Various species can survive and thrive in daylight thanks to its many advantages. Light affects both the physiology and behavior of humans. Spectral composition provides people with a more optimal view of situations because of the spectral composition of natural light.Natural light can be used as an illumination source in buildings. It will reduce artificial lighting usage, or, in other words, the amount of electricity consumed during the day, supporting the sustainability goals. Buildings require windows as essential structural elements so that light can enter the interior and occupants can see outside. Aside from improving visual performance, it is beneficial to embrace natural light and shade in interior spaces at all times of the day to enhance their aesthetic appeal.An individual's connections to their surroundings, both externally and internally, can influence their personality. An individual's personality can be influenced by the design of the building or the window and vice versa. Depending on a person's personality, the interior design of a building, window size, table position, etc. may differ.Generally, building and construction areas are expected to be durable and sustainable. Sustainable development is dependent on the health of its inhabitants. The effect of daylight on behavior and architecture can help us to develop healthier lifestyles and cultural attitudes. In the future, both the healthcare sector and the architectural sector will benefit from good lighting.This thesis describes a study about impacting the personality traits on work/educational environment satisfaction with regards to window criteria and table position that was carried out at the room laboratory at the Department of Architecture and Technology at the Norwegian University of Science and Technology, Trondheim, Norway, in 2022. A total of 70 adults visited the three different built rooms. They also answered psychological and architectural questions.They were required to evaluate the different items from their preferred working (sitting) position in one of the rooms that they liked the most. According to the results, most people preferred big-sized windows. Furthermore, close to and in front of the window was the favorite table position for participants. Also, in their opinion, the best layer of view was the sky; as well as their liking for the existence of the curtain in their offices/classes.Its results will support health and well-being by means of technological and spatial innovations that take into account the relationship between the well-being of people (especially their mental well-being) and the sustainability of buildings.
