Rating green landscapes (but not for color)

CAMPRIELLO:
For decades, some building owners have welcomed an evaluation their building on a range of criteria around issues of environmental quality. Board inspectors mainly judge a building’s interior—how efficiently water and electricity are used. They evaluate indoor air quality. But for the outside of the building, inspectors look at just one thing: is stormwater is routed in such a way to prevent flooding. And some landscape architects say it is time for inspectors to put more emphasis on the design of the exterior of buildings and the land on which they sit.
Leonard Hopper is one. He teaches landscape architecture at City College at New York School of Architecture. He says the current inspection system, known as LEED, with its focus on buildings, neglects other sustainable practices.
AX HOPPER (9.4 seconds):
It turned out you could have a very well designed landscape that actually would not be suitable for any sort of LEED recognition at all unless it was associated with a building.
CAMPRIELLO:
Hopper says the problem is that there’s no incentive, or recognition, for land developed in an environmentally friendly way. That’s changing. A few years ago, a consortium of universities, landscape architects and botanic gardens joined together to create something called Sustainable Sites Initiative, with a rating system for landscapes—standards separate from current standards for buildings.
Hopper says sites could be certified based on sustainability, regardless of whether a building is there, or not.
Heather Venhaus, of Lady Bird Johnson Wildflower Center at the University of Texas at Austin, is the project manager for this new landscape initiative. She says in an ideal future, buildings and their surrounding landscapes will be rated not as separate spheres, but on the way in which they compliment each other.
AX VENHAUS (15.8 seconds):
So with those properties that do have have buildings, you’re looking for a symbiotic relationship between the building and the landscape, how can waste of one become a resource for the other, and how can there be mutual benefits to achieve the sustainability.
CAMPRIELLO:
One mutual benefit, for example, is how wastewater might be filtered and reused for landscape irrigation. Thoughtful landscaping can help prevent floods. Rooftop gardens can cool buildings. Trees can shield a structure from wind.
Increasingly, technology is being used to chart and map elevation changes and watercourses. This enables high-tech designers to create wastewater systems that prevent flooding. Professor Hopper says increasingly the curriculum is bringing students of architecture and landscape together into the same classroom.
AX HOPPER (19.5 seconds):
So they’re beginning at a very early stage, in their second year, to begin to understand that stormwater management, and orientation and site analysis and all kinds of environmental factors play an important part in not only siting their building, but in designing their buildings, as well.
CAMPRIELLO:
Hopper says technology is advancing green initiatives in other ways, too. He says students have access to an increasing number of environmentally friendly building materials. This year, for example, he’s teaching students how to work with permeable pavements.
The market is catching up with green designers, too. Jim Lapides with the American Society of Landscape Architects says developers can now apply for government funds and tax credits if their property is environmentally friendly. And, he says, there’s a certain amount of cache that landscapers have over the competition if they propose a sustainable site.
AX LAPIDES (14.3 seconds):
That’s how you differentiate your project from someone else if you’re looking to give yourself an edge if you’re getting something approved, if it’s going to be a minimal, if not positive benefit, to the environment: it’s important.
CAMPRIELLO:
Lapides says business owners are beginning to reap the benefits of going green, too. Landlords can charge more rent if they own high-tech, green buildings. Increasingly, tenants want to live and work in buildings that make them feel like they’re helping the environment.
Going forward, landscape designs will be rated differently depending on where they’re located. Heather Venhaus says this will reflect the varied environmental concerns across the country.
AX VENHAUS (15.7 seconds):
And so it may be that in one region, water may be more of an issue than air quality, so in that region, the water points will be ranked higher than the air quality points, and it may be vice versa in other areas.
CAMPRIELLO:
Landscapers say rating their sites should have happened long ago. But agree, when it comes to the environment, it’s better late than never.
