<div dir="ltr">Hi<div><br></div><div style>Thanks a lot for the advice and the videos. I have discarded the Ecotect idea and will work entirely on ESP-r. I was unable to make satisfactory use of the cookbook because I had not been using it along with the 'Exercises'. I am almost done with both the books and I've enjoyed myself going through them. I shall soon attempt the modelling and simulation and post further enquiries here. </div>

Additional thoughts - 10 zones is more information than a novice will be<br>
used to dealing with. Start simple - learn via a three zone model and<br>
when comfortable with that level of complexity then try your house. It<br>
will take less time and you will make fewer errors.<br>
<br>
And tell us more about 'ventilated porch'.<br>

<div><div class="h5"><br>
ESP-r includes its own CAD functions, it is possible to input the scale of complexity<br>
that you describe via the in-built interface. If you were working with the 'X11' interface<br>
you could take a bitmap image of the plan of the house and use the click-on-bitmap<br>
faciility.<br>
<br>
The Ecotect export facility (unless it has changed) writes to an ancient version of ESP-r.<br>
You do not mention which version of Ecotect you are using. It might be that someone<br>
in the community might have had experience working with an exported Ecotect model.<br>
<br>
Realistically, going through multiple tools just to compose geometry seems like lots of places for the<br>
process to break down and entities to be mis-interpreted.<br>
<br>
I can imagine some roof forms which would be tedious to create - a geodesic dome or a<br>
hyperbolic paraboloid would be examples. Windows - they are just polygons which have<br>
additional attributes which let short-wave radiation pass. Rectangular windows are not<br>
much of a hassle, approximating a round window would take longer. The main issue<br>
is trying to put more than a couple of windows within a single wall. Much better to subdivide<br>
walls if there are going to be lots of windows in a facade.<br>
<br>
Some people adapt to the ESP-r interface, others find it problematic. I attach a link to<br>
a short video showing the modification of a zone to include a sloped ceiling and some of<br>
the in-built trig functions.<br>

<br>
Could you be more specific about the phrase 'I am unable to make satisfactory use of the Cookbook'<br>
Do you need more detail or less detail? Does it miss some topics that are of interest?<br>
<br>
I can send you links to other video tutorials about materials and constructions and<br>
air flow networks if requested.<br>
<br>
Also - it is polite to you give your name when requesting help. Tell us a bit about<br>
what goals you have for your simulation model. It might be possible that you do not<br>
need to represent all 10 zones or you might need more zones to make a model that<br>
is fit-for-purpose.<br>
<br>

Dear Fellow ESP-r Users,<br>
<br>
I intend to investigate the thermal performance of a house having<br>
<br>
one floor,<br>
multiple zones (10 rooms),<br>
multi-layered walls<br>
a ventilated porch and<br>
numerous obstructions.<br>
<br>
After going through some of the threads in the archive I learned that importing/exporting isn't always possible, and when it is there are issues like 'Ecotect models can be exported into ESP-r but shading should be added using ESP-r' and that adding windows and roofs are tricky in ESP-r.<br>
<br>
So, considering the description of the house, what in your opinion would be the best way to carry out the simulation?<br>
<br>
I'm looking for something like 'Build CAD model using XYZ software, add windows using ABC and add the roof using PQR, then import into ESP-r and finally add zone and construction data' - or something like that.<br>
<br>
Also, as a newbie, I am unable to make satisfactory use of the Cookbook and much of what the ESRU site provides. Anyone know of any better sources for tutorials?<br>
<br>
And lastly, I had come across a thread in which someone spoke of testing the Beta version of an interface which would make modelling in ESP-r '80% faster'. Does something like that exist?<br>
<br>
<br>
<br>
Thanks in advance and regards,<br>
S<br>
