Solved: Unusual results in lighting analysis (extremely illuminated)

Anonymous · ‎06-04-2019

Hello,

I have been using Lighting Analysis from Insight for a while, and in the last few days, I am having some strange results in the Illuminance Analysis.

It all started when I did the update of your latest version of Insight (Insight_Addin_2019_v3121) and I started to receive a “Warning Rooms: your project has no rooms…”, although I had rooms, and before doing the update the analyses were doing great (in other computers the analyses are running ok for the same model). I solved this (after some extensive research) deleting the result files from my computer.

Since then, I have been getting strange results when I proceed with Illuminance Analyses (the Solar Analysis runs normally, for example). What happens is the following:

I have a model that used to work before, then I proceed with the analysis and I get a result like this:

All the rooms that have windows are extremely illuminated, everywhere, even in the corners. The scale goes beyond 10.000 lux.

However, when I run the exact same file on other computer/Revit, the analysis runs normally:

The settings, materials, climate data, location, etc, are all equal.

It happens on every model that I make. In my computer, I always receive an analysis extremely illuminated and on other computers, it runs normally.

Additionally, today, when I decided to execute a previous analysis that had “normal” results, the warning sign popped up again (like the image below) and now I can not run any analysis because this sign appears in every project that I have.

Thus, can you help me please to solve these issues? I have some urgency on this matter.

I appreciate your attention.

Kind regards,

Filipa Correia

The latest installer is 'Insight_Addin_v4012' available at https://insight.autodesk.com/oneenergy/Landing/Download. If you get the old version from there, then you need to clear your browser cache.

Try that version, then send me the log file folder for the project from <mydocs>/Autodesk/RevitDaylighting. You can send it to david.scheer@autodesk.com.

In 3.122, the 'Rooms' warning sometimes came up inappropriately when there was a problem connecting to the cloud results. If you are having problems on a particular computer, then the issue is likely with cloud service connection due to firewall settings or something. https://forums.autodesk.com/t5/lighting-solar-analysis-forum/ports-and-proxies-for-lar-and-rendering...

The log files will tell all.

Hello David,

Thank you for your reply.

I've already installed the new version (after cleaning my browser cache), but I keep receiving error messages.

Thus, I've sent you by email my log file folder, like you said, for you to check the files.

I appreciate your quick response and thank you for the help.

Kind regards,

Filipa Correia

Got your email. We're looking into it and this issue is top priority right now.

If you can send me your model with the old and the new runs in it, that would be helpful too.

Here's the likely solution to the apparent over-illumination issue:

It looks like your results are using the Daylight Factor display style, with the color increments in the single and double digits. If the analysis run was not done using the 'Daylight Factor' sky model, then the point results will be in the range of illuminance rather than % daylight (daylight factor).

Try out a regular display style, and/or do another run and use the Daylight Factor Sky Model (under the environment time/date settings in the Lighting run dialog).

One more note:

While it's not the case with this model, over-illumination is also often caused by a model that has materials with Self Illumination turned on in the Appearance properties. Always check your materials in use for this property and turn is off or replace the material. Self illumination will provide additional illuminance beyond that from daylight.

Also check that electric lighting is overridden in the Lighting settings.

Also check that the section box is set to be overridden in the Lighting settings, or turn off the Section Box in the _InsightLighting Model View.

For the benefit of other Forum users, I want to summarize the solutions we found for the issues presented here:

Overlit results:

The analysis was using a Daylight Factor sky model, but an illuminance analysis type. DF sky has a range of 0 to 100, while illuminance has a range of 0 to 6000+, so the DF results were all one color.

Failed to download results:

For some non-US users on work networks, the new release v4.012 using the new v2 Rendering engine was having problems accessing the cloud results. A new version 4.031 of the Insight addin is posted to the Insight downloads page that seems to solve this issue for all customers I've worked with so far.

Also FYI the new v4.031 includes a formal Daylight Factor analysis type that automates the results display styles, average daylight factor calculation, etc. It's a beta version, but fully functional, so we welcome your feedback to flesh it out for users of ADF, BREEAM, etc.
