The right workplace temperature – a balance between comfort and energy efficiency
The right workplace temperature – a balance between comfort and energy efficiency
The temperature in the workplace is more than just a matter of comfort. It affects employees’ wellbeing, productivity, and the organisation’s energy consumption. Too warm, and concentration drops. Too cold, and muscles tense up. Finding the right balance between comfort and energy efficiency is therefore an essential part of a healthy and sustainable working environment.
Why temperature matters
Research shows that temperature has a direct impact on performance. When it’s too hot, fatigue sets in and focus declines. When it’s too cold, the body uses energy to stay warm, which can lead to stiffness and discomfort. Both extremes can reduce efficiency and increase the likelihood of mistakes.
Temperature is also one of the most common sources of dissatisfaction in offices. People experience heat differently depending on factors such as age, gender, clothing, and activity level. That’s why there is rarely one temperature that suits everyone.
What do the regulations say?
In the UK, the Health and Safety Executive (HSE) recommends that workplace temperatures should be at least 16°C for sedentary work, or 13°C for work involving physical effort. There is no legal maximum temperature, but employers are required to ensure that conditions are reasonable and do not cause discomfort or health risks.
These guidelines are flexible, as comfort depends on more than just the thermometer reading. Air movement, humidity, and individual preferences all play a role. The key is to maintain a stable and comfortable environment throughout the day.
Comfort and energy – two sides of the same coin
Creating a comfortable indoor climate is not only about wellbeing but also about energy use. Heating and cooling account for a large share of a building’s total energy consumption. Every degree the thermostat is raised in winter or lowered in summer can increase energy use by around 5–10 per cent.
That’s why it makes sense to find a compromise where comfort and efficiency go hand in hand. For example, keeping the office around 20–22°C in winter and 23–24°C in summer can provide a good balance. Adjustments can then be made through ventilation, shading, and appropriate clothing rather than constant changes to the thermostat.

Small changes, big impact
There are many ways to improve indoor comfort without turning up the heating or air conditioning:
- Use blinds or shading to prevent overheating on sunny days.
- Ensure good ventilation. Fresh air helps regulate temperature and prevents stuffiness.
- Maintain heating and cooling systems. Poorly balanced systems can cause uneven temperatures and waste energy.
- Involve employees. Allow for small personal adjustments, such as desk fans or extra layers, so everyone can find their own comfort zone.
These simple measures can increase satisfaction while reducing energy consumption – a win for both people and the planet.
Technology as a helping hand
Modern buildings increasingly use smart control systems that automatically adjust temperature, lighting, and ventilation based on occupancy and conditions. Sensors can detect how many people are in a room and adapt the temperature accordingly, ensuring comfort without wasting energy on empty spaces.
Even in older buildings, simple solutions such as programmable thermostats, timed heating, or energy monitoring can lead to noticeable savings.
An investment in wellbeing and sustainability
Finding the right workplace temperature is ultimately about creating an environment where employees can thrive and perform at their best – without compromising the climate or the company’s finances. A well-balanced temperature policy is not just a technical matter but a strategic investment in both people and sustainability.
When comfort and energy efficiency work together, the workplace becomes a space where everyone – and the environment – can breathe a little easier.
