Talk:Daylighting (architecture)

message: One important element of creating daylighting is the use of clerestory windows. These are high, vertically-placed windows oriented to the south to admit sunlight for daylighting.

message: This article suggests (without citation) that aerogel is used as transparent insulation.  I find this highly improbable.  While aerogel is transparent and insulative, it is also phenomenally expensive.  I suspect this to be original research.  I am removing it.  If anyone finds a source, feel free to put it back.  —Preceding unsigned comment added by 207.119.56.245 (talk) 06:55, 25 January 2009 (UTC)

message: Daylighting is a technical term given to a common centuries-old, geography and culture independent design basic when "rediscovered" by 20th century architects
An awkward sentence with little context; the quotation marks make the passage sound pompous and patronising.  —Preceding unsigned comment added by 82.32.6.142 (talk) 02:18, 19 March 2011 (UTC)
thread_title:  Poorly "worded" you might say 

message: Hi, I am very inexperienced at Wikipedia so have no idea what would be the best way to implement this, but "Daylighting" also refers to exposing underground utilities (to daylight). This is done to ease large-scale excavation and for safety. See the following:
Badger Inc.
Central Hydro Vac Ltd. 
Precision Daylighting
Atlas Daylighting

message: I propose to merge Passive daylighting and Active daylighting into Daylighting. I see a substantial overlap in content in that the passive daylight page offers little more than a definition and some examples, while the active one has a definition and a list of companies. I believe the distinction between passive and active is actually clearer when introduced within the broader discussion of the daylighting article. The specific examples can be identified as "passive approaches to daylighting" or "active approaches" when mentioned on the daylight page, and/or in their own articles if applicable. The daylighting article is of reasonable size, and clarifying the distinction between active and passive means would improve the article without causing problems with size.AdabhaelTalk 21:27, 3 November 2019 (UTC)

thread_title:  Merger proposal 

message: Heliostats need to be active to reflect the sun in the desired direction using a plane mirror. 
For high temperatures heliostats can concave and parabolic fir all radial directions perpendicular to direct sunlight. 
Such mirrors can create very high temperature’s at their focal point and are used in solar furnaces. Safety is a major issue for such heliostats. . 
These heliostats require motors in 2 directions to control the mirror.  This is a significant cost  
This can be simplified by having one motor to control mirror movement each day and having manual, say, adjustment of the angle of the motor to reflect the season.  
This can be simplified again by using a convex mirror to capture the light through much or all of the daylight hours. Again, manual adjustment of the mirror for seasonal changes would help. 
The disadvantage of this approach is that the light is reflected in an arc, rather than just one direction.  This reduces the intensity and value if the reflected light. However, it can remove the need for a powered mirror.    
This option can be simplified further by having a totally static spherical or  elipsoidal mirror, but this further reduces the power reflected in any one direction. 
Using a saddle shaped mirror.  This could be convex to reflect sunlight through the day.  It could have a concave shape at right angles to that to concentrate the solar energy, to compensate for the energy dispersed by the convex direction. Care is needed to not create too much heat at the focal arc of such a saddle shaped mirror.  This could be done by deliberately linearising the concave profile to spread out the location of greatest solar power and avoid serious danger.  
I believe such a saddle shape mirror located outside could achieve useful daylighting in many buildings if well designed.  
Has this saddle mirror option been considered and calculations been done to demonstrate it’s viability?
I believe there must be some original research that would identify some scenarios where this could be useful.
