Carbon Visuals has created an image to illustrate the energy saving of the highly insulated Coati House at Paignton Zoo. The sustainable building uses recycled plastic, green oak sleepers, FSC timber and 150mm thick black mountain sheep wool insulation so that heating is not required.

Without this insulation the zoo would have installed a 4kW electric heater. The image shows the actual volume of CO₂ that would have been emitted every day or every hour by such a heater.

Paignton Zoo Environmental Park, is a combined zoo and botanic garden in the South West of England that welcomes over half a million visitors a year.
