Humidity & Temperature

Thermal Comfort

Thermal comfort describes the state a person feels when they are neither too hot nor too cold. In addition to air temperature, it accounts for environmental factors such as humidity, airflow and clothing. Optimising thermal comfort improves personal wellbeing and helps minimise problems such as mould and damp.

The Airtopia “thermal comfort” tests are based on a combination of humidity and temperature measurements in rooms throughout your home.

The following definitions apply to thermal comfort assessments (source Health and Safety Executive):

  • Air temperature and temperature variation
    • The temperature of the room and variations in temperature from room-to-room.
  • Radiant Temperature
    • This is affected by the quantity and efficiency of heat sources in your property. Proper use of a thermostat to control radiators will help promote thermal comfort.
  • Air Velocity
    • Open windows and draughts inside your home affect how you feel. If it is too still on a warm day, your thermal comfort decreases.  In winter, you need to be draught-proof.
  • Humidity
    • Water vapour in the air can affect how comfortable your home feels.
  • Clothing Insulation
    • Dressing appropriately for weather conditions will benefit your comfort and health.
  • Metabolic Heat
    • The more we move around the warmer we become. The elderly or disabled they may feel the cold more than active people.

Controlling the temperature in your home will not only mean that you feel comfortable but will also have an impact on your utility bills.
