So having read the BRE guide to SAP I was wondering where I can get a copy of the spreadsheet?

The BRE SAP web page appears to link to private companies, but not the software or a spreadsheet!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195832#Comment_195832 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195832#Comment_195832 Mon, 10 Feb 2014 14:44:44 +0000 DarylP
The SAP doc is available foc: http://www.bre.co.uk/sap2009/page.jsp?id=1642

However, most approved s/w is available to licensed Assessors, but at a cost.
STROMA may still allow you download their FSAP2009 foc?

But I should point out it is complicated, and can catch out the unwary....

Good luck]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195845#Comment_195845 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195845#Comment_195845 Mon, 10 Feb 2014 16:49:02 +0000 Triassic
Shall have to re-think how I double check the architects SAP calculation, I have a feeling that default values and guestimates may have been used in places - rubbish in, rubbish out!!

The other problem I have is that the proposed new build is L shaped, with one wing being 1.5 story and the other being 2.5 story (lower ground floor being an open fronted basement), both linked by the entrance hall/stairs. So not straight forward.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195852#Comment_195852 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195852#Comment_195852 Mon, 10 Feb 2014 18:10:12 +0000 stones

There is a free download which lets you enter figures and see where you come out - useful to let you play with variables before committing to getting the actual SAP report done. I think there are other free / trial available. This one was certainly pretty straightforward to use.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195859#Comment_195859 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195859#Comment_195859 Mon, 10 Feb 2014 18:52:44 +0000 Triassic Posted By: stonesuseful to let you play with variables before committing to getting the actual SAP report This is the sort of thing I'm looking for.

However that doesn't mean he is using default values where he could be using detailed data.
If he can't produce the EPC at the end of the job then him carrying out the SAP is a waste of time.

Is there any way you can upload the SAP printout with his details blanked out so as not to get the forum into trouble?
That way you might get a few qualified assessors, eg me, having a quick look through it.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195863#Comment_195863 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195863#Comment_195863 Mon, 10 Feb 2014 19:19:11 +0000 Triassic Posted By: neiluI presume your architect is a fully registered SAP assessor She tells me they farm this work out, so I'll be digging a little deeper tomorrow to find out the level of service I can expect.

The main item to look out for to see if they've taken short cuts is thermal bridging, this should be fully calculated rather than using the poor default value of 0.15.
If they haven't used the default 0.15 and used a better (lower) value then chances are they aren't taking short cuts as this is calculation is a pain to do on complicated houses.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195908#Comment_195908 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=195908#Comment_195908 Tue, 11 Feb 2014 13:47:41 +0000 Sigaldry

What does the SAP assessment achieve? From what I've read the original intent was watered down significantly and I'm left wondering is anything in the planning system that has not been watered down to suit big business!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=197273#Comment_197273 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11731&Focus=197273#Comment_197273 Fri, 28 Feb 2014 15:51:10 +0000 Sigaldry
New regulations have a deemed to be compliant package that also serves as a good level to pitch compliance from.

From extensive SAP modelling, those levels are about right under SAP2012 - and seeing as L1A 2013 is only 6% better than L1A 2010, the levels aren't significantly out from current levels.

You need to get design assessments done before you start work on site anyway and it's a good idea to get a competent assessor involved from the outset imho.

You could try and get an assessor to use STROMA's free to download software if you want and request copies of the files used for design assessments so you can 'have a play'.]]>
