1. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design
Sammanfattning : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.

2. Do lighting control and user interface design matter to occupant behaviour? The case of optimal lighting use in non-residential buildings
Sammanfattning : The lowering of energy use from artificial lighting in buildings is vital to reaching the goal of reducing CO2 emissions. Hence, changes in individuals’ behaviours regarding lighting use have received increased attention. Feedback on energy use has often been used to change individuals’ behaviour. LÄS MER
3. Daylight compliance of multi-dwelling apartment blocks : Design considerations, evaluation criteria and occupant responses
Sammanfattning : This thesis examines the daylight compliance of residential spaces, in particular apartments in multi-dwelling building blocks, and provides knowledge that may prove useful for the development of future daylight criteria for dwellings. The implications of design choices on daylight compliance of spaces and the effect of daylight criteria on the level of compliance are at the core of this work. LÄS MER
4. Measurements of X-Ray Emission from Laboratory Sparks and Upward Initiated Lightning
Sammanfattning : In 1925 Nobel laureate R. C. Wilson predicted that high electric fields of thunderstorms could accelerate electrons to relativistic energies which are capable of generating high energetic radiation. The first detection of X-rays from lightning was made in 2001 and from long sparks in 2005. LÄS MER
5. Bilayer Light-Emitting Electrochemical Cells for Signage and Lighting Applications
Sammanfattning : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. LÄS MER
