Green roof trial on four london offices aims at cutting energy bills


A new scheme involving green roofs is being trialed on four london office roofs – with the possibility of it being rolled out across central London if successful.

Funded by the Greater London Authority and inmidtown, the £35,000 trial has seen the planting of fruit and vegetables on the roofs of four office blocks – with the aim of not only cutting firms energy bills, but also providing them with extra items for their cafeterias.

The six month trail has seen the roofs of Olswang at 90 High Holborn, Cartesian at 8 Gate Street, the Trades Union Congress at 23-28 Great Russell Street, and also Mishcon de Reya at 12 Red Lion Square covered in a variety of plants using what is known as a modular vegetation system.

This sees plants encased in a pocket of recycled material. It is designed to protect the plants, whilst also making it easier to irrigate and transport them.

Inmidtown is an organisation that represents around 570 businesses in Bloomsbury, Holborn and St Giles of London, providing a range of services including recycling and joint procurement.

According to a statement from the firm, if successful, it plans to roll out the scheme across all its members.

The statement also suggests that if rolled out city-wide, green roofs could save London as much as £160m in energy costs.

Inmidtown chief executive, Tass Mavrogordato, said: “This is a truly innovative project that will not only bring a tangible economic benefit to businesses, but show they care about the environment in which they operate.

“Each company will be helping to create a greener, cleaner and more energy-efficient London.”
