Difference between Total Electricity and Electricity

[Yahya]

Hi there,

In VistaPro when I click on 'Total Electricity', Two variables apear: one is 'Electricity' and the other is 'Total Electricity'!. Both results are identical! My first anticipation is it's because I don't have CHP in my model, is this right?

By the way, also when I click on Total Energy, I get two different results. I figured out that Total Energy (note that one is with capital e and the other is with small e) includes PV generated and 'Total energy' doesn't. Could be best if there is a different naming or maybe a clearer definition on the Guide Thanks.

Regards,

Yahya

The variables get a bit confusing, and in my opinion need some cleaning up, as you have seen. I'd recommend just skipping those altogether and clicking on the new Energy Breakdown tab, which is much clearer.

I think the reason for the different values and spellings is that various modules and navigators require specific variables, and they all got lumped in there, and are sometimes duplicated. In general you can dig down into other sub-energy variables to find out what is included in the 'total' variables, but I find this a pain.

I would like to understand this option "Energy breakdown-Electricity".
I would like to know whether this is the amount of electricity which is consumed in 1-meter square by the building (Because, this amount is fixed in all the rooms in the building)

I mean that each one meter square in this building consumes electricity = 28.7 kW (FOR example).

So, in order to calculate the energy use intensity (EUI) which is the energy used by the square meter per year (EUI(kw/h/m2)= total energy consumption in one year/ total gross floor area). I should sum the electricity values (KW) for this building after that I should divide this value by 8760 (total no. of hours per year).

Is that assumption correct?

Thanks a lot
