Notes about NUS
How do you calculate the CO2e emissions from a unit of energy used?
Energy retailers and the government produce conversion factors that describe the typical carbon impact of different energy sources. These allow us to take the energy uses (in their respective units), and calculate the approximate carbon dioxide emissions, normally measured in kilograms of carbon dioxide equivalents (kgCO2e). Defra's UK conversion factors may be found at Defra's 2015 Guidelines.
How do you get these data from the building?
Energy data is retrieved directly from Macadam House by CarbonCulture's systems approximately every 10 minutes.
What do the colours on the graph mean?
For buildings, the colours in the graph show approximately how the current level of usage would lead to a given Operational Rating – as set out on a Display Energy Certificate (DEC) – if the performance for a given moment carried on for an entire year. This goes from dark green for ‘A’ to red for ‘G’. We calibrate this using input data used for generating the building’s DEC, together with information relating to 'normal' buildings of its type. If we do not have data for all of the utilities noted in the DEC then the graph will appear in a light-blue colour scale, to indicate that the usage displayed on the graph is not representative of the full energy use of this building. Graphs for communities also show in this blue colour scale.
How much does this organisation pay for its energy?
Prices come from the latest energy bills for National Union of Students. These are of course subject to change, and will be updated by the organisations themselves as tariffs are revised.
