SBEM Model High Heating Energy Consumption

Hi Guys,

I'm working on a large Part L model which is having an issue with high heating energy consumption.  In the BRUKL report the glazing U-values are sitting at 5.6 but the glazing in fabric data is set to 1.1.  I have checked the glazing through CAD input, global change and reset the calc on the Part L software.  Would you be able to take a look at it for me?

Thanks 

Andrew.
