Notes

Three levels of indoor environmental factors, including indoor temperature and low light, have been studied. For the study of office workers, a behavioral/ neurobehavioral test has been proposed. To imitate an actual office, a field lab is constructed in an office building. All office employees are observed during work hours and observed for two weeks.
An office building is equipped with many windows to allow natural light into the office. This natural lighting creates a natural light effect that mimics sunlight, which is why office workers love it. The field laboratory is located inside the office building during the observations. One bright window is placed in front of the office. In this type of office environment, there is no artificial illumination. The primary effect of the indoor environment is the change in the ambient temperature.

The ambient temperature changed significantly over the two-week period in the field laboratory. 제주오피 The effect of temperature on the behavior and physical state of office workers can be described using a mathematical model called the Adaptation Time Curve (ATAC). This model predicts how an object's behavior will change depending on time and altitude. It is based on observations at the observation point. It can be used to predict temperature and light as well as any other quantity or class that is affected by the input over time. For temperature, the ATA curve predicts a U shaped pattern where a rapid change from bright to dark, or from cold to hot occurs.

The field lab is not equipped with offices so office workers' physical well-being cannot be measured using a self-paced visual analog scale. VASA isn't sensitive to indoor environmental quality changes and therefore cannot be used to measure physical well-being. Office workers productivity and motivation can only then be measured using objective parameters. Office workers performance and motivation from a psychological perspective can also be measured using the Performance Level Index (PLI).

When measuring indoor environment quality, there are four factors we take into consideration. These factors are total lighting intensity, background temperature, air flow conditioner (AFC) efficiency, and relative humidity (R). Because low levels of illumination can prevent heat conduction from central cooling fans to interior surfaces, the ALC efficiency is directly affected by total lighting intensity and background temperatures. Likewise, poor airflow conditioner efficiency prevents heat from getting distributed to the interior surfaces. Air flow conditioners with lower efficiency results in increased levels of indoor temperature and hence poor indoor climate quality. Because humidity levels are low, perspiration is reduced and office occupants feel more comfortable due to the effect of relative humidity.

The type of lighting in an office room can affect AFC efficiency. Bright illumination has a significant effect on the heat conduction efficiency. In offices, it may be difficult to observe a significant effect of lighting on ALC. Observed differences could either be the result of differing levels of light intensity or variations in ambient room temperature. If the indoor temperature is close to the outdoor temperature (T temp), then any difference in T temps will be small.


AFC is a powerful tool to improve the quality of office air. It can improve office performance by controlling indoor temperature, humidity, ALC reaction, and other environmental factors. It can also help reduce the temperature differential between the A/C and the external environment. This results in a better indoor environment quality.

Office workers performance and motivation largely depend on their perception of their environment. This perception can be measured by paying attention to the quality of the indoor environment. Indoor lighting can have a significant impact on office workers' performance and motivation. This motivational effect of lighting was measured using a psychological battery. The test battery consisted a simple questionnaire that asked office workers to answer questions about their motivation to work and how they feel about working.
