Introduction

Welcome to the metering site for the Cambridge University Computer Laboratory.

Here you will find both energy data for the Gates Building and a visualisation tool that produces a graphical presentation of the data. The visualisation works with Safari, Firefox and Chrome. To use with Internet Explorer, install Chrome Frame.

The visualisation tool can be used to explore, identify and compare the energy consumption throughout the building, either to aid in the running of the building or to inform the occupants.

Running the Visualisation

Click "Run Visualisation" on the left to start the tool. The presentation is based on two tree structures: functional and geographic. The same data is presented, only the organisation is different. Clicking on a triangle will expand the tree, exploring by geography or function depending on which is selected. Clicking a square will show the graph for a specific sensor, and clicking a circle will show the graph for the sum of sensors in that section. Dragging the blue selection box on the lower chart will zoom the time scale for selected data in the chart view.

Graphs are presented as instantaneous power. For an explanation of units and cost, see here.

Note that not all circuits below the "Building" main circuit are monitored; this will change as we add more sensors.

The current alpha version of the tool is avalible for use here.

We are currently working with users of other buildings to replicate this system.
