Hi,

I've been looking at the model you sent us this morning and it does appear to have been built as Thick Walls (I think we probably just have a breakdown in the terminology here, Thin and Thick Walls isn't the easiest concept to describe but your walls have a thickness rather than being modelled as single surfaces so it's a Thick Walls model).

To analyse a Thick Walls you have to be using SketchUp Pro and select the Thick Walls analysis option before running identify rooms so please make sure you're doing that.

However I tried to find rooms on this model and while it didn't crash my SketchUp it did take a up a lot of memory and a few hours later appears to not have made much progress, this is usually a sign that the plug-in is struggling with a complicated geometry. This is a nice big model but I think there are areas that should be tidied as our Thick Walls room finding tool just can not handle this kind of geometry and produce an energy model. I'd suggest you review our white paper (http://www.iesve.com/corporate/media-ce ... 717_v2.pdf) for guidance and check the tools we provide for SketchUp Pro users to assist Thick Wall model creation.

In particular look at how the Thick Walls model should be defined in terms of walls, floors, ceilings and windows/doors, you need to go through your model and make sure all the walls join up and meet each other properly or it will confuse the plug-in and be unable to find rooms. I'd really suggest start with a simpler model too, this one is too big to be using for learning - try just the ground floor for a start and take it from there.

Hope this gets you started, we should really have some example Thick Walls models on the Google Warehouse as the only example IES models are Thin Walls. I'll get on that one day...

Thanks millions for responds
Sorry for previous email


You can consider this email please


The thing that I make sure all boundary are closed

And about my model
I don’t know honestly the building I shall specify it under either thin wall or thick wall

As we have in this building the exterior wall thickness : 20 cm ( because isolated)
Interior wall thickness : 15 cm

So shall I specify building as thin or thick ?

Thank you

Best regards

Hi,

The model you sent is definitely modelled as Thick Walls, I think you have misunderstood this concept. I have emailed you two small example models to demonstrate the difference between Thick ad Thin walls models and to give an idea of how you should build a SketchUp model so that the IESVE plug-in can identify rooms.

This is a key issue for a lot of models we see from users who are inexperienced with the plug-in as they are usually models that look nice in SketchUp but have not been built following the guidance provided by IES in our White Paper and User Guide so when it comes time to actually identify rooms and run analyses problems occur. It's better to practise with some smaller models and decide for yourself which modelling methods to use and how to get good robust geometry form SketchUp to VE.

Personally I much prefer Thin Walls models and find these give the best results (Thick walls is still being developed and is currently only released as a beta) but it is up to users what option they choose, either way the guidance we provide has to be followed.

Thanks for email

That will help

I will try to model it again , I will start by first floor and run the program then will start by second floor

One more questions please about the room
• As I saw in your example that you provide it in the room there is no hole door drawing ? is that mean I don’t have to draw the doors?

Thank you

As long as you have a corresponding surface on the inner edge of the wall to match the door drawn on the outer then it will be recognised by the IESVE plug-in. I created these using the Push Through Windows and Doors tool (available on the IESVE plug-in toolbar, guidance is in the user manual), it adds a hole to the inner surface where there's a window and an opaque surface on the inner surface where there's a door.

Hi Phil

I try to draw the model but I start with ground floor

And I follow same what in the whitepaper and I try to simplify the model
And all boundary are closed to each other
I faced same problem when I run the model ( with I identifying rooms)

Please if you can to quick view the model in the attached file
in the email please can you review it

thank you


Thank you

I had a look at the model and sent you a more detailed response back but as these are common modelling errors I will summarise here for others:

• Roof/ceiling surface doesn't touch the walls, there is a gap between them. Volume must be closed for plug-in to find rooms.
• Open plan areas, gaps left in walls between rooms. Suggest close the volume of each room and then add a material to represent a "hole" (material with 0% opacity). This allows plug-in to find rooms faster.
• Roof/ceiling modelled as one surface, sometimes when do this SketchUp doesn't properly match up the roof surface to the walls. I find it easier to delete the large surface and model each room top boundary surface individually, this way you get better results from room identification.
• Some lines were missing from wall surfaces. When two walls are drawn intersecting sometimes SketchUp doesn't insert a line where they cross but I find the plug-in needs these to rationalise the surfaces and lines in order to find rooms.

General further guidance - model blocks of rooms as Groups then use the IESVE Plug-in Select Groups tool to define these as rooms (whole). You will find the plug-in will identify rooms up to 10 times faster when this is done properly, it really is that beneficial.

Note: I reviewed this model as an exercise to see general areas users are not modelling properly, usually if you want us to review a model in detail like this we would need you to purchase Support Credits (unless you have a maintenance contract with Support). You can find out more here http://www2.iesve.com/Support/Support-Credits.

Hi
Thanks for respond and your cooperation
About the maintenance
How do I know if my IES software licence cover or does not cover maintenance and support?

If not cover how can I get benefit from this?

Thank you

Best Regards
