Energy saving and an energy calculation spreadsheet

[malcolm]

With the energy prices going up a lot I'm planning to get around to the rest of my secondary glazing this summer. I made a spreadsheet a few years ago that helped me with my SAP calculation. I've attached my spreadsheet it in case it might be helpful to someone else. It needs some work. My only deviation from 'The Science' is that my bricks are in lime mortar and will be dry so offer more insulation than cement mortared bricks which will be soaking wet.

Intrigued by the energy cost being the same before and after insulation.

lime mortar isnt always dry but can leach water into the room slowly

on the other reference to cement and lime it isnt all one face like cement but is seperate bricks that are being warmed heated

you would need to look at south facing heat store on extra info
