Thesis daylighting

The central question in this thesis is whether we can design intelligent systems that have a degree of autonomy, while users maintain a sense of control.

For these reasons, the aim of this dissertation was twofold. 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.

But what are the characteristics of the Nordic light. This is the first study where a shading device is controlled by a controller system with a low-resolution Thesis daylighting.

However, for daylight the valence of associations did not mediate preference outcomes. Then the effects of different luminance levels as well as different view outside the window on the dynamic shifts of the gaze were investigated.

The thesis is divided into three main parts. We examine this question both in the home and the work environment. 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.

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. Therefore, we did not guide the valence of associations with daylight versus electric light.

The question is then, if an architectural context to a stressful event can influence the magnitude of the stress reaction. Incorporating non-visual effects into a building simulation workflow requires a good approximation of daylight spectra as it varies with sun position and sky type.

Compromised health can be understood as a state of homeostatic imbalance. The final objective of this thesis is to support the design of healthier buildings by applying evidence-based lighting criteria, which can then inform architectural design through a simulation-based approach.

This can make life easier, but there is a risk that users experience less control and reject the system. The first chapter of this dissertation presented a review of the evidence for beneficial health effects of nature and daylight.

A uniform research paradigm was chosen to test these effects; ego-depletion. This supported the conclusion that physical and photometric parameters alone are not sufficient for a robust prediction of discomfort glare.

The causal directionality of this relation was further investigated for natural environments by guiding the valence of associations. 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.

The thesis is closed with an analysis of a simple case study. However, as EBD tends as a methodological approach to keep the architectural framework e. The collection of temporal variables and personal factors — thereby examining the scatter in glare responses across the independent variable time of day and isolating potential confounding variables — enabled to identify factors that could influence the subjective evaluation of glare sensation along the day.

These findings were found for explicit preference, but not for implicit preferences. We therefore propose to improve the acceptance of automated blinds by making users aware of how the system works and how its use affects energy consumption.

First, we wanted to test whether daylight and natural environments share underlying psychological mechanisms. The graphs illustrate the lighting conditions of Copenhagen in June at 12 noon and a relatively thin cloud cover.

Performance predictions must also account for occupant behavior and scheduling, which brings us to the question:. This thesis focuses on the manner in which two contemporaries, Alvar Aalto and Louis I. Kahn, each recognized the potential for and developed techniques toward the realization of daylighting's efficacy for the clarification of the architect's spatial concept.

Daylighting has been a part of built forms throughout architectural history. Interest in using daylighting as a major design element has varied with the social and economic forces of the time. Daylighting Lab → Thesis/Dissertations Thesis/Dissertations Chunliu Mao, "Analysis of Building Peak Cooling Load Calculation Methods for Commercial Buildings in The United States", The thesis proposes a simple method to aid urban designers in the daylighting aspect of the decision-making process in the early stages of design when the outline of the city is defined.

As input to this simple method, complex simulations of the urban canyon structure were made. On Jan 1,Prof Dr (and others) published a research thesis starting with the following thesis statement: Daylighting has been a part of built forms throughout architectural history.
