Hello,
Just a small query regarding the calculation of the reference building. Should the results of the reference building differ from 2010 to 2013? The NCM doesn't have any changes for the 2010 and 2013 reference building.

Thanks!

Hiya

Yes there can be some minor differences in the reference building under 2010 and 2013 NCM. The methodologies and background assumptions for occupancy and system scheduling have been subtly altered and these can often throw the numbers around a bit.

Yes, but it wouldn't be so much that the heating demand increases 400% in the 2010 reference building to 2013?
