Kind of a tricky situation: a project on Seychelles which is actually one big mountain. A weather file is from the point in a hill - the international airport. This airport is affected by the shadow from the mountain - it is clearly seen from the weather file. The project is in another location on the island, affected by the same mountain but different way, as we see e.g. on Google Earth. The question is - how to correctly calculate solar radiation?

Any news so far in this area? Chance to write a measure for OS? Upcoming breakthrough in new version of E+..?

Have you checked your constructions and material layers? import from gbXML may be tricky - especially when you use imperial units in gbXML. Check any metals in layers (doors as well) - they may cause instabilities in temperature and heat balance calculations. Also the problem may be in epw file, I've had such mistake once, have you tried it on another model?

Depends on what you export. E+ native CSV contains names of variables in the first row, but not their units, this you should know from E+ documentation. If you export CSV from SQL you can export ReportDataDictionary table as a separate CSV, there you see the units. Anyway if you want to receive a beautifully arranged report to present it on a meeting or whatever, you will definitely need some manual work :)

May be it would be better to use the built-in E+ daylight calculation as soon as it provides maps in csv format, where you have illuminance data distributed row-by-row so you can easily read them. SQL exports illuminance point-by-point so you need to figure out how to combine them into rows to get a real "map".

Energy Plus does not support non-horizontal illuminance maps. You may try to export your file to Radiance and do rendering there directly, but not sure which GUI will allow you to visualize the results...
I would create zones for each floor and assign individual maps. 6 is not so many...

If you want to export E+ variables in CSV format you can either apply a measure from BCL (haven't tried it but still) or edit and run the exported out.idf file with option to export variables data to CSV file - this works well. If you want to export Radiance daylight simulation results, then you need to deal with .sql file it provides. Use one of SQLIte database browsers (like this) find a table with daylight results (either maps or for sensors) and export it as a CSV file. Be aware that natively SQLite keeps data as lists of values, not separating them through columns as we used to see in CSV files. You probably will need to format data either before or after the export.

I always thought that table view is the simplest one... I've created a feature request, hope you'll support it. Thank you for comments.

As far as I'm concerned, current release of OS does not read Constructions from gbXML files, as well as loads and even elements names (as you see it uses IDs instead). But NREL announced some months ago that they are going to make OS first software certified against working with gbXML schema. Look forward as I use Revit to create models too. So, the only way is to add constructions manually, but when you don't know what surface where... that's almost impossible...

I noticed that when we press "Apply to selected" button (e.g. apply thermostats for selected zones), in resulting IDF file (out.idf) there are still unique elements for control schedules and thermostats for each zone while temperature setpoints are the same... It leads to inability to use this IDF for further processing and blows up the IDF itself. Wouldn't it be correct to use unique thermostat objects with the same control and setpoints? Or even better to use Zone Lists?

The more questions, the harder to find answers... Yes, the problem is in OS GUI, Sketch Up works slowly but surely. I like tables, they allow (in theory) to manage massive data easily. Spaces, surfaces, zones - we asked for them, pity they don't work when they are really needed... I remember, 2 years ago OS could work with models with 400 spaces (not zones)... E+ runs the model within half an hour for a year simulation, that's appropriate, but to prepare the model it took a whole day. Ok, let's agree, that big models are out of OS scope.

I'm trying to work on a model with 450 spaces and 4500 surfaces. Looks like OS cannot process this... The performance is almost unacceptably low. Last August I worked with the model with 150 spaces and it was ok. Is it Open Studio feature or smthg is wrong?

I wander, if there is a particular reason why zone thermostats and humidistats cannot be imported to Open Studio from IDF? They are relatively simple objects, but reassigning them is really tedious....

I beg a pardon, but it's worth sharing. A colleague of mine Michal Dengusiak has released the first-in-class library to connect Autodesk Revit to TAS simulation software. Details on LinkedIn Generally it uses Dynamo visual programming interface and allows you to update energy model in TAS from Revit data and vice versa writes results to Revit elements (i.e. spaces and zones loads).
