Photopolymerization is an active research field and recently, a great deal of efforts has been devoted to replace the energy-consuming UV irradiation setups by the popular and easily available energy-saving light-emitting diodes (LEDs). With aim at going a step further, sunlight can be used as an inexpensive and unlimited light source to perform po...
The Netherlands is facing a housing demand of 1 million homes before 2030. Most of these residences are planned to be built in and around existing cities, causing an increase in urban densities with sub-optimal indoor daylighting conditions as a result. Simultaneously, the daylight assessment methodology for buildings in the Netherlands is set to c...

This study aimed to evaluate the evidence-based design of the hospital physical space effect on the burnout of nurses and physicians during COVID-19. The research question was to identify the connection between daylight, nature-view windows, and hospital staff burnout during Covid-19. The evidence-based design in the hospital environment affects th...

Light is the primary stimulus for synchronizing the circadian clock in humans. There are very large interindividual differences in the sensitivity of the circadian clock to light. Little is currently known about the genetic basis for these interindividual differences. We performed a genome-wide gene-by-environment interaction study (GWIS) in 280 89...
Se evaluó el nivel de deslumbramiento producido por nueve textiles. Este tipo de sistema de sombreado muchas veces es comercializado sin una adecuada caracterización fotométrica, lo que conlleva a una aplicación inadecuada de los mismos, produciendo incrementos en las molestias visuales de los usuarios y mayores consumos de energía. Para evaluar el...
Long day (LD) treatment is frequently applied for horticultural crops, including strawberry, and sufficient effect similar to 4 to 6hours of day time elongation in the evening can be achieved by 1 to 3hours of night break in the mid night. Incandescent lamps (IC) have long been an important light source, but the general incandescent lamps are out o...
I samhället idag är det en viktig diskussion pågående om att renovering av befintliga bostäder och lägenheter ofta är ett mer hållbart alternativ än att bygga nytt, då det minskar miljöpåverkan. Tyvärr genomförs många renoveringsprojekt enbart genom att byta ut material, utan att ta hänsyn till hur bostadens rörelse och rytm kan förbättras på olika...
Purpose: The purpose of this study was to plan blueprints for a school located Härbregatan and Vallby Skolgata in Västerås with a focus on energy losses and window placement to choose the most suitable types of windows to obtain a good internal environment. Method: The methodology used to conduct this thesis was based on earlier case studies, liter...
The conditions for housing construction changed in Sweden during the 1990s. The political situation turned after the election in 1994, which later meant new regulations concerning increased construction VAT, property tax and reduction of interest subsidies. Costs for construction increased and this meant that attractive locations, especially in cit...
Driving sleepiness is a serious problem worldwide. It is of interest to develop reliable sleepiness detection systems to implement in vehicles, and for such a system both physi-ological data and driver performance data can be used. The reasons for driver sleepiness can be many, where an interesting factor to consider is the light condition of the e...
