Energy consumption data
Concerning the energy consumption data, please collect the following information:
Which kind of the following energy, or energy sources, have been consumed in your building?
the type of gas that is used has to be specified using the drop down option. There is a choice of natural gas, liquefied gas and Biogas
it is assumed that light fuel oil is used
the type of coal that is used has to be specified from the options of Anthracite and Brown Coal.
further information on district heating has to be specified. Please fill your data in MWh (see figure 6)further information on district heating has to be specified
the type of wood that is used has to be specified using the drop down options of logs, pellets or chips.
this line concerns the non-electrical energy production by a solar collector, e. g. for hot water
this line takes into account electricity that is purchased with supply contracts that do not contain an agreement about the contribution of specific primary energy sources to the overall energy mix. Please note that if you do have the distribution data for your energy supply you can specify this in 12.
By default the calculation instrument assumes that wind power and hydro energy each contribute 50 % to the overall energy mix since both are the most frequently used renewable energy sources for the production of electricity.
this line concerns the electricity production using photovoltaic (PV) cells
you do not need to specify the type of your photovoltaic cells as the calculation instruments assumes that the system consists of polycrystalline silicon
If you sell all the electricity that you produce: you have to specify here your PV electricity production (kWh). In addition, you must subtract the energy produced by the PV panels from your real electricity use (kWh on your electricity bill), then put that amount in the “conventional electricity purchased”.
# Example: your photovoltaic cells produce 10 000 kWh and your electricity bill is 15 000 kWh. You have to put 10 000 kWh i n the “Photovoltaics” category and 5 000 kWh (= 15 000 – 10 000) in the appropriate electricity (conventional or green ) category.
If you only sell the surplus you are only required to enter your electricity consumption.
What is the allocation of your energy consumption regarding the different end uses?
Please use the following categories of end use:
Other including lighting and equipment (e.g. office equipment like computers, fax or photocopiers but also pumps or canteen and workshop equipment)
Please read the following carefully:
If you are not sure for which purposes an energy source was used, please fill in the field showing the total annual consumption. Please ensure that you either fill in the exact allocation or the total consumption!
Only enter consumption data in kWh, except for district heating, which requires data to be entered in MWh .
If you use gas and if you already have the data in kWh, please ensure that they have been calculated using the lower heating value (LHV). If they are based on the upper heating value (UHV), please calculate the consumption using the conversion factors .
- Table 7 : General conversion factors (appendix 2)
Round up all data entered to whole numbers and leave out spaces between the numbers!
Example A: Myatt Primary School
The building has consumed 210.000 kWh of natural gas in 2003. Thereof, 200.000 kWh was used for space heating and 10.000 kWh was used for water heating. The single numbers have to be entered whereas the total amount must not be entered. If the specific allocation of the use of gas was unknown the total amount has to be entered in the corresponding column.As the use of electricity that has been conventionally bought is unknown its consumption of 150.000 kWh is entered in the column containing the total amount.
