Creating the ideal learning environment goes beyond just the curriculum and teaching methods; it also involves maintaining a comfortable and conducive physical atmosphere. One critical factor is classroom temperature. But what temperature is best to support students’ learning and well-being? Let’s dive into why temperature matters and explore its impact on learning.
Why Temperature Matters
Physical Comfort and Learning
Temperature has a direct impact on physical comfort. If students are too hot, they can become lethargic, irritable, or distracted. Conversely, if the room is too cold, they may feel uncomfortable, fidgety, and unable to focus on the task at hand.
Classrooms that are consistently too warm or too cold can also lead to physical health issues, such as dehydration or even headaches, which further disrupt students’ ability to concentrate. By maintaining a moderate and consistent temperature, schools can ensure that students remain physically comfortable throughout the day.
Cognitive Skill Development
Temperature plays a significant role in cognitive functioning. Research shows that extreme temperatures can impair working memory, decision-making skills, and overall productivity. In a classroom setting, these effects could mean reduced comprehension, slower problem-solving, and hindered creativity. A balanced temperature supports optimal brain function, enabling students to perform at their best academically.

How Temperature Affects Learning
When summer temperatures climb to 30°C, classrooms can become uncomfortable and disrupt students' ability to focus, ultimately impacting learning outcomes.
Impact of High Temperatures
When classrooms become excessively warm, students often experience fatigue and decreased attention spans. This is because excessive heat forces the body to work harder to maintain its internal temperature, diverting energy away from cognitive processes. Prolonged exposure to high temperatures can also cause dehydration, leading to physical discomfort and further reducing the ability to concentrate.
Impact of Low Temperatures
While less common, excessively cold classrooms can also harm learning. Students in cold environments may focus more on staying warm than on their lessons, leading to reduced engagement and participation. Additionally, cold temperatures can affect fine motor skills, making tasks like writing more challenging.

Optimal Classroom Temperature to Support Learning
So, what is the perfect temperature for a classroom? There are a range of recommendations and guidelines for minimum and maximum temperatures:
Workplace (Health, Safety and Welfare) Regulations 1992: The minimum temperature for classrooms is 16°C
The National Education Union (NEU) recommends that temperatures in school classrooms should be a minimum of 18ºC, and a maximum working temperature of 26°C.
National Association of Schoolmasters Union of Women Teachers (NASUWT): Recommends a minimum temperature of 16°C, and 13°C for areas with high physical activity
World Health Organization (WHO): Recommends a maximum temperature of 24°C for comfortable working
The Trades Union Congress (TUC) says that the best temperature for learning is between 16°C and 24°C.
Whilst there are there are no legally prescribed maximum temperatures for school premises or other workplaces in the UK, studies have shown that learning is best supported in classrooms maintained between 20°C and 22°C (68°F to 72°F). This range strikes a balance between keeping students alert and ensuring their comfort.
Why This Range Works
Energy Efficiency: Maintaining this temperature range is not only effective for learning but also energy-efficient, helping schools manage utility costs while promoting sustainability.
Seasonal Adjustments: In colder months, slightly warmer temperatures within this range can help students stay comfortable. Similarly, during summer, keeping temperatures closer to 20°C can counteract the effects of external heat.
Health Benefits: Consistent temperatures in this range help reduce the risk of heat-related illnesses, colds, and other conditions that could impact attendance and performance.
Air Quality Matters Too
Temperature isn’t the only environmental factor that affects learning. Poor air quality can worsen the effects of an uncomfortable classroom climate. A well-maintained HVAC system ensures proper ventilation, regulates humidity, and supports both temperature control and air quality, creating an all-a
round healthier environment for students.
The Role of Technology in Classroom Climate Control
Modern air conditioning and heating systems offer schools advanced solutions to maintain optimal temperatures efficiently. Many systems now include features like:
Smart Thermostats: These devices can automatically adjust the temperature based on time of day, occupancy, or weather conditions.
Zoning Capabilities: This allows different rooms or areas to be set to specific temperatures, ensuring that each classroom meets the needs of its occupants.
Energy Monitoring: Modern air conditioning systems allow for centralised monitoring and control, enabling administrators to oversee the climate of multiple classrooms with ease.
Whisper Quiet: Our systems are designed with whisper-quiet technology, operating so silently the students and teachers will barely notice it’s there.

Energy Efficient Air Conditioning For Schools
Educational institutions often grapple with tight budgets and increasing utility costs. Our energy-saving technologies are designed to help schools significantly lower electricity expenses. In addition to our energy-efficient air conditioning solutions, Cold Control provide systems that centrally manage and monitor individual classrooms or entire buildings, ensuring optimal student comfort while minimising energy waste.
