Evaluation of lighting conditions in portable classrooms and analysis for alternative daylighting systems [PDF]

open access: yes, 2017
Lighting conditions in multiple classrooms in central Texas were assessed, and the feasibility of improving portable classroom daylighting via alternative daylighting systems was also evaluated.

Analysis of Point Daylight Factor (PDF) Average Daylight Factor (ADF) and Vertical Daylight Factor (VDF) under various unobstructed CIE Standard Skies

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract The usual method for computing natural illuminance for a given location in a building is the daylight factor (DF) approach, which is based on the traditional overcast sky without sunlight, as defined by the International Commission on Illumination (CIE).

Effects of reduced dissolved oxygen concentrations on physiology and fluorescence of hermatypic corals and benthic algae. [PDF]

open access: yes, 2014
While shifts from coral to seaweed dominance have become increasingly common on coral reefs and factors triggering these shifts successively identified, the primary mechanisms involved in coral-algae interactions remain unclear. Amongst various potential

Investigating Correlation of Window’s Configuration of Classroom and Daylight Indicators in Hot and Arid Region of Kerman City [PDF]

open access: yesIranica Journal of Energy and Environment
For reading and writing in classrooms therefore a lot of energy is consumed in educational spaces. Limitation of fossil fuels and environmental pollution are two subjects that demonstrate the importance and significance of the present study.

Gender differences in Everyday Risk Taking: An Observational Study of Pedestrians in Newcastle upon Tyne [PDF]

open access: yes, 2018
Evolutionary psychologists have put forward that there are evolved differences in risk taking between men and women. Potentially, these also play out in every day behaviours, such as in traffic.

Daylighting in classrooms - the daylight factor as a performance criterion

open access: yes, 2014
Recent research has shown that environmental conditions in classrooms, and namely daylighting conditions, can influence students health, well-being and performance. In the last years several studies, dealing with the effects of environmental conditions in classrooms in the learning process, have been published (Winterbottom, & Wilkins, 2009; Barret ...

Daylighting Evaluation of Perforated Screen Façade with Light Shelf in the Tropics

open access: yesDimensi: Journal of Architecture and Built Environment
The use of large glass facades in buildings without external shading devices leads to a high daylight level, uneven daylight distribution, and glare. A perforated screen facade (PSF) is one of the shading systems that can provide daylight and view and ...

THE EFFECT OF OPENING DISTRIBUTION AREA MODIFICATION ON HORIZONTAL LIGHT PIPE DAYLIGHT PERFORMANCE

open access: yesDimensi: Journal of Architecture and Built Environment, 2021
A deep-plan office building design limits daylight access on the workspace distant from the side window. Horizontal Light Pipe (HLP) is one of the light transport systems that can deliver daylight to these areas.

The effectiveness of dayligting through the toplighting design in large-volume building models

open access: yesARTEKS : Jurnal Teknik Arsitektur, 2021
The utilization of daylighting as an effort to reduce the usage of building energy needs to be optimized. This is because, low-rise buildings with large volumes require specific strategies for proper light distribution throughout the space.

Chirality and the origin of atmospheric humic-like substances [PDF]

open access: yes, 2010
Aerosol water extracts and atmospheric humic-like substances (HULIS) obtained from PM2.5-fraction aerosol samples collected in a rural/continental background environment and in an urban environment in spring and summer, and at a tropical site that was ...
