The company with the catchy name ‘Useful Simple Projects‘ is “a design led consultancy [that works] with organisations and on major urban development projects to develop sustainability strategies, and identify opportunities for innovation”.

Here is a Sankey diagram they did for an energy strategy study for University College London’s Bloomsbury Campus.

Values are probably for a year. The Sankey diagram shows energy consumption in GW (red and blue arrows). The UCL campus has a cogeneration plant, so heat (green arrow) can be produced and distributed by district heating grid.

The numbers in grey show the carbon emissions in tons of CO2 linked to the energy consumption (most likely using characterization factors for electric energy production in the UK and for provision of natural gas). UCL has a low carbon strategy for the next years and this study helps them to review their goals.

This Sankey diagram is … simple and useful.
