The ideal temperature in the office

The temperature in the office is a crucial factor for well-being, health, and productivity in the workplace. In this article, we take a close look at why the room temperature in the office is a central topic for employers and employees alike, what recommendations exist for the ideal office room temperature, and what tips are available to optimize conditions on-site. Furthermore, we clarify why an office that is too cold or too warm can impact health, and how to intelligently reduce energy costs without deteriorating the working climate.

Why the temperature in the office is so important

The temperature in the office influences the performance, physical well-being, and motivation of everyone who works there regularly. If it is too hot, the heart rate often rises, and the body loses more fluids. You quickly feel sluggish and unfocused. If, on the other hand, it is too cool, muscles tense up, you feel cold, and you do not remain productive for long. People also react with varying sensitivity to temperature changes. One person might feel comfortable at 20 °C, while another only truly thrives at 23 °C. Nevertheless, certain average values can be derived to serve as a guideline.

In many offices, the question of temperature is also a question of long-term health. High humidity combined with poor ventilation can promote mold or cause headaches, while dry air leads to irritated mucous membranes. The room temperature in the office thus interacts with other factors such as humidity, fresh air supply, and air quality. Only when all the building blocks are right do employees feel completely comfortable.

Another important aspect is that indoor temperatures often need to be adapted to outdoor conditions, which change significantly depending on the season. In winter, more heating is usually required, while in summer, air conditioning or at least thoughtful ventilation becomes necessary. Consequently, the room temperature should always be adjusted to the current weather and the individual needs of the employees.

Impact on well-being and productivity

The temperature in the office determines many details that are not obvious at first glance. Our body uses more energy at low temperatures to stay warm. At high temperatures, on the other hand, it loses energy to cool down. If the office is too warm, rapid fatigue and concentration problems can occur because blood circulation to the skin is stimulated and you sweat more easily. Productivity drops, and errors creep in more frequently. At the end of the day, it's a question of balance: even minor deviations from our comfortable temperature zone affect our mental performance.

Health also plays a major role. A permanently high or low room temperature in the office leads to altered sleep patterns, tension, and a weakened immune system. For instance, if it is constantly too cold, you are more prone to tensing up, or the blood circulation in your arms and hands deteriorates, which can lead to unpleasant side effects. If it gets too warm, the body can overheat, resulting in circulatory problems. In addition, many people do not drink enough when it is very hot, triggering headaches and a feeling of general exhaustion.

Although each person's subjective perception varies, there are proven average values for the temperature in the office that provide a good starting point. Experts often recommend a temperature between 21 °C and 23 °C for classic office activities. This usually puts you in the safe zone. While these are just rough guidelines, many studies have shown these values to be the optimal range for promoting concentration and well-being. Moreover, it also depends on other factors such as humidity, clothing, and seating position. In particular, those who sit for long periods often freeze faster than someone moving around the room. Therefore, one must react flexibly instead of stubbornly sticking to a single value.

What is the ideal office room temperature?

The ideal office room temperature does not exist as a rigid number. Rather, experience and scientific studies suggest a temperature range in which most people can work well. Many employees feel comfortable between 21 °C and 23 °C. However, every team has its own needs. For example, those particularly sensitive to cold often find 22 °C too cool, while heat-sensitive individuals already feel uncomfortable warmth at 24 °C. As an employer, it makes sense to find a healthy middle ground and not neglect appropriate dress codes. Someone who has to wear a shirt and suit in the office has different demands on the room temperature than someone working in casual attire.

The building standard also plays a role. Modern buildings are often well-insulated and have sophisticated ventilation systems, making it relatively easy to maintain a constant temperature even in cold winters. Older buildings, on the other hand, sometimes have inadequately insulated windows or drafts. In this case, the perceived temperature may differ from the readings on the thermometer. Often, a combination of regular intensive ventilation and a balanced heating concept helps. Humidity is also central. Values between 40 and 60 percent relative humidity are ideal. Then the air feels neither too dry nor too humid. This, in turn, impacts the room temperature, as cool temperatures are perceived as colder in very dry air, and warm temperatures feel more oppressive in high humidity.

To determine the ideal room temperature in the office, it is worthwhile to have regular conversations and conduct short feedback rounds. Companies that value satisfied employees should look for a dynamic solution that adapts to changing conditions.

Tips for regulating the room temperature in the office

Although it makes sense to set a uniform target temperature, practice often shows that different zones in the office have different temperatures. This is especially noticeable in open-plan offices. Employees sitting close to windows often perceive temperatures differently than those placed more towards the middle of the room. Therefore, it is worthwhile to rely on suitable measures to achieve the best possible temperature in the office.

