Part L 2006 Summer overheating
Can someone please explain to me how an air conditioned office can fail summer overheating on Apache SIM Sbem? Coz I am baffled by it. Ta

SIGH....does anyone from IES ever read these boards? Come on chaps...finger out

Hi Sam,
Not used the 2006 regs in a while but if memory serves AC rooms were exempt from the Crit 3 check.
If you are failing then it would suggest you don't have the rooms set up as air-conditioned spaces correctly.
Check your template assignments.
It's completely different in the 2010 regs (quite rightly too) and if you aren't looking to limit the solar gains you'll be failing big time.
Zap.

Re: Part L 2006 Summer overheating
Zap, that was my understanding too but they are set as air con rooms. Ive checked and checked. But I will check again in fact i'll delete and recreate. Thnx
Ive rechecked and its set as split or multisplit. I'm running apache simulation. The over heating check is on the 25degC for 5% and 28degC for 1%. I cant seem to find the 35w/m2 calc. It still fails a few rooms. Ie they are above the cibse temps. Am I doing this calc correct?

Come on IES answer the question please. Otherwise what is the point of you maintaining a forum on this subject?
Why are spaces served by air conditioning FAILING criterion 3 when they are clearly exempt.

Finger out comment incurs an automatic 2 week response delay from any IES staff. This is really a user forum for those not paying maintenance who don't have direct access to IES Technical Support, the idea is users can assist one another and share experiences and of course the support team here are happy to prompt and chip in along the way.
As it is I don't have much more to add to this discussion myself, seems all rooms are analysed and this is a supplementary report to the main Compliance report which clearly states which rooms should and shouldn't be assessed. My guess is a decision has been made to show the performance of all rooms for your info so you can get a feel for how the building performs and when it comes to any Compliance submission you use this data in your report.
Why do your air con rooms not meet the requirements? Hard to say, maybe the system is limited in some way or other factors are at play to mean that the room is overheating outwith the conditioning profile or the setpoints aren't suitable to meet the targets. Reviewing results for failing rooms in Vista would give a bit more insight if you need it.

We do pay for IES technical but like all tech support i have ever come across it never achieves what it aims to.
I thought this forum was a useful tool for IES and its users. IES is missing a trick here. A forum is a much better way to sort issues out. How many times has tech support answered the same question? One forum post would do the trick and make your tool better and your clients feel more involved and better supported.
Air conditioned rooms are exempt from criterion 3. Thus a VRF cooled space should control to temps and not permit overheating but increase emissions instead. Your software is broken. It fails the check itself, unless I am doing something wrong. Hence the post as I am willing to accept that is the most likely case. Without a good answer our confidence in your software is eroded and we thus consider reverting back to our previous supplier. Thats my MDs view, not mine.
This forum has the ability to make your software better. Its plain daft not to see that. IES should seriously examine how it can better serve its clients. It is being used and tested by thousands of people who have the ability to improve your software for free.
Funny how the same rooms and the same building in Hevacomp pass's Criterion 3. It sees that its air conditioned. Why cant yours?

Re: Part L 2006 Summer overheating
Have you sent this project on to Tech Support so we can take a look? It's hard to say off the top of my head what the problem might be?
I agree with your opinion on the value of a user forum and believe it or not I do appreciate the users of all skill levels who take the time to post on here and occasionally help one another out (although in most cases it still seems to be a place where people come when they have a question, get it answered and then don't bother to post anything back which is a shame).
We have put in place a few tools, the users forum is open to anyone, Knowledge Base which again is free to anyone and of course is somewhere we can post FAQs among other helpful information. Most of our maintenance fee paying customers prefer to deal with the Tech Support team directly via phone or email though and other than feeding Guidance and FAQs through the knowledge base I'm not really in a position to publish all the correspondence we have.
We will always have a real commitment to our paying customers who contact us directly so I'd ask you to appreciate I'm one person moderating this forum amongst other jobs so the more others who post on here the better in my opinion. We can all help each other.
