Bring back SAP calcs in IES

[RossThompson87]

Recently I have seen a large amount of high rise apartment buildings coming through as possible projects.

Invariably these are designed with lots of glazing, sliding doors onto balconies etc. so overheating modeling is important.

This means making a 3D IES model of all the flats and applying construction details etc.

Of course SAP calculations are also required. To the best of my knowledge there is no SAP software with a decent 3D CAD input.
So you end up entering areas of walls, windows etc. manually.

On large projects this can take literally days. Then if the Architect changes the design, the SAP models and IES overheating model need updating. The process is very inefficient.

If IES could have a feature for handling this sort of building, the time saving would be huge. I've asked the question previously and been advised there is a link to JPA designer. But it simply can't handle complex geometry.

I'm not sure if anyone else has had more luck?

I remember IES including SAP a few years ago. So surely the old code could be updated?

As we come out of recession we are only going to see more and more of these developments. And there must already be a huge market for this feature.

IES is able to export its geometry and relevant set-up information to a SAP assessment software called JPA Designer. You need a license for this export feature so give IES a shout and I'm sure they'll fill you in.

I haven't used this link for several years. When they first introduced it it worked very well. There were a few bugs the last time I used it so if you go down this route I'd do a few test calculations before trying anything too important.

Hi John,

I had a play with the JPA designer link a year or so ago. I couldn't get anything to export correctly, not even a simple box with one window!

Perhaps I'll get another trial and see if I have any more luck.

Thanks
