total of 26 participants, consisting of 12 men and 14 women, primarily between the ages of 31 and 50.
Methodology:
- The Cambridge Brain Science (CBS) test: Participants underwent this widely-used cognitive performance assessment.
- NASA Task Load Index (TLX) questionnaire: Participants completed a questionnaire designed to gauge the perceived difficulty of the task. It included questions about task complexity and difficulty.
- Paced Auditory Serial Addition Test (PASAT): Participants took three PASAT tests of varying difficulty after a 10-minute break. They also filled out the NASA questionnaire again.
Results:
- CBS test scores: The results indicated that temperature did not significantly affect the participants’ CBS test performance. Some participants performed better at 25°C.
- EEG and heart rate monitoring: The analysis of EEG and heart rate data during the PASAT tests revealed no significant differences between the office temperatures of 22°C and 25°C.
Upon analyzing the data, no substantial differences were found in cognitive performance or physiological responses when comparing the office temperatures of 22°C and 25°C. These findings suggest that cognitive load may not be significantly influenced by slight variations in room temperature.
Note: Please keep in mind that these findings are specific to the parameters and conditions of this particular study and may not be universally applicable.
Improving Office Comfort and Efficiency with Proper Temperature Settings
- Impact of Office Temperature on Cognitive Behavior
The findings of a recent study suggest that the office temperature does not significantly affect the cognitive behavior of individuals, regardless of their gender. However, this doesn’t mean that people who complain about feeling cold are simply being unreasonable; they might genuinely be experiencing discomfort. If you have the authority to control the office temperature, it may be beneficial for overall office morale to increase the Air conditioner settings by a few degrees.
- Energy Consumption, Greenhouse Gas Emissions, and Costs
Setting the office thermostat too low has consequences beyond the discomfort of office workers. Over-cooling in large commercial buildings leads to increased energy usage, higher greenhouse gas emissions, and ultimately results in larger electricity bills.’
- Optimal Temperature Setting for Offices
On average, offices in Australia are typically set to 22°C. However, we propose changing this standard to 24°C. By doing so, you can reduce energy consumption and costs without negatively affecting the cognitive performance of office workers. Additionally, this adjustment may help alleviate the discomfort experienced by individuals who spend their day shivering.
