A New Way for a Garden to Add Value
Can a garden increase a commercial property's value? Sure, a garden adds aesthetic value, but how about to a property's bottom line? And, how about if the garden is on the side of the building?
Welcome to a concept known as a "Vertical Garden," a/k/a a Vegetal Wall, which was conceived by French scientist Patrick Blanc. (A couple of pictures of existing Vertical Gardens are included w/ this post.) I ran across the concept in the "First Look" section of the Winter/2009 edition of Development Magazine.
According to the article, Vertical Gardens contribute to reduction of greenhouse gas emissions and can also use recycled water, either from grey water from the building or recycled through the collection bay at the bottom. Proponents have also found that a building's insulating properties are increased dramatically.
HOW IT WORKS: A Vertical Garden is composed of 3 parts: a metal frame, a PVC layer and felt. The frame is hung on a wall or can be self-standing. It provides an air layer acting as a very efficient thermic and phonic isolation system. A thin PVC sheet is then riveted on the metal frame. This layer brings rigidity to the whole structure and makes it waterproof. After that comes a felt layer that is stapled on the PVC. The felt is corrosion-resistant and allows for uniform water distribution. Watering is provided automatically, 4-5 times a day, through a drilled hose running along the top of the Vertical Garden. Since there is no soil involved, the water must be supplemented w/ low concentrated nutrients through an automatic device.
According to the article, more than 200 Vertical Gardens have been installed around the world. A check of Patrick Blanc's website shows only 7-8 in the U.S. so far, including installations in Tacoma, WA, and Charlotte NC.
I have no green thumb, but I like the idea b/c it could reduce HVAC costs and it could differentiate the property from competitors.
The success of a Vertical Garden depends on using the right choice of plants according to the local environment. Anybody know what kind of plants might work best in South Jersey? :)
While a Vertical Garden can be of any dimension, it would seem that the highest return would be found w/ a larger building. Obviously, not every type of building would be a good fit, as I doubt that a "big box" would want a garden growing on the side of the building, but I would think that a mid-rise office or multi-family building would work, as would certain retail and public buildings.
Who wants to be the first to grow a Vertical Garden in South Jersey?
