Green Wall Design

Ng Sek San was the principle designer of Mao Marilyn and the Big Garden. With a post grad diploma in landscape architecture and a bachelor of civil engineering, Ng Sek San presented this design to the Singapore Garden Festival. Small living wall panels were used to hold individual plants. The plants are uniform in size, but very different in color which makes the design work. I am guessing that the panels are wire mesh stuffed with sphagnum moss to hold the plants. New Zealand is known for its sphagnum moss, and it’s right next door to Singapore.

Because you're worth it



What is it worth to know what works and what doesn't, what's loved and what's hated, in a town or city? In an era of scarce resources, what value is there in citizens becoming co-operators in the development of their futures?

Quite a lot, I'd have thought. Not just because the provision of citizens' time and opinions can help prevent mistakes being made and identify priorities, but also because their active involvement in the creation of place can help motivate and inspire them, and lead them to exercise more control and choice over their futures.

But many - even those with professional qualifications and skills - don't see their opinions as valuable. They don't see how they could make a difference, so put themselves in the position of being done to rather than being doers, and of doing to others rather than seeing other people's imagination and talents as assets.

This week we kicked off the new phase of Bradford's Regeneration Academy with an introduction to placemaking. As part of that workshop we encouraged 130 council officers - from senior managers to junior admin staff... read more >>

Soft Coastal Engineering


In an interview with Metropolis’ POV blog, Jan H. De Jager, a Dutch civil engineer and dike and dam expert, finds fault in New Orleans’ new coastal and storm management system and discusses how “soft coastal engineering” is more effective than vertical walls in combatting sea level rise.

De Jager says the current reconstruction work in New Orleans, which involves rebuilding solid vertical walls, is the wrong way to go. “One of the projects I’ve seen is the storm-surge barrier being built across the New Orleans Inner Harbor Navigation Canal. In my opinion, this is a completely wrong structure. It’s a vertical wall to stop the waves. That thing will collapse when you have another category-five hurricane.” Instead, soft coastal engineering, featuring natural marsh systems, would be more effective...

Why Do Federal Agencies Seek Green Building Certification?

I had never quite understood why federal agencies were so focused on green building certification.  That was, until I read this:

"U.S. agencies are required to have 15 percent of their existing building inventory incorporate sustainable elements by 2015 under Executive Order 13423, signed by George W. Bush in 2007.  

To comply with the order, the Department of Veterans Affairs aims to have 21 facilities reviewed and rated by third-party green building systems by the close of this year.

'Reaching the goal of 21 third-party certifications in 2010 will make VA a leading example of green achievement,' said Secretary of Veterans Affairs Eric K. Shinseki in a prepared statement. 'We will proudly reach and surpass the 15 percent requirement before 2015.'"
In order to demonstrate sustainable elements in its existing building stock and satisfy Executive Order 13423, Veterans Affairs is obtaining Green Globes certification for existing buildings.  As we move closer to 2015, obtaining green building certification for a federal building will be an important step towards an agency's compliance with Executive Order 13423.

The consequences are growing...

Cleveland Mayor to 'jumpstart transformation' with sustainability

Diagram of Cleveland's proposed municipal solid waste to energy processIn his State of the City address last week, Cleveland Mayor Frank Jackson detailed his plans to use sustainability as an economic engine, and a hoped for path out of poverty. Jackson—who convened 700 people to create a vision for a sustainable city last summer at the inaugural Sustainable Cleveland 2019 summit—started to spell out how he is implementing his green agenda.

Most notable from a green jobs standpoint, Jackson announced plans to bring Chinese LED-light manufacturer Sunpu-Opto’s American headquarters to Cleveland, which he expects to create up to 350 jobs. The business community usually define sustainability as producing economic, social, and environmental or ‘triple-bottom-line’ outcomes, and so the city has created a sustainable business model directing its municipal-owned utility, Cleveland Public Power, to be Sunpu-Opto’s first customer.

“The project would create an LED streetlight design for Cleveland...

Urban Resilience for Dummies, Part 2: Failing the Milk Test

Last post I covered some guiding principles for urban resilience planning in the face of climate change and diminishing resources (especially fresh water and oil). Considering these guidelines, what aspect of U.S. metro development stands out as the most ill-advised and risky? Short answer: exurban sprawl.

If the "Great Recession" taught us anything, it is that allowing the unrestrained sprawl of energy-inefficient communities and infrastructure is a now-bankrupt economic development strategy and constitutes a recipe for continued disaster on every level.

"Shy away from fringe places in the exurbs and places with long car commutes or where getting a quart of milk takes a 15-minute drive," was the warning the Urban Land Institute...
