Eco Boulevard

Excerpt from Brand Avenue

Along a new main thoroughfare in the Madrid suburb of Vallecas, ingenious "air trees" made of recycled gasworks are growing.

Equal parts garden folly, architectural icon, town square, and adaptive reuse, the enclosures are the result of a competition won by Madrid design firm ecosistemaurbano:
Ecosistemaurbano were the winners, having come up with a dynamic and futuristic answer to the two goals specified by the competition regarding the main street of Vallecas: to generate social activity and adapt an open space from the bioclimatic point of view. The architects resorted to urgent action with the aim of creating a sort of linear wood at the centre of the boulevard – a green belt of compact vegetation to be grown in the next 15 to 20 years. In the middle of a young tree plantation along the boulevard, they placed three mock gasworks. These constructions will act as focal points for the social life of the new urban settlement, which to date has no public meeting places. At the base of the three so-called “air trees”, each with a diameter of about 20 metres, a slight hollow will accommodate the normal activities of an urban park.
One has been built thus far. Two more are soon to follow.

Inside, each air tree is distinct: the first air tree has "columns of air" on the outside and climbing vines on the inside; the second will gradually be encased in vines on both exterior and interior surfaces; a third will feature vegetation on the exterior and a projection wall on the interior--a 360-degree theater for public use.

The air trees are also energy independent, offering solar-powered cooling in addition to shade:
The first air tree is the result of 16 hemicycles arranged in a circle, covered with a thermal fabric and supported by a lightweight, easily assembled frame, which is identical for the three large “dynamos”. In terms of energy these theatrical scaffoldings are self-sufficient, relying on a system of photovoltaic solar collection. An evaporation and transpiration plant has been devised for the air conditioning of these open spaces, which are situated in a zone that suffers from very high temperatures in summer. Water pumped into tanks at the top of the cylinders will be redistributed in the lower layers, where it will be vaporised. This will lower temperatures by eight to ten degrees in the small circular spaces, thus making them very pleasant places in which to relax.

Importance of a SQUARE

by whaday 1.30.07

Take a look at "Squares" by Mark Childs, published in 2005. It is a design manual book for urban designers around the concept of the plaza, square, green, etc. (he does discuss other forms of public space and classifies them).

In planning and architecture here in New Mexico, the plaza is a key typology we all must study. No plaza is worth its weight in frijoles without retail to ring the exterior. This is what gives it life. It is the "third place" and provides the excuse for being there at all, let alone a reason to stop.

The typical scenario (not always followed) for the Laws of the Indies settlement requirements included an open rectangle of specified proportions with the church on the north side, government functions on the south and retail on the sides.

Make sure you do consider the role of vendors in public space in some sense, though, They are extremely important in addressing some of the key factors that make public space lively (and are adaptable to locations where a permanent structure may be impractical or costly). Again, Childs' book has lots on this, as does William Whyte and the Project for Public Spaces (based largely on Whyte's writing). Food is especially important, which Childs relates to the psychologist Maslowe's "hierrchy of needs" (meet the most basic needs first).

Mixed-Use Summit

by Jetson Green

Never mind the fact that I'm supposed to be finishing a final for intellectual property, I spent the day at Victory Park and the new Dallas W Hotel, attending the Mixed Use Summit, presented by Commercial Property News and Multi-Housing News. I found the seminar extremely enlightening and educational; I wanted to pass on some nuggets of green development wisdom. If you could provide a nugget, a quote of sorts, on green building and the future of sustainability, what would it be? Comments are open.

On Sustainability:

"If you're not thinking about sustainability, you're missing the boat. TODs, urban development, LEED, etc. There are four reasons you should be thinking about it: (1) it's the right thing to do, (2) your competition's doing it, (3) it adds value to the project, and (4) it speeds up the process." - Ken Ryan, Principal of EDAW Inc.

On LEED:

• "This is where the future is going and groups are getting staffed up with LEED Accredited Professionals, they're getting everyone certified."
• "It's sort of a best practices thing."
• "It's easier to sell LEED to corporate tenants, rather than human tenants, but we're starting to get there..."
• "If you have a project and people are worried about the bottom line, it's tough to go LEED, especially the contractors--they're hard to get on board, but the sales appeal is very big. Developers know the appeal is big and they're trying to figure it out..."
• "In a place like Chicago, with all the requirements they have, you're about 3/4 the way to LEED, so you might as well take the plunge and go all the way."

This conference had many of the best developers and architects from around the country in one room, strategizing and talking about the future of land use, specifically urban development + smart growth, in the US.
