Template to perform inventory of buildings, installations and vehicles
In order to measure consumption indicators properly, it is necessary to have a precise inventory of all energy consumption in the municipal area. An inventory must be available of buildings and installations, including public lighting and vehicles. All consumption points (electricity, natural gas and other fuels) must be clearly identified.
EVE has created a template which the councils of smaller municipalities can use to log their inventory and its monthly energy consumption.

Recording of energy consumption in buildings and installations
In order to calculate total consumption in a building in one year, it is necessary to have information on supply of every form of energy. This includes both mains supplies (electricity, natural gas, piped LPG) and others, including external supplies (biomass, gas oil, etc.) and the energy generated in the building itself (solar thermal, photovoltaic).
The criteria for logging this energy is as follows:
Total power consumption is calculated as the sum of the electricity bought from the grid plus the power generated in the building and self-consumed.
For calculating renewable electricity, under the terms of Act 4/2019, Article 17.3:
- Electricity bought from the grid with certificates of renewable origin is not recorded when calculating the percentage of renewables consumed.
- o The electricity of renewable origin generated in the building is recorded when calculating the percentage of renewables consumed, regardless of whether it is for self-consumption or exported to the power grid.
The consumption figures are shown on the gas bill in kWh and cubic metres (Nm3), with the corresponding cost in euros. We recommend taking the consumption figure in kWh (not cubic metres) directly from the invoice.
If there is no meter of useful energy, solar thermal output will be measured by the area in square metres of panels and the hours of use, for the purposes of calculating the renewable energy generated in the building, provided that the installation is in operation. The energy thus calculated will be included in the overall consumption of the building.
The Solar photovoltaic production of a building will be measured using meters, discriminating between self-consumed energy and exported energy.
In order to calculate the renewable electricity, pursuant to Act 4/2019, Article 17.3, any photovoltaic energy generated in the building will be recorded when calculating the percentage of renewables consumed, regardless of whether it is for self-consumption or for exportation to the power grid.
Geothermal and aerothermal
To calculate the renewable energy used, the useful energy of heating and domestic hot water provided by the geothermal system will be measured or estimated and the amount of electricity consumed by the heat pump will be subtracted from that amount. The resulting renewable energy will be added as a consumption figure for the building and will be taken into account in calculating the percentage of renewables consumed. For aerothermal energy, the SPF coefficient must be greater than or equal to 2.5.
In calculating the percentage of renewables consumed, any consumption of biomass may be logged in its entirety, regardless of its source. Biomass consumption should be expressed in kWh of LHV.
Other renewable production facilities not associated with any building
Power production in renewables facilities that are owned by a public administration (hydroelectric, wind, photovoltaic, etc.) and which are not associated with any building may be recorded when calculating the percentage of renewables consumed by the authority.
If ownership of the facility is shared, apply the authority's percentage share in the ownership of the facility.
