London trials garden rooftops to save energy

A new rooftop trial is taking place in London, which aims to save energy, reduce energy bills and produce fresh food.

While the thought of creating a green office is often placed at the bottom of a ‘things-to-do’ list, the new year represents an opportunity to make some changes. Many of these can be small things, such as introducing a recycling policy at work, setting a limit on printer paper use or by creating a secure bicycle shed or drop-off point.

Many businesses in London are taking part in something slightly different that could reduce their energy output in the years to come – by planting on the roof of their offices.

The Greater London Authority will be funding the trial of 4 rooftops in the capital, according to Business Green, with the aim of rolling it out to other office buildings if it’s successful.

The businesses taking part should see a reduction in energy bills because of a greater level of insulation, while the growth of fruit and vegetables will produce fresh food for their canteens. Furthermore, waste from food at their canteens can go towards fertilising future plantation growth of rooftops, completing the circle of production.

Greener London

Tass Mavrogordato, chief executive of inmidtown, which represents hundreds of businesses in London, told Business Green that it will help firms work together on this issue.

“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,” she explained.

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

Indeed, Business Green reports that introducing green rooftops on the capital’s offices could help save between 3 and 10% of heating costs, with an overall financial saving of £160 million.

With the Mayor of London’s office announcing plans last month to expand and enhance the area’s cycle network to encourage more people to ditch their car for two wheels, the capital continues to look for new ways to become greener.
