Abstract

The motivation of this study is to get a better understanding about the real thermal sensation of people in an office environment who undertakes moderate activities. The purpose of this study was to investigate occupant real thermal sensation at three tasks of activities and skin temperature to figure out its impact on thermal sensation in an office environment. All measurements were conducted in a climate chamber. In total, fifteen subjects were participated in three kinds of activities and skin temperatures, which is eleven locations were measured using thermocouple sensors. The results showed that the temperature is the one of the factors which affect metabolic rate. There is a strong linear relationship between these three tasks of activities and metabolic rate with the skin temperature. Furthermore, the results indicate that there was a greater increase thermal sensation when the metabolic rate 1.6. The conclusions of this study can provide some references to set a standard for air conditioning design and to set operating parameters of different functional architectures.

Highlights

Summary

Introduction

Building environment has a great impact on people’s health, comfort and productivity [1,2,3]. Thermal comfort studies are helpful to create a favorable indoor climate, maintain a productive thermal environment and keep reasonable energy consumption [4,5,6]. Most thermal comfort studies have focused on office building, classrooms or homes in which people usually sit or take low level activities. People may undertake various activities indoors such as those who work on assembling lines or those who exercise in building. With the increase of activity, the body heat production and thermal regulation process involved would be different from low activities [7]. The thermal environment that makes people feel satisfied could not be similar
