School Roof Declared a Nature Reserve

The Bauder Biodiversity Roof on the Sharrow School is the First Green Roof in the Country to Achieve Nature Reserve Status.

The Bauder green roof on Sharrow Primary School in Sheffield is declared a Local Nature Reserve. The school will be the first green roof in the country to achieve this status - a fitting accolade for a school that defies traditional ideas of what a school should be.

Restricted ground space opened up the opportunity to create green roofs at three levels for play space, 44m² of outdoor classrooms and a 1200m² biodiversity roof designed to replicate a meadow, complete with cornflowers and other urban plants. It is also a haven for birds and other kinds of wildlife, with rotting tree stumps provided for many kinds of insects. All of roofs are used as a learning resource with curriculum-friendly uses for all the children.

Sharrow Primary is also now Sheffield's greenest school, with a heating system powered by warmth coming up from deep in the earth, toilets flushed by rainwater. The Bauder roof works on a technical level, sorting water run-off problems and assisting in the control of storm water, humidity, noise, heat and pollution. Additionally, the roofs incorporate a BREEAM A+ rated Bauder waterproofing system with 120mm of PIR insulation to achieve a U value of 0.2W/M² constructed on a concrete deck.

All in all, the Sharrow School is a real testament to what can be achieved and is a landmark construction that raises the benchmark.
