Whole City Foot Print
• Bristol's ecological footprint in 2003 was 191 times the size of the city. If everyone on the earth had the same lifestyle and used the same quantity of resources as the residents of Bristol, we would need three Earths to sustain us.

Know Your Building
• How much energy is being used?– If you don’t measure it you can not
control it.
• When is the energy being used?– Measure consumption over time. Half
hour data
• Who is using the energy?– Examine wastage – e.g. high
consumptions at night.
• Is the amount being used high or low for the building type?– Display Certificate
