The Environment Agency opened its doors to the public to explore one of the UK’s greenest office buildings as part of Bristol Doors Open Day.

The recently completed Horizon House was made from more than 85% of recycled materials.

"Green" features include ground source heat pumps providing 17.5% of the building’s annual energy requirements; over 100m2 of solar panels converting sunlight into electricity and hot water; rainwater harvesting, saving water by up to 70%; natural ventilation through automated windows; and intelligent lighting systems reducing energy consumption.

Paul Leinster, chief executive of the Environment Agency said: "We hope that the achievements here inspire other organisations to reduce their impact on the environment, and also save money."

Visitors also got the chance to see the work the Environment Agency carries out to protect the environment and help reduce the risk of flooding.

The Environment Agency has been doing its bit over the last five years, reducing carbon emissions by 17%, reducing energy consumption in buildings by 15%, and cutting the use of mains water by 18%.
