Interior Design Minimalist

From some sneak peeks of the latest update to the Sustainable Sites Initiative (more from L+U here), I was both excited about the next iteration and establishment of more rigorous set of criteria, and a bit curious how it was going to maintain some of the necessary distance, inclusivity and poetry that is lacking in many other site rating systems. I'm not sure how I feel about the new split between the guidelines and the 'case' for sustainable sites



The full text from the Sustainable Sites website:

"The Sustainable Sites Initiative: Guidelines and Performance Benchmarks 2009 is the product of more than four years of work by a diverse group of experts in soils, hydrology, vegetation, materials and human health and well-being. It is expanded and updated from the Guidelines and Performance Benchmarks –Draft 2008, which was released in November 2008. The Initiative developed criteria for sustainable land practices that will enable built landscapes to support natural ecological functions by protecting existing ecosystems and regenerating ecological capacity where it has been lost. This report focuses on measuring and rewarding a project that protects, restores and regenerates ecosystem services – benefits provided by natural ecosystems such as cleaning air and water, climate regulation and human health benefits.

The Guidelines and Performance Benchmarks 2009 includes a rating system for the credits which the pilot process will test for refinement before a formal release to the market place. The Rating System contains 15 prerequisites and 51 credits that cover all stages of the site development process from site selection to landscape maintenance. If you are interested in becoming a pilot project to test this Rating System, please apply here. Feedback from the pilot projects will be used to create a reference guide which will provide suggestions on how projects achieved the sustainability goals of specific credits.

The companion document titled The Case for Sustainable Landscapes provides a set of arguments—economic, environmental, and social—for the adoption of sustainable land practices, additional background on the science behind the performance criteria in the guidelines and performance benchmarks, the purpose and principles of the Sustainable Sites Initiative, and a sampling of some of the case studies the Initiative has followed."

A wonderful addition to the International Urban Garden Competition “Bilbao Jardín 2009”, by Diana Balmori of New York-based Balmori Associates and a design that literally 'climbs the stairs' with a undulating vegetated strip and cor-ten walls splaying out in a wider planter at the lowest landing.

Some of the designers explanatory text, via Bustler: "The garden climbs the stairs, running in undulating lines of different textures and colors. Envisioned as a dynamic urban space; it moves in time and with the seasons. Its lush planting cascades down as though the garden was flowing or melting, bleeding the colors into each other. In one gesture, it narrates a story of landscape taking over and expanding over the Public Space and Architecture, therefore transforming the way that the stairs and the space is perceived and read by the user. It is a garden of contrasts: the contrast between native and exotic plants, between the red flowers and the green grass, between the green grass and the grey paving. In form, the garden engages the horizontal plaza with the rising vertical plane of the steps and the upright gesture of Eduardo Chillida’s sculpture. Like the famous Spanish Steps in Rome, the garden is not only designed for visitors to ascend and descend, but for them to linger, and just be."

It's an elegantly simple composition, and definitely takes advantage of the 'topography' of the stairway and foreshortening perspectives utilized to create a constantly changing perspective of vegetation in a somewhat grand, but otherwise barren staircase area left between the architectural objects.

An interesting urban habitat from Inhabitat, "...Gitta Gschwendtner’s Animal Wall is for residents of all species in Cardiff Bay, UK. This 50-meter wall includes 1000 houses for birds and bats, and also acts as a textural and geometric sculptural divider between a residential development and a river front."

I'm not sure if bats, birds, and other urban fauna are fans of modern brutalism (compared to parasitic organicism or perhaps vegetated blobitecture), but I'm guessing an abode of woodcrete is probably not bad digs, considering the range of urban options that wildlife occupy to make due in the city. These come in 4 different unit floorplans (all studios, furnishings by owner) and at an affordable square foot cost. As visitors move in in the spring, it'll be interesting to see how successful this particular urban housing project will end up.

A recent, somewhat hyperbolic title from Treehugger, "Bad Green: Some Indoor Plants Release Volatile Organic Compounds" provides a snippet from some recent research that mention, gasp, that plants, particularly indoor ones, release volatile organic compounds (VOCs). It's a strange conceptual notion indeed, as there has been much research and information on the ability of indoor plants to improve air quality - including removal of VOCs and reduction of sick-building syndrome. So should we chuck the plant on the desk, and more broadly stop any notion of incorporating plants into buildings in significant ways? Probably not.

Some explanation "But at least four popular varieties of house plants emit their own VOCs, according to the University of Georgia's Department of Horticulture. Scientists there studied plants in glass jars and found 23 VOCs in the Peace Lily, 16 in the Areca Palm, 13 in the Weeping Fig and 12 in the Snake Plant. Sources included pesticides used in production of the plants, micro-organisms living in the soil and the plastic pots the plants called home, researchers say. The emission rates were higher during the day than at night, and several of the VOCs detected are known to harm animals."

It's not necessarily big news that plants give off VOCs... as plants are organically based and release compounds that are volatile (i.e. they vaporize readily into the air) through the normal process of metabolism. In fact one of the more readily occurring VOCs in nature is methane, which is produced in large quantities in wetlands. While not necessarily toxic, it is a player in global warming, so we should probably indict this as well while we're at it.

The difference between naturally occurring VOCs and synthetics are . Also a review of the study results identified that the primary VOCs from indoor plants were terpenoids, which are a somewhat innocuous form that provides a number of uses - and are particularly descriptive in having strong aromas. For instance the smell of such items as cinnamon, cloves, ginger, and eucalyptus is caused by the terpenoids present in these plants. Without these our sensory world would be much more bleak.

Conversely a number of VOCs we are commonly bombarded with indoors, particularly in new construction, are related to paints, adhesives, solvents, cleaning agents, caulks, wood products, carpets and sealants, and their lovely sounding components of toluene, styrene, xylene and ethylbenzene. As it's easy to tell from a fresh walk down the halls of a new (even sometimes low-VOC green) building, as chemicals off-gas from these materials and invade our smell centers in negative ways, something foul is going on. And, as mentioned in the report, it is likely the major issues with VOCs and indoor plants come from off-gassing of worse compounds from the man-made plastic pots, and pesticides used in growing of the plants... as well as microorganisms in soils and growing media.

This is another compelling reason for a holistic transformation of the landscape and nursery industry to include the whole picture and not just assume that plants are good or bad. While this doesn't say that there isn't something to this idea of VOCs from plants (it's natural) - let's not jump to quick and overwrought conclusions about the perils of house plants without a bit of context and further exploration. I think the precautionary principal is fine, but to eliminate indoor vegetation without some more focused study on impacts is pretty poor form, particularly when many materials used in building and landscape construction are known to be bad, yet still are industry standard.

I'm willing to be that when the overall accounting is done, exterior plants and wetlands probably have a net benefit to our environment, and indoor plants will win out in the search for better indoor air quality. Just a hunch.
