Daylight analysis using Ecotect...
Hi Dan,
Thanks for your post, and apologies for the delayed reply.
The following tutorials may assist you with performing a daylight analysis using Ecotect :
http://squ1.org/wiki/Ecotect_Daylight_Display http://squ1.org/wiki/Daylight_Factor_Analysis_Grid
Regarding cameras, there's no need to set up a camera view in order to be able to visually analyze your results. Everything you need to see is visible via the 3D editor tab once the analysis grid or point display has been calculated. The camera object is used when you wish to export your Ecotect model to an external analysis program, such as RADIANCE.
For future support requests, I recommend that you direct these via the main Square One Research website (http://www.squ1.com/support), as the wiki at this stage is still in its infancy. Also, I don't receive any kind of email notification when someone posts a new comment, so I tend only to find such comments when I just so happen to stumble upon them by accident!
Hope this helps!

Grid and analysis problems
Hi there,
I am trying to perform a lighting analysis (more precisely, a daylight autonomy) for a restauration project at work on the second floor of a building. I modeled the needed floor with lightshelves and surrounding buildins to make the calculations as accurate as possible. However, when it is time to fit in the grid, there are bizarre holes in the analysis grid as well as no results come up after calcuations (it remains at 0%). What have I modeled wrong? I am including the original file of the problematic grid.
Thank you for your help
Radiance error
Hi
I have followed the Radiance tutorial, and I have finished all the wizard steps, then a popup error comes, FATAL ERROR - "can not this functions rayinit.cal"
Doany of you have an idee to solve this problem. (I have Vista on my pc)

About demand and consumption of energy
Hello
how can i know the demand of energy for a room ? (whitout hvac system because it depens of the efficiency of the hvac system) when ECOTECT calculates the monthly heating/cooling loads using a hvac system, it suppose the energy consumption to maintain temperatures into comfort bands ?
Thank you
Ecotect Sky Model
Hello,
Could anybody tell me which sky model(i.e.Isotropic,HDKR,Perez)Ecotect use for its Diffuse radiation simulation? Is there the algorithms posted somewhere?
It would be very helpful. Thank you, Koj
PLEASE DO NOT USE COMMENTS TO POST SUPPORT REQUESTS...
To all users of the SQU1 wiki,
If you require assistance or support with using ECOTECT and other SQU1 software, please don't use the comments section of the wiki to post your support request.
Unfortunately, because of the way the wiki is structured, there is no mechanism by which contributors to the wiki (such as myself) are automatically notified about posted comments. Consequently, if your comment relates to a support request, we generally won't know your comment/support request exists, unless we happen to see it while randomly browsing through the wiki.
The comments section of the wiki is intended for users to post thoughts, contributions, interesting links or other information relating to the wiki post in question.
I can appreciate that it can be difficult at times to receive support with using ECOTECT. However, with the recent acquisition by Autodesk, it is expected that this situation will change over the coming months.
Thank you for your understanding!
Regards,
