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 monitored during work hours and for two weeks.
Many windows are installed in offices to let natural light in. 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 indoor environment's primary effect is the temperature change.

The ambient temperature changed significantly over the two-week period in the field laboratory. A mathematical model called the Adaptation Time Curve can be used to describe the effect of temperature on office workers' behavior and physical states. 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 for temperature and light, and for any other quantity or class of quantity which is a change of the input over time. The ATA curve predicts a U-shaped pattern for temperature. This is where there is a rapid change in temperature from bright to dark or from cold to warm.

The field lab is not equipped with offices so office workers' physical well-being cannot be measured using a self-paced visual analog scale. 오피출장 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. The Performance Level Index (PLI) can be used to measure office workers' performance and motivation.


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). Total lighting intensity and background temperature directly influence the ALC efficiency because low levels of illumination prevent the heat conduction from the central cooling fan to the interior surfaces of the room. 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. Relative humidity directly influences the comfort ability of office occupants because high levels of humidity reduce perspiration.

AFC efficiency is affected by the type of illumination in an office room. Bright lighting has a significant impact on heat conduction efficiency. It may be difficult to see the significant impact of lighting on ALC in offices. Observed differences could either be the result of differing levels of light intensity or variations in ambient room temperature. However, if the indoor room temperature is close to the mean outdoor temperature (T temp), then the difference in T temps would only be a small one.

AFC is a powerful tool for improving the office air quality. It can improve office performance by controlling indoor temperature, humidity, ALC reaction, and other environmental factors. It can also reduce the temperature difference between the A/C environment and the outside environment. This improves the indoor environment's quality.

The perception of the environment is a key factor in office workers' motivation and performance. They can measure this perception by observing the different aspects of the indoor environment quality. 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.
