Elderly and Children: For older adults, young children, or those with health conditions, the ideal temperature is slightly warmer, around 20°C. (3) Summer In summer, the goal is to keep indoor spaces cool without excessive energy consumption: General Recommendation: Aim to keep indoor temperatures between 20-22°C (4). If using air conditioning, you may wish to consider setting your setpoint to around 23-24°C to save energy while maintaining comfort. As a rule of thumb; the higher the ambient temperature, the higher your setpoint can be to still feel comfortable. Humidity's Role Humidity levels significantly impact perceived temperature and comfort (5). High Humidity: Feels warmer, so maintaining an indoor relative humidity (RH) between 30-50% can help manage comfort efficiently (5). Low Humidity: Can feel cooler but may cause dryness; using humidifiers in winter when heating is on can balance this. Water features, fish tanks/bowls and pot-plants located in the appropriate room can assist with this as well. Gender and Age Considerations: Men and Women: Studies indicate that women generally prefer slightly higher indoor temperatures than men. The average neutral temperature can be about 2-3°C higher for women. Infants: Ideal room temperatures for infants range between 16-20°C to reduce risks associated with being too warm or cold (3). Older Adults: Keeping main living areas around 20°C ensures comfort and reduces health risks linked to colder environments (3). Tips to Maintain Ideal Temperature: Insulation: Proper insulation helps maintain temperature consistency and reduce energy costs (4). Ventilation: Ensuring good ventilation, especially in high humidity areas like kitchens and bathrooms, helps maintain comfort (5). Smart Thermostats: Use smart thermostats to automatically adjust temperatures based on occupancy and time of day. By balancing temperature and humidity, you can create a comfortable and healthy indoor environment for everyone.
