    from today:

    The electricity primary energy and CO2 factors in DEAP will be updated on Tuesday morning 11th December at approximately 8am to reflect the latest Energy Balance figures from the SEAI Energy Policy Statistical Support Unit (EPSSU). BER assessors will notice the factors assigned to the electricity fuel type in DEAP automatically update provided their PC is connected to the internet. No action is required by BER assessors to obtain these new figures.

    The background on derivation of the figures will be published on the BER FAQ: http://www.seai.ie/Your_Building/BER/BER_FAQ/FAQ_DEAP/Results/What_are_the_electricity_factors_used_in_the_latest_version_of_DEAP.html

    The electricity primary energy factor will be updated from 2.58 to 2.42 and the electricity CO2 factor will be updated from 0.556kgCO2/kWh to 0.524kgCO2/kWh.
    Factors for other fuels (e.g. oil, gas, wood fuels) remain unchanged.






    Good news for those using Heat Pumps to try to comply with Part L ;)

    Correct. That was the conversion factor first introduced with DEAP in '07

    So thats an 11.5 % better conversion factor.


    to those who are not aware what this means...
    For every unit of delivered electrical energy, DEAP multiplies it by 2.42 because of the inefficiencies in the generation of power plants. So that 2.42 kw/hr of energy is needed to produce 1 kw/hr of electricity.

    In other words electrical power generation has increased from 37% efficiency to 41.3%.

    The factor from December of last year to now was 2.58.

    I believe the factor is going to drop to around 2.27 this year (if my calculation are right and algorithm is not changing) based on data for 2012 at http://www.seai.ie/Publications/Statistics_Publications/Energy_Balance/2012_Energy_Balance.pdf

    Strangely it has actually gone up for year 2014 , to 2.45.
    There must be more wind turbines around now compared to last year? :confused:

    Just looking at the stats, they are including 344.9 kilotonne oil equivalent input for wind power. And 69 for hydro.
    Is this input of energy from the wind, or what does it represent?
    If it's from the wind, I would have assumed it would not be in the calculation as an input (ie the energy was not actually "consumed" in the same way a fossil fuel would be)
