Abstract
Nowadays, we spend most of our time inside buildings. Thus, ensuring adequate thermal comfort is an important issue. The paper discusses the issue of thermal comfort assessment in the intelligent low energy building “Energis” of Kielce University of Technology (Poland). The tests conducted in a selected lecture theater focused on collecting anonymous questionnaires containing thermal sensation and air quality votes of the respondents as well as performing measurements of indoor air parameters (air and globe temperatures, relative humidity, air velocity and CO2 concentration). Based on the obtained data a comparison has been done between the actual sensation votes of the volunteers and the calculation results performed with the Fanger thermal comfort model. Two indices have been considered in the paper: PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied). A modification of the model has also been proposed, which considers the impact of the carbon dioxide concentration on thermal comfort.
Highlights
The issue of thermal comfort is of increasing importance in the existing world
The research carried out in an intelligent building showed that the number of people dissatisfied with the prevailing conditions exceeded 10%
Most people prefer a warmer environment, so this could explain the number of dissatisfied people
Summary
The issue of thermal comfort is of increasing importance in the existing world. An increasing number of people spend their time indoors. This increases the interest in the conditions in a given room. More and more people are trying to ensure thermal comfort by using appropriate air-conditioning and heating devices. Proper thermal conditions are key elements for our well-being, health and productivity. Not providing the right conditions can adversely affect our immune system and we start to feel tired. That is why it is so important to ensure adequate parameters of the air in the room and try to keep them at an appropriate, as far as possible unchanging level. Despite many years of research on this topic, many questions still remain unanswered
