The stock-averaged value accounts for the fact that appliances in current use are models that have been produced and purchased in previous years. Over these years the energy consum…
The 'British thermal unit', or 'Btu', is a unit of energy equal to just over 1 kilo-joule (kJ). This unit has been generally superseded by SI or SI-derived units (e.g. J, kWh) for …
Note It most cases it is preferable to create a profile item in /home/energy/quantity and set its season value rather than a creating a profile item in this category. Explanation P…
The quantity category contains emission factors for all major fuels and electricity generation. Although you can create profile items in the electricity and electricityiso categori…
The Carbon Reduction Commitment (CRC) Energy Efficiency Scheme (formally known as the Carbon Reduction Commitment) is the UK's mandatory climate change and energy saving scheme. Th…
Life cycle methodology, materials. Calculates embodied energy and carbon dioxide (CO2) and CO2e emissions based on the quantity of materials used (by area). Scenarios include paint…
'Heating values' 'Heating values' (or 'calorific values') are measures of the amount of energy contained within a given quantity of fuel. Heating values are therefore expressed in …
Life cycle methodology, materials. Calculates embodied energy and carbon dioxide (CO2) and CO2e emissions based on the quantity of materials used (by mass). Scenarios include speci…
This data represents actions that result in reductions of CO2 emissions. These tips make broad assumptions about typical usage of various items in the UK. Given detailed informatio…
The data in this category is used to determine the emission factor to apply to electrical device usage based on the country specified in metadata profile item, defaulting to the UK…
Life cycle methodology, concrete. Calculates embodied energy and carbon dioxide (CO2) and CO2e emissions based on the quantity of concrete used. Scenarios include standard mixes, b…
Fuel combustion methodology. Calculates direct carbon dioxide (CO2) emissions associated with stationary fuel combustion and electricity usage. Applicable to the UK government's Ca…
The Standard Assessment Procedure (SAP) was developed by the UK Government's Department for Environment, Food and Rural Affairs (DEFRA) along with the (building industry funded com…
This category contains data on the CO2 intensity of electricity supplied to the UK grid by specific providers. Annual values for emissions intensity (i.e. kg CO2 per kWh) are avail…
Here the CO2 emissions are calculated from the energy consumption (default units kWh/year) entered by the user, multiplied by the CO2 produced per kWh dependent on the state select…
