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 in the BRUKL to kgCO2? What's the emission factor of the CHP or is there any way to calculate it?
Thanks in advance.

Re: Carbon savings from CHP in BRUKL
Hi Eleni,
PV is pretty simple in the respect that you can just add it on and it doesn't impact on other systems.
With CHP, it is generally really inefficient at providing heating and hot water compared to almost any other system.
However it more than makes up for this by generating electricity.
Just looking at the BRUKL its very hard to find out exactly what is going on. The CHP will almost certainly be used in combination with other heating / hot water systems. The BRUKL doesn't tell you how these are broken down.
The electricity it generates is easy enough to find on the BRUKL. I believe the fuel factor for 'grid displaced electricity' gets applied to this.
You will need to look through the model in Vista to get your answers.

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?

Re: Carbon savings from CHP in BRUKL
Carbon factors are not really the right way to think about CHP savings since it uses gas and generates electric, although it is technically possible to shoe horn a calculation that would give you an estimate even though it's going to be different for every building and CHP system.elenikalyva wrote: Can you or anyone else give some advice on how to calculate the combined carbon emission factor for a gas fired CHP?
If you want to work out the carbon savings from CHP I would recommend that you run a model using gas boilers only with the notional 2013 parameters applied and then run the same model with the CHP added and compare the two sets of results.
