What you see is what we're using

We gather data every 30 minutes from our main utility meters at 2 Marsham Street and daily for nine other buildings. This allows you to see how much electricity, gas and water we are using today, yesterday, this week, this month, this quarter and this year.

Units, Cost and CO2e

If you select cost or CO2e you can see the cost of consumption or the carbon dioxide emissions associated with our energy use.

Data Capture

Data Capture commenced on 9th June 2010 at 2 Marsham Street with six other buildings going online on the 31st August 2011 and further buildings going online from the 1st February 2012.
