What is the ideal office temperature?

A good temperature in the office is essential for comfort and productivity. In hot or cold conditions, employees have less energy and cannot concentrate as effectively. A pleasant temperature creates a comfortable work environment. Good office heating and air conditioning play a key role in this.

What is the best office temperature?

The ideal working temperature in the office can generally be found between 18 and 23°C. Within this range, most people feel comfortable enough to focus without distraction, which is essential for maintaining productivity throughout the day. Too much heat can leave employees feeling sluggish or tired, while cooler conditions may cause discomfort, such as cold fingers, that makes tasks harder to complete.

What does the HSA say about the temperature in the office?

According to the Health and Safety Authority (HSA), temperature is only one factor in how warm or cold we feel in the workplace. Other influences include humidity, air movement, and exposure to sunlight or heat sources. Clothing and the level of physical activity also play an important role.

For office environments and other sedentary work, the law requires a minimum workplace temperature of 17.5°C, “so far as is reasonably practicable.” For other light sedentary work, the minimum is 16°C.

While there is no legal maximum workplace temperature in Ireland, the HSA advises that most people find a comfortable range in offices to be between 18°C and 23°C. If temperatures rise significantly above this range, employers should take steps to ensure comfort and safety, such as improving ventilation, reducing direct sunlight with blinds or films, and considering flexible dress codes in hot conditions.
 

When it’s too hot, productivity drops

When it’s too hot, our bodies work harder to try to cool down. This requires energy, causing employees to tire quickly. Sweat also evaporates less effectively in humid conditions, making cooling even harder. Research shows that productivity can fall by as much as 10% at 30°C compared to a comfortable 22°C. High temperatures also reduce concentration and increase the likelihood of mistakes.

Cold temperatures aren’t ideal either

When the workplace is too cold, employees often experience stiff muscles and cold fingers. The body uses extra energy to stay warm, which reduces productivity. To help conserve heat, people can adopt awkward postures, such as hunching shoulders, keeping arms close to the body, or tensing up, which can lead to physical discomfort. You can prevent these complaints with additional heat, such as from an electric heater.

What influences office temperature?

The temperature in the office depends on several factors:

• Outside temperature: On warm days, the indoor temperature rises faster, while in the winter the heat is lost quicker.
• Number of employees in the office: People give off heat, which means busy offices heat up faster.
• Heat sources: Computers, printers and lighting emit additional heat.
• Insulation of the building: Poor insulation allows a lot of heat to escape or to enter.
• Ventilation: Without good ventilation, warm air remains trapped and it quickly becomes stuffy.
• Window coverings: Curtains or blinds keep the sun out, keeping it cooler.  

Tips for the ideal office temperature

With these tips, you can ensure a pleasant office temperature.

• Use air conditioning to keep the room warm or cold
• Keep the room cool with an air cooler or opt for a fan
• Use insulation foil to keep heat out in the summer and keep it in in winter
• Install draft excluders and sill strips to keep heat inside
• Heat the office spaces with electric heaters
• In case of prolonged high temperatures, take measures such as extra breaks or an adjusted work schedule
• Adjust the dress code on hot or cold days

A pleasant working environment prevents health problems and increases job satisfaction. By managing temperature and ventilation effectively, you can maintain productivity.
