new sustainability checklist for Brighton & Hove

The new Sustainability Checklist was published this month. All residential planning applications involving new builds and conversions within Brighton & Hove require a completed Brighton & Hove sustainability checklist.

Good news that it includes a section on Greening, which will help to make green features even more standard in developments.

It asks:

– does the development include green walls; and

– does the development include green roofs;

– how many trees will be planted?

If yes, it asks for more information including the number/area of the features, and the type of habitat green roofs incorporates.

Part 1 of the City Plan states that the Council will continue to measure the success of its policies in part by measuring the area of green wall and green roof established through new development.

Taking a look at the portfolio for the Sustainability Checklist shows that greening is a clear ambition of the Council.

Huge potential for green roofs to improve the centre of Brighton

The first feasibility study and audit of the potential for green roofs in Brighton has been published.

The study examined a study area in Central Brighton, to assess the potential benefits of establishing green roofs.

It finds that 61 hectares of roofs in Central Brighton are suitable for retrofitting with green roofs, in a way which brings nature, summer cooling and storm water management benefits and improves the attractiveness of the cityscape.

This is equivalent to 87 football pitches-worth of new green roof space in the 9km2 area of the city that runs between the West pier and Dyke Road, and from Bear Road to Kemptown.

This area is highly urbanised, is susceptible to surface water flooding, and has limited open green space.

More on the benefits:

  • In terms of urban drainage benefits, it is estimated that 61ha of ‘biodiverse’ green roofs could attenuate between 3507.5m³ and 244,000m3 of storm water. In other words, up to 100 Olympic swimming pools of water would be held back from the city’s roads and drains at peak times. This could have a significant combined effect in reducing flooding and the need for additional, costly, engineering infrastructure.
  • Approximately 2.3MWh of electricity could be saved every year on cooling costs for buildings – via reduced or avoided air conditioning.
  • Greening roofs would also reduce the Urban Heat Island Effect, potentially providing an additional saving in cooling costs in the region of 1.3million kWh per annum.
  • The centre of Brighton would be far more attractive at roof level.

This work should be of interest to planners, architects, developers, environmentalists, householders and city businesses.
