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.
Hi Duncan/Shane,
Thanks for getting back to me. I've uploaded the model.
I don't know how to upload an image. In the criterion 2 section of the BRUKL at the windows section. In the Ua-calc and Ui-calc column I have a U-value of 5.6, the surface where this occurs is on a first floor window.
The surface has three windows. I have checked that they have the correct fabric data assigned to them, when this didn't work I tried to change the windows via global change.
Hi Andrew,
I've checked all windows and type 27 is used throughout - taking a look at this in Glazing Data shows the same u-value as reported in the BRUKL document:
Would appreciate if you could please clarify. Am I missing something?
