Do you think this will cause problems with the RHI application for ASHP? Any way round it? The man who did the EPC says it cannot be changed.
thanks!

It is true, EPCs cannot be changed.
Did you not get SAP calcs done when you obtained B. Control approval for your design? The (On Con) EPC is the output from the SAP calcs. It may have the correct renewables detailed?

Good luck:smile:]]> RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=202991#Comment_202991 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=202991#Comment_202991 Mon, 02 Jun 2014 12:12:36 +0100 Mikel
You can certainly challenge the EPC if you are not satisfied. I did this for another aspect of the EPC and eventually got some answers, which I accepted.]]> RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=202993#Comment_202993 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=202993#Comment_202993 Mon, 02 Jun 2014 12:47:31 +0100 RobinB RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203664#Comment_203664 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203664#Comment_203664 Sat, 14 Jun 2014 20:59:11 +0100 RobinB RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203668#Comment_203668 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203668#Comment_203668 Sat, 14 Jun 2014 21:48:38 +0100 nigel RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203686#Comment_203686 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203686#Comment_203686 Sun, 15 Jun 2014 17:43:14 +0100 DandJ RHI for solar and ASHP problem with EPC advice welcomed.... http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203779#Comment_203779 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12156&Focus=203779#Comment_203779 Mon, 16 Jun 2014 22:28:37 +0100 Andrew Hugman
The windows can be put in a triple using the default U-Value of 1.8 (post 2002 DG is 2.0) or if you provided evidence (BRFC certificate) the actually U-Value could be in putted.

The walls are the same if you provided evidence including a U-Value calculation then actual data can be used. Otherwise the most likely outcome is 0.25.]]>
