Looking for a bit of a steer and to see if anyone else has had the same issue as myself.
I've designed an extension which has in excess of 25% of the floor space as glazing. I am therefore required to improve the energy efficient elements of the rest of the extension to compensate. I'm happy to do this however to get building control to agree it I need to provide them with a report. To me this shouldn't be a too difficult task however two things would be useful. If anyone has had such a report completed in the past a copy would be great. Secondly I am developing a spreadsheet and wouldn't mind passing this to someone who may be able to comment on it etc.
Any help would be great.
