FotoDocument has been commissioned by BNP Paribas to create a photo essay on a range of clean energy sources from the sun, wind, water and earth to inspire their staff and clients and to affirm BNP Paribas' commitment to invest €15 billion in renewable energy by 2020.

The exhibition launches at BNP's office in central London in January 2018.

The pioneering heat pump technology has been designed and installed by ICAX
at Owen Square Park in Bristol.

Electricity generated by roof mounted solar panels drives a heat pump which captures heat from the summer air and stores it in a themalbank in the ground, until needed for heating in winter.

ICAX uses a heat pump to recycle heat back to the building in winter – without burning fossil fuels.
