Some inspiration from across the Pond

So we like to think we have some great green roofs and walls here in Brighton. Well, we do – but there are lessons we can learn from others including the good citizens of Olympia WA, San Francisco CA and Portland OR.

I was lucky enough to visit this summer – here are some pictures that I hope act as inspiration. We could think, and act, so much bigger.

In the Government complex at Olympia, Washington, is a large area of green roof established on underground car parks. Food is grown for local food banks, tended by Government workers. Some lovely large squash ripening in the sun. There is a large area of wildflower mix (‘Ecolawn’) sown for insects and appearance, and is not watered. This has been established by the Department of Enterprise Services – basically the legal and procurement department!

Nearby, just outside the historic Capitol building, is an area of rain gardens that have been retrofitted to help manage storm water. They are very attractive, and feature seating to encourage enjoyment.

San Francisco Academy of Sciences has a living roof…that is so large it is a visitor attraction in its own right. Not a very good photo, so I’ve stolen one from the website and there are more here.

Also in San Francisco were these mini gardens, usually in shopping areas, that brought planting into very urban settings, softened the street scene and provided fun features and places to relax. A ‘public parklet’ indeed!

Portland, Oregon is well known for its approach to sustainable urban planning and design. The whole neighbourhood we stayed in (Alberta – much like Brighton in its hipsterness) has bioswales and other street level drainage built in. Basically permeable sidewalks (ownership extends to the kerb so householders plant up their strip of sidewalk however they like), roof drainage to ground level, street level swales and other features incorporated into street furniture and traffic calming. Drains are clearly marked to encourage people not to use them for disposing nasties. Much of the sidewalk strip was used to grow veggies and fruit – including a nearby pub that harvested salad crops from the street and boasted of it on its menu.

Here in Brighton, a number of partners including the Council and Environment Agency have launched a pilot ‘sustainable drainage’ scheme in Portslade. Great, but surely we could be bolder?

Madeira Drive – further designs published

New designs have been published for Madeira Drive – attempting to address the restoration of the Victorian arches whilst regenerating the seafront between the Pier and Marina.

This is the latest in a number of ideas – see Michael Doyle’s and the Council backed ideas of Sea Lanes and the ‘Lockwood Project’ that aims to retain and enhance the historic green wall.

Paul Nicholson (Chalk Architects) favours luxury flats and a park at the level of Marine Parade modelled on the New York High Line.

Visualisation here.

Clearly it would mean the end of sections, at least, of the historic planting and established biodiversity on the Madeira Drive Green Wall, but to remain open minded it may create additional valuable habitat and open space for people and wildlife.

Whether this will remain a fanciful sketch, or a vision fulfilled, remains to be seen. Building Green will want to be involved if this gets off the drawing table.

Northfield – Sussex University’s sustainable student housing

We walked round the back of Stanmer Park today, to see the green roofs at Northfield, the campus extension of Sussex University.

Built between 2010 and 2013, the campus features a wide range of features to minimise its environmental impact and running costs. It’s location was controversial – north of the main campus, on farmland, and tucked right up against the South Downs National Park, a Local Nature Reserve and a Site of Nature Conservation Importance – so it particularly needed to blend in and demonstrate a sustainability ethos.

The complex has 272 secure bicycle parking spots (one for every three residents) and eight car parking spaces, four of which are for wheelchair users.

A number of energy-efficiency measures include green roofs (which increase insulation and provide greater biodiversity), low-energy lighting, double glazing and recycling facilities.

The development won a Green Apple Sustainability Award, and received a Breeam Excellent rating.

However, there are problems with the green roofs, which are unusual in being pitched. They look like they are struggling and dying in places.

The planning application noted that “The use of green roofs will be beneficial in blending the development into the landscape from longer views and as an ecological compensation for developing an existing greenfield site.

But it also said “The green roof treatment to the buildings will, if successful, further minimise the visual impact of the buildings as well as providing additional habitat. Sedum roofs often dry out after 2/3 years so there is a concern that the oversown sedum treatment may be short lived and not be fully fit for purpose, and that a slightly deeper root run might provide a more effective substrate on which to establish a chalk downland type flora.”

Although the green roofs certainly do help the development blend into the surrounding countryside, it seems like the fears about the longevity of the Sedum have been realised. Elsewhere in Brighton & Hove failing green roofs have been successfully refurbished.

For example, green roofs have been part of the University of Brighton campus for some time. At the Checkland Building, green roofs have recently been restored following some initial problems with the planting and the limited amount of growing medium installed.

The Checkland Building has been environmentally designed, incorporating night time cooling, natural ventilation, and green roofs to insulate the building from heat loss in winter and heat gain in summer.  As the university sits within the South Downs, a recognised area of chalk grassland (calcareous), the creation of flower rich green roofs provides an important enhancement within the Checkland Building for invertebrates associated with such area.

The Huxley Building and Falmer Sports Centres also have green roofs – these have suffered similar problems to Checkland and have had to be refurbished. Organic Roofs have the contract for this work, and have refurbished the landmark Velo Cafe green roof at the Level in Brighton, which is now thriving.

 

Huge new undulating green roof in Paris

We have a mini version of this in Whitehawk – very mini – and a similar sized roof over the water treatment works in Peacehaven. But at 650 feet long this Parisian roof/park is huge, and way more interesting ecologically.

Part lab, part park, the stunning Espace Bienvenüe was designed by Pargade Architectes and is part of nearly seven hectares that consitutes the green belt of a huge learning center.

A building and a park all in one, the Espace Bienvenüe provides a major recreational landscaped garden for Paris
