Light thesis

Light and health is an area which in recent years has undergone major changes and gained increasing attention in architectural planning. However, it is still a relatively new area, which is why a lot of effort and work is put into defining the different health aspects of light and how to better utilize them in the architecture. Much recent research reveals new beneficial aspects of light, while other research merely seems to confirm the ideas of healthy architecture in the early 20th century. The point of departure of the thesis is based on historical sources.

Light thesis

Traditionally, the northern people have been very conscious of the Nordic daylight. That is also the basis of this dissertation.

But what are the characteristics of the Nordic light? Does it differ at all from other kinds of daylight? What are the characteristics of the Nordic light and how does it manifest itself in Nordic Light thesis The dissertation is organised in four main sections: Clear sky Intermediate sky Overcast sky Relationship between cloud cover and light intensity.

The graphs illustrate how great intensity the sun and the sky lit up depending on the cloud cover extent specified in oktas. The graphs illustrate the lighting conditions of Copenhagen in June at 12 noon and a relatively thin cloud cover. The cloud cover thickness does not change from graph to graph; it is the fractional cloud cover that changes.

These ideas have come from two relatively independent sources, namely Evidence Based Design EBD and the writings of individual medical researchers. However, as EBD tends as a methodological approach to keep the architectural framework e. Furthermore, as EBD tends to concentrate on physical causes and physiological effects, while disregarding the physiological processes that mediate the demonstrated effects, it often becomes rather difficult to generalize from Light thesis results.

On the other hand, a couple of medical researchers have presented ideas about how architecture might influence healing and promote health. In the case of these writers, the understanding of the physiological processes is very robust, but a systematic understanding of the link to architecture is missing.

Thus, a consistent understanding of how the perception of architecture through physiological mechanisms might influence healing is missing. It is therefore defined as the aim of this thesis, to make a scientific contribution to the establishment of such an understanding.

It is established that the concept of the homeostatic balance is central to the concept of health and healing. Any living organism is faced with the challenge to keep its inner biochemical milieu stable within narrow bounds despite the relatively large fluctuations and physical threats that might occur in the outer environment.

Compromised health can be understood as a state of homeostatic imbalance. Research is then concentrated on finding mechanisms that tie together perception and homeostatic regulation. The stress systems is picked for further investigation, as stress basically can be defined as a state of threatened homeostasis, and a stress reaction as an adaptive behavior.

Furthermore, there is a comprehensive interaction between the stress system and the immune system. The question is then, if an architectural context to a stressful event can influence the magnitude of the stress reaction.

To investigate this, a stress experiment is carried out, using a virtual version of the so-called Trier Social Stress Test. Because the test is carried out in a virtual environment, the architecture can be systematically varied.

Using a closed room versus a room with openings, it is shown that differences can be measured in secretion of the hormone cortisol, which is a stress hormone as well as an immune regulatory hormone, but no differences can be measured in the reaction of the other stress effector system, the sympathetic nervous system.

Thus, an understanding of how systematical variations in architecture through a welldefined physiological mechanism can influence health, healing and well-being is successfully established. However, the stress test only induces acute stress which has a different effect on the immune system compared to prolonged stress, and furthermore only young healthy males were tested due to age and gender differences in stress reactions.

Thus, the experiment demonstrates that architecture can make a differences as far as cortisol is concerned, but that further research is needed to reach a comprehensive understanding of the interaction of the perception of architecture and physiology, along these lines.

However, the theory that the artificial environment that is constituted by architecture can influences physiological reactions such as stress reactions through their design is strengthened.

Light thesis

The objective was to observe the natural gaze behaviour in relation to glare for office spaces with the conditions implicitly constrained by real world luminous conditions. In the existing visual comfort models human behaviour is not sufficiently considered.

These models employ only subjective assessments, which lack an objective understanding of the factors affecting the perceptual mechanism of light-induced visual discomfort.LIGHT IN THE LANDSCAPE: DESIGNING FOR DARKNESS By Erica Marie Thum Thesis submitted to the Faculty of the Graduate School of the University of Maryland, College Park in partial fulfillment.

The purpose of this thesis is to examine the body of evidence concerning light pollution and exposure to artificial light and determine if the scientific research warrants regulatory oversight in the United States.

Our GQD-based OLEDs are designed and fabricated as two different structures: bottom emission configuration on ITO substrate and . of this thesis is color and light effects on depth perception in interior spaces.

With the emerging technologies, there has been an increase in the use of color and colored light in both exterior and interior spaces. Especially with the LED technology.