Regular ventilation is one of the most important adjustments. Brief intensive ventilation every two to three hours provides fresh air without letting too much heat escape. In winter, it is worth turning down the heating briefly while ventilating to avoid unnecessary energy loss. In summer, you can ventilate early in the morning or late in the evening when outside temperatures are lower. Sensible temperature control is also supported by sun protection systems such as blinds or curtains. They help to prevent the offices from heating up excessively. 

Another tip is not to obstruct or block radiators. They are often blocked by furniture or covered by curtains, which reduces heat emission. In modernly equipped buildings, a thermostat often regulates the office temperature automatically, as long as the systems are configured correctly. In case of problems, a look at the settings or a conversation with the facility management is always worthwhile. Sometimes it is just minor issues like faulty sensors or incorrectly set schedules for heating phases. Those who make this fine adjustment can often significantly improve the room temperature in the office.

Health aspects

Health plays a central role when it comes to the temperature in the office. Many people nowadays spend a large part of their day sitting at a desk. If the room temperature in the office is too low, joints and muscles can cool down, leading to tension and pain in the long run. Those who are constantly freezing are more prone to poor posture and cramp up in their shoulders and neck. The consequences can be chronic tension, headaches, and a general feeling of malaise, which significantly reduces motivation.

Conversely, a temperature that is too high means an overload of the cardiovascular system. Especially in summer, this can lead to circulatory problems when the air temperature climbs above 26 °C. Headaches and exhaustion are frequent companions. Dry air in air-conditioned rooms also has a negative effect on the respiratory tract. The mucous membranes in the nose and throat dry out, offering less resistance to pathogens. Colds or other infections can spread more easily. This shows why an ideal room temperature in the office serves not only comfort but is also essential for health.

Energy efficiency and cost aspects

Especially in times of rising energy costs, this topic is also discussed from a financial perspective. Anyone who turns the heating up unnecessarily must reckon not only with dry room air but also with high operating costs. For companies, this can become a significant burden over time. Here it is worthwhile to develop a healthy cost awareness without deteriorating the working climate. Modern heating systems can often be well controlled so that they only deliver full power when it is really necessary.

There is also potential for savings when it comes to cooling. Air conditioning units consume a lot of energy, which is why you should carefully consider when and for how long they are used. In some cases, even small measures are enough to keep an office cool, such as darkening windows early or briefly cross-ventilating in the morning. An efficiently controlled air conditioning system that properly cleans and humidifies the circulating air can certainly make sense. The crucial thing is that the room temperature in the office is not excessively cooled down. Even a one to two-degree temperature difference can account for a lot of power consumption. Many people believe the colder, the better. But temperatures that are too low are not only unhealthy but usually also costly. A well-thought-out balance ensures more efficiency while simultaneously improving the working climate.

User behavior also plays a role. In many companies, computers, monitors, and other electrical devices run around the clock. This technology generates heat. Especially in smaller rooms, electronic devices can noticeably raise the air temperature. Consistently turning off devices in the evening saves electricity and avoids unnecessary heat sources. At the same time, the office remains at a more pleasant temperature in the morning. 

Dealing with temperature fluctuations

In Switzerland, climatic conditions vary greatly depending on the season and region. On a hot summer day, temperatures rise more in the city than in the mountainous areas. During cold snaps in winter, the heating sometimes ensures a warm ambiance around the clock. It is important to engage with the changing conditions and react flexibly. A fixed heating setting of 23 °C might make sense in January but perhaps be excessive in March, because the outside temperatures are already somewhat milder.

However, temperature fluctuations can also occur within a short time, for instance, when many people are in a meeting room simultaneously or when the afternoon sun shines through large window areas onto specific workplaces. Such local differences should be addressed specifically. In meeting rooms, for example, the temperature can be kept a touch lower, as the body heat of several people quickly heats up a room.

Another point is the awareness of each individual about how he or she can contribute to the room temperature. Anyone who sets the heating to the maximum level in winter and then leaves the window permanently open wastes energy and creates drafts. Responsible behavior in the workplace means being considerate and actively supporting measures that benefit the general public. Even small things, such as ventilating during breaks or closing windows in the evening, contribute to overall success. In this way, the temperature in the office is regulated better and more efficiently, and the team can benefit from a consistently comfortable climate.

Conclusion

The temperature in the office is much more than just a number on the thermometer. It determines the motivation, health, energy consumption, and general well-being of all employees. A room temperature in the office that is too cold or too warm can significantly impair productivity and lead to physical discomfort. The ideal room temperature cannot be determined across the board, but a range between 21 °C and 23 °C is considered a good starting point for office activities. However, it should not be forgotten that factors such as humidity, clothing, structural conditions, and personal preferences also play a major role.
