Hi All,
I've got a central healthcare AHU (HTM compliant) with heating and cooling with heat recovery serving clinical spaces with terminal reheat. Even with improved heat recovery efficiency, SFP and EER/SEER the cooling and auxiliary energy for BRUKL compliance are unusually high including also ...

Hi Ross,
Thanks for your response and for reminding me of Part L2 Paragraph 2.12, I seem to keep forgetting it :)
I am trying to achieve both Part L and BREEAM Ene 01: 5 credits.
I will pass this to our LCEA who can hopefully help me with the calculation.
I wish an approved/ consistent/ correct ...

Hi IES Gurus,

I am after your views on the following;

I am looking at central gas fired boilers in individual buildings with CHP as lead located in a central plant room serving all buildings.
For BRUKL assessment purposes I have modelled the buildings individually.

What is the best way of ...

Thanks Terence, I missed out this NCM Guide update. I understand is OK to use the previous version for BRUKL compliance but not for EPC production.

Complex, the BER remains the same. The building type is student accommodation (university) with mainly naturally ventilated bedrooms (gas fired ...

Hello everyone,
I just installed the VE 2015 02 version and imported a model that I created in 2014 version.
The issue is that when I run BRUKL compliance with the 2015 version the notional building (heating, aux and lighting) is significantly improved when compared with 2014 with a result a ...

It is quite disappointing that this issue has not been addressed even in 2015 version. And is also frustrating trying to explain to your Client that you input the systems/SFPs correctly but still on their BRUKL output report are not reported correctly and are highlighted in red!

Grumpy Tuesdays!

I have the exact same queries. it would be very beneficial if an experienced user could give us some information

Hi All,

I have problems with getting the 'local extract units serving a single area SFP' to be shown correctly on the BRUKL 2013 output report. Even though I set the SFP to 0.3 it reports it as 0.8 and flags it as red!
I use IES Version 2014.2.1.0 and VE compliance 7.0.2.0.

Does anyone else have ...

Thanks for your reply Ross.

Can you or anyone else give some advice on how to calculate the combined carbon emission factor for a gas fired CHP?

Hi All,

I am hoping that you can help me with this one. If for example I want to see the carbon savings I get from PVs I multiply the energy production from PVs as shown in the BRUKL with the current emission factor for electricity.
Is there any way to directly convert the energy from CHP as shown ...
