Hi,
I am running a model in 2014.2.1.0 and 2015.2.0.0.
In the VE2014 version it passes section 6 2010, in the VE2015 version it doesnt pass section 6 2010.
I have been through all the inputs with both models on screen and there is no difference as far as I can tell.
When I look at the BRUKL's the notional building has lower Energy Consumption figures in the VE2015 version.
Is there any specific reason for this?
Thanks
Luke
2014 - 2015 Section 6 differences
Re: 2014 - 2015 Section 6 differences
Hi Luke,
There would have been a few updates to the NCM Database between the two versions. If you look at the results in VistaPro you should begin to see where the changes are. This is similar to the question below from this old UK Regs in VE 2014 thread
Will my results change from Part L2 2010 in VE 2013 to Part L2 2010 in VE 2014?
Yes, from running the official test cases in both versions we have noticed a change in results for Part L2 2010. This is due to corrections made to the NCM Database issued by BRE which is used for both 2010 and 2013 regulations. We have also made a few updates which are detailed in the VE 2014 release notes.
NCM Template Updates [ID-]: A number of fixes and updates are made to the NCM Templates which affect existing regulations (including Part L2 2010) ApacheSim methods so as to match recent NCM Modelling Guide and NCM Activities Database updates;
Profile values are stored and read to more decimal places to better match precision of NCM Activity Database.
Corrections to some Activities Database values (e.g. Hot Water Consumption rates) are incorporated in the NCM Templates
Plant profiles are corrected to match NCM Modelling Guide rules for plant operation (previously had been tied to occupancy schedules).
We encourage users who have noticed a change in their BER/TER after upgrading and running again in VE 2014 to look at their results in Vista as it will help in understanding why the results have changed.
