Daylight Glare Bibliography
Submitted by the_donn on Mon, 06/04/2007 - 17:39.Despite the growing awareness of the need for visual comfort, there is no simple method which can be used to assess all the factors (eg: glare, view, uniformity etc.) affecting visual comfort in daylit offices which are built and occupied. This report basically takes the form of a literature study. It investigates which factors influence visual comfort in daylit offices and how each of these factors can be measured to give an accurate assessment of the visual comfort of the occupants.

So far the filemanager file browser and web file manager apps have been added to the site

Assessment Method for Visual Comfort
Submitted by the_donn on Mon, 06/04/2007 - 17:59.This report has been used to lay the foundations for the development of a simple procedure to assess the visual comfort of daylit offices. Within the time constraints an actual document outlining the exact process required was not able to be produced. However, throughout this report suggestions have been made regarding what specific measurements and assessments are necessary in the procedure. The following section discusses the general needs of the procedure.

Glare
Submitted by the_donn on Mon, 06/04/2007 - 17:49.Glare is the most widely known and researched cause of visual discomfort in daylit environments. It is also a very difficult phenomenon to measure. Some people are more tolerant of glare conditions than others and the parameters affecting glare will always be different in each office.

The critical factors affecting visual comfort
Submitted by the_donn on Mon, 06/04/2007 - 17:45.Many of the factors of importance for visual comfort in daylit environments are the same as those for artificially lit environments. However, the direction, quantity, quality, variability and information content of daylight is significantly different to that of electric light, which will cause differences in the levels of visual comfort in the two lighting conditions.

DAYLIGHT DESIGN STEP 1: establish the lighting need.
Submitted by qa_admin_07 on Sun, 05/06/2007 - 22:32.An IEA research Task on Optimization of Solar Energy Use in Large Buildings established that the most important first step in designing a successful low energy solar building is to establish what metrics might be used to eastablish success. For example, with lighting quality, the client, the energy analyst and the lighting analyst and the architect (who may be one and the same person!) must establish how they are to measure success in the context of the work or activity in the building.
