Thermohygrometric Comfort Indicator

The Comfort Indicator allows us to easily identify the range of temperature and relative humidity that represents thermal comfort. It helps us to objectify the temperature and humidity conditions of an interior space.

Thermo-hygrometric comfort can be defined as "the state of mind that expresses satisfaction with the thermal environment and is evaluated by subjective assessment". It greatly influences our experiences in the places where we live and work, and is one of the factors that has the greatest impact on people's overall satisfaction in buildings, as it affects individual levels of motivation, alertness, concentration and mood. Its influence on the integumentary, endocrine and respiratory systems also means that thermo-hygrometric comfort plays an important role in our health, well-being and productivity.  

Beyond the individual impact, indoor thermo-hygrometric comfort also influences the energy consumption of buildings. This is due to the impact of the heating and cooling systems needed to maintain the required comfort conditions, which account for approximately half of a building's energy consumption.

The calculation of comfort conditions is defined in UNE-EN ISO 7730. However, it is an analytical and interpretative determination of thermal comfort by calculating the PMV and PPD indices and the local thermal comfort criteria on a case-by-case basis, and does not allow real-time monitoring.

InBiot offers the "Thermohygrometric Comfort Indicator" as an smart tool designed to measure and evaluate the level of thermohygrometric comfort in an indoor space. The objective of this indicator is to provide a quantitative measure of the degree of satisfaction of people in terms of temperature and relative humidity, and their impact on well-being conditions.  

The indicator defines 6 categories of impact on comfort: bad (0-16%), inadequate (17-32%), fair (33-48%), moderate (49-65%), good (66-83%), excellent (84-100%). These categories are determined by an algorithm calculation based on indoor temperature and relative humidity measured in real time.
