Light is a form of energy produced by a luminous object which occurs as electromagnetic radiation and is closely related to other forms like radio waves, microwaves, gamma rays, infrared, UV and X radiation. The different kinds of radiation can be classified by using wavelengths. Only a small section …

Purpose: This study aims to qualitatively examine the relationship between the indoor environmental quality (IEQ), lecturers’ and students’ perceived internal responses and academic performance. Design/methodology/approach: To capture user experiences with the IEQ in classrooms, semi-structured interviews …

This study explores if multiple alterations of the classrooms' indoor environmental conditions, which lead to environmental conditions meeting quality class A of Dutch guidelines, result in a positive effect on students' perceptions and performance. A field study, with a between-group experimental design, …

Several studies found that classrooms' indoor environmental quality (IEQ) can positively influence in-class activities. Understanding and quantifying the combined effect of four indoor environmental parameters, namely indoor air quality and thermal, acoustic, and lighting conditions on people is essential …

This study contributes to finding out how Digital Signage together with sensory perceptions should be placed within the design of physical clothing stores to optimize the guests ' experience. In terms of sensory perception, the focus was on the environmental factors of music and lighting, and the design …

In this charging plaze energy exchange will be done by a DC microgrid between PV, V2G electric cars and lighting. Control is done autonomous with Droop Rate Control.

The European research project Smart Light Concept (SLIC) is a collaboration between 2 knowledge institutions, 6 local authorities and 1 grid operator. They are working together to investigate in practice what investment in sustainable public lighting can contribute to reducing carbon emissions. They …

Purpose: To establish age-related, normal limits of monocular and binocular spatial vision under photopic and mesopic conditions. Methods: Photopic and mesopic visual acuity (VA) and contrast thresholds (CTs) were measured with both positive and negative contrast optotypes under binocular and monocular …

Several studies found that classrooms' indoor environmental quality (IEQ) can positively influence in-class activities. Understanding and quantifying the combined effect of four indoor environmental parameters, namely indoor air quality and thermal, acoustic, and lighting conditions on people is essential …

The application of DC grids is gaining more attention in office applications. Especially since powering an office desk would not require a high power connection to the main AC grid but could be made sustainable using solar power and battery storage. This would result in fewer converters and further advanced …
