Each individual has his or her subjective perception of comfort. However, we can attempt an objective definition of it as a "feeling of physical and mental well-being". In the 1960's and 1970's, scientific studies such as those conducted by Professor Ole Fanger have even drawn up a "theory of well-being".
These studies have found that this sensation is influenced by a number of factors, not least of which is the temperature.
The ideal values for well-being are 21°C in the winter and 26°C in the summer.
Outside of this range, we don't feel quite as well. The correct harmony with the spaces where we live is an essential choice.
The right climate consists of achieving a balanced relationship between the individual and the environment around him or her. This relationship depends on a number of factors. Generally, they can be divided into environmental factors (temperature, relative humidity, air speed and distribution) and individual factors (physical activity performed, thermal resistance of clothing, etc.).

Changes in outdoor temperature as the seasons change is a condition of nature. However, for the purposes of our well-being, the temperature in the home must be adjusted perfectly in each room according to precise reference values.In order to achieve this result, you must define the correct temperature setpoint for each room, based on the activities that occur there and for each season, and avoid large oscillations through careful adjustment.
Winter temperature: 20°C
Summer temperature: 26°C
Air distribution and speed
Air distribution and speed significantly affect the level of perceived comfort. Proper management of these parameters prevents stratification, draughts, air stagnation and problems associated with them.

Everyone knows how much humidity affects our comfort. The environment must be neither too dry nor too humid. Excessively low humidity causes problems such as headaches, dryness of airways and discharges of static electricity. On the contrary, excessive humidity causes a feeling of mugginess, and the proliferation of moulds and bacteria. The humidity must therefore be controlled to make the indoor environment independent from weather conditions.
Humidity: 40% - 60%

In modern construction, new houses are required to have increasingly higher levels of thermal and acoustic insulation, which also affect the greater insulation of outside air.
The air in the home tends to stagnate and its quality gradually deteriorates due to pollutants released by persons, animals and objects. Therefore, forced air recirculation is required. This must take place in controlled conditions for the insertion of filtered air at an ideal temperature and humidity.
The presence of noise and vibrations in the home can be a major disturbance to people. In addition the noise pollution in and of itself, they may combine with slightly unfavourable conditions of temperature and humidity to create an irritating situation in the home.
The air conditioning system must ensure the lack of noise in the air conditioned places and outside the building, while at the same time preventing the transmission to the system of noises from outside.
