This year the heat arrived very early. At the end of May, a powerful anticyclone caused record temperatures throughout Europe for many days. One of the consequences of the extra heat is that air conditioning systems in homes and businesses have been turned on earlier than usual.

Although the definition of a comfortable room temperature is subjective and varies from person to person, it is important to pay attention to general rules. Different regulatory authorities have established 24ºC-26ºC as the correct range in summer. It is neither healthy nor comfortable for the body to maintain indoor-outdoor temperature differences of more than 8-10°C, as going from one to the other can cause thermal shock.

In large rooms and spaces, the room temperature does not always match the thermostat setting. Table-top thermometers let you know exactly what the temperature is in the work area.

It is more energy efficient to keep climate control devices on and well programmed, rather than switching them on and off, and it is important to keep windows closed, especially in corridors and passageways, as they allow dirt, noise, heat and insects to enter.

In the current climate emergency situation, there is an urgent need to reduce energy demand from heating and cooling homes and workplaces, especially in cities where 70% of the energy produced is consumed.
