We spend up to 90% of our day indoors—whether for living, working, or leisure. This is precisely why architecture and building technology must be designed to ensure we feel truly comfortable in these spaces. However, well-being does not depend solely on room temperature, but above all on the right heating. Variotherm shows what is important for thermal comfort. 

To understand the concept of comfort, it can be helpful to first explain the basic principle of heat and cold. Heat indicates how much thermal energy is transferred from one body to another. When two bodies with different temperatures come close to or in contact with each other, the one with the higher temperature transfers it to the body with the lower temperature. This transferred energy is the heat. The unit for energy is a joule (1 J).  

Comfort describes the state when the indoor climate and air quality are adjusted so that people feel completely comfortable in that space. 

According to the definition, thermal comfort describes how comfortable people feel in a room in terms of temperature – both in summer and winter. Those who are neither too warm nor too cold feel comfortable in terms of climate. So, those who are satisfied with the temperature, humidity, and air movement in the room feel thermally comfortable.  

People also influence comfort through their clothing and activity. For the human body, it is important that it can release as much heat as it generates: The body must release heat evenly in all directions – then it feels comfortable. 

There are a number of different factors that contribute to a comfortable atmosphere. These include thermal and non-thermal factors. The latter include noises, room odors, irritations from people, allergens in the air, or even the perception of light. The thermal factors primarily include the temperature of the room air and surfaces, the distribution of air temperature, air movement, humidity, as well as the clothing and activities of the people in the room.

The question of what temperature we humans feel most comfortable at concerns us practically every day. Do we need to turn the heating up or down to achieve the perfect room temperature?

The answer to the question of the most comfortable temperature is quite simple: Yes, there is an optimal comfort temperature for us humans – even though everyone has their own individual sense of well-being. However, there is a temperature range in which we all feel particularly comfortable. This is between 20 °C and 22 °C.

Of course, the perfect room temperature also depends on the respective room and its conditions. The temperature in the bedroom can be different from that in the living room or in sanitary rooms. Therefore, it is important to choose heating systems that are comfortable and individually adjustable.

For example, a room temperature between 20 °C and 23 °C is considered comfortable in the living room, while a temperature between 17 °C and 20 °C is perceived as pleasant in the bedroom.

Surface heating systems have the great advantage that they require less temperature for the feeling of comfort when heating in winter and less cooling for pleasant well-being in summer. This saves valuable energy and thus protects your budget.
